+==============
+Defining Views
+==============
+
+Views in BFG are typically simple Python functions that accept two
+parameters: :term:`context`, and :term:`request`.  A view is assumed
+to return a :term:`response` object.
+
+A invocation of a view that matches a URL via :term:`url dispatch`
+passes as the context object an object which has attributes matching
+the elements placed into the URL by the ``path`` of a ``route``
+statement.  For instance, if a route statement in ``configure.zcml``
+had the path ``:one/:two``, and the URL at
+``http://example.com/foo/bar`` was invoked, matching this path, the
+context object passed to the view would have a ``one`` attribute withe
+the value ``foo`` and a ``two`` attribute with the value ``bar``.
+
+Declaring Dependencies in Our ``setup.py`` File
+===============================================
+
+Our application will depend on packages which are not dependencies of
+the original "tutorial" application as it was generated by the
+``paster create`` command.  We'll add these dependencies to our
+``tutorial`` package's ``setup.py`` file by assigning these
+dependencies to both the ``install_requires`` and the
+``tests_require`` parameters to the ``setup`` function.  In
+particular, we require the ``docutils`` package.
+
+Our resulting ``setup.py`` should look like so:
+
+.. literalinclude:: src/views/setup.py
+   :linenos:
+   :language: python
+
+Adding View Functions
+=====================
+
+We'll get rid of our ``my_view`` view in our ``views.py`` file.  It's
+only an example and isn't relevant to our application.
+
+Then we're going to add four :term:`view` functions to our
+``views.py`` module.  One view (named ``view_wiki``) will display the
+wiki itself (it will answer on the root URL), another named
+``view_page`` will display an individual page, another named
+``add_page`` will allow a page to be added, and a final view named
+``edit_page`` will allow a page to be edited.
+
+.. note::
+
+  There is nothing automagically special about the filename
+  ``views.py``.  A project may have many views throughout its codebase
+  in arbitrarily-named files.  Files implementing views often have
+  ``view`` in their filenames (or may live in a Python subpackage of
+  your application package named ``views``), but this is only by
+  convention.
+
+The ``view_wiki`` view function
+-------------------------------
+
+The ``view_wiki`` function will respond as the default view of a
+``Wiki`` model object.  It always redirects to a URL which represents
+the path to our "FrontPage".  It returns an instance of the
+``webob.exc.HTTPFound`` class (instances of which implement the WebOb
+:term:`response` interface), It will use the the ``routes.url_for``
+API to construct a URL to the ``FrontPage`` page
+(e.g. ``http://localhost:6543/FrontPage``), and will use it as the
+"location" of the HTTPFound response, forming an HTTP redirect.
+
+
+The ``view_page`` view function
+-------------------------------
+
+The ``view_page`` function will respond as the default view of a
+``Page`` object.  The ``view_page`` function renders the
+:term:`ReStructuredText` body of a page (stored as the ``data``
+attribute of a Page object) as HTML.  Then it substitutes an HTML
+anchor for each *WikiWord* reference in the rendered HTML using a
+compiled regular expression.
+
+The curried function named ``check`` is used as the first argument to
+``wikiwords.sub``, indicating that it should be called to provide a
+value for each WikiWord match found in the content.  If the wiki
+already contains a page with the matched WikiWord name, the ``check``
+function generates a view link to be used as the substitution value
+and returns it.  If the wiki does not already contain a page with with
+the matched WikiWord name, the function generates an "add" link as the
+subsitution value and returns it.
+
+As a result, the ``content`` variable is now a fully formed bit of
+HTML containing various view and add links for WikiWords based on the
+content of our current page object.
+
+We then generate an edit URL (because it's easier to do here than in
+the template), and we call the
+``repoze.bfg.chameleon_zpt.render_template_to_response`` function with
+a number of arguments.  The first argument is the *relative* path to a
+:term:`Chameleon` ZPT template.  It is relative to the directory of
+the file in which we're creating the ``view_page`` function.  The
+``render_template_to_response`` function also accepts ``request``,
+``page``, ``content``, and ``edit_url`` as keyword arguments.  As a
+result, the template will be able to use these names to perform
+various rendering tasks.
+
+The result of ``render_template_to_response`` is returned to
+:mod:`repoze.bfg`.  Unsurprisingly, it is a response object.
+
+The ``add_page`` view function
+------------------------------
+
+The ``add_page`` function will be invoked when a user clicks on a
+*WikiWord* which isn't yet represented as a page in the system.  The
+``check`` function within the ``view_page`` view generates URLs to
+this view.  It also acts as a handler for the form that is generated
+when we want to add a page object.  The ``context`` of the
+``add_page`` view is will always have the attributes we need to
+construct URLs and find model objects.
+
+The context object will have a ``pagename`` attribute that matches the
+name of the page we'd like to add.  If our add view is invoked via,
+e.g. ``http://localhost:6543/add_page/SomeName``, the :term:`pagename`
+attribute of the context will be ``SomeName``.
+
+If the view rendering is *not* a result of a form submission (if the
+expression ``'form.submitted' in request.params`` is False), the view
+renders a template.  To do so, it generates a "save url" which the
+template use as the form post URL during rendering.  We're lazy here,
+so we're trying to use the same template (``templates/edit.pt``) for
+the add view as well as the page edit view, so we create a dummy Page
+object in order to satisfy the edit form's desire to have *some* page
+object exposed as ``page``, and we'll render the template to a
+response.
+
+If the view rendering *is* a result of a form submission (if the
+expression ``'form.submitted' in request.params`` is True), we scrape
+the page body from the form data, create a Page object using the name
+in ``pagename`` context attribute and obtain the page body from the
+request, and save it into the database using ``session.add``.  We then
+redirect back to the ``view_page`` view (the default view for a page)
+for the newly created page.
+
+The ``edit_page`` view function
+-------------------------------
+
+The ``edit_page`` function will be invoked when a user clicks the
+"Edit this Page" button on the view form.  It renders an edit form but
+it also acts as the handler for the form it renders.  The ``context``
+of the ``edit_page`` view will *always* have a ``pagename`` attribute
+matching the name of the page the user wants to edit. 
+
+If the view rendering is *not* a result of a form submission (if the
+expression ``'form.submitted' in request.params`` is False), the view
+simply renders the edit form, passing the request, the page object,
+and a save_url which will be used as the action of the generated form.
+
+If the view rendering *is* a result of a form submission (if the
+expression ``'form.submitted' in request.params`` is True), the view
+grabs the ``body`` element of the request parameter and sets it as the
+``data`` attribute of the page context.  It then redirects to the
+default view of the context (the page), which will always be the
+``view_page`` view.
+
+Viewing the Result of Our Edits to ``views.py``
+===============================================
+
+The result of all of our edits to ``views.py`` will leave it looking
+like this:
+
+.. literalinclude:: src/views/tutorial/views.py
+   :linenos:
+   :language: python
+
+Adding Templates
+================
+
+The views we've added all reference a :term:`template`.  Each template
+is a :term:`Chameleon` template.  The default templating system in
+:mod:`repoze.bfg` is a variant of :term:`ZPT` provided by Chameleon.
+These templates will live in the ``templates`` directory of our
+tutorial package.
+
+The ``view.pt`` Template
+------------------------
+
+The ``view.pt`` template is used for viewing a single wiki page.  It
+is used by the ``view_page`` view function.  It should have a div that
+is "structure replaced" with the ``content`` value provided by the
+view.  It should also have a link on the rendered page that points at
+the "edit" URL (the URL which invokes the ``edit_page`` view for the
+page being viewed).
+
+Once we're done with the ``view.pt`` template, it will look a lot like
+the below:
+
+.. literalinclude:: src/views/tutorial/templates/view.pt
+   :linenos:
+   :language: xml
+
+
+The ``edit.pt`` Template
+------------------------
+
+The ``edit.pt`` template is used for adding and editing a wiki page.
+It is used by the ``add_page`` and ``edit_page`` view functions.  It
+should display a page containing a form that POSTs back to the
+"save_url" argument supplied by the view.  The form should have a
+"body" textarea field (the page data), and a submit button that has
+the name "form.submitted".  The textarea in the form should be filled
+with any existing page data when it is rendered.
+
+Once we're done with the ``edit.pt`` template, it will look a lot like
+the below:
+
+.. literalinclude:: src/views/tutorial/templates/edit.pt
+   :linenos:
+   :language: xml
+
+Static Resources
+----------------
+
+Our templates name a single static resource named ``style.css``.  We
+need to create this and place it in a file named ``style.css`` within
+our package's ``templates/static`` directory:
+
+.. literalinclude:: src/views/tutorial/templates/static/style.css
+   :linenos:
+   :language: css
+
+This CSS file will be accessed via
+e.g. ``http://localhost:6543/static/style.css`` by virtue of the
+``static_view`` view we've defined in the ``views.py`` file.  Any
+number and type of static resources can be placed in this directory
+(or subdirectories) and are just referred to by URL within templates.
+
+Mapping Views to URLs in ``configure.zcml``
+===========================================
+
+The ``configure.zcml`` file contains ``route`` declarations which
+serve to map URLs (via :term:`url dispatch`) to view functions.
+You'll need to add five ``view`` declarations to ``configure.zcml``.
+
+#. Add a declaration which maps the empty path (signifying the root
+   URL) to the view named ``view_wiki`` in our ``views.py`` file with
+   the name ``view_wiki``.  This is the default view for the wiki.
+
+#. Add a declaration which maps the path pattern ``:pagename`` to the
+   view named ``edit_page`` in our ``views.py`` file with the view
+   name ``view_page``.  This is the edit view for a page.
+
+#. Add a declaration which maps the path pattern
+   ``:pagename/edit_page`` to the view named ``view_page`` in our
+   ``views.py`` file with the name ``edit_page``.  This is the edit view
+   for a page.
+
+#. Add a declaration which maps the path pattern
+   ``add_page/:pagename`` to the view named ``add_page`` in our
+   ``views.py`` file with the name ``add_page``.  This is the add view
+   for a new page.
+
+As a result of our edits, the ``configure.zcml`` file should look
+something like so:
+
+.. literalinclude:: src/views/tutorial/configure.zcml
+   :linenos:
+   :language: xml
+
+The WSGI Pipeline
+-----------------
+
+Within ``tutorial.ini``, note the existence of a ``[pipeline:main]``
+section which specifies our WSGI pipeline.  This "pipeline" will be
+served up as our WSGI application.  As far as the WSGI server is
+concerned the pipeline *is* our application.  Simpler configurations
+don't use a pipeline: instead they expose a single WSGI application as
+"main".  Our setup is more complicated, so we use a pipeline.
+
+"egg:repoze.tm2#tm" is at the "top" of the pipeline.  This is a piece
+of middleware which commits a transaction if no exception occurs; if
+an exception occurs, the transaction will be aborted.  This is the
+piece of software that allows us to forget about needing to do manual
+commits and aborts of our database connection in view code.
+
+Adding an Element to the Pipeline
+---------------------------------
+
+Let's add a piece of middleware to the WSGI pipeline.
+"egg:Paste#evalerror" middleware which displays debuggable errors in
+the browser while you're developing (not recommeded for deployment).
+Let's insert evalerror into the pipeline right above
+"egg:repoze.tm2#tm", making our resulting ``tutorial.ini`` file look
+like so:
+
+.. literalinclude:: src/views/tutorial.ini
+   :linenos:
+   :language: ini
+
+Viewing the Application in a Browser
+====================================
+
+Once we've set up the WSGI pipeline properly, we can finally examine
+our application in a browser.  The views we'll try are as follows:
+
+- Visiting `http://localhost:6543/ <http://localhost:6543/>`_ in a
+  browser invokes the ``view_wiki`` view.  This always redirects to
+  the ``view_page`` view of the FrontPage page object.
+
+- Visiting `http://localhost:6543/FrontPage/
+  <http://localhost:6543/FrontPage/>`_ in a browser invokes the
+  ``view_page`` view of the front page page object.
+
+- Visiting `http://localhost:6543/FrontPage/edit_page
+  <http://localhost:6543/FrontPage/edit_page>`_ in a browser invokes
+  the edit view for the front page object.
+
+- Visiting `http://localhost:6543/add_page/SomePageName
+  <http://localhost:6543/add_page/SomePageName>`_ in a browser invokes
+  the add view for a page.
+
+Try generating an error in a view by typing some bad code.  Then hit
+the view.  You should see an interactive exception handler in the
+browser which allows you to examine values in a post-mortem mode.

+Creative Commons Legal Code
+
+*Attribution 2.5*
+
+CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+LEGAL SERVICES. DISTRIBUTION OF THIS LICENSE DOES NOT CREATE AN
+ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION
+ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE
+INFORMATION PROVIDED, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+ITS USE.
+
+/License/
+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. THE LICENSOR GRANTS YOU THE
+RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS
+AND CONDITIONS.
+
+*1. Definitions*
+
+   1. *"Collective Work"* means a work, such as a periodical issue,
+      anthology or encyclopedia, in which the Work in its entirety in
+      unmodified form, along with a number of other contributions,
+      constituting separate and independent works in themselves, are
+      assembled into a collective whole. A work that constitutes a
+      Collective Work will not be considered a Derivative Work (as
+      defined below) for the purposes of this License.
+   2. *"Derivative Work"* means a work based upon the Work or upon the
+      Work and other pre-existing works, such as a translation, musical
+      arrangement, dramatization, fictionalization, motion picture
+      version, sound recording, art reproduction, abridgment,
+      condensation, or any other form in which the Work may be recast,
+      transformed, or adapted, except that a work that constitutes a
+      Collective Work will not be considered a Derivative Work for the
+      purpose of this License. For the avoidance of doubt, where the
+      Work is a musical composition or sound recording, the
+      synchronization of the Work in timed-relation with a moving image
+      ("synching") will be considered a Derivative Work for the purpose
+      of this License.
+   3. *"Licensor"* means the individual or entity that offers the Work
+      under the terms of this License.
+   4. *"Original Author"* means the individual or entity who created the
+      Work.
+   5. *"Work"* means the copyrightable work of authorship offered under
+      the terms of this License.
+   6. *"You"* means an individual or entity exercising rights under this
+      License who has not previously violated the terms of this License
+      with respect to the Work, or who has received express permission
+      from the Licensor to exercise rights under this License despite a
+      previous violation.
+
+*2. Fair Use Rights.* Nothing in this license is intended to reduce,
+limit, or restrict any rights arising from fair use, first sale or other
+limitations on the exclusive rights of the copyright owner under
+copyright law or other applicable laws.
+
+*3. License Grant.* Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+   1. to reproduce the Work, to incorporate the Work into one or more
+      Collective Works, and to reproduce the Work as incorporated in the
+      Collective Works;
+   2. to create and reproduce Derivative Works;
+   3. to distribute copies or phonorecords of, display publicly, perform
+      publicly, and perform publicly by means of a digital audio
+      transmission the Work including as incorporated in Collective Works;
+   4. to distribute copies or phonorecords of, display publicly, perform
+      publicly, and perform publicly by means of a digital audio
+      transmission Derivative Works.
+   5.
+
+      For the avoidance of doubt, where the work is a musical composition:
+
+         1. *Performance Royalties Under Blanket Licenses*. Licensor
+            waives the exclusive right to collect, whether individually
+            or via a performance rights society (e.g. ASCAP, BMI,
+            SESAC), royalties for the public performance or public
+            digital performance (e.g. webcast) of the Work.
+         2. *Mechanical Rights and Statutory Royalties*. Licensor waives
+            the exclusive right to collect, whether individually or via
+            a music rights agency or designated agent (e.g. Harry Fox
+            Agency), royalties for any phonorecord You create from the
+            Work ("cover version") and distribute, subject to the
+            compulsory license created by 17 USC Section 115 of the US
+            Copyright Act (or the equivalent in other jurisdictions).
+   6. *Webcasting Rights and Statutory Royalties*. For the avoidance of
+      doubt, where the Work is a sound recording, Licensor waives the
+      exclusive right to collect, whether individually or via a
+      performance-rights society (e.g. SoundExchange), royalties for the
+      public digital performance (e.g. webcast) of the Work, subject to
+      the compulsory license created by 17 USC Section 114 of the US
+      Copyright Act (or the equivalent in other jurisdictions).
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights
+in other media and formats. All rights not expressly granted by Licensor
+are hereby reserved.
+
+*4. Restrictions.*The license granted in Section 3 above is expressly
+made subject to and limited by the following restrictions:
+
+   1. You may distribute, publicly display, publicly perform, or
+      publicly digitally perform the Work only under the terms of this
+      License, and You must include a copy of, or the Uniform Resource
+      Identifier for, this License with every copy or phonorecord of the
+      Work You distribute, publicly display, publicly perform, or
+      publicly digitally perform. You may not offer or impose any terms
+      on the Work that alter or restrict the terms of this License or
+      the recipients' exercise of the rights granted hereunder. You may
+      not sublicense the Work. You must keep intact all notices that
+      refer to this License and to the disclaimer of warranties. You may
+      not distribute, publicly display, publicly perform, or publicly
+      digitally perform the Work with any technological measures that
+      control access or use of the Work in a manner inconsistent with
+      the terms of this License Agreement. The above applies to the Work
+      as incorporated in a Collective Work, but this does not require
+      the Collective Work apart from the Work itself to be made subject
+      to the terms of this License. If You create a Collective Work,
+      upon notice from any Licensor You must, to the extent practicable,
+      remove from the Collective Work any credit as required by clause
+      4(b), as requested. If You create a Derivative Work, upon notice
+      from any Licensor You must, to the extent practicable, remove from
+      the Derivative Work any credit as required by clause 4(b), as
+      requested.
+   2. If you distribute, publicly display, publicly perform, or publicly
+      digitally perform the Work or any Derivative Works or Collective
+      Works, You must keep intact all copyright notices for the Work and
+      provide, reasonable to the medium or means You are utilizing: (i)
+      the name of the Original Author (or pseudonym, if applicable) if
+      supplied, and/or (ii) if the Original Author and/or Licensor
+      designate another party or parties (e.g. a sponsor institute,
+      publishing entity, journal) for attribution in Licensor's
+      copyright notice, terms of service or by other reasonable means,
+      the name of such party or parties; the title of the Work if
+      supplied; to the extent reasonably practicable, the Uniform
+      Resource Identifier, if any, that Licensor specifies to be
+      associated with the Work, unless such URI does not refer to the
+      copyright notice or licensing information for the Work; and in the
+      case of a Derivative Work, a credit identifying the use of the
+      Work in the Derivative Work (e.g., "French translation of the Work
+      by Original Author," or "Screenplay based on original Work by
+      Original Author"). Such credit may be implemented in any
+      reasonable manner; provided, however, that in the case of a
+      Derivative Work or Collective Work, at a minimum such credit will
+      appear where any other comparable authorship credit appears and in
+      a manner at least as prominent as such other comparable authorship
+      credit.
+
+*5. Representations, Warranties and Disclaimer*
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
+EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+*6. Limitation on Liability.* EXCEPT TO THE EXTENT REQUIRED BY
+APPLICABLE LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL
+THEORY FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY
+DAMAGES ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF
+LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+*7. Termination*
+
+   1. This License and the rights granted hereunder will terminate
+      automatically upon any breach by You of the terms of this License.
+      Individuals or entities who have received Derivative Works or
+      Collective Works from You under this License, however, will not
+      have their licenses terminated provided such individuals or
+      entities remain in full compliance with those licenses. Sections
+      1, 2, 5, 6, 7, and 8 will survive any termination of this License.
+   2. Subject to the above terms and conditions, the license granted
+      here is perpetual (for the duration of the applicable copyright in
+      the Work). Notwithstanding the above, Licensor reserves the right
+      to release the Work under different license terms or to stop
+      distributing the Work at any time; provided, however that any such
+      election will not serve to withdraw this License (or any other
+      license that has been, or is required to be, granted under the
+      terms of this License), and this License will continue in full
+      force and effect unless terminated as stated above.
+
+*8. Miscellaneous*
+
+   1. Each time You distribute or publicly digitally perform the Work or
+      a Collective Work, the Licensor offers to the recipient a license
+      to the Work on the same terms and conditions as the license
+      granted to You under this License.
+   2. Each time You distribute or publicly digitally perform a
+      Derivative Work, Licensor offers to the recipient a license to the
+      original Work on the same terms and conditions as the license
+      granted to You under this License.
+   3. If any provision of this License is invalid or unenforceable under
+      applicable law, it shall not affect the validity or enforceability
+      of the remainder of the terms of this License, and without further
+      action by the parties to this agreement, such provision shall be
+      reformed to the minimum extent necessary to make such provision
+      valid and enforceable.
+   4. No term or provision of this License shall be deemed waived and no
+      breach consented to unless such waiver or consent shall be in
+      writing and signed by the party to be charged with such waiver or
+      consent.
+   5. This License constitutes the entire agreement between the parties
+      with respect to the Work licensed here. There are no
+      understandings, agreements or representations with respect to the
+      Work not specified here. Licensor shall not be bound by any
+      additional provisions that may appear in any communication from
+      You. This License may not be modified without the mutual written
+      agreement of the Licensor and You.
+
+Creative Commons is not a party to this License, and makes no warranty
+whatsoever in connection with the Work. Creative Commons will not be
+liable to You or any party on any legal theory for any damages
+whatsoever, including without limitation any general, special,
+incidental or consequential damages arising in connection to this
+license. Notwithstanding the foregoing two (2) sentences, if Creative
+Commons has expressly identified itself as the Licensor hereunder, it
+shall have all rights and obligations of Licensor.
+
+Except for the limited purpose of indicating to the public that the Work
+is licensed under the CCPL, neither party will use the trademark
+"Creative Commons" or any related trademark or logo of Creative Commons
+without the prior written consent of Creative Commons. Any permitted use
+will be in compliance with Creative Commons' then-current trademark
+usage guidelines, as may be published on its website or otherwise made
+available upon request from time to time.
