==================
29: REST with Ajax
==================
Use Ajax operations to talk to a REST interface.
Objectives
==========
- Populate a list with JSON data
- Update contents with client-side forms that post to REST operations
Steps
=====
#. We are going to use the previous step as our starting point:
.. code-block:: bash
(env27)$ cd ..; cp -r rest_ajax_layout rest_ajax; cd rest_ajax
(env27)$ python setup.py develop
#. Let's first add a Javascript file that implements our browser-side
logic and talks to the REST service:
#. Introduce ``pyramid_jinja2`` dependency in
``rest_ajax/tutorial/static/site.js``:
.. literalinclude:: rest_ajax/tutorial/static/site.js
:language: js
:linenos:
#. Add a ``<script>`` reference to this at the bottom of
``rest_ajax/tutorial/templates/layout.jinja2``
.. literalinclude:: rest_ajax/tutorial/templates/layout.jinja2
:language: html
:linenos:
#. Update ``rest_ajax/tutorial/templates/folder.jinja2`` to include a
modal dialog:
.. literalinclude:: rest_ajax/tutorial/templates/folder.jinja2
:language: html
:linenos:
#. Our views in ``rest_ajax/tutorial/views.py`` need to handle our
REST operations:
.. literalinclude:: rest_ajax/tutorial/views.py
:linenos:
#. Run your Pyramid application with:
.. code-block:: bash
(env27)$ pserve development.ini --reload
#. Open ``http://localhost:6543/`` in your browser and
add (+ button), edit (click link), and delete (click trash icon)
items in the root folder.
