accepts a different ordering of arguments. Previously it was ``(pattern, name, factory=None, predicates=())``. It is now ``(name, pattern, factory=None, predicates=())``. This is in support of consistency with ``configurator.add_route``. - The ``repoze.bfg.urldispatch.RoutesMapper.connect`` method (not an API) now accepts a different ordering of arguments. Previously it was ``(pattern, name, factory=None, predicates=())``. It is now ``(name, pattern, factory=None, predicates=())``. This is in support of consistency with ``configurator.add_route``. - The ``repoze.bfg.urldispatch.RoutesMapper`` object now has a ``get_route`` method which returns a single Route object or ``None``. - A new interface ``repoze.bfg.interfaces.IRoute`` was added. The ``repoze.bfg.urldispatch.Route`` object implements this interface. - The canonical attribute for accessing the routing pattern from a route object is now ``pattern`` rather than ``path``. - The argument to ``repoze.bfg.configuration.Configurator.add_route`` which was previously called ``path`` is now called ``pattern`` for better explicability. For backwards compatibility purposes, passing a keyword argument named ``path`` to ``add_route`` will still work indefinitely. - The ``path`` attribute to the ZCML ``route`` directive is now named ``pattern`` for better explicability. The older ``path`` attribute will continue to work indefinitely. - All narrative, API, and tutorial docs which referred to a route pattern as a ``path`` have now been updated to refer to them as a ``pattern``. - The routesalchemy template has been updated to use ``pattern`` in its route declarations rather than ``path``.
============ Paster Templates ---------------- - The ``bfg_alchemy`` and ``bfg_routesalchemy`` templates no longer register a ``handle_teardown`` event listener which calls ``DBSession.remove``. This was found by Chris Withers to be unnecessary. Documentation ------------- - The "bfgwiki2" (URL dispatch wiki) tutorial code and documentation was changed to remove the ``handle_teardown`` event listener which calls ``DBSession.remove``. - Any mention of the ``handle_teardown`` event listener as used by the paster templates was removed from the URL Dispatch narrative chapter.
for all Chameleon BFG templates by setting a BFG-related Paster ``.ini`` file setting named ``debug_templates``. The exceptions raised by Chameleon templates when a rendering fails are sometimes less than helpful. ``debug_templates`` allows you to configure your application development environment so that exceptions generated by Chameleon during template compilation and execution will contain more helpful debugging information. This mode is on by default in all new projects.
No foreigners were harmed in the coding of this feature.
``bfg_alchemy`` application template's ``MyApp`` model was an integer. This was incorrect. It is now a string.
clean up the SQLAlchemy connection by registering a ``repoze.tm.after_end`` callback instead of relying on a ``__del__`` method of a ``Cleanup`` class added to the WSFI environment. The ``__del__`` strategy was fragile and caused problems in the wild. Thanks to Daniel Holth for testing.
-------- - The ``Configurator.add_view`` method now accepts an argument named ``context``. This is an alias for the older argument named ``for_``; it is preferred over ``for_``, but ``for_`` will continue to be supported "forever". - The ``view`` ZCML directive now accepts an attribute named ``context``. This is an alias for the older attribute named ``for``; it is preferred over ``for``, but ``for`` will continue to be supported "forever". - The ``Configurator.add_route`` method now accepts an argument named ``view_context``. This is an alias for the older argument named ``view_for``; it is preferred over ``view_for``, but ``view_for`` will continue to be supported "forever". - The ``route`` ZCML directive now accepts an attribute named ``view_context``. This is an alias for the older attribute named ``view_for``; it is preferred over ``view_for``, but ``view_for`` will continue to be supported "forever". Documentation and Paster Templates ---------------------------------- - All uses of the ``Configurator.add_view`` method that used its ``for_`` argument now use the ``context``argument instead. - All uses of the ``Configurator.add_route`` method that used its ``view_for`` argument now use the ``view_context``argument instead. - All uses of the ``view`` ZCML directive that used its ``for`` attribute now use the ``context`` attribute instead. - All uses of the ``route`` ZCML directive that used its ``view_for`` attribute now use the ``view_context`` attribute instead.
