I just released repoze.bfg 0.6.8 with the following features (from the changelog). It also has some backwards incompatibilities. This release mostly fixes sins of old having to do with generating and resolving model paths.
Note that despite my earlier request for dispensation to change ``repoze.bfg.traversal.model_path`` to return a tuple, I decided to make it to continue returning a string. Please read below for slight backwards incompatibilities between the return value of the "new" ``model_path`` and the return value of the old one, however. They are not completely equivalent. 0.6.8 (2009-02-05) ================== Backwards Incompatibilities --------------------------- - The ``repoze.bfg.traversal.model_path`` API now returns a *quoted* string rather than a string represented by series of unquoted elements joined via ``/`` characters. Previously it returned a string or unicode object representing the model path, with each segment name in the path joined together via ``/`` characters, e.g. ``/foo /bar``. Now it returns a string, where each segment is a UTF-8 encoded and URL-quoted element e.g. ``/foo%20/bar``. This change was (as discussed briefly on the repoze-dev maillist) necessary to accomodate model objects which themselves have ``__name__`` attributes that contain the ``/`` character. For people that have no models that have high-order Unicode ``__name__`` attributes or ``__name__`` attributes with values that require URL-quoting with in their model graphs, this won't cause any issue. However, if you have code that currently expects ``model_path`` to return an unquoted string, or you have an existing application with data generated via the old method, and you're too lazy to change anything, you may wish replace the BFG-imported ``model_path`` in your code with this function (this is the code of the "old" ``model_path`` implementation):: from repoze.bfg.location import lineage def i_am_too_lazy_to_move_to_the_new_model_path(model, *elements): rpath =  for location in lineage(model): if location.__name__: rpath.append(location.__name__) path = '/' + '/'.join(reversed(rpath)) if elements: suffix = '/'.join(elements) path = '/'.join([path, suffix]) return path - The ``repoze.bfg.traversal.find_model`` API no longer implicitly converts unicode representations of a full path passed to it as a Unicode object into a UTF-8 string. Callers should either use prequoted path strings returned by ``repoze.bfg.traversal.model_path``, or tuple values returned by the result of ``repoze.bfg.traversal.model_path_tuple`` or they should use the guidelines about passing a string ``path`` argument described in the ``find_model`` API documentation. Bugfixes -------- - Each argument contained in ``elements`` passed to ``repoze.bfg.traversal.model_path`` will now have any ``/`` characters contained within quoted to ``%2F`` in the returned string. Previously, ``/`` characters in elements were left unquoted (a bug). Features -------- - A ``repoze.bfg.traversal.model_path_tuple`` API was added. This API is an alternative to ``model_path`` (which returns a string); ``model_path_tuple`` returns a model path as a tuple (much like Zope's ``getPhysicalPath``). - A ``repoze.bfg.traversal.quote_path_segment`` API was added. This API will quote an individual path segment (string or unicode object). See the ``repoze.bfg.traversal`` API documentation for more information. - The ``repoze.bfg.traversal.find_model`` API now accepts "path tuples" (see the above note regarding ``model_path_tuple``) as well as string path representations (from ``repoze.bfg.traversal.model_path``) as a ``path`` argument. - Add ` `renderer`` argument (defaulting to None) to ``repoze.bfg.testing.registerDummyRenderer``. This makes it possible, for instance, to register a custom renderer that raises an exception in a unit test. Implementation Changes ---------------------- - Moved _url_quote function back to ``repoze.bfg.traversal`` from ``repoze.bfg.url``. This is not an API. _______________________________________________ Repoze-dev mailing list Repozeemail@example.com http://lists.repoze.org/listinfo/repoze-dev
