Wagtail module path updates
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Many of the module paths within Wagtail have been reorganised:
Many of the module paths within Wagtail have been reorganised to reduce duplication - for example, ``wagtail.wagtailcore.models`` is now ``wagtail.core.models``. As a result, ``import`` lines and other references to Wagtail modules will need to be updated when you upgrade to Wagtail 2.0. A new command has been added to assist with this - from the root of your project's code base:
.. code-block:: console
$ wagtail updatemodulepaths
Or, to run from a different location:
.. code-block:: console
$ wagtail updatemodulepaths /path/to/project
You are advised to take a backup of your project codebase before running this command. The command will perform a search-and-replace over all \*.py files for the affected module paths; while this should catch the vast majority of module references, it will not be able to fix instances that do not use the dotted path directly, such as ``from wagtail import wagtailcore``.
The full list of modules to be renamed is as follows:
