deprecate_cmsplugin_filer

A small app with a migration for converting deprecated cmsplugin-filer objects to djangocms plugin objects. Adapted from https://gist.github.com/wfehr/86ac31e8e263b872b746cc721662251e to add link and video plugin capability.

Things you'll want to evaluate before migrating:

• Whether any custom project-level templates are in use for the cmsplugin filer modules. Any special customizations may need to be re-implemented in the djangocms-[file/link/picture/video] templates.

• If you currently are using django config settings such as CMSPLUGIN_FILER_IMAGE_STYLE_CHOICES or FILER_LINK_STYLES, you'll need to copy these as DJANGOCMS_PICTURE_TEMPLATES and DJANGOCMS_LINK_TEMPLATES, respectively. Note: there is a difference in behavior with FILER_LINK_STYLES and DJANGOCMS_LINK_TEMPLATES. The former would simply set a class while the latter expects a corresponding template to be created.

Migration steps:

1. Before running the migration, you can run the following command to make sure you back up the old plugin tables for quick restoring if needed. ./manage.py dumpdata cmsplugin_filer_file cmsplugin_filer_folder cmsplugin_filer_image cmsplugin_filer_link cmsplugin_filer_video > ~/cmsplugin_filer.json

2. Ensure you've installed the new plugins, added them to INSTALLED_APPS, and migrated: pip install djangocms-file djangocms-link djangocms-picture djangocms-video INSTALLED_APPS += ( 'djangocms_file', 'djangocms_link', 'djangocms_picture', 'djangocms_video', ) ./manage.py migrate

3. I recommend also running the following command before and after the migration to get an inventory of the site's plugins and ensure they've all been migrated. ./manage.py cms list plugins

4. Now the small app with the migration can be installed and run: ./manage.py migrate deprecate_cmsplugin_filer

5. If you once again run ./manage.py cms list plugins, you should see the cmsplugin-filer objects have been converted to djangocms-[file/link/picture/video] objects.

6. Do a spotcheck of plugins on the site. This is where you may see errors related to previous FILER_LINK_STYLES that are now expecting corresponding templates to be created for each style.
