*Important Issues Arise When Using Django 1.9
Django 1.9 is lot stricter about collisions in the `related_names` of relationship fields than previous versions of Django. This has brought to light issues in django CMS relating to the private field `CMSPlugin.cmsplugin_ptr`. The issue becomes apparent when multiple packages are installed that provide plugins with the same model class name. A good example would be if you have the package `djangocms-file` installed, which has a poorly named CMSPlugin model subclass called `File`, then any other package that has a plugin with a field named "file" would most likely cause an issue. Considering that `djangocms-file` is a very common plugin to use and a field name of "file" is not uncommon in other plugins, this is less than ideal.
Fortunately, developers can correct these issues in their own projects while they await improvements in django CMS. There is an internal field that is created when instantiating plugins: `CMSPlugin.cmsplugin_ptr`. This private field is declared in the CMSPlugin base class and is populated on instantiation using the lower-cased model name of the CMSPlugin subclass that is being registered.
A subclass to CMSPlugin can declare their own cmsplugin_ptr field to immediately fix this issue. The easiest solution is to declare this field with a `related_name` of "+". In typical Django fashion, this will suppress the back-reference and prevent any collisions. However, if the back-reference is required for some reason (very rare), then we recommend using the pattern `%(app_label)s_%(class_name)s`. In fact, in version 3.3 of django CMS, this is precisely the string-template that the reference setup will use to create the name. Here's an example:
class MyPlugin(CMSPlugin): class Meta: app_label = 'my_package' cmsplugin_ptr = models.OneToOneField( CMSPlugin, related_name='my_package_my_plugin', parent_link=True ) # other fields, etc. ....
Please note that CMSPlugin.cmsplugin_ptr will remain a private field.
Notice of Upcoming Change in 3.3
As outlined in the section immediately above, the pattern currently used to derive a `related_name` for the private field `CMSPlugin.cmsplugin_ptr` may result in frequent collisions. In django CMS 3.3, this string-template will be changed to utilise both the `app_label` and the model class name. In the majority of cases, this will not affect developers or users, but if your project uses these back-references for some reason, please be aware of this change and plan accordingly.
