CommentFlag incompatible with user-defined comment model

[ukch]

As an example, in models.py:

class SpecialComment(comments.models.BaseCommentAbstractModel):
    # Define fields and stuff here
    pass

If we set this as our model, by overriding get_model and CommentForm.get_comment_model we can create comments fine, but if we try to delete them, we get this error:

Traceback (most recent call last):

    self.field.name, self.field.rel.to._meta.object_name))
ValueError: Cannot assign "<SpecialComment object>": "CommentFlag.comment" must be a "Comment" instance.

The only way I can think of to avoid this issue is to completely rewrite CommentFlag and the deletion method, thus pretty much reinventing the wheel.

One possible solution is to allow the definition of a custom CommentFlag object via a get_comment_flag function or similar.

5 years later, still no fix.

@zmrenwu this is a volunteer project. If this issue is has not been fixed in the last 5 years it's probably because it was not considered critical enough for someone to dedicate time fixing it. If it is to you I encourage you to give a try at submitting a patch for it. Complaining about unresolved issues without providing a solution is not going to get it fixed by itself or encourage someone to work towards it.

Sorry, I don't mean to complain, just a banter. I encounter this issue recently. I am trying to fix it. But if an issue haven't have any responses and discussions for 5 years, I doubt if it will be reviewed or merged by the maintainer.
