HI All, I'm new in south and I'm wondering how I can merge two models into one. I have a model book which derives from the model media. So book has a media_id_ptr (which is already a pk).
No I would like to merge all attributes from media into book and get rid of media. I was doing the following: 1.) Added all media attributes in the book model, but with _tmp ending. 2.) Created a schemamigration (also creates a correlation table with ending _tmp) 3.) Created a datamigration and copied the attribute value into the attribute_tmp for all existing book objects. 4.) modified the book model to get rid of the _tmp ending. 5.) Created a schemamigration and exchanged (delete/add with rename column) additionally I would like to rename media_id_ptr into id and use it as primary key. But it always fails when I would like to rename the media_id_ptr into id. I have different tables (m2m and normal foreign keys) which point to media_id_ptr. Therefore I have 2 question: 1.) I guess it is not that easy to reuse the former foreign key as a primary key. Is there a best practice to handle that? DO I have to remove the foreign key and add it after renaming for all tables which referenced it before? 2.) Best practice to rename the m2m_tmp table DO I have to delete the unique keys and re-add them after renaming? Thanks for any hints how to solve this issue.
