Hi everybody, I have a problem with denormalizing a m2m field. For several reasons I want to save a CSV string of all the authors of a text. The authors are manage in an m2m field to auth.user. The changes are made with the admin.
First I tried to override the save() method of the model. This didn't work. Even with first calling save on the parent and doing a fresh query within the save() function I always get the state of the authors before the change. After the save operation I have the correct list of authors in the m2m field but an incorrect serialization in the denormalized charfield. If I then save again (via the admin interface) without changing anything it obviously works. Next I tried using the post_save signal. Same results. Then someone in the channel suggested to override an admin function and I tried overriding save_model. Same results here as well. I don't really know what to do next and I simply don't understand what's going on. When are these m2m relations updated? Is there perhaps a seperate signal. Do I somehow need to resync due to internal caching or something weird like that? I would be very glad for any suggestions in the toppic! Thanks a lot in advance.
