#10138 closed (fixed)

Documentation should mention that loaddata does not call custom save or pre_save signals

Description

I have a custom save() method on a model, and I realized it isn't called during the loaddata. The loaddata command creates a set of DeserializedObject objects, each of which contain an object being loaded from the fixture. According to the DeserializedObject.save() method:

def save(self, save_m2m=True):
  # Call save on the Model baseclass directly. This bypasses any
  # model-defined save. The save is also forced to be raw.
  # This ensures that the data that is deserialized is literally
  # what came from the file, not post-processed by pre_save/save
  # methods.
  models.Model.save_base(self.object, raw=True)

In my case, I would like my save method on my model called, but that is easy to remedy for a one time load. In either case, it would be nice to have this documented.

I also found ticket #8399 which talks about the post_save signal being called. I don't know if it is just the pre_save signal and model's save methods not called, but post_save is. Or post_save isn't anymore and that is an old ticket that can be closed.

I will try to write a doc patch soon unless someone else beats me to it.

Has patch: set

I took a first stab at adding the documentation. I would like someone who understands the internals better glance over it to see I described it correctly.
