""" Compute the crud_model_id and update_field_id fields.
The crud_model_id is the model on which the action will create or update
records. In the case of record creation, it is the same as the main model
of the action. For record update, it will be the model linked to the last
field in the update_path.
This is only used for object_create and object_write actions.
The update_field_id is the field at the end of the update_path that will
be updated by the action - only used for object_write actions.
