.save() in django

The .save() method in Django performs an SQL UPDATE query on the database for the model. First, it calls the pre_save signal. Then, it determines whether the model is being saved for the first time. If the model is being saved for the first time, it calls the pre_save and post_save signals. If the model is being updated, it calls the pre_save and post_save signals. After that, it calls the save_base method, which performs the actual saving of the model. Finally, it calls the post_save signal.
