Question

I wanted to track my models and their CRUD operations through handling post_save, delete and init signals, and then save entry to the Database about this operation handled.

def handle_model_saved(sender, **kwargs):
  """Trap the signal and do whatever is needed"""
  entry=CRUD_Storage()
  entry.entry='Object \"'+sender._meta.module_name+'\" was saved.'
  entry.save()

Then the funny thing, it is a recursion of saves…

I created model CRUD_Storage, i want to prevent it sending signals like pre(post)init, delete, save.

I don’t think you can prevent Django from sending those signals.

However, you can adapt your handler to not log saves for your CRUD_Storage model.

def handle_model_saved(sender, **kwargs):
    """Trap the signal and do whatever is needed"""
    if sender == CRUD_Storage:
        # return early to prevent recursion of saves
        return
    entry=CRUD_Storage()
    entry.entry='Object \"'+sender._meta.module_name+'\" was saved.'
    entry.save()
