Re: Save, Signals and Models

Thanks Eric, that worked like a charm. I've never got to use the update, thus I had no idea of its existence, fair enough that is exactelly what I needed. Thank you very much, and other who have answered this thread. Victor Lima 2010/1/16 Eric Chamberlain > > On Jan 15, 2010, at

Re: Save, Signals and Models

I did exactelly that, instead of using id I used the slug, which is also unique, so I skipped it, but the problem still occurs. Either my logic is wrong, or some dumb mistake, but I think that wouldnt work either. Victor Lima 2010/1/15 Mike Ramirez > Add in an if

Re: Save, Signals and Models

Add in an if statement, one that while cycling through the only_me=True list, ignores the current model you're saving. def save(self): if self.only_me: only_me_true = MyModel.objects.filter(only_me=True) for obj in only_me_true:

Re: Save, Signals and Models

I think that will not work,when I call the obj.save() I will inevitably step again into my own save() method and the only_me wont be set as False yet, thus the same problem would occur again and again until I get the maximum depth error. I dont think thats an option, ahev you tested this

Re: Save, Signals and Models

Hey Victor, I can think that a trivial way (I am not sure if it is the best) to do that is to overwrite the save() method of your model: class MyModel(models.Model): title = models.CharField(max_length=100) only_me = models.Boolean(default=False) def save(self): if

Save, Signals and Models

Here is the deal: class MyModel ( models.Model ): title = models.CharField( max_length = 100 ) only_me = models.BooleanField( default = False ) Question: Whats the proper way to guarantee that no matter how many MyModel's are available in the database, only one of them will have the only_me
