Comment (by aRkadeFR):
More explanation cause I think there's a real problem.
From this code with the good migration etc.
{{{
class Momo(models.Model):
active = models.BooleanField('Active or not',
null=False,
blank=True,
default=True,)
comment = models.CharField('comment',
max_length=1024,
null=False,
default='default comment',
blank=True,)
other = models.BooleanField('Nothing interesting',
blank=True,
default=False,)
class MomoForm(ModelForm):
class Meta:
model = models.Momo
exclude = ('other', )
}}}
now, run into python shell:
{{{
In [3]: form = forms.MomoForm(data={'comment': 'test test comment :) '})
In [4]: momo = form.save()
In [5]: momo.active
Out[5]: False
}}}
This should create an object with the default value of the active flag,
and then hydrate it with the data provided.
Instead, it create with a False value.
From the user point of view, it's not friendly. Cause if in the template
you don't render a form input or your missing a value in the data, it
creates the wrong value.
