7266	"""Not specified"" states for BooleanField"	Valera Grishin	nobody	"BooleanField needs additional states ""Not specified"" which means that field wasn't supplied by user when editing ForeignKey'ed model with core=True[[BR]]

Following is an intentionally simplified (for the purpose of demonstration) version of models I need to use in my project:
{{{
!#python
class DataClass(models.Model):
    name = models.CharField(max_length=100)

    class Admin:
        pass

class BooleanAttribute(models.Model):
    owner = models.ForeignKey(to=DataClass, core=True, edit_inline=models.TABULAR)

    class Admin:
        min_num_in_admin = 3
}}}

When editing the DataClass model via Django's default admin interface it will (of course) display 3 (according to min_num_in_admin) BooleanAttibute models too. Submitting the form will cause all three BooleanAttributes to be added to the newly created DataClass instance. And there is no way to say how many of them really need to be saved.

My proposition is too enhance BooleanField with optional second checkbox that will indicate whether value is given or not. And only if it is on then the actual value of BooleanField to be considered.

I'd like to provide patch for this issue but have no idea of where to look at. Any help - hints, suggestions, etc - will be greatly appriciated."		closed	contrib.admin	dev		fixed	BooleanField NullBooleanField nfa-fixed		Fixed on a branch	0	0	0	0	0	0
