BooleanField is forced to be blank=True

​https://github.com/django/django/tree/master/django/db/models/fields#L1017

    def __init__(self, *args, **kwargs):
        kwargs['blank'] = True
        super(BooleanField, self).__init__(*args, **kwargs)

blank is set to True forcibly

I want my BooleanField always explicitly set(without a default value), like this:

myflag = models.BooleanField(blank=False)

but with this kwargs['blank'] =True, Django does not complain if field myflag not set, but try to use default of BooleanField(in 1.7.5, None) which lead to exception when saving~

I think force blank = True makes sense for NullBooleanField, but for BooleanField, we can leave it to user.

Thanks.

See #22282 and #23130 for some related discussion. I'm not sure what the proper resolution is, but I'll accept the ticket since this this has come up several time. We can at least document the reasons for this if it can't be changed for backwards compatibility reasons.

There's an outdated patch in #23130, which I still think is the best solution to this problem. Somehow, I've never gotten around to finishing the patch, but I think it should take no more than an hour of time to get it up to date and pass the test suite.

The ​WIP PR I made for #23130 addresses this.

I think this was fixed with ​https://github.com/django/django/pull/8467 and #29227 . This ticket can be close then?
