Hi,

  When setting HiddenInput on a form widget for an integer model field with choices, in tests I get 'X is not a valid choice' errors.  I'm guessing it's the hidden input returning a STRING and the model expecting an INT.

  I have a model that has....

class Banner(models.Model):

  banner_x = models.PositiveIntegerField(blank=False, default=0, choices=enumerate(BANNER_XS))


And a form that has....

class BannerForm(forms.ModelForm):

  class Meta:

    model = Banner

    fields = ['banner_x']

  def __init__(self, *args, **kwargs):

    kwargs['prefix'] = 'banner'

    super(BannerForm, self).__init__(*args, **kwargs)

    self.fields['banner_x'].widget = forms.HiddenInput()


In my unit tests I always get the error:

    resp = self.client.post('/banner/, {

      'banner-banner_x':0,

    }, follow=True)

<ul class="errorlist"><li>banner_x<ul class="errorlist"><li>Select a valid choice. 0 is not one of the available choices.</li></ul>


Anyone else seeing this?  Works fine via browser, just unit tests are not coming back right.

Which Python and Django versions do you use?

Hi.

Unfortunately 1.7 is unsupported version. 

You should test with 1.11 to see if issue still exist.
