Hi Carlton,
Tahnk for your analysis.
If you write **disabled=True**, the test fails due to the bug described
here. If you set **disabled=False**, the test fails because there're no
data given to the form.
Here's the code failing only for **disabled=True** :
{{{
from django.forms import ModelChoiceField, Form
from django.test import TestCase
from ..models import ChoiceOptionModel
class ModelChoiceFieldTest(TestCase):
def test_disabled_field_1(self):
opt1 = ChoiceOptionModel(12345)
opt1.save()
class MyForm(Form):
field = ModelChoiceField(
queryset=ChoiceOptionModel.objects.all(), disabled=False,
initial=opt1)
self.assertTrue(MyForm({"field": str(opt1.pk)}).is_valid())
}}}
