Submitted ticket #8663 for the following:
When a ModelForm? is used to display a form for a Model, the fields
defined with a choices option insert a "-------" value for the first
option when the form is rendered. If you override a field and manually
specify the choices for a Select widget, this "-------" does not
appear as the first choice.
# models.py
from django.db import models
MY_CHOICES = (
(0, 'Zero'),
(1, 'One'),
)
class MyModel(models.Model):
my_field = models.IntegerField(choices=MY_CHOICES)
# forms.py
from django import forms
from myapp.models import MyModel, MY_CHOICES
class MyModelForm(forms.ModelForm):
#my_field =
forms.IntegerField(widget=forms.Select(choices=MY_CHOICES))
class Meta:
model = MyModel
View the HTML for the form with my_field commented out:
>>> from myapp.forms import MyModelForm
>>> f = MyModelForm()
>>> print f
<tr><th><label for="id_my_field">My field:</label></th><td><select
name="my_field" id="id_my_field">
<option value="" selected="selected">---------</option>
<option value="0">Zero</option>
<option value="1">One</option>
</select></td></tr>
Now uncomment my_field in MyModelForm?:
>>> from myapp.forms import MyModelForm
>>> f = MyModelForm()
>>> print f
<tr><th><label for="id_my_field">My field:</label></th><td><select
name="my_field" id="id_my_field">
<option value="0">Zero</option>
<option value="1">One</option>
</select></td></tr>
This value doesn't appear in the 2nd case: <option value=""
selected="selected">---------</option>
