Question

models.py:

class Foo(models.Model):
    ...
    TIME_UNIT_TYPE = (
        ('D', 'Day'),
        ('W', 'Week'),
        ('M', 'Month'),
    )
    time_unit = models.CharField(max_length=1, choices=TIME_UNIT_TYPE)
    ...

forms.py:

class FooForm(ModelForm):
    class Meta:
        model = Foo
        fields = (time_unit,)

When time_unit is rendered in the template, the resultant select element contains a bogus ‘—-‘ option that I don’t need for my app. I can remove this bogus option inside init() or redefine the time_unit attribute inside the FooForm. But I was wondering if there are any other more straightforward ways to accomplish the same.

Answer 1

Try with:

from django.forms import ModelForm
from django import forms as forms

class FooForm(ModelForm):
    time_unit = forms.forms.TypedChoiceField( 
                    required=True,
                    choices = Foo.TIME_UNIT_TYPE
                )    
    class Meta:
        model = Foo
        fields = (time_unit,)

              

Test if this works for you.
