How to remove an unselected item in a selected and radio input in Django

Question

If the model field is a selection or a foreign key, the widget on the page is the selected input or radio, if you specify this. Django places "---------" in the first element as an unselected value. How can I override or delete it? I remember reading the way to do this, but I can no longer find it.

Answer 1

See: http://docs.djangoproject.com/en/dev/topics/forms/modelforms/

, "", . , . , . , blank = False ( ).

Answer 2

Django forms doc:

<select>, ModelChoiceField, . ( "---------" ) empty_label, , empty_label=None:

field2 = forms.ModelChoiceField(queryset=..., empty_label=None)

ModelForm, .

Answer 3

If it is ModelForm, just set default=Nonein your model, for example:

choose = models.CharField(max_length=3, choices=choose_dict, default=None)
