Django:使 ModelForm 中的某些字段 required=False

Question

如何使 ModelForm 中的某些字段 required=False？

如果我有:

class ThatForm(ModelForm):
  class Meta:
    widgets = {"text": Textarea(required=False)}

或者如果我有:

class ThatForm(ModelForm):
  text = Textarea(required=False)

Django 返回:

__init__() got an unexpected keyword argument 'required'

来自评论。可能是:

class ThatForm(ModelForm):
    def __init__(self, *args, **kwargs):
        # first call parent's constructor
        super(ThatForm, self).__init__(*args, **kwargs)
        # there's a `fields` property now
        self.fields['desired_field_name'].required = False
