body: <p>I have the following code to set the initial value for a DateField and CharField. CharField's initial value got set properly, but the DateField's initial value is still blank. </p>
  
  <pre><code>class MyForm(forms.ModelForm):
      dummy = fiscal_year_end = forms.CharField()
      date = forms.DateField()
  
      def __init__(self, *args, **kwargs):
  
          super(MyForm, self).__init__(*args, **kwargs)
          today = datetime.date.today()
          new_date = datetime.date(year=today.year-1, month=today.month, day=today.day)
          self.fields["date"].initial = new_date
          self.fields["dummy"].initial = 'abc'
