    bata         


        

Answer 1

Add 'checked' attribute to your Checkbox Input field widget in presentationForm. So that your code becomes :

class presentationForm(forms.ModelForm):

class Meta : 
    model = Sub
    widgets = {
    'batata': forms.CheckboxInput(attrs={'id':'batata', 'checked' : ''}),
}
def __init__(self, *args, **kwargs):
    self.valbata = kwargs.pop("arg_bata")
    super(presentationForm, self).__init__(*args, **kwargs)
    self.fields['batata'].initial = True
