I\'ve a settings page where users can select if they want to receive a newsletter or not.

I want a checkbox for this, and I want that Django select it if \'newsletter\'

    models.py:

    class Settings(models.Model):
        receive_newsletter = models.BooleanField()
        # ...
    

    forms.py:

    class SettingsForm(forms.ModelForm):
        receive_newsletter = forms.BooleanField()
    
        class Meta:
            model = Settings
    

    And if you want to automatically set receive_newsletter to True according to some criteria in your application, you account for that in the forms __init__:

    class SettingsForm(forms.ModelForm):
    
        receive_newsletter = forms.BooleanField()
    
        def __init__(self):
            if check_something():
                self.fields['receive_newsletter'].initial  = True
    
        class Meta:
            model = Settings
    

    The boolean form field uses a CheckboxInput widget by default.

    class PlanYourHouseForm(forms.ModelForm):
    
        class Meta:
            model = PlanYourHouse
            exclude = ['is_deleted'] 
            widgets = {
                'is_anything_required' : CheckboxInput(attrs={'class': 'required checkbox form-control'}),   
            }

    You can just add required=False on your forms.BooleanField() args.

    You use a CheckBoxInput widget on your form:

    https://docs.djangoproject.com/en/dev/ref/forms/widgets/#django.forms.CheckboxInput

    If you're directly using ModelForms, you just want to use a BooleanField in your model.
