I'd like to have a field which is required conditionally based on setting a boolean value to True or False.
What should I return to set required =True if is_company is set to True?
class SignupFormExtra(SignupForm): is_company = fields.BooleanField(label=(u"Is company?"), required=False) NIP = forms.PLNIPField(label=(u'NIP'), required=False) def clean(self): if self.cleaned_data.get('is_company', True): return ...? else: pass

Let's try to use required via Django Web application we created, visit http://localhost:8000/ and try to input the value based on option or validation applied on the Field. Hit submit. Hence Field is accepting the form even without any data in the geeks_field. This makes required=False implemented successfully.
If yes try to disable this behavior, set the novalidate attribute on the form tag As <form action="{% url 'new_page' %}", method="POST" novalidate> in your html file.
CharField is a commonly-defined field used as an attribute to reference a text-based database column when defining Model classes with the Django ORM. The Django project has wonderful documentation for CharField and all of the other column fields.
Check the Chapter on Cleaning and validating fields that depend on each other in the documentation.
The example given in the documentation can be easily adapted to your scenario:
def clean(self): cleaned_data = super(SignupFormExtra, self).clean() is_company = cleaned_data.get("is_company") nip = cleaned_data.get("NIP") if is_company and not nip: raise forms.ValidationError("NIP is a required field.") return cleaned_data If you love us?
