Change Django required form field to False

Question

I am trying to change the required of a form field to 'False' depending on the input of another field.

form:

class MyNewForm(forms.Form):

def __init__(self, *args, **kwargs):
    self.users = kwargs.pop('users', None)
    super(MyNewForm, self).__init__(*args, **kwargs)


    self.fields['name'] = forms.CharField(
        max_length=60,
        required=True,
        label="Name *:",
        widget=forms.TextInput(
            attrs={'class' : 'form-control', 'placeholder': 'Name'})
    )

def clean_this_other_field(self):

    # change required field
    name = self.fields['name']
    print name.required
    name.required=False
    print name.required

results of print:

True

False

So the field required is changing to 'False' but when the form page reloads it reverts back to 'True'

Any suggestions?

EDIT - Problem solved

For anyone landing on this with a similar issue:

def clean_remove(self):
    cleaned_data = super(MyNewForm, self).clean()
    remove = cleaned_data.get('remove', None)
    if remove:
        self.fields['name'].required=False

Remove is the first field in the form so adding this clean on the remove field resolves the issue.

Can you give more of your code when this problem appers?

If u use ModelForm you can do something like:

class YourForm(forms.ModelForm):    
    def __init__(self, *args, **kwargs):
        super(YourForm, self).__init__(*args, **kwargs)
        self.fields['name'].required = True

    class Meta:
        model = YouModel
        fields = (...)

U can add required using widget too:

email = forms.EmailField(
    max_length=100,
    required=True,
    widget=forms.TextInput(attrs={ 'required': 'true' }),
)
