Django set field value after a form is initialized

Question

I am trying to set the field to a certain value after the form is initialized.

For example, I have the following class.

class CustomForm(forms.Form)         


        

Answer 1

in widget use 'value' attr. Example:

username = forms.CharField(
    required=False,
    widget=forms.TextInput(attrs={'readonly': True, 'value': 'CONSTANT_VALUE'}),
)
