passing arguments to a dynamic form in django

Question

I have a Dynamic Form in forms. How can I pass an argument from my view when I instantiate my form?

Something like:

form = DynamicForm(\"some string

You can also achieve this by overriding the get_form_kwargs of the FormMixin, available in class based views.

class CustomDynamicFormView(FormView):  # inherit any view with formmixin...
      form_class = DynamicForm
      
      def get_form_kwargs(self):
          kwargs = super(CustomDynamicFormView, self).get_form_kwargs()
          kwargs['custom_variable'] = 'my custom variable'
          return kwargs

Then in your form

class DynamicForm(forms.Form):
    def __init__(self, *args, **kwargs):
        my_var = kwargs.pop('custom_variable') 
        # remove this b4 calling super otherwise it will complian
        super(DynamicForm, self).__init__(*args, **kwargs)
        # do what you want with my_var
