Hi Stackoverflow people,
In my clean function in forms.py, I would like to save automatically some information in a session variable. However, I do not seem to get access to the request variable.
All examples for handing over the request variable are based on function based views, but here I am using a class based view.
My forms.py:
from django import forms
from item.models import Item
class CreateItemForm(forms.ModelForm):
class Meta:
model = Item
fields = ('name', 'description')
def __init__(self, request, *args, **kwargs):
self.request = request
super(CreateItemForm, self).__init__(*args, **kwargs)
def clean(self):
cleaned_data = super(CreateItemForm, self).clean()
if cleaned_data.get("address"):
self.request.session['name'] = cleaned_data.get("name")
else:
raise forms.ValidationError(_('Oops, can\'t find location.'))
return self.cleaned_data
My views.py:
from django.views.generic.edit import FormView
from item.forms import CreateItemForm
class ItemCreate(FormView):
form_class = CreateItemForm
template_name = 'item/item_create.html'
success_url = 'http://www.google.com'
What is the best way to hand over the request
variable from the views.py to forms.py?
Thank you for your answer.
You can overwrite the FormMixin
's get_form_kwargs
method to add the request for to the form's init parameters:
class ItemCreate(FormView):
def get_form_kwargs(self):
kwargs = super(ItemCreate, self).get_form_kwargs()
kwargs.update({
'request' : self.request
})
return kwargs
