FormView with get method doesn't show the form - django

Question

Thanks for read :/
When I remove the "get" from the view, the form works, but when I put it back, it doesn't render.
URL at the browser:
http://127.0.0.1:8000/activate?tpr=1140277&idpr=42
URLs:
url(r'^activate', Activation_vw.as_view(), name='activate')
VIEW:
class Activation_vw(FormView):
template_name = 'activate.html'
form_class = Activation_Form
success_url = '/dashboard/'
def get(self, request, *args, **kwargs):
tokenProspect_v = request.GET.get('tpr')
idProspect_v = request.GET.get('idpr')
USER = USERS.objects.filter(
id=idProspect_v).values('id', 'email', 'token')
if int(tokenProspect_v) != int(USER[0]['token']):
message = "Check the URL"
else:
message = USER[0]['email']
context = {'msg': message}
return self.render_to_response(context)
def form_valid(self, form):
# No code yet
return super(Activation, self).form_valid(form)
FORM:
class Activation_Form(forms.Form):
email = forms.EmailField()
password = forms.CharField(widget=forms.PasswordInput())
TEMPLATE:
Hello, {{ msg }}
<form action="" method="POST">
{%csrf_token%}
{{ form.as_p }}
<button type="submit">Activate</button>
</form>
All of them have the imports at the top of each file.
The get function works perfectly, I receive the tpr and the idpr but the form doesn't and because of that the form form_valid and the success_url doesn't work neither.
I suspect something is wrong in the return of my get, but can't figured out.

It is because your form is not being passed in the context:
context = {'msg': message}
return self.render_to_response(context)
You can use get_context_data to get the context and update it as you go:
context = self.get_context_data(msg=message)
return self.render_to_response(context)
This will call the get_context_data from the super class and include the form to the context along with adding the message.
