Issue
I am trying to make a search form for one of my classes. The model of the form is:
from django import forms
from django.forms import CharField, ModelMultipleChoiceField, ModelChoiceField
from books.models import Book, Author, Category
class SearchForm(forms.ModelForm):
authors = ModelMultipleChoiceField(queryset=Author.objects.all(),required=False)
category = ModelChoiceField (queryset=Category.objects.all(),required=False)
class Meta:
model = Book
fields = ["title"]
And the view I'm using is:
from django.shortcuts import render_to_response, redirect, get_object_or_404
from django.template import RequestContext
from books.models import Book,Author
from books.forms import BookForm, SearchForm
from users.models import User
def search_book(request):
if request.method == "POST":
form = SearchForm(request.POST)
if form.is_valid():
form = SearchForm(request.POST)
stitle = form.cleaned_data['title']
sauthor = form.cleaned_data['author']
scategory = form.cleaned_data['category']
else:
form = SearchForm()
return render_to_response("books/create.html", {
"form": form,
}, context_instance=RequestContext(request))
The form shows up fine, but when I submit it I get an error: 'SearchForm' object has no attribute 'cleaned_data'
I'm not sure what's going on, can someone help me out? Thanks!
Solution
For some reason, you're re-instantiating the form after you check is_valid()
. Forms only get a cleaned_data
attribute when is_valid()
has been called, and you haven't called it on this new, second instance.
Just get rid of the second form = SearchForm(request.POST)
and all should be well.
