I have a form and a formset on my template. The problem is that the formset is throwing validation error claiming that the management form is "missing or has been tampered with".
Here is my view
@login_required

user = UserProfile.objects.get(pk=request.session['_auth_user_id'])
blogz = list(blog.objects.filter(deleted='0'))
delblog = modelformset_factory(blog, exclude=('poster','date' ,'title','content'))
if request.user.is_staff== True:
staff = 1
else:
staff = 0
staffis = 1
if request.method == 'POST':
delblogformset = delblog(request.POST)
if delblogformset.is_valid():
delblogformset.save()
return HttpResponseRedirect('/home')
else:
delblogformset = delblog(queryset=blog.objects.filter( deleted='0'))
blogform = BlogForm(request.POST)
if blogform.is_valid():
blogform.save()
return HttpResponseRedirect('/home')
else:
blogform = BlogForm(initial = {'poster':user.id})
blogs= zip(blogz,delblogformset.forms)
paginator = Paginator(blogs, 10) # Show 25 contacts per page
# Make sure page request is an int. If not, deliver first page.
try:
page = int(request.GET.get('page', '1'))
except ValueError:
page = 1
# If page request (9999) is out of range, deliver last page of results.
try:
blogs = paginator.page(page)
except (EmptyPage, InvalidPage):
blogs = paginator.page(paginator.num_pages)
return render_to_response('home.html', {'user':user, 'blogform':blogform, 'staff': staff, 'staffis': staffis, 'blog':blogs, 'delblog':delblogformset}, context_instance = RequestContext( request ))

I have figured this out after running into the same error. In situations where you are using a form and a formset in the same view and template, the form should be processed before the formset to avoid raising a formset validation error.
of importance Also, if request.method == 'POST': SHOULD ONLY be used on the formset. So the above will appear as below in the view:
@login_required
def home(request):
user = UserProfile.objects.get(pk=request.session['_auth_user_id'])
blogz = list(blog.objects.filter(deleted='0'))
delblog = modelformset_factory(blog, exclude=('poster','date' ,'title','content'))
if request.user.is_staff== True:
staff = 1
else:
staff = 0
staffis = 1
blogform = BlogForm(request.POST)
if blogform.is_valid():
blogform.save()
return HttpResponseRedirect('/home')
else:
blogform = BlogForm(initial = {'poster':user.id})
if request.method == 'POST':
delblogformset = delblog(request.POST)
if delblogformset.is_valid():
delblogformset.save()
return HttpResponseRedirect('/home')
else:
delblogformset = delblog(queryset=blog.objects.filter( deleted='0'))
blogs= zip(blogz,delblogformset.forms)
paginator = Paginator(blogs, 10) # Show 25 contacts per page
# Make sure page request is an int. If not, deliver first page.
try:
page = int(request.GET.get('page', '1'))
except ValueError:
page = 1
# If page request (9999) is out of range, deliver last page of results.
try:
blogs = paginator.page(page)
except (EmptyPage, InvalidPage):
blogs = paginator.page(paginator.num_pages)
return render_to_response('home.html', {'user':user, 'blogform':blogform, 'staff': staff, 'staffis': staffis, 'blog':blogs, 'delblog':delblogformset}, context_instance = RequestContext( request ))
To avoid this error just wrap your formset POST bounding in a try/except block like so.
from django.core.exceptions import ValidationError # add this to your imports
if request.method == 'POST':
try:
delblogformset = delblog(request.POST)
except ValidationError:
delblogformset = None
if delblogformset and delblogformset.is_valid():
delblogformset.save()
return HttpResponseRedirect('/home')
The POST request from your blogform lacks the 'ManagementForm' hidden input that is required for your delblogformset and hence the validation error is thrown. We wrap in a try/except block because we know that if ValidationError has been raised than the POST was meant for your blogform and not delblogformset.
