Using rstrip in form.cleaned_data [i] in Django
In my view.py, I have a piece of code like this:
def clean_post_data(form):
for i in form.cleaned_data:
form.cleaned_data[i] = form.cleaned_data[i].rstrip()
def add_product(request):
form = ProductForm(request.POST, request.FILES or None)
image = Image.objects.all()
action = "Add"
if request.POST:
if form.is_valid():
clean_post_data(form)
form.save()
action = "Added new product"
return render_to_response('cms/admin/action.html', {'action' : action},context_instance=RequestContext(request))
else:
action = "There was an error. Please go back and try again"
return render_to_response('cms/admin/action.html', {'action' : action}, context_instance=RequestContext(request))
return render_to_response('cms/admin/editproduct.html', {'form' : form, 'action' : action, 'image' : image}, context_instance=RequestContext(request))
But when I run this I get the following error 'list' object has no attribute 'rstrip'
. What am I doing wrong.
I originally had the loop for i in form.cleaned_data:
directly in the view (and not in another function) and it worked fine, but now when I try I get the same error as above. http://dpaste.com/92836/

clean_post_data
shouldn't be a standalone feature.
It must be a named method clean
. See Form and Field Validation .

Most likely, you have multiple elements in your form with the same name. When it dispatches, one of the items returned by cleaned_data is a list
If you want to skip (or do something special) in such cases, you need to check it out:
def clean_post_data (form):
for i in form.cleaned_data:
if ('__ iter__' in dir (form.cleaned_data [i])):
print "skip this element:" + str (form.cleaned_data [i])
else:
form.cleaned_data [i] = form.cleaned_data [i] .rstrip ()
