Re: Handling a reusable form in multiple views
Perfect. I actually realized soon after posting that option 1 would work well for this scenario, but option 2 would be a good future enhancement. Thanks for your help.

Option 1: Send your invalid form to a simple template that knows how to display the form and its errors. Option 2: Post your form via AJAX -- you should still implement Option 1 for people that have turned off Javascript -RD --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Handling a reusable form in multiple views
Rajesh,
Thanks for your response. If I post the form to a dedicated view that
works fine, but how do I handle validation properly in this approach.
Say the user enters invalid data, do I now need to redirect them back
to the original page and then display these errors? That seems like it
will be a headache as well. Note that this form is a reusable form
that gets displayed within most templates so it's just a little
section of the page. If I now enter invalid data and post the form,
it's going to post to a different view that will then see the form is
invalid and then what??
Thanks,
Delino

You could add your form to your request context using a context
processor under a key other than 'form' (so it doesn't clash with
forms defined by your other views). This way, your context processor
will make this form available globally. Secondly, instead of posting
this common form to '.', post it to a dedicated view that only knows
how to process this common form.

Handling a reusable form in multiple views
Hi,
I have a simple scenario using Django 0.96 and am looking for a
cleaner solution than what I currently have:
I want to include a simple submission form (a few simple fields) on
most pages of my site. I have the form action set to '.' so that
validation can be done in place and errors displayed to the user. I am
currently checking for the POST and either handling it or creating a
new form in each of these views and then passing the form to each of
my templates, e.g.
def example_page(request):
if request.method == 'POST':
form = SubmitMeForm(request.POST)
if form.is_valid():
# do your thing
return HttpResponseRedirect('/done/')
else:
form = SubmitMeForm()
variables = RequestContext(request, {
'submitMeForm': form,
})
return render_to_response('somePage.html', variables)
I have 2 issues with this:
1 - I have to include this code in each and every view that represents
a page that has this template. There has to be a simpler way of doing
it.
2 - What if one of these pages has another Django form in it? I now
have to handle the fact that the POST could have resulted from this
form OR the other one. How would I do that?
TIA
