It's not the POST button that should redirect, but the view.

If not differently specified, the form (the HTML form tag) POSTs to the same URL. If the form is on /contact/, it POSTs on /contact/ (with or without slash, it's the same).

It's in the view that you should redirect to thanks. From the doc:

def contact(request):
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...
            return HttpResponseRedirect('/thanks/') # Redirect after POST
    else:
        form = ContactForm() # An unbound form

    return render_to_response('contact.html', {
        'form': form,
    })

Change /thanks/ to /contact/thanks/ and you're done.

Solution 2

All of the responses are correct but a better approach is to give names to your URLs in urls.py and hint to them in views with reverse function (instead of hard coding URL in views).

urls.py:

(r'^contact/$', contact, name='contact'),
(r'^contact/thanks/$', contact_thanks, name='thanks'),

And hint them in views.py like this:

from django.urls import reverse

return HttpResponseRedirect(reverse('app_name:thanks'))

This is better for future approach and follow the DRY principle of Django.

Solution 3

Just try this. It worked for me.

return HttpResponseRedirect('thanks/')

Note:- Remove the forward slash before

I have created a basic contact form, and when the user submits information, it should redirect to the "Thank You" page.

views.py:
```
def contact(request):
    # if no errors...
    return HttpResponseRedirect('/thanks/')
```
urls.py:
```
(r'^contact/$', contact),
(r'^contact/thanks/$', contact_thanks),
```
Both pages work at the hard-coded URL. However, when I submit the form on /contact/ it redirects to /contact (no ending slash), which is a nonexistent page (either a 404 or an error page telling me I need a slash).

What is the reason it not correctly redirecting, and how can I fix this?

UPDATE: the return HttpResponseRedirect('/contact/thanks/') is what I now have, but the problem is that the submit button (using POST) does not redirect to the URL -- it doesn't redirect at all.

Isn't the setting True by default? - It is.

How can we send the data using HttpResponseRedirect?

@MegaBytes: data? what do you mean?

The data means any information, from one view to another view. e.g. Can We do this way, data = {'xyz': 'abcd', 'ddd':'yyyy'} return HttpResponseRedirect('/contact/thanks/', data). I am new in django, and I reading doc also but I am not getting a way to do it. render` is one way but I dont want to go to any browser page. just transfer data between views.

I know this is an old comment, but yes you can send data via the querystring along the lines of this: redirect_url = '{redirect_url}?{querystring}'.format( redirect_url=reverse("YOUR_VIEW_NAME", kwargs={'named_keywork': obj.pk}), querystring=urlencode( {'xyz': 'abcd', 'ddd': 'yyyy'}, doseq=True ) )

Reverse is great for smaller applications, but can lead to high overhead when working with applications that have large numbers of routes. For example at my company we have a URLs.py file with hundreds of routes, and sub applications that have even more. I'd say all total we have 400-500 or more? Just be mindful of that lookup hit.

@commadelimited If there are a lot of urls, then reverse is overhead. I think hardcoding oif url will cause a bigger overhead for developer later if we change the url

You'll need this import: from django.urls import reverse

we can also use reverse function with django 2.1 (not sure about older versions). Example: HttpResponseRedirect(reverse('view_name')), where view name is specified in urls.py

what happen if user will not wait for message and go to the another page. still message display with redirect to contact page or getting error?
