How to redirect to previous page in Django after POST request

Question

I face a problem which I can't find a solution for. I have a button in navbar which is available on all pages and it is a button responsible for creating some content.

View that links with button:

def createadv(request):     uw = getuw(request.user.username)     if request.method =='POST':     form = AdverForm(request.POST, request.FILES)     if form.is_valid():         form.instance.user = request.user         form.save()         return HttpResponseRedirect('/', {'username': request.user.username, 'uw': uw})     args = {}     args.update(csrf(request))     args['username'] = request.user.username     args['form'] = AdverForm()     args['uw'] = uw     return  render_to_response('createadv.html', args) 

If you can see now I always redirect to main page '/' after creating content but I want to go back to the page with which I launched the creation of content.

You can add a next field to your form, and set it to request.path. After you processed your form you can redirect to the value of this path.

template.html

<form method="POST">     {% csrf_token %}     {{ form }}     <input type="hidden" name="next" value="{{ request.path }}">     <button type="submit">Let's Go</button> </form> 

views.py

next = request.POST.get('next', '/') return HttpResponseRedirect(next) 

This is roughly what django.contrib.auth does for the login form if I remember well.

If you pass through an intermediate page, you can pass the 'next' value via the querystring:

some_page.html

<a href="{% url 'your_form_view' %}?next={{ request.path|urlencode }}">Go to my form!</a> 

template.html

<form method="POST">     {% csrf_token %}     {{ form }}     <input type="hidden" name="next" value="{{ request.GET.next }}">     <button type="submit">Let's Go</button> </form>
