Django, rendering a view from another view (call a specific URL)

Question

I have a little form:

<form action="#" method="post">
    {% csrf_token %}
    <label>Company Number:</label>
    <input type="text" name="company" placeholder=""/><br>
    <input type="submit" id="register value=" OK" />
</form>

Which is mapped like this:

url(r'^userfilt/insertForm/$', views.insertForm, name='insertForm'),

Now after submitting this form, I want to get back to the main view:

url(r'^userfilt/$', views.userfilt, name='userfilt')

URL mapping file:

app_name = 'SSO_Management_POC'
urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^user/$', views.user, name='user'),
    url(r'^userfilt/$', views.userfilt, name='userfilt'),
    url(r'^userfilt/insertForm/$', views.insertForm, name='insertForm'),
    #url(r'^updateForm/$', views.updateForm, name='updateForm'),
    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),
    url(r'^(?P<pk>[0-9]+)/results/$', views.ResultsView.as_view(), name='results'),
    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),
]

The main view is like this (but I don't think this code is related to the problem..):

def userfilt(request):
    if request.GET.get('create'):
        return HttpResponseRedirect('insertForm')

    if request.GET.get('update'):
        print request.GET.get('pk')
        return render(request, 'SSO_Management_POC/updateForm.html')

    if request.method == 'POST':
        form = UserForm(request.POST)
        val = request.POST.get('my_textarea')
        return render(request, 'SSO_Management_POC/userfilt.html',
                      {'top_user': TopUser.objects.filter(user_name__regex=val)})
    else:
        print '4'
        return render(request, 'SSO_Management_POC/userfilt.html')

Now the call that is killing me happens when N submit the form, N just wanna get back to the main page calling it with a POST, like a always did!

return render(request, "SSO_Management_POC/userfilt.html")

I do it like this, but the problem is that the URL has not been reset.. and results in this,

http://127.0.0.1:8000/SSO_Management_POC/userfilt/insertForm/#

Resulting in every operation I make on that page not work because it's not mapped anymore

I mean, it should be:

• http://127.0.0.1:8000/SSO_Management_POC/userfilt/

but instead it is

• http://127.0.0.1:8000/SSO_Management_POC/userfilt/insertForm/#)

To try to explain my issue better..

I go to the main page (http://127.0.0.1:8000/SSO_Management_POC/userfilt/)

"GET /SSO_Management_POC/userfilt/ HTTP/1.1" 200 2648

Then I click on the create User to call the form, it brings me to: (http://127.0.0.1:8000/SSO_Management_POC/userfilt/insertForm/)

"GET /SSO_Management_POC/userfilt/insertForm/ HTTP/1.1" 200 1549

Than I submit the form and I would like to get back to the main page, and here comes the thing I don't understand: it bring me here

http://127.0.0.1:8000/SSO_Management_POC/userfilt/insertForm/#

But I want to go here

http://127.0.0.1:8000/SSO_Management_POC/userfilt

This is again the code:

return render(request, "SSO_Management_POC/userfilt.html")

This is the call made:

"POST /SSO_Management_POC/userfilt/insertForm/ HTTP/1.1" 200 2648

I tried with render, with HttpResponseRedirect and so on... But always it happened the URL I'm calling with the previous one, I want it to be reset, I want it to be ../ !!!

The only thing that work for me is:

return redirect("../")

but

1. this is dirty
2. this does not permit to make a POST call!

Thanks to Daniel, I fixed it like this:

return redirect('/SSO_Management_POC/userfilt')

But it still give me same issue with:

return render(request,'/SSO_Management_POC/userfilt')

Getting me to http://127.0.0.1:8000/SSO_Management_POC/userfilt/insertForm/

Answer 1

You should always redirect, not render, after a successful post. Doing return redirect(url) is the correct thing to do, and it's not clear why you're not happy with this.

Note that redirect can accept the name of a URL pattern, so you could do return redirect('userfilt') which will take you to the correct place.

Does the following code solve your problem?

In your template:

<form action="{% url 'userfilt' %}" method="post">
