Hi,
There are 2 errors in your code.
First, when you do a request to the page, it is a get (you go from another
page to this page). In this case the next parameter is there and you
receive it in the "else" part of your view function (because the request is
a get). So you have the next parameter as a get parameter in that case.
Second, when you submit the form, it is submitted via a post. In this case
the get parameters are filled out, but the POST part of the request is. So
you populate your form with the information sent via a POST, and you do
this here:
form = pollster.forms.LogInForm(request.POST)
So the GET part of the request is empty in this case, because the request
is a POST.
What you need to do is get the parameter from the request when you populate
the form and then send it to the template:
def log_in(request):
if request.method == "POST":
form = pollster.forms.LogInForm(request.POST)
if form.is_valid():
username = form.cleaned_data["username"].lower()
password = form.cleaned_data["password"]
next = form.cleaned_data('next')
reply = django.shortcuts.redirect(next)
user = AUTH(username = username,
password = password)
if user:
django.contrib.auth.login(request, user)
else:
reply = django.shortcuts.render(request,
"log_in.html",
{"form" : form})
else:
form = pollster.forms.LogInForm(initial_data={'next':
request.GET.get('next')})
reply = django.shortcuts.render(request,
"log_in.html",
{"form" : form})
return reply
So I have updated the code both for the get and post. The get populates the
initial data for the form (the next parameter). You of course need to add
the next field to your form code.
Then in the template you can add the following:
<div id = "log_in">
<form action = "." method = "post">
<input type="hidden" name="next"
value="{{form.next.value}}">
<p>Username:</p>
<p>{{form.username}}</p>
<p>Password:</p>
<p>{{form.password}}</p>
<p><input type = "submit" value = "Submit"/></p>
{% csrf_token %}
</form>
</div>
This way your form will include the posted next data and you can get the
next field from the login form.
Regards,
Andréas
