How do I fix a GET parameter error in django?

Question

The user selects a slot via a checkbox and also should enter a username, as shown in the template below:

<form action="/clubs/{{ club.id }}/vote/" method="post">
{% csrf_token %}
{% for slot in tom_open_slots %}
    <input type="checkbox" name="slot" id="slot{{ forloop.counter }}" value="{{ slot.id }}" />
    <label for="slot{{ forloop.counter }}">{{ slot.slot }} on Court {{slot.court}}</label><br />
{% endfor %}    
<input type="text" name="username" />
<input type="submit" value="Reserve" />

I then would like to display the username that was typed and time selected in the checkbox. I do this through the view and template below:

def vote(request, club_id):
    if 'username' in request.GET and request.GET['username'] and 'slot' in request.GET and request.GET['slot']:
        username = request.GET['username']
        slot = request.GET['slot']
        return render_to_response('reserve/templates/vote.html',{'username':username, 'slot':slot})
    else:
        return HttpResponse('Please enter a username and select a time.')


{{slot}}
{{username}}

When I go to vote.html though, I always get the error message though (Please enter a username and select a time). What is incorrect in the view that is not picking up the 2 GET parameters?

You are using POST request in your form:

<form action="/clubs/{{ club.id }}/vote/" method="post">

But in the view, you are checking the GET object which comes from GET request:

request.GET

Change your form method to method="get" to fix the problem.

Edit: read more on GET vs POST request here: When do you use POST and when do you use GET?

In Django, the HttpRequest object has three dictionaries which give you the request parameters:

request.GET gives you the query string parameters,
request.POST gives you the post data, and
request.REQUEST gives you both.

In your case, since the form is using the POST method, you should use either request.POST or request.REQUEST.
