help with "Key 'timeout' not found in <QueryDict: {}>"

[psychok7]

hi i have done a succefull query and i converted the results into links so i can make a post by clicking on the links to make a reservation.

my problem is, theres a variable timeout that i want to specify manually, but i get a "Key 'timeout' not found in <QueryDict: {}>"

i know i am supposed to pass that variable but i just dont know how.

my code is :

def reserve (request,user_id,park_id):

    #only works if the user exists in database

    u = get_object_or_404(User, pk=user_id)

    n = get_object_or_404(Notification, pk=park_id)

    p = get_object_or_404(Park, pk=1)

    r = Reservation(user=u ,notification=n, park=p, timeout=int(request.POST['timeout']),active=True,parked=False,reservation_date=datetime.now())

    r.save()

    return HttpResponse('Spot reserved')

html:

{% if parks %} <p>You searched for: <strong>{{ query }}</strong></p> <p>Found {{ parks|length }} park{{ parks|pluralize }}.</p> <ul> {% for park in parks %} <input type="text" name="timeout" value="60" id="timeout"> <li><a href="/accounts/{{ user.id }}/reserve/{{ park.id }}">{{ park.park_address }}</a></li> {% endfor %} </ul> {% endif %}

can someone help me?

Can we see what your "Reservation" model looks like? Specifically, that 'timeout' field?

timeout field is just an INTEGER.. just saying the amount of time the space will be reserved.

class Reservation(models.Model):
    
    user = models.ForeignKey(User)
    park = models.ForeignKey(Park)
    notification = models.ForeignKey(Notification)

    timeout = models.IntegerField()
    active = models.BooleanField()
    parked = models.BooleanField()
    reservation_date = models.DateTimeField('date reserved')

ahh, okay. Let’s try another approach to see if you can nail down that error. I’m not sure why it’s not working.

 

def reserve(request, park_id):

   

    # Get the User

    # This is different than the method you’re using

    # but I think it may be what you want.

 

    user = self.request.user

 

    # Grab that Notification and Park

    # In your method, you were throwing a 404 error. I’m

    # not sure if that’s what you’re actually after (page not found)

    # or if you’d rather give a server error because the user attempted

    # to use a notification or park that didn’t exist.

 

    # Also, I’m a bit confused by the variable names, haha. I’d think the Park

    # object would take the park_id and the Notification object would use

    # something else.

 

    notification = Notification.objects.get(pk = park_id)

    park = Park.objects.get(pk = 1)

 

    # This will check to see if that POST Variable is available.

    if ’timeout’ is in request.POST:

 

        # Grab the Timeout Variable

        timeout = int(request.POST[’timeout’])

 

        # Let’s build the Reservation object piece by piece to see what the problem is.

        reservation = Reservation.objects.create()

        reservation.user = user

        # ....

        reservation.notification = notification

        reservation.timeout = timeout

        # ...

        reservation.save()

 

        return HttpResponse(...)

 

    # This is the error case where the timeout wasn’t POST'ed.

    else:

        raise Exception(”The timeout variable wasn’t posted.”)

 

This time, you should see exactly where that error is popping up. Also, ModelForm + CreateView would be a great an easy combination for this exact situation.

       

Good luck!

No, you haven't. When you click you'll still send very much standard GET
request to server. You can and should verify that by using some
debugging console.

If above is your true HTML and nothing removed you're just creating list
of standard links.

If you want to pass additional parameters there is few ways to achieve it:

a) You can modify your sent url by javascript and add timeout manually
to get query parameters.

b) You transform your links to selectable list/dropdown and create real
HTML form to send post with real submit button.

c) Hybrid of a and b. I won't go into details since it would be just a mess.

- Well planned is half done and a half done has been sufficient before...

[Kurtis Mullins]

Jani is right, I didn't take a close look at that HTML. Using this (without any Javascript), you're not submitting a form with method="post" so you won't actually have any of that request.POST data available that you're looking for.
