[FIXED] MultiDict Error Django

Issue

Im using Django and trying to get a response by using AJAX. I have two forms, the first one works just fine. Though I use the same logic in my second form handling it does not work well.

models.py

class AskMe(models.Model):
    name = models.CharField(max_length=1000)

views.py

def AskMeQ(request):
    if request.method == POST:
        name = request.POST['name']

        AskMe.objects.create(name=name)

urls.py

url('r^askmeQ/$', views.AskMeQ)

ajax logic

$('.former').on('submit', '.ajaxform', function(event) {
    event.preventDefault();
    $.ajax({
        url: '/askmeQ/',
        type: 'POST',
        data: {name: $('#name').val(),
                csrfmiddlewaretoken: csrftoken
        }
    })
    .done(function() {
        console.log("success");
        $('.formset').slideToggle(400)
        });
    })
    .fail(function() {
        console.log("error");
    })
    .always(function() {
        console.log("complete");
    });
});

ERROR

Traceback:

During handling of the above exception ('name'), another exception occurred:

Exception Type: MultiValueDictKeyError at /askmeQ/
Exception Value: 'name'

The logic I use above used to work in all the previous forms, but here it throws me an error.
The SQLite3 table has been created as projectname_model.name.

How can I correct this?

Solution

It seems that the name was not posted with the request. Due to which, you name = request.POST['name'] will throw an error since the key won't be part of the POST dict.

To correct this, alter your code to:

def AskMeQ(request):
    if request.method == POST:
        name = request.POST.get('name')
        if name:
            AskMe.objects.create(name=name)
        # else:
        #     error condition handling
