'str' object has no attribute 'get' (Django)

Question

Ahoy Mateys!

got a simple model with a simpel form here:

class Hardware(models.Model):
type_name = models.CharField(max_length=60)

def __unicode__(self):
    return self.type_name



class HardwareForm(ModelForm):
    class Meta:
        model = Hardware
        fields = ['type_name']

and this is used by my simple views function:

def createHardware(request):
if request.method == 'POST':
    form = HardwareForm('request.POST')
    if form.is_valid():
        new_hardware = form.save()


        return render_to_response('administration/overview.html')
else:
    form = HardwareForm()

    return render_to_response('administration/create_hardware.html', {
                    'form': form, }, context_instance = RequestContext(request))

this is the Traceback:

  207.         return data.get(name, None)

Exception Type: AttributeError at /ticket/createHardware/
Exception Value: 'str' object has no attribute 'get'

so i got several forms with much more data in it, and there is no problem to pass an empty form to the html page, fill it out and POST them back to the function to get the data in the form. run is_valid() and pass the data to a new instance of the model (to add some more data to it)

why do i get here this error?

Answer 1

You need to be passing in a dictionary to your HardwareForm, not a string.

Change in your views.py

form = HardwareForm('request.POST')

to:

form = HardwareForm(request.POST)
