Django form is throwing error: "takes exactly 1 argument (0 given)"

I'm working on a basic event form created from a model, but I keep getting the following error message:

TypeError at /addlaundry/
addlaundry() takes exactly 1 argument (0 given)

I think it's because I'm not passing the argument through on views, but I can't find documented anywhere how to do this right, at least not written in a way I understand.

Here is my urls.py:

urlpatterns = patterns('',
    url('^addlaundry/$', 'beacon.laundry.views.addlaundry'),
}

And the views itself:

# Create your views here.

f开发者_运维百科rom schedule.views import EventForm

def addlaundry(request):
    if request.method == 'POST':
        form = EventForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/') #redirect after succesfully adding new delivery
    else:
     form = addlaundry()

    return render_to_response('newlaundry.html', {
        'form': form,
    })

Do I indeed have my views wrongly structured, or am I missing something else? If there's documentation I need to read up on, I want to I just haven't found it but feel like I'm missing something basic.

Thanks,

The problem is here:

form = addlaundry()

You're calling your view function addlaundry which takes 1 required argument (request), but you're not passing it any arguments.

Of course, that's not the right way to construct a form, anyway. You'll want to take a look at the examples given in the Django forms documentation to see how to create and use forms in Django.

Your view is called addlaundry, and it calls (presumably) something else called addlaundry. Rename one of them, or use the other addlaundry from inside its namespace.

This is your problem:

 form = addlaundry()

That's attempting to call the view itself! That's not what you want. You need to define a form class and call (instantiate) it here.

views.py :

from schedule.forms import EventForm

def addlaundry(request):
    if request.method == 'POST':
        form = EventForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    else:
        form = EventForm()

    return render_to_response('newlaundry.html', {
        'form': form,
    })

That means :

• using a forms.py file to define your forms
• initializing your form in a non post context (regular first page load), that will be passed to your template

Also, in urls.py your view should not be a string.

else:
 form = addlaundry()

Just as the exception says: The view function needs 1 argument, but you didn't supply any.
