NameError when overriding __init__ of ModelForm

Question

I hope you can help me to figure out what's wrong with this code:

from django.forms import ModelForm
from models import Persona

class PersonaForm(ModelForm):

    class Meta:
        model = Persona
        exclude = ('cuenta',)

    def __init__(self, *args, **kwargs):
        cuenta = kwargs.pop('cuenta')
        super(PersonaForm, self).__init__(*args, **kwargs)
        self.fields['organizacion'].queryset = Organizacion.objects.filter(cuenta=cuenta)

I get the following error: name 'PersonaForm' is not defined

This is the whole traceback:

Exception Type: NameError at /
Exception Value: name 'PersonaForm' is not defined

I have looked for an answer around but has not found anything yet... Thanks!

Pretty sure you have an indentation error there. Looking at the traceback, the line with super is being executed when forms.py is being imported, which shouldn't usually happen if it's inside the __init__ method. So I would guess you have that line at the same level as the method definitions, and it is being executed when the form class is defined. Check you aren't mixing tabs and spaces anywhere, for example.
