我希望你能帮助我弄清楚这段代码有什么问题：

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)

我收到以下错误：name 'PersonaForm' is not defined

这是整个追溯：

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

我一直在寻找答案，但还没有找到任何东西......谢谢！

很确定你有一个缩进错误。查看回溯，在super导入 forms.py 时正在执行该行，如果它在__init__方法内部，通常不会发生这种情况。所以我猜你有那行与方法定义在同一级别，并且在定义表单类时执行它。例如，检查您没有在任何地方混合制表符和空格。
