Django TypeError：__ init __（）占用1个位置参数，但给出了2个

Question

我无法找到TypeError的解决方案： init （）需要1个位置参数但是2个被赋予

当我尝试在ubuntu concole中进行迁移时，会出现

TypeError。 错误：

  File "/home/wojciech/workspace/conference_room/conference_room/conference/forms.py", line 8, in NewRoomForm
    taken = forms.ChoiceField(TAKEN, label='Taken', widget=forms.Select)
TypeError: __init__() takes 1 positional argument but 2 were given

形式：

from django import forms
from .models import TAKEN


class NewRoomForm(forms.Form):
    name = forms.CharField(label='Name', max_length=32)
    number = forms.IntegerField(label='Room Number')
    taken = forms.ChoiceField(TAKEN, label='Taken', widget=forms.Select)
    description = forms.CharField(label='Description', widget=forms.Textarea)

模型：

TAKEN = (
    (True, 'Yes'),
    (False, 'No')
)


class Room(models.Model):
    name = models.CharField(max_length=32)
    number = models.IntegerField()
    taken = models.BooleanField(choices=TAKEN)
    description = models.CharField(max_length=128)

任何想法如何解决？

Answer 1

taken = forms.ChoiceField(choices=TAKEN, label='Taken', widget=forms.Select)

您需要将choices放在choices键
