python - Django 类型错误 : __init__() takes 1 positional argument but 2 were given

Question

我找不到 TypeError 的解决方案:init() takes 1 positional argument but 2 were given

当我尝试在 ubuntu concole 中进行迁移时出现 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

表格:

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)

有什么解决办法吗？

Answer 1

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

你需要把choices放在choices键
