を呼び出した際にエラーがジャンゴ:私のmodels.py内の問題でエラーが発生しました。ここメタクラス拠点
TypeError: Error when calling the metaclass bases metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
あるクラス
class Business(models.Model, forms.Form):
name = models.CharField(max_length=128)
tel_no = models.CharField(max_length=11)
address_ln1 = models.CharField(max_length=128)
address_ln2 = models.CharField(max_length=128)
city = models.CharField(max_length=64)
county = GBCountySelect()
postcode = GBPostcodeField()
website = models.URLField(max_length=128)
# Logging Info
slug = models.SlugField()
date_added = models.DateField(auto_now_add=True)
time_added = models.TimeField()
added_by_user = models.CharField(max_length=64)
last_edit_time = models.TimeField(auto_now=True)
last_edit_date = models.DateField(auto_now=True)
私は上のエラーを取得しています行:
name = models.CharField(max_length=128)
しかし、私は(考えて)これはこのことを意味します:
class Business(models.Model, forms.Form):
正確にはどういう意味かわかりません。私のモデルをモデルから継承するにはどうすればいいですか?モデルとフォーム。同じクラス内のフォームですか?クラスを作成するときに2つの値を渡すことはできませんか?もしそうなら、どのように?
ANOTHER EDIT
All my imports
from django.db import models
from django import forms
from django.contrib.localflavor import generic
from django.contrib.localflavor.gb.forms import GBPostcodeField, GBCountySelect
