Тук е грешката
TypeError: Грешка при извикване на базите на метакласа конфликт на метаклас: метакласът на производен клас трябва да бъде (нестрог) подклас на метакласовете на всички негови бази
Въпросният клас в моя models.py
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)
Редът, на който получавам грешката:
name = models.CharField(max_length=128)
Но аз (мисля) това означава това:
class Business(models.Model, forms.Form):
Не съм сигурен какво точно означава, как мога да наследя моите модели от models.Model и forms.Form в рамките на един и същи клас? Не мога ли да предам две стойности, когато създавам моя клас? Ако да как?
