эта ошибка не возникает, если я закомментирую admin.autodiscover()
, также я использовал ModelForm в django, так что это из-за ModelForm?Ниже приведен код ModelForm:
from django import forms
from catalog.models import Product
class ProductAdminForm(forms.ModelForm):
class Meta:
model=Product
def clean_price(self):
if self.cleaned_data['price']<=0:
raise forms.ValidationError('Price must be greater than zero')
return self.cleaned_data['price']
Так что, если кто-то поймет проблему, сообщите, пожалуйста.
