을, 또한 나는 ModelForm 때문에 장고에서 ModelForm을 사용했기 때문에 그렇습니까? 다음은 ModelForm 코드입니다.

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'] 

따라서 어떤 사람이 문제를 이해한다면 알려주십시오.

은, 역 추적 붙여 태그 :

admin.site.register('Product', 'ProductAdmin') 

당신은 클래스의 객체가 아닌 문자열을 전달해야한다 :

Answer 1

문제는이 라인입니다. 이게 작동해야합니다 :

admin.site.register(Product, ProductAdmin)
