以表格形式訪問管理模型實例

Question

class ProductAdmin(admin.ModelAdmin): 
    form = ProductAdminForm() 

class ProductAdminForm(forms.ModelForm): 
    def __init__(self, request, *args, **kwargs): 
     super(ProductAdminForm, self).__init__(*args, **kwargs) 
     self.fields['field1'] = forms.CharField(required=False) 
     self.fields['field2'] = forms.IntegerField() 

如何將產品實例從ProductAdmin傳遞到ProductAdminForm？我想根據產品實例提供不同的字段。

Answer 1

這樣的：

class ProductAdminForm(forms.ModelForm): 
    class Meta: 
     model = Product 

    def __init__(self, *args, **kwargs): 
     super(ProductAdminForm, self).__init__(*args, **kwargs) 

      product_instance = self.instance 
      if product_instance.id and product_instance.myField == "thatValue": 
       self.fields['field1'] = forms.CharField(required=False) 
       self.fields['field2'] = forms.IntegerField()
