[英]How to use new Django 1.2 readonly_fields in ModelForm
I'm trying to use the new readonly_fields in a ModelForm. 我正在尝试在ModelForm中使用新的readonly_fields。
class TrainingAddForm(forms.ModelForm):
class Meta:
model = TrainingTasks
readonly_fields = ('trainee_signed','trainee_signed_date')
But this does not work. 但这是行不通的。 Am I missing something or is this not possible? 我错过了什么吗?
As per the documentation , this is a member of admin.ModelAdmin
, not forms.ModelForm
. 根据文档 ,这是admin.ModelAdmin
的成员,而不是forms.ModelForm
的成员。 Your admin form needs to inherit from admin.ModelAdmin
in order for you to have access to the readonly_fields
option. 您的管理表单需要从admin.ModelAdmin
继承,以便您可以访问readonly_fields
选项。
Edit : I mis-read the original question, I thought you were trying to use the field within Django's supplied admin app. 编辑 :我误读了原始问题,我以为您正在尝试使用Django提供的管理应用程序中的字段。 However, as seen in my initial response, this option is only available for classes that inherit from admin.ModelAdmin
— you will not be able to use it via forms.ModelForm
. 但是,从我的初始响应中可以看出,此选项仅适用于从admin.ModelAdmin
继承的类-您将无法通过forms.ModelForm
使用它。
有关以表单的形式进行操作,请参见在Django表单中,如何将字段设置为只读(或禁用)以便无法对其进行编辑?
