django-admin 中的动态表单

问题描述

我想让管理员添加表单动态化.我想根据相关对象中的设置添加一些表单域.

I want to make admin add-form dynamic. I want to add few formfields depending on setting in related object.

我有这样的事情:

class ClassifiedsAdminForm(forms.ModelForm):


  def __init__(self,*args, **kwargs):
     super(ClassifiedsAdminForm, self).__init__(*args, **kwargs)
     self.fields['testujemy'] = forms.CharField(label = "test")

在 admin.py 中:

And in admin.py:

class ClassifiedAdmin(admin.ModelAdmin):
     def get_form(self, request, obj=None, **kwargs):
         return ClassifiedsAdminForm

如您所见，我想将testujemy"CharField 添加到管理员添加表单和更改表单.然而，这种方式行不通.有没有办法在 init 中添加字段?它在正常视图下工作.

As you can see, I want to add "testujemy" CharField to admin add-form and change-form. However, this way doesnt work. Is there any way to add field in init? It is working in normal view.

推荐答案

我已经设法使用 type() 做到了.

I've managed to do it using type().

class ClassifiedAdmin(admin.ModelAdmin):

 def get_form(self, request, obj=None, **kwargs):

    adminform = ClassifiedsAdminForm()
    fields = adminform.getNewFields()

    form = type('ClassifiedsAdminForm', (forms.ModelForm,), fields)

    return form
