django-admin中的动态表单

Question

我想让admin add-form动态化.我想根据相关对象中的设置添加一些表单域.

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:

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admin add-form和change-form.但是,这种方式不起作用.有没有办法在init中添加字段？它在普通视图中工作.

Answer 1

我已经设法使用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

希望它会帮助某人.
