django-admin 中的动态表单

发布于 2024-10-04 07:16:50 字数 586 浏览 4 评论 0原文

我想让管理添加表单动态化。我想根据相关对象中的设置添加一些表单字段。

我有这样的内容：

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 添加到管理添加表单和更改表单。然而，这种方法行不通。有没有办法在init中添加字段？它正在正常视图下工作。

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

I have something like this:

class ClassifiedsAdminForm(forms.ModelForm):


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

And in admin.py:

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

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.

我已经设法使用 type() 来做到这一点。

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

希望它能帮助某人。

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

Hope it will help someone.
