将动态字段添加到Django管理模型表单 [英] Add dynamic field to django admin model form

问题描述

我需要将带有指向我网站上的模型视图链接的字段添加到django管理员视图。
当我将字段名称添加到 list_display 并定义呈现此URL的方法时：

I need to add the field with link to the model view on my site to the django admin view. When I add field name to the list_display and define method for rendering this url:

class SetAdmin(admin.ModelAdmin):
    list_display = ['many other fields', 'show_set_url']

    def show_set_url(self, obj):
            return '<a href="#">Set</a>' # render depends on other fields

它在django admin的集合列表中显示，但不以模型形式显示。
如何解决此问题并在django admin中添加到Sets Form的链接？

It shows in Sets list in django admin, but not in model form. How can I fix this and add link to the Sets Form in django admin?

我也尝试为此模型创建自定义表单：

I've tried also to create custom form for this model:

from core.models import Set
from django import forms

class SetAdminForm(forms.Form):
    class Meta:
        model = Set

    def __init__(self, *args, **kwargs):
        super(SetAdminForm, self).__init__(*args, **kwargs)
        self.fields['foo'] = forms.IntegerField(label=u"Link")

但是现在有可见的形式。

But there is now visible effect in form.

推荐答案

您可以完成自己的工作请通过重写 ModelAdmin 进行尝试，但您还需要重写 ModelAdmin.get_fieldsets 。 此答案可能会帮助您。链接中的OP也有类似的问题。

You can accomplish what you're trying by overriding ModelAdmin but you also need to override ModelAdmin.get_fieldsets. This answer might help you out. The OP in the link has a similar problem as well.

编辑：：如果您不希望使用可编辑字段，可以尝试覆盖 ModelAdmin.get_readonly_fields 。还要在此处中进行检查，以覆盖更多要覆盖的属性。

If you don't want an editable field you can try overriding ModelAdmin.get_readonly_fields. Also check here for more attributes to override.
