Django管理员get_FOO_display [英] Django admin get_FOO_display

问题描述

我有这样的模型：

class M(models.Model):
    CHOICES = (('A', 'Accepted'), ('R', 'Rejected'))

    status = model.CharField(max_length=1, choices=CHOICES)

我通过这种方式在管理员中注册此模型：

I register this model in admin by this way:

class MAdmin(admin.ModelAdmin):
     list_display = ('get_status_display', )

但是我在状态列中看到字段名称​​ curried 。

But I see field name curried in status column.

如何为列指定普通名称​​ Status 还是我做错了什么？

How I can give normal name Status to column or I make something wrong?

我可以按此字段排序吗？

And can I sort by this field?

推荐答案

设置可调用的 get_status_display 的 short_description 属性，以控制列名。您无法按计算值排序（Django使用数据库进行排序），但是如果基础 status 字段给出了正确的排序顺序，请设置

Set the short_description attribute of your get_status_display callable to control the column name. You cannot sort by a calculated value (Django uses the database to do the sorting) but if your underlying status field gives the correct sort order, set the admin_order_field attribute to 'status'.

'状态'的admin_order_field 属性。 > list_display 给出了设置两个属性的示例：
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display

The docs for list_display give examples of setting both attributes: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display

由于它是一种自动创建的方法，因此稍微复杂一些-在类定义时该callable不可用。我认为，您可以在注册管理员之前进行设置，但我尚未进行测试：

Since it's an auto-created method, it's marginally more complicated - the callable isn't available at class definition time. I think you can set them before registering the admin, but I haven't tested that:

M.get_status_display.short_description = 'status'
M.get_status_display.admin_order_field = 'status'
admin.site.register(M, MAdmin)

如果这不起作用，请在恰好调用选择字段的 contribute_to_class 方法时追逐-created方法是弄清楚何时可以设置这些属性的一种方法。但是我可能会跳过它，并在管理类上贴上一个包装，我知道可以在其中设置属性。

If that doesn't work, chasing down when exactly the choice field's contribute_to_class method gets called to add the auto-created method is one way to figure out when you can set those attributes. But I'd probably just skip it and stick a wrapper on the admin class, where I know I can set the attributes.
