如果表达式为True，请更改django admin界面中字段的字体/颜色 [英] Change font/color for a field in django admin interface if expression is True

问题描述

在django admin界面中的更改列表视图中，是否可以在某些字段/行红色中标记表达式？

In change list view in django admin interface, is it possible to mark some fields/rows red in if they achieve a expression?

例如，如果有组与成员和容量的模型 或拥挤？

For example, if there is a model Group with members and capacity, how can I visualize when they are full or crowded?

推荐答案

和更改列表视图中显示的内容，可以使用 list_display 选项 ModelAdmin 。

For modifying how and what is displayed in change list view, one can use list_display option of ModelAdmin.

请注意， list_display 不是真正的数据库字段不能用于排序，所以需要给Django管理员一个关于实际用于排序的数据库字段的提示。

Mind you, columns given in list_display that are not real database fields can not be used for sorting, so one needs to give Django admin a hint about which database field to actually use for sorting.

一个doe这是通过将 admin_order_field 属性设置为用于在HTML中包装某些值的可调用的。

One does this by setting admin_order_field attribute to the callable used to wrap some value in HTML for example.

Django的示例多彩字段文档：

Example from Django docs for colorful fields:

class Person(models.Model):
    first_name = models.CharField(max_length=50)
    color_code = models.CharField(max_length=6)

    def colored_first_name(self):
        return '<span style="color: #%s;">%s</span>' % (
                             self.color_code, self.first_name)
    colored_first_name.allow_tags = True
    colored_first_name.admin_order_field = 'first_name'

class PersonAdmin(admin.ModelAdmin):
    list_display = ('first_name', 'colored_first_name')
