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

问题描述

在django管理界面的更改列表视图中，如果某些字段/行实现了表达式，是否可以将它们标记为红色?

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，如果有一个模型 Group 具有 members 和 capacity，我如何可视化它们full 还是 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

这是一个老问题，但我会从 Django 1.10 的文档中添加一个示例，因为 allow_tags自 Django 1.9 起，已接受的答案中使用的属性已被弃用，建议使用 format_html 代替:

This is an old question but I'll add an example from docs for Django 1.10 because allow_tags attribute used in the accepted answer is deprecated since Django 1.9 and it is recommended to use format_html instead:

from django.db import models
from django.contrib import admin
from django.utils.html import format_html

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

    def colored_name(self):
        return format_html(
            '<span style="color: #{};">{} {}</span>',
            self.color_code,
            self.first_name,
            self.last_name,
        )

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