django models 字体颜色

def colored_name(self):
    if self.状态 == ‘Y‘:
        color_code = ‘green‘
    else:
        color_code = ‘red‘
    return format_html(
        ‘<span style="color:{};">{}</span>‘,
        color_code,
        self.状态
    )

但如果你给这个方法添加一个boolean的属性并赋值为True，它将显示为on/off的图标，如下图：

from django.db import models
from django.contrib import admin
class Person(models.Model):
    first_name = models.CharField(max_length=50)
    birthday = models.DateField()

    def born_in_fifties(self):
        return self.birthday.strftime(‘%Y‘)[:3] == ‘195‘
    # 关键在这里
    born_in_fifties.boolean = True

class PersonAdmin(admin.ModelAdmin):
    # 官方文档这里有错，将‘name‘改为‘first_name‘ 
    list_display = (‘first_name‘, ‘born_in_fifties‘)
