Django异步请求和后台管理实战

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.utils.translation import gettext
from .models import User
from .tasks import send_confirmation_email
 
class UserAdmin(BaseUserAdmin):
    ordering = ['id']
    list_display = ['email', 'username', 'is_staff']
 
    fieldsets = (
        (None, {'fields': ('email', 'password')}),
        (gettext('Personal info'), {'fields': ('username',)}),
        (gettext('Permissions'), {
            'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions'),
        }),
        (gettext('Important dates'), {'fields': ('last_login',)}),
    )
 
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'password1', 'password2', 'is_staff', 'is_superuser'),
        }),
    )
 
    search_fields = ('email',)
    list_filter = ('is_staff', 'is_superuser', 'is_active')
 
    def save_model(self, request, obj, form, change):
        if not obj.id:
            send_confirmation_email.delay(obj.email)
        super().save_model(request, obj, form, change)
 
admin.site.register(User, UserAdmin)

这段代码定义了一个UserAdmin类，继承自BaseUserAdmin，并对User模型的后台管理界面进行了定制。在保存模型时，如果User对象是新创建的（not obj.id），则会异步调用send_confirmation_email任务来发送确认邮件。这是一个很好的实践，展示了如何在Django中结合异步任务处理特定的业务逻辑。
