Django admin 真是一個強大的東西,輕輕鬆鬆就能搭好一個網站的後臺,大部分的功能都能知足。它也自帶了操做後的消息提醒。具體能夠查看文檔Admin actions。文檔中有很是簡單的給用戶發送消息的方法,即:python
self.message_user(request, message)
可是這樣的消息都是「操做成功」的消息,消息前面帶的是一個綠色勾的圖標。而不少時候須要對錯誤的操做和未成功的操做給出提示,這也的提示消息顯然不行。django
這也很簡單,Django中帶有messages模塊,能夠作出各類消息定製。Django真是一個大而全的框架。app
直接上代碼:框架
from django.contrib import admin from models import Category, Group, Topic, Report, Applicant from django.contrib import messages class ApplicantAdmin(admin.ModelAdmin): list_display = ('applicant', 'group', 'reason', 'join_type', 'status') list_filter = ('group', 'join_type', 'status') actions = ['pass_apply', 'reject_apply'] def pass_apply(self, request, queryset): """ 經過申請 @fanlintao """ can_treat = True for q in queryset: if q.status != 'processing': can_treat = False continue if can_treat: for q in queryset: if q.join_type == "manager": q.group.manager.add(q.applicant) # 將申請人加進小組管理員 q.status = "pass" q.save() elif q.join_type == "member": q.group.member.add(q.applicant) # 將申請人加進組員 q.status = "pass" q.save() msg = u"已經經過全部申請" self.message_user(request, msg) else: msg = u"只有狀態爲processing的記錄能操做,請確認!" messages.add_message(request, messages.ERROR, msg) pass_apply.short_description = u"經過申請" def reject_apply(self, request, queryset): """ 拒絕申請 @fanlintao """ can_treat = True for q in queryset: if q.status != 'processing': can_treat = False continue if can_treat: queryset.update(status="reject") msg = u"已經駁回全部申請" self.message_user(request, msg) else: msg = u"只有狀態爲processing的記錄能操做,請確認!" messages.add_message(request, messages.ERROR, msg) reject_apply.short_description = u"拒絕申請" admin.site.register(Applicant, ApplicantAdmin)
使用定製的add_message
方法就能完成一個錯誤的消息提醒啦。雖然仍是比較簡陋,只是消息前換了個紅色的圖標,但對於後臺也夠用啦。網站
PS:看來還要好好看看Django的messages模塊了。code
