这几天讲的是xadmin插件

就是把表单,数据内容封装到类里面,简化的增删改查步骤!

放上源代码:

app01/xadim.py

from django.contrib import admin

# Register your models here.

from Xadmin.service.Xadmin import site,ModelXadmin

print("app01 Xadmin")

from app01.models import *
from django.utils.safestring import  mark_safe

class BookConfig(ModelXadmin):
    def edit(self,obj=None,is_header=False):
        if is_header:
            return "操作"
        # 反向解析：url
        return mark_safe("<a href='%s/change/'>编辑</a>"%obj.pk)

    def delete(self,obj=None,is_header=False):

        if is_header:
            return "操作"

        return mark_safe("<a href=''>删除</a>")

    def check(self,obj=None,is_header=False):
        if is_header:
            return "选择"

        return mark_safe("<input type='checkbox'>")

    list_display=[check,"nid","title","publish",edit,delete]
    #list_display=["nid","title","publish"]

site.register(Book,BookConfig)

site.register(Publish)
site.register(Author)
site.register(AuthorDetail)

app02/xadmin.py

from Xadmin.service.Xadmin import site,ModelXadmin
