Django中实现站点管理

概述：

内容发布：负责添加、修改、删除内容，开发这些重复的功能是一件非常没有意义的事情，并且缺乏创造力。
Django会根据定义的模型类来自动生成管理模块

管理表中的数据:将要管理的表添加到应用目录下的admin.py文件中进行注册
from django.contrib import admin
# 引入要管理的模型类
from myApp.models import Student, Grade
# Register your models here.
admin.site.register(Student)
admin.site.register(Grade)
ModelAdmin类：是模型在Admin界面中的表现形式，通过定义ModelAdmin子类来定义模型在Admin界面的显示方式

from django.contrib import admin
# 引入要管理的模型类
from myApp.models import Student, Grade
# Register your models here.
@admin.register(Student)
class StudentAdmin(admin.ModelAdmin):
    def sex(self):
        if self.sex:
            return "男"
        else:
            return "女"
    sex.short_description = "性别"
    #列表页属性
    list_display = ["pk", "name", "age", sex, "grade", "contend", "isDelete"]
    list_filter = ["grade","age"]
    search_fields = ["name"]
    list_per_page = 10
    # 执行动作框的位置
    actions_on_top = False
    actions_on_bottom = True

    #添加、修改页属性
    # fields = ["name","age","sex","grade","contend","isDelete"]
    fieldsets = [
        ("base", {"fields":["name","age","sex"]}),
        ("more", {"fields": ["grade", "contend", "isDelete"]}),
    ]
# admin.site.register(Student, StudentAdmin)
class StudentInLine(admin.TabularInline):
    model = Student
    extra = 2
    
@admin.register(Grade)
class GradeAdmin(admin.ModelAdmin):
    inlines = [StudentInLine]
    list_display = ["pk", "name", "boyNum", "girlNum", "isDelete"]
    list_filter = ["name"]
    search_fields = ["name"]
    list_per_page = 10
    fields = ["name", "boyNum", "girlNum", "isDelete"]
# admin.site.register(Grade, GradeAdmin)
