权限

一 建表

　　最基础的权限表包括三张表：用户表，角色表，权限表。用户表与角色表，角色表与权限表均为多对多关系。

 

 图中app01是建项目时添加的app，rbac是新建项目之后添加的app，增强解耦性，可移到其他项目使用。

表关系：

from django.db import models

# Create your models here.


class User(models.Model):
    name = models.CharField(max_length=32,verbose_name="用户名")
    pwd = models.CharField(max_length=32,verbose_name="密码")
    roles = models.ManyToManyField(to="Role")

    def __str__(self):
        return self.name

    class Meta:
        verbose_name = "用户表"
        db_table = verbose_name
        verbose_name_plural = verbose_name

class Role(models.Model):
    name = models.CharField(max_length=32, verbose_name="角色")
    permissions = models.ManyToManyField(to="Permission")


    def __str__(self):
        return self.name

    class Meta:
        verbose_name = "角色表"
        db_table = verbose_name
        verbose_name_plural = verbose_name


class Permission(models.Model):
    title = models.CharField(max_length=32, verbose_name="权限")
    url = models.CharField(max_length=32, verbose_name="路径")

    def __str__(self):
        return self.title

    class Meta:
        verbose_name = "权限表"
        db_table = verbose_name
        verbose_name_plural = verbose_name

在rbac下的admin添加如下内容：通过访问127.0.0.1/admin，进行数据录入

from django.contrib import admin

# Register your models here.

from .models import *

admin.site.register(User)
admin.site.register(Role)
admin.site.register(Permission)
