day13 订单管理项目开发

在这里插入图片描述

1.表结构设计

1.1 abstract类

from django.db import models


class ActiveBaseModel(models.Model):
    active = models.SmallIntegerField(verbose_name="状态", default=1, choices=((1, "激活"), (0, "删除"),))

    class Meta:
        abstract = True


class Administrator(ActiveBaseModel):
    """ 管理员表 """
    username = models.CharField(verbose_name="用户名", max_length=32, db_index=True)
    password = models.CharField(verbose_name="密码", max_length=64)
    mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True)
    create_date = models.DateTimeField(verbose_name="创建日期", auto_now_add=True)

1.2 自增和主键

默认:DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

class Administrator(models.Model):
    """ 管理员表 """
    uid = models.AutoField(verbose_name="自增", primary_key=True)
    
    username = models.CharField(verbose_name="用户名", max_length=32, db_index=True)
    password = models.CharField(verbose_name="密码", max_length=64)
    mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True)
    create_date = models.DateTimeField(verbose_name="创建日期", auto_now_add=True)

1.3 逻辑删除

class Administrator(ActiveBaseModel):
    """ 管理员表 """
    username = models.CharField(verbose_name="用户名", max_length=32, db_index=True)
    password = models.CharField(verbose_name="密码", max_length=64)
    mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True)
    create_date = models.DateTimeField(verbose_name="创建日期", auto_now_add=True)
    active = models.SmallIntegerField(verbose_name="状态", default=1, choices=((1, "激活"), (0, "删除"),))

1.4 数据库连接

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'day06',  # 数据库名字
        'USER': 'root',
        'PASSWORD': 'root123',
        'HOST': '127.0.0.1',
        'PORT': 3307,
    }
}

1.5 表结构参考

from django.db import models


class ActiveBaseModel(models.Model):
    active = models.SmallIntegerField(verbose_name="状态", default=1, choices=((1, "激活"), (0, "删除"),))

    class Meta:
        abstract = True


class Administrator(ActiveBaseModel):
    """ 管理员表 """
    username = models.CharField(verbose_name="用户名", max_length=32, db_index=True)
    password = models.CharField(verbose_name="密码", max_length=64)
    mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True)
    create_date = models.DateTimeField(verbose_name="创建日期", auto_now_add=True)


class Level(ActiveBaseModel):
    """ 级别表 """
    title = models.CharField(verbose_name="标题", max_length=32)
    percent = models.IntegerField(verbose_name="折扣", help_text="填入0-100整数表示百分比,例如:90,表示90%")

    def __str__(self):
        return self.title


class Customer(ActiveBaseModel):
    """ 客户表 """
    username = models.CharField(verbose_name="用户名", max_length=32, db_index=True)
    password = models.CharField(verbose_name="密码", max_length=64)
    mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True)
    # mobile = models.CharField(verbose_name="手机号", max_length=11, db_index=True, validators=[RegexValidator(r'^\d{11}$', '手机号格式错误'), ], )
    balance = models.DecimalField(verbose_name="账户余额", default=0, max_digits=10, decimal_places=2)
    level = models.ForeignKey(verbose_name="级别", to="Level", on_delete=models.CASCADE)
    # level = models.ForeignKey(verbose_name="级别", to="Level", on_delete=models.CASCADE, limit_choices_to={'active': 1})
    create_date = models.DateTimeField(verbose_name="创建日期", auto_now_add=True)
    creator = models.ForeignKey(verbose_name="创建者", to="Administrator", on_delete=models.CASCADE)


class PricePolicy(models.Model):
    """ 价格策略(原价,后续可以根据用级别不同做不同折扣)
    1  1000 10
    2  2000 18
    """
    count = models.IntegerField(verbose_name="数量")
    price = models.DecimalField(verbose_name="价格", default=0, max_digits=10, decimal_places=2)


class Order(ActiveBaseModel):
    """ 订单表 """
    status_choices = (
        (1, "待执行"),
        (2, "正在执行"),
        (3, "已完成"),
        (4, "失败"),
        (5, "已撤单"),
    )
    status = models.SmallIntegerField(verbose_name="状态", choices=status_choices, default=1)

    # 202211022123123123
    oid = models.CharField(verbose_name="订单号", max_length=64, unique=True)
    url = models.URLField(verbose_name="视频地址", db_index=True)
    count = models.IntegerField(verbose_name="数量")

    price = models.DecimalField(verbose_name="价格", default=0, max_digits=10, decimal_places=2)
    real_price = models.DecimalField(verbose_name="实际价格", default=0, max_digits=10, decimal_places=2)

    old_view_count = models.CharField(verbose_name="原播放量", max_length=32, default="0")

    create_datetime = models.DateTimeField(verbose_name="创建时间", auto_now_add=True)
    customer = models.ForeignKey(verbose_name="客户", to="Customer", on_delete=models.CASCADE)
    memo = models.TextField(verbose_name="备注", null=True, blank=True)


class TransactionRecord(ActiveBaseModel):
    """ 交易记录 """
    charge_type_class_mapping = {
        1: "success",
        2: "danger",
        3: "default",
        4: "info",
        5: "primary",
    }
    charge_type_choices = ((1, "充值"), (2, "扣款"), (3, "创建订单"), (4, "删除订单"), (5, "撤单"),)
    charge_type = models.SmallIntegerField(verbose_name="类型", choices=charge_type_choices)

    customer = models.ForeignKey(verbose_name="客户", to="Customer", on_delete=models.CASCADE)
    amount = models.DecimalField(verbose_name="金额", default=0, max_digits=10, decimal_places=2)

    creator = models.ForeignKey(verbose_name="管理员", to="Administrator", on_delete=models.CASCADE, null=True, blank=True)

    order_oid = models.CharField(verbose_name="订单号", max_length=64, null=True, blank=True, db_index=True)
    create_datetime = models.DateTimeField(verbose_name="交易时间", auto_now_add=True)
    memo = models.TextField(verbose_name="备注", null=True, blank=True)

2.用户认证相关

两种登录方式:

  • 用户名 + 密码 登录
  • 手机号 + 短信 登录

当用户登录成功后,将用户信息保存至Session【数据库 or 缓存】,不同类型用户登录 显示不同的菜单项。

2.1 发送短信

  • 腾讯云短信
  • 云通信短信
  • 互亿无线106短信

2.2 缓存和Session

pip install django-redis
CACHES = {
    "default": {
        "BACKEND": "django_redis.cache.RedisCache",
        "LOCATION": "redis://127.0.0.1:6379",
        "OPTIONS": {
            "CLIENT_CLASS": "django_redis.client.DefaultClient",
            "CONNECTION_POOL_KWARGS": {"max_connections": 100}
            "PASSWORD": "qwe123",
            # 'MAX_ENTRIES': 300,  # 最大缓存个数(默认300)
            # 'CULL_FREQUENCY': 3,  # 缓存到达最大个数之后,剔除缓存个数的比例,即:1/CULL_FREQUENCY(默认3)
        }
    }
}
############
# SESSIONS #
############
# Session存储在哪里?
# SESSION_ENGINE = "django.contrib.sessions.backends.db"

# 如果存储到文件中,文件的路径。
# SESSION_ENGINE = "django.contrib.sessions.backends.file"
# SESSION_FILE_PATH = None

# 存储到缓存
SESSION_ENGINE = "django.contrib.sessions.backends.cache"
SESSION_CACHE_ALIAS = "default"

此时也可以手动操作,将数据保存到redis中:

from django_redis import get_redis_connection

conn = get_redis_connection("default")
conn.set("xx","123123")
conn.get("xx")

2.3 动态菜单

不同角色的用户登录,看到不同的菜单。

  • 页面写死 HTML模板

    <html>
        {% if 角色 "管理员"%}
        	<a href="/xxx/x">用户管理</a>
        	<a href="/xxx/x">级别管理</a>
        	<a href="/xxx/x">级别管理</a>
        	...
        {% else %}
        	<a href="/xxx/x">xxx管理</a>
        	<a href="/xxx/x">级别管理</a>
        {% endif %}
    </html>
    
  • 将菜单放在配置文件中 (选择

    # settings.py
    
    ADMIN = [
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
    ]
    
    USER = [
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
        {"title":"用户管理", "url":"...." },
    ]
    
    <html>
        {% if 角色 "管理员"%}
        	{% for item in ADMIN%}
    		    <a href="{{item.url}}">{{item.title}}</a>
    	    {%emdfor%}
        {% else %}
        	{% for item in USER%}
    		    <a href="{{item.url}}">{{item.title}}</a>
    	    {%emdfor%}
        {% endif %}
    </html>
    

如果想要显示2级菜单:

ADMIN = [
    {"title":"用户管理", "url":"...." },
    {"title":"用户管理", "url":"...." },
    {"title":"用户管理", "url":"...." },
    {"title":"用户管理", "url":"...." },
]
ADMIN = [
    {
        "title":"用户管理", 
        "children":[
            {"title":"级别列表","url":"....", "name":"level_list",}
            {"title":"级别列表","url":"...."}
            {"title":"级别列表","url":"...."}
        ]
    },
    {
        "title":"订单管理", 
        "children":[
            {"title":"订单列表","url":"...."}
            {"title":"订单列表","url":"...."}
            {"title":"订单列表","url":"...."}
        ]
    },
]
  • 菜单选中和展开

    1.获取当前用户请求的 URL   pricepolicy/list/ 或 url对应的name
    2. pricepolicy/list/ 配置 ADMIN中的URL   ->默认选中
    
  • 路径导航的问题

    1.获取当前用户请求的 URL   pricepolicy/list/ 或 url对应的name
    2.获取上级,展示导航信息
    3.设置菜单与下级关系
    

2.4 权限控制

权限的判断时,要考虑:正常的点击、非法输入。

v1 = [11,22,33,44]
if 33 in v1:
    pass
v1 = {11,22,33,44}
if 33 in v1:
    pass
v1 = {
    11:123123,
    22:123123
    33:123123
    44:123123
}

if 33 in v1:
    pass
  • 文件settings.py的方式(编写)

    admin_permisions = {
        "level_list":{...},
        "level_edit":{..., 'parent':'level_list'},
        "level_add":{... 'parent':'level_list'},
        "level_delete":{..'parent':'level_list'.},
        
        "user_list":{...},
        "user_edit":{...},
        "user_add":{...},
        "user_delete":{...},
    }
    
    user_permisions = {
        ...
    }
    
    admin访问某个URL + 路由信息(name、namespace),获取当前的URL  /level/edit/4/ -> 是否存在URL
    
    在中间件中根据URL中的name进行权限的校验。
    
  • 数据库的方式

2.5 local_settings.py

线上部署和本地settings.py想要隔离,可以使用local_settings.py来进行配置。

try:
    from .local_settings import *
except ImportError:
    pass

注意:在做版本控制提交代码时,在.gitignore中设置上 local_settings.py

2.6 用户名登录

2.7 短信登录

2.8 动态菜单

2.9 权限控制
