Vue Django Restful framework 前后端

直接开始了

1：环境的搭建

需要用的，nodejs, npm(cnpm)，djangorestfulframework，mysql等

2：项目结构

在项目里构建一个apps的文件夹，专门用于存放所有的app
这个不同于上次我自己做的项目，各个app都是并列于根目录下，这个专门统一存放了。

3 Models建模

3.1 Users

class UserProfile(AbstractUser):

    """
    User
    """
    name = models.CharField(max_length=30,null=True,blank=True,verbose_name='姓名')
    birthday = models.DateField(null=True,blank=True,verbose_name='出生年月')
    gender = models.CharField(max_length=6,choices=(('male','男'),('femal','女')),default='female',verbose_name='性别')
    mobile = models.CharField(max_length=11,verbose_name='电话')
    email = models.CharField(max_length=100,null=True,blank=True,verbose_name='邮箱')

    class Meta:

        verbose_name = '用户'
        verbose_name_plural = '用户'

    def __str__(self):
        return self.name

    """
    SMS verficiation
    """
    code = models.CharField(max_length=10,verbose_name='验证码')
    mobile = models.CharField(max_length=11,verbose_name='电话')

    # 注意datetime.now的用法，没有双括号，不然这个字段生成的时间会是建模的时间
    add_time = models.DateTimeField(default=datetime.now,verbose_name='添加时间')

    class Meta:
        verbose_name = '短信验证码'

3.2 Goods货物

3.3 Trade交易

这里主要建立购物车，订单信息，订单货物信息等模型

from django.db import models
from datetime import datetime
from django.contrib.auth import get_user_model

from goods.models import Goods
# Create your models here.

User = get_user_model() #利用在settings里面设置的AUTH_USER_MODEL，来获取User的类,get_user_model()内部就是读取settings里面设置

class ShoppingCart(models.Model):
    """
    购物车
    """
    user = models.ForeignKey(User,verbose_name="用户",on_delete=models.DO_NOTHING)
    goods = models.ForeignKey(Goods,verbose_name="商品",on_delete=models.DO_NOTHING)
    goods_num = models.IntegerField(default=0,verbose_name="购买数量")

    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')

    class Meta:
        verbose_name = "购物车"
        verbose_name_plural = verbose_name

    def __str__(self):
        return "%s(%d)".format(self.goods.name,self.goods_num)


class OrderInfo(models.Model):
    """
    订单信息
    """

    ORDER_STATUS = (
        ("success","成功"),
        ("cancel","取消"),
        ("cancel","待支付"),
    )



    user = models.ForeignKey(User, verbose_name="用户",on_delete=models.DO_NOTHING)
    order_sn = models.CharField(max_length=30,verbose_name="订单号")
    trade_no = models.CharField(max_length=100,unique=True,null=True,blank=True,verbose_name="交易单号")
    pay_status = models.CharField(choices=ORDER_STATUS,max_length=10,verbose_name="订单支付状态")
    post_script = models.CharField(max_length=200,verbose_name="订单留言")
    order_amount = models.FloatField(default=0.0,verbose_name="订单金额")
    pay_time = models.DateTimeField(null=True,blank=True,verbose_name="支付时间")

    #用户信息
    address = models.CharField(max_length=100,default="",verbose_name="收货地址")
    sign_name = models.CharField(max_length=20,default="",verbose_name="签收人")
    signer_mobile = models.CharField(max_length=11,verbose_name="联系电话")

    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')


    class Meta:

        verbose_name_plural = verbose_name

    def __str__(self):
        return str(self.order_sn)


class OrderGoods(models.Model):
    """
    订单详情
    """

    order = models.ForeignKey(OrderInfo,verbose_name="订单信息",on_delete=models.DO_NOTHING)
    goods = models.ForeignKey(Goods,verbose_name="商品",on_delete=models.DO_NOTHING)
    goods_num = models.IntegerField(default=0,verbose_name="商品数量")

    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')

    class Meta:

        verbose_name = "订单商品"
        verbose_name_plural = verbose_name

    def __str__(self):
        return str(self.order.order_sn)

3.4 用户操作模型

from datetime import datetime
from django.contrib.auth import get_user_model

from goods.models import Goods
# Create your models here.

User = get_user_model() #利用在settings里面设置的AUTH_USER_MODEL，来获取User的类,get_user_model()内部就是读取settings里面设置


class UserFav(models.Model):

    user = models.ForeignKey(User,verbose_name="用户",on_delete=models.DO_NOTHING)
    goods = models.ForeignKey(Goods,verbose_name="商品",on_delete=models.DO_NOTHING)

    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')

    class Meta:
        verbose_name = "用户收藏"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.user.name


class UserLeavingMessage(models.Model):
    """
    用户留言
    """

    MESSAGE_CHOICES = (
        (1, "留言"),
        (2, "投诉"),
        (3, "询问"),
        (4, "售后"),
        (5, "求购"),
    )

    user = models.ForeignKey(User,verbose_name="用户",on_delete=models.DO_NOTHING)
    message_type = models.IntegerField(default=1,choices=MESSAGE_CHOICES,verbose_name="留言类型",
                                       help_text="留言类型:1(留言),2(投诉),3(询问),4(售后),5(求购)")
    subject = models.CharField(max_length=100,default="",verbose_name="主题")
    message = models.TextField(default="",verbose_name="留言内容",help_text="留言内容")
    file = models.FileField(verbose_name="上传的文件",help_text="上传的文件")

    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')

    class Meta:
        verbose_name = "用户留言"
        verbose_name_plural = verbose_name


    def __str__(self):
        return self.subject


class UserAddress(models.Model):
    """
    用户收货地址

    class Meta:
        verbose_name = "用户收货地址"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.address

4:注意事项

1：Django 2.0以后，所有的外键都必须加上on_delete参数
2：在settings里面设置mysql的时候，OPTION选项设置时要加一个default

DATABASES = {
    # 'default': {
    #     'ENGINE': 'django.db.backends.sqlite3',
    #     'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    # }
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': "mxshop",
        'USER':'root',
        'PASSWORD':',
        'HOST': "127.0.0.1",
        'PORT':'3306',
        'OPTIONS':{'init_command': 'SET default_storage_engine = INNODB;'}
    }
}
