越光后端开发——ygapi（2.新建Model）

1.新建Model

1.users数据

1.在apps/users/models.py中：

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

# Create your models here.

class UserProfile(AbstractUser):
    """
    管理员
    """
    name=models.CharField(max_length=30,null=True,blank=True,verbose_name='姓名')
    mobile=models.CharField(max_length=11,null=True,blank=True,verbose_name='电话')

    class Meta:
        verbose_name='管理员'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

class WxUsers(models.Model):
    """
    微信用户
    """
    open_id=models.CharField(max_length=64,null=True,blank=True,verbose_name='OpenId')
    token=models.CharField(max_length=64,null=True,blank=True,verbose_name='token')
    nickName=models.CharField(max_length=30,null=True,blank=True,verbose_name='微信名')
    avatarUrl=models.CharField(max_length=200,null=True,blank=True,verbose_name='用户头像URL')
    gender = models.CharField(max_length=4, choices=((',
                              verbose_name='性别')
    province=models.CharField(max_length=20,null=True,blank=True,verbose_name='用户所在省')
    city=models.CharField(max_length=20,null=True,blank=True,verbose_name='用户所在市')
    country=models.CharField(max_length=20,null=True,blank=True,verbose_name='用户所在旗县区')
    longitude=models.CharField(max_length=10,null=True,blank=True,verbose_name='经度')
    latitude=models.CharField(max_length=10,null=True,blank=True,verbose_name='纬度')
    last_login_time = models.DateTimeField(default=datetime.now, verbose_name="最后登录时间")
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name='微信用户'
        verbose_name_plural=verbose_name

    def __str__(self):
        return self.nickName

2.在settings.py中增加配置项

AUTH_USER_MODEL='users.UserProfile'

3.执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

2.wish数据

1.apps/wish/models.py中

from django.db import models
from users.models import WxUsers,UserProfile
from datetime import datetime
from django.utils.safestring import mark_safe
# Create your models here.

class Wish(models.Model):
    """
    愿望表
    """
    wxuser=models.ForeignKey(WxUsers,on_delete=models.CASCADE)
    content=models.CharField(max_length=200,default='',verbose_name='愿望内容',help_text='最多200字')
    status=models.CharField(max_length=8, choices=((',
                              verbose_name='阶段')
    pv_num=models.IntegerField(default=0,verbose_name='浏览数')
    up_num=models.IntegerField(default=0,verbose_name='点赞数')
    share_num=models.IntegerField(default=0,verbose_name='转发数')
    bb_num=models.IntegerField(default=0,verbose_name='评论数')
    end_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name='愿望表'
        verbose_name_plural=verbose_name

    def __str__(self):
        return self.content

class News(models.Model):
    """
    新闻表
    """
    user=models.ForeignKey(UserProfile,on_delete=models.CASCADE)
    banner=models.ImageField(max_length=200, upload_to='banner/',verbose_name='轮播图')
    title=models.CharField(max_length=15,default='',verbose_name='新闻标题',help_text='最多15字')
    content=models.CharField(max_length=800,default='',verbose_name='新闻正文',help_text='最多800字')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name='新闻表'
        verbose_name_plural=verbose_name

    def __str__(self):
        return self.title

    def image_url(self):
        return mark_safe('<img src="/media/{0}" class="field_img">'.format(self.banner))

    image_url.short_description = '轮播图'

class Images(models.Model):
    """
    新闻图片
    """
    image = models.ImageField(max_length=200, upload_to='images/')
    news=models.ForeignKey(News, verbose_name="新闻", blank=True,null=True,on_delete=models.CASCADE)
    add_time = models.DateTimeField(default=datetime.now, verbose_name='添加时间')

    class Meta:
        verbose_name = "新闻图片"
        verbose_name_plural = verbose_name

    def image_url(self):
        return mark_safe('<img src="/media/{0}" class="field_img">'.format(self.image))

    image_url.short_description = '图片'

2.安装 pillow包（做图片处理的）

pip install pillow

3.执行数据更新命令：

python manage.py makemigrations
python manage.py migrate
