2.Models设计

1.Models设计：

1.重构用户表：

1.在users/models.py中：

from django.db import models
from django.contrib.auth.models import AbstractUser
from datetime import datetime
# Create your models here.


class UserProfile(AbstractUser):
    """
    用户表
    """
    token = models.CharField(max_length=64, null=True, blank=True, verbose_name='token')
    mobile = models.CharField(max_length=11, null=True, blank=True,verbose_name='电话')

    class Meta:
        verbose_name='用户'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

2.在settings.py中配置

AUTH_USER_MODEL='users.UserProfile'

3.在终端执行数据更新命令，生成数据表

由于重构了用户数据表，所以需要先注释掉settings.py中的：

'django.contrib.admin',

 

 然后执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

然后再去掉注释

 

 如果没有这一步，直接执行数据更新命令，则会报错：

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applie

 2.产品项目案例表

1.安装DjangoUeditor

软件的信息中使用到了富文本编辑框，所以要储存富文本文件。

1.将DjangoUeditor包放到extra_apps目录下

2.在settings.py中注册DjangoUeditor

 

  3.在newnet/urls.py中配置富文本路由：

from django.contrib import admin
from django.urls import path,include
from django.views.static import serve
from newnet.settings import MEDIA_ROOT
from django.views.generic import TemplateView

urlpatterns = [
    path('admin/', admin.site.urls),
    path('media/<path:path>',serve,{'document_root':MEDIA_ROOT}),
    path('', TemplateView.as_view(template_name='index.html'), name='index'),
    path('good/', include('good.urls',namespace='goods')),
    path('ueditor/',include('DjangoUeditor.urls' ))

]

2.apps/good/models.py：

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


class Case(models.Model):
    """
    项目
    """
    user = models.ForeignKey(UserProfile, verbose_name="编辑者", on_delete=models.CASCADE)
    img = models.ImageField(upload_to='img', null=True,verbose_name='封面')
    name = models.CharField(default="", max_length=30, verbose_name="项目名", help_text="项目名")
    type = models.CharField(default="普通项目", max_length=10, verbose_name="项目类型", help_text="项目类型")
    goods_desc = UEditorField(verbose_name=u"内容", imagePath="goods/images/", width=1000, height=900,
                              filePath="goods/files/", default='')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "项目案例"
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name

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

    image_url.short_description = '封面'


class News(models.Model):
    """
    新闻
    """
    is_banner=models.BooleanField(default=False,verbose_name='是否轮播')
    banner=models.ImageField(upload_to='banner', null=True,blank=True,verbose_name='轮播图')
    user = models.ForeignKey(UserProfile, verbose_name="编辑者", on_delete=models.CASCADE)
    img = models.ImageField(upload_to='img',verbose_name='封面')
    title = models.CharField(default="", max_length=30, verbose_name="新闻标题", help_text="新闻标题")
    desc = models.CharField(default="详细介绍", max_length=30, verbose_name="详细介绍", help_text="详细介绍")
    goods_desc = UEditorField(verbose_name=u"内容", imagePath="goods/images/", width=1000, height=900,
                              filePath="goods/files/", default='')
    num=models.IntegerField(default=0,verbose_name='阅读量')
    fav=models.IntegerField(default=0,verbose_name='赞数')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "新闻"
        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.img))

    image_url.short_description = '封面'

 

然后执行数据更新命令：

python manage.py makemigrations
python manage.py migrate

3.关于我们和联系我们数据表

1.apps/user_operation/models.py：

from django.db import models
from datetime import datetime
from DjangoUeditor.models import UEditorField
# Create your models here.


class AboutMe(models.Model):
    """关于我们"""
    goods_desc = UEditorField(verbose_name=u"内容", imagePath="goods/images/", width=800, height=900,
                              filePath="goods/files/", default='')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "关于我们"
        verbose_name_plural = verbose_name


class CallMe(models.Model):
    """
    联系我们
    """
    name = models.CharField(default="", max_length=30, verbose_name="姓名", help_text="姓名")
    mail = models.CharField(default="", max_length=30, verbose_name="邮箱", help_text="邮箱")
    text=models.CharField(default="",max_length=500,verbose_name='内容',help_text='最长500字')
    add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")

    class Meta:
        verbose_name = "联系我们"
        verbose_name_plural = verbose_name

然后执行数据更新命令：

python manage.py makemigrations
python manage.py migrate
