Django完整项目

一、项目预览：（关于喜羊羊与灰太狼简介项目）

二、功能介绍

1、主要用户可以进行注册账号，登录信息进入首页当中，修改密码，修改个人信息及个人头像。（数据库信息）。

2、观看喜羊羊与灰太狼的简单的介绍信息。

三、项目前期配置

1、创建一个django项目。

2、在 yangcun项目中创建一个app （在工具栏中选中Run manage.py Task…）在框中输入 startapp (app名)  创建app。

3、注册app（在settings.py配置文件中找到INSTALLED_APPS在里面注册app），以及配置settings文件。

4、创建文件夹。

       在users app中创建一个static文件夹，以及templates文件夹、把views.py文件删除，创建views文件夹、创建一个urls.py文件。在yangcun文件夹中创建一个media文件夹。

 5、打开yangcun文件夹中的urls.py文件，在里面输入如下代码：

yangcun>urls.py:

from django.urls import path,include,re_path
from django.views.static import serve
from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    path('user/', include("users.urls")),
    re_path('^media/(?P<path>.*)$', serve, {'document_root' : settings.MEDIA_ROOT}),
] + static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

四、后端完整代码

在users>models.py中:

from django.db import models

# Create your models here.


# 用户表
class User(models.Model):
    name = models.CharField(verbose_name="用户名",max_length=64)
    account = models.CharField(verbose_name="账号",max_length=64)
    password = models.CharField(verbose_name="密码",max_length=64)
    img = models.ImageField(verbose_name="头像",max_length=255,upload_to="imgs",null=True)
    age = models.IntegerField(verbose_name="年龄",null=True)
    sex = models.CharField(verbose_name="性别",max_length=11,null=True)  # True 是 男生   False 是女生
    phone = models.CharField(verbose_name="联系方式",max_length=11,null=True)
    introduction = models.TextField(verbose_name="个人简介",null=True)
    time = models.DateTimeField(verbose_name="注册时间",auto_now=True)

然后执行：python3 manage.py makemigrations 和 Python3 manage.py migrate

在users>urls.py中：

"""yangcun URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
