        • Django3后端项目创建
        • 切换数据库
        • 创建Django实战项目App
        • 新建Vue.js前端项目

Django3后端项目创建
  1. 创建Django项目,采用Pycharm或者命令行创建皆可。此处,以命令行方式作为演示,项目名为django_vue

django-admin startproject django_vue

项目结构如图所示
在这里插入图片描述
2. 同步数据库文件(Django默认数据库为db.sqlite3),执行同步过程如下:

切换路径到项目目录

cd django_vue

执行同步

python manage.py migrate

PS E:\coding\Django_learn\django_vue> python manage.py migrate

OKApplying auth.0012_alter_user_first_name_max_length... OKApplying sessions.0001_initial... OK
PS E:\coding\Django_learn\django_vue>
  1. 启动Django Server ,验证默认配置是否正常。

python manage.py runserver

PS E:\coding\Django_learn\django_vue> python manage.py runserver

切换数据库
  1. Django数据库更换为Mysql

登录mysql

mysql -u root -p

在这里插入图片描述
2. 创建数据库,数据库取名为django_vue_db,并设置字符集为utf-8

mysql> CREATE DATABASE django_vue_db CHARACTER SET utf8;
Query OK, 1 row affected, 1 warning (0.15 sec)
  1. 安装myslqclient

  2. 配置settings.py文件,配置Mysql数据库引擎。

DATABASES = {'default': {'ENGINE': 'django.db.backends.mysql','NAME': 'django_vue_db','USER': 'root','PASSWORD': 'xxxxxxx','HOST': '127.0.0.1',}
}
  1. 执行同步操作,将数据迁移到Mysql

python manage.py migrate

S E:\coding\Django_learn\django_vue> python manage.py migrate
>>

OKApplying auth.0012_alter_user_first_name_max_length... OKApplying sessions.0001_initial... OK
  1. 验证是否切库成功,进入到Mysql客户端,查看django初化表是否有生成。
mysql> use django_vue_db;
Database changed
mysql> show tables;
+----------------------------+
| Tables_in_django_vue_db    |
+----------------------------+
| auth_group                 |
| auth_group_permissions     |
| auth_permission            |
| auth_user                  |
| auth_user_groups           |
| auth_user_user_permissions |
| django_admin_log           |
| django_content_type        |
| django_migrations          |
| django_session             |
+----------------------------+
10 rows in set (0.00 sec)
  1. 运行Django Server,重新访问http://localhost:8000
    如果能正常访问,过程没有报错,说明切换数据库已经成功了。
创建Django实战项目App
  1. 创建Django App,进入django_vue项目主目录,输入如下命令:

python manage.py startapp api_test

  1. App创建完成后,目录结构如下所示:
    在这里插入图片描述

并把api_test加入到settings文件中的installed_apps列表里:

INSTALLED_APPS = ['django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','api_test',
]
  1. api_test目录下的models.py里写一个model

from __future__ import unicode_literals
from django.db import models
class Book(models.Model):book_name = models.CharField(max_length=128)add_time = models.DateTimeField(auto_now_add=True)def __unicode__(self):return self.book_name

只有两个字段,书名book_name和添加时间add_time。如果没有指定主键的话Django会自动新增一个自增id作为主键。

  1. api_test目录下的views里我们新增两个接口,一个是show_books返回所有的书籍列表(通过JsonResponse返回能被前端识别的json格式数据),二是add_book接受一个get请求,往数据库里添加一条book数据。
from django.shortcuts import render
from django.views.decorators.http import require_http_methods
from django.core import serializers
from django.http import JsonResponse
import jsonfrom .models import Book@require_http_methods(["GET"])
def add_book(request):response = {}try:book = Book(book_name=request.GET.get('book_name'))book.save()response['msg'] = 'success'response['error_num'] = 0except  Exception as e:response['msg'] = str(e)response['error_num'] = 1return JsonResponse(response)@require_http_methods(["GET"])
def show_books(request):response = {}try:books = Book.objects.filter()response['list'] = json.loads(serializers.serialize("json", books))response['msg'] = 'success'response['error_num'] = 0except  Exception as e:response['msg'] = str(e)response['error_num'] = 1return JsonResponse(response)
  1. api_test目录下,新增一个urls.py文件,把我们新增的两个接口添加到路由里:
from django.conf.urls import url, include
from .views import *urlpatterns = [url(r"add_book$", add_book, ),url(r"show_books$", show_books, ),
]
  1. 我们还要把api_test下的urls添加到项目django_vue下的urls中,才能完成路由:
from django.contrib import admin
from django.urls import path
from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView
import api_test.urlsurlpatterns = [url(r"^admin/", admin.site.urls),url(r'^api/', include(api_test.urls)),
]
  1. 在项目的根目录,输入命令:
python manage.py makemigrations api_test
python manage.py migrate
  1. 查询数据库,看到book表已经自动创建了:
PS E:\coding\Django_learn\django_vue> python manage.py makemigrations api_test
>>
Migrations for 'api_test':api_test\migrations\0001_initial.py+ Create model Book
PS E:\coding\Django_learn\django_vue> python manage.py migrate
>>
Operations to perform:Apply all migrations: admin, api_test, auth, contenttypes, sessions
Running migrations:Applying api_test.0001_initial... OK

在这里插入图片描述
Django生成的表名将以app名加上model中的类名组合而成。

新建Vue.js前端项目

有关Vue的模块(包括vue)可以使用node自带的npm包管理器安装。推荐使用淘宝的 cnpm 命令行工具代替默认的 npm

npm install -g cnpm --registry=https://registry.npm.taobao.org
  1. 先用cnpm安装vue-cli脚手架工具(vue-cli是官方脚手架工具,能迅速帮你搭建起vue项目的框架):

cnpm install -g vue-cli

PS E:\coding\Django_learn\django_vue> cnpm install -g vue-cli

  1. 现在我们可以看到整个文件目录结构是这样的:

在这里插入图片描述
6. 在frontend目录src下包含入口文件main.js,入口组件App.vue等。后缀为vue的文件是Vue.js框架定义的单文件组件,其中标签中的内容可以理解为是类html的页面结构内容。

  1. src/component文件夹下新建一个名为Home.vue的组件,通过调用之前在Django上写好的api,实现添加书籍和展示书籍信息的功能。在样式组件上我们使用了饿了么团队推出的element-ui,这是一套专门匹配Vue.js框架的功能样式组件。
