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 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

创建Django实战项目App
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 App创建完成后目录结构如下所示
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,
]在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_length128)add_time models.DateTimeField(auto_now_addTrue)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。
在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 Bookrequire_http_methods([GET])
def add_book(request):response {}try:book Book(book_namerequest.GET.get(book_name))book.save()response[msg] successresponse[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] successresponse[error_num] 0except Exception as e:response[msg] str(e)response[error_num] 1return JsonResponse(response)在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(radd_book$, add_book, ),url(rshow_books$, show_books, ),
]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)),
]在项目的根目录输入命令
python manage.py makemigrations api_test
python manage.py migrate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_testMigrations for api_test:api_test\migrations\0001_initial.py Create model Book
PS E:\coding\Django_learn\django_vue python manage.py migrateOperations to perform:Apply all migrations: admin, api_test, auth, contenttypes, sessions
Running migrations:Applying api_test.0001_initial... OKDjango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
