❶ django rest framework中文介绍
注意:这是版本3的文档。还提供了版本2的文档。
Django REST framework 是一个强大且灵活的工具包,用以构建Web APIs。
为什么要使用REST framework?
REST framework is a collaboratively(合作地) funded project(基金项目). If you use REST framework commercially(商业化的) we strongly(强烈) encourage(建议) you to invest(投资) in its continued development(可持续发展) by signing up for a paid plan .(注册付费计划)
Every single(每次简单) sign-up helps us make REST framework long-term financially(财政上) sustainable(财务上可持续发展)

REST framework 有以下的要求:
python (2.7, 3.2, 3.3, 3.4, 3.5,3.6)
Django (1.7+, 1.8, 1.9,,2.0)
下面是可选的包:
Install using pip , including any optional packages you want...(使用pip安装,包括任何你想要的可选包裹...)
...or clone the project from github.(或者从GitHub复制项目)
Add 'rest_framework' to your INSTALLED_APPS setting.
If you're intending to use the browsable API you'll probably also want to add REST framework's login and logout views. Add the following to your root urls.py file.(如果您打算使用可浏览的API,您可能还需要添加REST框架的登录和注销视图。将以下内容添加到您的根urls.py文件中。)
Note that the URL path can be whatever you want.(注意,url路径可以是任何你想要的。)
Let's take a look at a quick example of using REST framework to build a simple model-backed API.让我们来看看一个使用REST framework构建一个简单模型支持api的快速示例。
We'll create a read-write API for accessing information on the users of our project.(我们将创建一个读写api,用于访问项目用户的信息。)
Any global settings for a REST framework API are kept in a single configuration dictionary named REST_FRAMEWORK . Start off by adding the following to your settings.py mole:(REST framework api的任何全局设置都保存在一个名为“rest_wramework”的配置词典中。首先在“环境”模块中添加以下内容:)
Don't forget to make sure you've also added rest_framework to your INSTALLED_APPS .(别忘了确保你已经在“INSTALLED_APPS”中添加了“rest_framework”。)
We're ready to create our API now. Here's our project's root urls.py mole:(我们准备好创建我们的api了。这是我们项目的根源 urls.py 模块:)
You can now open the API in your browser at http://127.0.0.1:8000/ , and view your new 'users' API. If you use the login control in the top right corner you'll also be able to add, create and delete users from the system.(现在,您可以在浏览器中输入‘http://127.0.0.1:8000/’打开api,并查看您的新“用户”api。如果您使用右上角的登录控件,您也可以从系统中添加、创建和删除用户。)
Can't wait to get started? The quickstart guide is the fastest way to get up and running, and building APIs with REST framework.(等不及要开始了?快速启动指南是最快的建立和运行的方式,并建立REST framework的apis。)
The tutorial will walk you through the building blocks that make up REST framework. It'll take a little while to get through, but it'll give you a comprehensive understanding of how everything fits together, and is highly recommended reading.(本教程将帮助您完成组成REST框架的构建块。这需要一点时间来完成,但是它会给你一个全面的理解如何把一切结合起来,并强烈推荐阅读。)
There is a live example API of the finished tutorial API for testing purposes, available here .这里有一个用于测试目的的完成教程API的实例化API,这里可获得
The API guide is your complete reference manual to all the functionality provided by REST framework.(API指南是您对REST框架提供的所有功能的完整参考手册)
General guides to using REST framework.(使用REST框架的一般指南。)
See the Contribution guidelines for information on how to clone the repository, run the test suite and contribute changes back to REST Framework.(有关如何克隆存储库、运行测试套件以及向REST框架贡献更改的信息,请参阅贡献指南。)

❷ 什么是django
Django是用Python开发的一个免费开源的Web框架,提供了许多网站后台开发经常用到的模块,使开发者能够专注于业务部分。并且囊括的Web应用部分可以用于快速搭建高性能、优雅的网站。并且提供了通用Web开发模式的高度抽象,通过DRY的理念为频繁进行的编程作业提供了快速解决方法。
Django能在开源发行之后吸引众多追随者,离不开它所具备的以下优点:
①齐全的功能。自带大量常用工具和框架,可轻松、迅速开发出一个功能齐全的Web应用。
②完善的文档。Django已发展十余年,具有广泛的实践案例,同时Django提供完善的在线文档,Django用户能够更容易地找到问题的解决方案。
③强大的数据库访问组件。Django自带一个面向对象的、反映数据模型与关系型数据库间的映射关系的映射器,开发者无须学习sql语言即可操作数据库。
④灵活的URL映射。Django提供一个基于正则表达式的URL分发器,开发者可灵活地编写URL。
⑤丰富的模板语言。Django模板语言功能丰富,支持自定义模板标签;Django也支持使用第三方模板系统,如jinja2等。
⑥健全的后台管理系统。Django内置了一个后台数据管理系统,经简单配置后,再编写少量代码即可使用完整的后台管理功能。
⑦完整的错误信息提示。Django提供了非常完整的错误信息提示和定位功能,可在开发调试过程中快速定位错误或异常。
⑧强大的缓存支持。Django内置了一个缓存框架,并提供了多种可选的缓存方式。
⑨国际化。Django包含了一个国际化系统,Django组件支持多种语言。
❸ Django 运行开发服务器时报错是怎么回事
原因如下:
1、因代码中的中文注释问题的报错
django项目的.py文件文件中加入了中文注释,经常会因此报错而导致无法运行,究其原因是编码的问题,最后的解决办法是直接在有中文注释的.py文件的顶部加上:# -*-coding:utf-8 -*-
2、运行过程中的中文乱码的报错
(1)首先确保连接的数据库的基础设置是utf-8。
(4).debian里需要在~/.bashrc里面最下面加入export LC_ALL=zh_CN.UTF-8或者直接运行export.UTF-8。
(5).最后直接reboot重启服务器,查看系统编码,UTF-8中文生效,locale命令可以直接查看系统编码设置,此时再运行django项目上传中文名文件无误。
❹ django需要安装mysql数据库吗
django需要安装mysql数据库
方法/步骤
修改setting.py里面的DATABASES元组为
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'books', #你的数据库名称
'USER': 'root', #你的数据库用户名
'PASSWORD': '', #你的数据库密码
'HOST': '', #你的数据库主机,留空默认为localhost
'PORT': '3306', #你的数据库端口
}
}
INSTALLED_APPS = (
'books',#你的数据库名称
)
在mysql里面创建books数据库
检查配置是否有语法错误
使用python manage.py sqlall books 显示mysql语法
使用python manage.py syncdb同步模型中的数据库
创建成功!
❺ Django搭配什么数据库
Django默认的数据库是sqlite,也可以使用其它主流的数据库,推荐使用Mysql
