Background Requirements Analysis
Use Django+ajax background scenarios when users fill out a very detailed registration application form! The most worrying thing for users is to be disturbed during the filling of the form, followed by the hope to fill out the table after the submission of any mistakes, otherwise you have to new! Therefore, the first thing we think of is the possibility of using Ajax to deal with. The introduction of Ajax is usually based on the PHP background writing mode, I have never used PHP to write the server, so looking for a job for me is a nightmare ah!
Development environment Preparation
Here I'll show you how to build and configure our Django environment, and the various codes we write later, if not specifically stated, are based on this project environment!
Python 2.7.101.8.6
Development Steps Demo
1) Build Projects & Applications
CD src
django-admin.py Startproject Ajaxsample
CD Ajaxsample
django-admin.py Startapp Poll
The basic configuration directory structure is as follows:
SRC ajaxsample ajaxsample poll manage.py db.sqlite3
2) Create a static file
mkdir src/static_in_env_ajaxsample/mkdir src/static_in_env_ajaxsample/static_root/mkdir src/ ajaxsample/static_in_pro/mkdir src/ajaxsample/static_in_pro/our_static/mkdir src/ ajaxsample/static_in_pro/our_static/js/mkdir src/ajaxsample/static_in_pro/our_static/css/
3) Configure static files (src/ajaxsample/ajaxsample/settings.py)
Add app poll to your project
#application DefinitionInstalled_apps= ( 'Django.contrib.admin', 'Django.contrib.auth', 'Django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'Django.contrib.staticfiles', 'Poll',)
Set the static file path
#Static files (CSS, JavaScript, Images)#https://docs.djangoproject.com/en/1.8/howto/static-files/Static_url='/static/'Static_root= Os.path.join (Os.path.dirname (Base_dir),"Static_in_env_ajaxsample","Static_root") Staticfiles_dirs=[Os.path.join (Base_dir,"Static_in_pro","our_static"),]media_url='/media/'Media_root= Os.path.join (Os.path.dirname (Base_dir),"Static_in_env_ajaxsample","Media_root")
4) running the Django component
Python manage.py collectstatic
Next you will be asked to check the path without errors directly select Yes
5) test each configuration is normal
#1由于我们没有配置templates文件, so we set up a templates directly under the poll directory
mkdir poll/templates/
CD templates
#2先在你已经到templates文件目录下啦! You can start writing hello.html files!
<HTML><Head><title>Welcome</title></Head><Body><H1>Hello world!</H1></Body></HTML>
#3写一个视图 (src/ajaxsample/poll/views.py)
def Hello (Request): return render (request,"hello.html", {})#4创建一个urls. PY (src/ajaxsample/poll/urls.py)
from Import fromimport = [url (r ' ^hello/$ ', ' Poll.views.hello ' ),]
#5为了让项目知道你创建了一个urls. py configuration file, you need to configure the urls.py in the project
from Import fromimport = [url (r ' ^admin/') , include (Admin.site.urls)), URL (r', include ('poll.urls' ) )),]#6现在可以运行开发服务器啦!
Python manage.py runserver
#7到你的浏览器看看吧! (http://127.0.0.1:8000/hello/)

The first part is over, let me know if you have any suggestions.
