pycharm python is a very good development tools, greatly reducing the python project creation time and debugging time
after using python script to write for some time, want to try using Django to write a python project, now do the following recording notes:
1. Create a project
If the local version is not installed corresponding to the selected version of Django python, pycharm automatically download the appropriate versions:
After you create to run the project, the default page for the http://127.0.0.1:8000/ , open:
Appears above the page, the project to create positive success
Directory Structure:
2, create APP
In Django project may comprise a plurality of APP, corresponding to a large-scale project in the subsystem, sub-module, functional components and others, more independent from each other, but there are also links all the resources shared project APP
Input: python manage.py startapp myapp
generate myapp folder
3, and the view configuration url
myapp / views.py file code:
from django.http import HttpResponse #需要导入HttpResponse模块
def hello(request): #request参数必须有，名字类似self的默认规则，可以修改，它封装了用户请求的所有内容
return HttpResponse("Hello world ! ") #不能直接字符串，必须是由这个类封装，此为Django规则testDjango / urls.py file code:
from myapp import views #首先需要导入对应APP的views
urlpatterns = [
url(r'^admin/', admin.site.urls), #admin后台路由
url(r'^hello$', views.hello), #你定义的路由，第一个参数为引号中的正则表达式，第二个参数业务逻辑函数（当前为views中的hello函数）
]Run the project:
the command line is: python manage.py runserver 127.0.0.1:8000
but you can use the following methods in pycharm in:
4, Django template
Modify file views:
def hello(request):
# return HttpResponse("Hello world ! ")
context = {}
context['hello'] = 'Hello World!' #数据绑定
return render(request, 'hello.html', context) #将绑定的数据传入前台Inherited template:
{#base.html#}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>模板测试</title>
</head>
<body>
<h1>{{ hello }}</h1>
<p>Django模板测试</p>
{% block mainbody %}
<p>original</p>
{% endblock %}
</body>
</html>hello.html inherited base.html, and replacement of particular block, the code hello.html modified as follows:
{#hello.html#}
{% extends "base.html" %}
{% block mainbody %}<p>继承了 base.html 文件</p>
{% endblock %}Revisit address http://127.0.0.1:8000/hello , output results are as follows:
5, the introduction of static files
Needs to be some static resources into the project, create a static directory, js, css and other files can be placed in this directory:
Django need to find this directory, you need to configure the setting file:
The introduction of static resources in the html file:
{% load staticfiles %}
{#base.html#}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="{% static 'css/mypage.css' %}">
<script src="{% static 'js/jquery-1.11.1.js' %}"></script>
<title>模板测试</title>
</head>
<body>
<h1>{{ hello }}</h1>
<p>Django模板测试</p>
{% block mainbody %}
<p>original</p>
{% endblock %}
</body>
</html>The first line of the file path is introduced static {% load staticfiles%}, was added in the <head> ... </ head> js li CSS files and the network chain
