Django Development Web site steps

1. Create a Django Project

Django-admin Startproject Project Name

2. Create an App

CD project name Python manage.py Startapp CMDB

3. Static file Configuration

Edit project.settings.py, append the following:

Staticfiles_dirs = (Os.path.join (base_dir, "Static"),)

4. Template path Configuration

DIRS ==> (Os.path.join (base_dir, ' templates '),)

5, settings, note csrf

middleware_classes = (# ' Django.middleware.csrf.CsrfViewMiddleware ',)

6, define the routing rules, in url.py define the URL of user access by which function to process the request

url.py "Login"---Name of function

7, define the View function, define the function in views.py

def func (reuest): # request.method Get/post # http://127.0.0.1:8000/home?nid=123&name=bob # request. Get.get (", None) #获取请求发来的数据 # request. Post.get (", None) # return HttpResponse (" string ") # return Render (Request, ' HTML template path ', {" User_list ": User_list}) # RE Turn redirect (' Can only fill in URLs, for example:/home ')

8. Template rendering

Django's special template language, such as:

--Variable Name value--

Define the variables and corresponding values in views.py, and use {{Var_name}} in the template's HTML page to take the value

def func (Request): Return render (Request, "index.html", {' Current_User ': "Bob"}) Index.html

--for Loop Value--
Define lists and values in views.py, and use {{for loop}} in the template's HTML page to take the value
def func (Request): Return render (Request, "index.html", {' Current_User ': "Bob", ' user_list ': [' Bob ', ' aaa ', ' BBB ']}) I         ndex.html

--Index value--
Define the dictionary and value in views.py, and use {{Var_name.key}} in the template's HTML page to take the value
def func (Request): Return render (Request, "index.html", {' Current_User ': "Bob", ' user_list ': [' Bob ', ' AAA ')  , ' BBB '], ' user_dict ': [' K1 ': ' v1 ', ' K2 ': ' V2 ']}) index.html

--Condition value--
{% if%}
{% if%}
{% ENDIF%}
{% else%}
{% Else%}
{% ENDIF%}
Def func (Request):     return render (Request, "index.html",{          ' Current_User ':  "Bob",           ' age ': 18,         ' user_list ':  [' Bob ', ' aaa ', ' BBB ',          ' user_dict ':  [' K1 ':  ' v1 ',  ' K2 ':  ' v2 ']         })         index.html 

Workflow for templates:

 
    

  
     
 
      
1. When a user requests a request via a URL, the Django route sends the request to the view function,
 
      
2, then the view function will first go to the template,
 
      
3. Render the variable with {{Current_User}} in the template with the value defined in the view and convert the template content to a string after rendering
 
      
4. Return the generated string as a whole to the user
 
     
 
    


Filter filters
Template filters are the way that variables are converted before they are displayed, and look like this
{{Name|lower}}
This displays the value of the {{name}} variable filtered by the lower filter, which converts the text to lowercase
Use (|) Pipeline to apply for a filter

filters can be strung into chains, that is, the result of a filter can be passed to the next, The following is the customary usage of escape text content and then convert the newline to P tags
{{My_text|escape|linebreaks}}
