Page Static Processing Mode Triggered by Timing Task in Django

There are many different Web frameworks under Python. Django is the most representative of heavyweights. Many successful websites and APP are based on Django.
Django is an open source Web application framework written by Python.
Django, copyrighted by BSD, was first released in July 2005 and the first official version 1.0 was released in September 2008.
Django adopts the software design pattern of MVC, namely model M, view V and controller C.

This chapter introduces the static processing mode of triggering pages through timed tasks in Django. The specific contents are as follows:

Installation

pip install django-crontab

Add an application

INSTALLED_APPS = [
  ...
  'django_crontab', #  Timing task 
  ...
]

Set the timing time of the task

Set the timed execution time in the configuration file

Each timed task is defined in three parts:

Task time

Basic format:

* * * * *

Time-sharing sun, moon and week order

M: Minutes (0-59). Each minute is denoted by * or */1

H: Hours (0-23). (0 denotes 0 point)

D: days (1-31).

m: Months (1-12).

d: Days in a week (0 ~ 6, 0 is Sunday).

Task method

Task log

For example, the timing task setting of the homepage of the webpage is as follows

#  Timing task 
CRONJOBS = [
  #  Every 5 Execute in minutes 1 Second generation of home page static file 
  ('*/5 * * * *', ' Execute functions that generate static pages ', '>>  The path to generate the log ')
]

Solve the problem of Chinese characters

In a timed task, if a non-English character appears, a character exception error will occur

You can do this by adding additional commands to the configuration file for timed task execution

#  Solve crontab Chinese problem 
CRONTAB_COMMAND_PREFIX = 'LANG_ALL=zh_cn.UTF-8'

Start Timing Task

Adding Timing Tasks to the System

python manage.py crontab add

Displays active timed tasks

python manage.py crontab show

Remove Timed Task

python manage.py crontab remove

When the timer task is turned on, an log log appears in the log log every 5 minutes
