There are many different web frameworks under Python. Django is the most representative of the heavyweights. Many successful websites and apps are based on Django.
Django is an open source web application framework written in Python.
Django complies with BSD copyrights and was first released in July 2005, and released its first official version 1.0 in September 2008.
Django adopts the software design pattern of MVC, namely model M, view V and controller C.
This chapter introduces you to the processing method of triggering static pages through timed tasks in Django. The specific content is as follows:
Install
pip install django-crontab
Add an app
INSTALLED_APPS = [ ... 'django_crontab', # Timing tasks ... ]
Set the timing time of the task
Set the time to execute in the configuration file
Each timing task is defined in three parts:
Mission time
Basic format:
* * * * *
Time Day Month Week Order
M: Minutes (0-59). Expressed by * or */1 per minute
H: hours (0-23). (0 means 0 points)
D: Day (1-31).
m: Month (1-12).
d: Days within one week (0~6, 0 is Sunday).
Task method
Task log
If the timing task is implemented on the home page, the following
# Timing tasksCRONJOBS = [
# Generate home page static files every 5 minutes ('*/5 * * * *', 'Execute the function that generates static page', '>> Path to generate log')
]
untieDetermine Chinese characters
In a timing task, if non-English characters appear, a character exception error will occur
It can be implemented by adding additional commands for timing tasks to execute in the configuration file.
# Solve crontab Chinese problemCRONTAB_COMMAND_PREFIX = 'LANG_ALL=zh_cn.UTF-8'
Turn on timing tasks
Add timing tasks to the system
python crontab add
Displays activated timing tasks
python crontab show
Remove timing tasks
python crontab remove
After the timing task is enabled, a log log will appear in the log log every five minutes.
