Flask-Moment ---- exploration,

　Preface:Flask-Moment is relatively simple in all flask extensions, but there are still many things to understand. let's take a look at the application of flask-moment in the flask project.

　　

First of all, we need to understand what flask-moment is for, and extract a paragraph from the dog book:

　　　　　　　There is an excellent open-source client code library developed using JavaScript, named moment. js (http: // momentjs.
Com/), which can render the date and time in the browser. Flask-Moment is a Flask program extension that can
Moment. js is integrated into the Jinja2 template.

This section is easy to understand. Simply put, the time is displayed on the webpage. The specific operations are as follows:

 

　　　1. initialize flask-moment　　　　　

　　　from flask_sqlalchemy import SQLAlchemy　　　moment=Moment()

 

2. conditions required for applying flask-moment　　　

　　　　{{ moment.include_moment() }}　　　　{{ moment.include_jquery() }}

Import moment and jquery. If bootstrap is applied to your project, you do not need to import jquery.

The two-line code can be stored in the base.html style to facilitate inheritance of Other templates.

 

Iii. Actual Practice

# Import from datetime import datetime time = datetime. utcnow () # pass as a parameter of the view Function

　　　　

　　
<P> the page is opened at {moment (time ). format ('yyyy-M-D, H: mm: ss A, week w ')}}. </p> <p> past: {moment (time ). fromNow (refresh = True) }}</p>

How can this problem be understood?

　　　Moment (time). format ('yyyy-mm-dd, H: mm: ss A, week w ')

# Obtain the current time and display it at a certain time

　Moment (time). fromNow (refresh = True)

# FromNow indicates the relative time, which indicates how long the last time has elapsed. When refresh = True is passed, the time will be displayed on the page, for example, several seconds or minutes.

　　　

I have questions at the beginning, huh? YYYY-mmonth... what are these things? I didn't explain it clearly. In fact, if you have good English, you can understand year very well!

The details are as follows:

YYYY	2014	Year
YY	14	The year in two characters.
Q	1..4	Quarter
M MM	4..04	Month
MMM MMMM	April. April	Displays the month according to the settings in moment. locale ().
D DD	1..31	The day of January 1, January
Do	1 .. 31	The day of January 1, January
DDD DDDD	1..365	Day of the year
X	1410715640.579	Timestamp
x	1410715640579	Timestamp

 

Of course there are many moment. js methods, specific visit moment. js Chinese official website: http://momentjs.cn/
