Definition: in the Django framework, templates are tools that help developers quickly generate pages that are presented to users

The design of the template realizes the decoupling of VT in our MVT. VT has the relationship of NVR M, a V can call any T, and a T can be used by any V.

Template processing is divided into two processes.

① loading

② rendering

The template has two main parts.

① HTML static code

Code snippets dynamically inserted by ② (digging, filling)

In addition to the basic static filling, the dynamic code snippets in the template can also achieve some basic operations, transformations and logic.

Variables in the template: data passed from the view to the template, following the rules for identifiers

Syntax {{var}}

Labels in templat

Syntax {tag}

Action

Load externally incoming variables

Create text in the output

Control loop or logic

{% if expression%} statement {% endif%} {% if expression%} statement {% else%} statement {% endif%} {% if expression%} statement {% elif expression%} statement {% endif%} {% for variable in list%} statement 1 {% empty%} statement 2 {% endfor%}

There are two kinds of template language annotations:

1 single-line comment: {# commented out #}

2 multiline comment

{% comment%}

What is annotated

{% endcomment%}
