Django Template Inheritance--20180123

A.include Template Tags

B.extend (inheritance) template label

-- include template label

This tag allows the content of other templates to be included in the (template). The parameter of the label is the name of the template to be included, either a variable or a hard-coded string in single/double quotation marks. Whenever the same code appears in multiple templates, you should consider whether you want to use {% include%} to reduce duplication.

------extend (inheritance) template label

You first construct an underlying framework template and then overload it with the common parts of the site and the definition blocks in its child templates.

Attention:
We can get the contents of the parent class by {% Block.super%}
<1> Create a base.html template in which to define the main visual feel of the site. These are parts that are infrequently modified or even never modified.
<2> Create base_section.html templates for each area of the site these templates extend the base.html and include area-specific styles and designs.
<3> create separate templates for each type of page, such as forum pages or photo galleries. These templates extend the appropriate area templates.
