Django Template block tag

How many different block tag开发者_高级运维s like these exist?

{% block %}

In other words if I have a parent template and child templates with multiple block tags. How does Django know where to insert if not by different block tag names?

Or can I customize like:

{% block_mytag_1 %}

Neither of these will work.

The documentation clearly explains this - you need to give each block in your parent template a different name:

{% block maincontent %}

This will be filled by whatever block in your child template has the same name.

You need this template documentation, particularly the part on Template Inheritance.
