您可以在包含的文件中使用宏，但是可以使用上下文导入宏，而不要包含它。
T1.html
<root>
<block t3_container>
{% block t3 %}{% endblock %}
</block t3_container>
<block t2_container>
{% block t2 %}{% endblock %}
</block t2_container>
</root>
T2.html
{% extends 'T1.html' %}
{%- from 'T3.html' import inner, inner2 with context %}
{% block t3 %}
{{ inner2() }}
{% endblock %}
{% block t2 %}
<block t2>
{{ inner() }}
</block t2>
{% endblock %}
T3.html
{% macro inner2() %}
<block t3>
CONTENT '{{ foo+1 }}'
</block t3>
{% endmacro %}
{% macro inner() %}
