如何在包含文件中使用宏 [英] How to use macros in a included file

问题描述

view.jinja

  {％extendslayout / defaultlayout.jinja％} 
 {％include（ 'details.jinja'）％} 
  

defaultlayout.jinja

  {％import'elements / macros.jinja'as html％} 
  

但是，我无法在details.jinja中使用宏 html ，而无需重新包含它

解决方案

从你的例子看，就好像你试图导入 macros.jinja ，并使用 作为名为 html 的宏。这是不行的。

宏在jinja文件中定义，名字在那里。

macros.jinja：

  {％macro dostuff（x，y，z）％} 
  {％endmacro％} 
  

然后您可以使用导入标记导入整个文件：

  {％import macros.jinja as macros％} 
  宏，它指向macros.jinja文件。要使用 dostuff 宏，必须调用 macros.dostuff（...）。
 
 
 
您需要在macros.jinja中定义一个名为 html 的宏，将macros.jinja导入为宏，然后用 macros.html（...）来调用。
 
 
有道理吗？
 
view.jinja
{% extends "layout/defaultlayout.jinja" %}
{% include('details.jinja') %}
defaultlayout.jinja
{% import 'elements/macros.jinja' as html %}
But i am not able to use the macro html in details.jinja without reincluding it
解决方案
It looks, from your examples, as if you're trying to import macros.jinja, and use that as a macro called html.  It doesn't work like that.

Macros are defined within a jinja file, with names there.

macros.jinja:
{% macro dostuff(x,y,z) %}
    <a href="{{ x }}" title="{{y}}">{{z}}</a>
{% endmacro %}
and you can then import whole files with the import tag:
{% import macros.jinja as macros %}
so then, in your current namespace, you will have macros, which points to the macros.jinja file.  To use the dostuff macro, you have to call macros.dostuff(...).

You need do define a macro called html inside macros.jinja, import macros.jinja as macros, and then call it with macros.html(...).

Does that make sense?
