呼叫图片已弃用 [英] Calling image is deprecated

问题描述

我刚刚在日志中注意到了这一点(访问 www.sk8whls.com 的主页时):

I just noticed this in my logs (when visiting my homepage on www.sk8whls.com):

从模板"teasers/wheels.twig"中调用模板"macros/html.twig"上的"image"从1.28版开始已弃用，2.0版不再支持.

Calling "image" on template "macros/html.twig" from template "teasers/wheels.twig" is deprecated since version 1.28 and won't be supported anymore in 2.0.

像这样的图像被称为(在预告片/wheels.twig中):

An image is called like this (in teasers/wheels.twig):

{{ html.image( image, 'thumbnail', fallback ) }}

我的宏如下:

{% macro image(image, size, fallback, alt, title, class ) %}
    {% set image    = image %}
    {% set size     = size|default('') %}
    {% set fallback = fallback|default(0) %}

    {% if image and image.src %}
        <img src="{{ image.src(size) }}" alt="{% if alt %}{{ alt }}{% else %}{{ image.alt }}{% endif %}" title="{{ title }}" class="{{ class }}" />
    {% elseif fallback %}
        <img src="{{ fallback }}" alt="fallback" title="" />
    {% endif %}
{% endmacro %}

我不确定为什么不赞成使用它，以及当v2.0支持消失时如何使它继续工作.

I'm not sure why it's deprecated and how I can keep it working when the support drops with v2.0.

推荐答案

从

从Twig 2.0开始，文件中导入的宏在子级中不可用不再使用模板(例如通过包含调用).你需要在您使用宏的每个文件中显式导入宏.

As of Twig 2.0, macros imported in a file are not available in child templates anymore (via an include call for instance). You need to import macros explicitly in each file where you are using them.

这意味着您还应该在 wheels.twig
