Twig无法在字符串变量上调用方法

"twig/twig"更新为"v2.4.4"后,调用宏函数时出错。

Impossible to invoke a method ("widget_prototype") on a string variable (":ERP/timesheets:_form_part.html.twig").

我的宏:

{% macro widget_prototype(widget, remove_text) %}
{% if widget.vars.prototype is defined %}
    {% set form = widget.vars.prototype %}
    {% set name = widget.vars.prototype.vars.name %}
{% else %}
    {% set form = widget %}
    {% set name = widget.vars.full_name %}
{% endif %}

调用宏部分:

{% include ':ERP/timesheets:_data_content_supply_from_widget.html.twig' with {form:form, name:name} %}

{% endmacro %}

            <div id="post_supplies"
             data-prototype="{{ _self.widget_prototype(form.supplies, 'remove'|trans({}, 'common'))|escape }}"
             style="margin-bottom: 5px">
            {% for widget in form.supplies.children %}
                {{ _self.widget_prototype(widget, 'remove'|trans({}, 'common')) }}
            {% endfor %}
        </div>

如何正确调用宏?在没有_self的情况下尝试通话,我收到错误:Unknown "widget_prototype" function.

DarkBee的答案很好,但如果您的宏位于调用它的同一个twig文件中,那么仍然需要像这样导入它:

{% import _self as my_macros %}
{{ my_macros.widget_prototype(...) }}

似乎有点反直觉,但事实就是如此。

您需要导入宏,而不是包含它

{% import "my_macro.twig" as my_macro %}
{{ my_macro.function(arg1) }}
