如何在Liquid中的for循环中创建数组? [英] How to create an array in a for loop in Liquid?

问题描述

我正在尝试使用Liquid语法从对象列表中创建一个数组:

I'm trying to create an array from a list of objects using Liquid syntax:

{% for operation in menuItems %}
      {% assign words1 = operation.Title | split: '_' %}
      {% assign controllerName = words1 | first %}
      {% assign controllersTmp = controllersTmp | append: '_' | append: controllerName %}
{% endfor %}

我想分割controllersTmp以获得数组，但是此时我的controllersTmp为空.

I want to split the controllersTmp to get my array, but at this point my controllersTmp is empty.

有帮助吗?

推荐答案

您可以直接创建一个新的空数组controllers和

You can directly create a new empty array controllers and concat to it your controllerName converted into an array using the workaround split:''. The result is directly an array, without the extra string manipulations.

{% assign controllers = '' | split: '' %}
{% for operation in menuItems %}
    {% assign controllerName = operation.Title | split: '_' | first | split: '' %}
    {% assign controllers = controllers | concat: controllerName %}
{% endfor %}
