data = { :users => [{:id=>1},{:id=>2}] }
payload = {users: "{% for user in users %} {{ user.id }} {% endfor %}" }
@template = Liquid::Template.parse(payload.to_json)
@payload = @template.render(data.deep_stringify_keys)
JSON.parse(@payload) # => {"users"=>" 1 2 "}
可以看到最后输出是 {"users"=>" 1 2 "} ，如何返回 {"users"=>[1,2]} 这种格式（liquid 语法小白，个人认为需要改动payload格式）
payload = {users: "{% for user in users %} {{ user.id }} {% endfor %}".split(" ").map(&:to_i) }
这样看下行不
对

payload 会提前解释成如下
{:users=>[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}
之前参考了 gem liquid 几篇 issue，都吐槽了对数组的创建不太友好，其中下面几种方式针对 liquid 语法进行修改，只是我没成功 https://github.com/Shopify/liquid/issues/699 https://github.com/Shopify/liquid/issues/1202
