Question

我正在尝试向URL添加第二个参数（并且仍然保留第一个参数）。例如，我有网址/商店？排序=按字母顺序排列，并希望添加参数currency = CAD

%form{action: shops_path(params.merge!({currency: params[:currency]}))}
    .input-group
      = select_tag 'currency', options_for_select({'USA' => 'USD' , 'Canada' => 'CAD'}, params[:currency]), class: 'select2'

在上面的代码中，参数刚刚被替换，例如我得到/ shop？currency = CAD而不是/ shops？sorting =按字母顺序排列＆amp; currency = CAD 我做错了什么？

Answer 1

%form{action: shops_path(sorting: 'alphabetically', currency: 'CAD')}

在向路径助手提供params时，无需合并params哈希！

Answer 2

改为使用hidden_field_tag，

= form_tag shops_path do
  .input-group
    = select_tag 'currency', options_for_select({'USA' => 'USD' , 'Canada' => 'CAD'}, params[:currency]), class: 'select2'
    = hidden_field_tag :sorting, params[:sorting]

希望有所帮助！
