【问题描述】：

相当新的 Rails 开发人员，并且仍在试图弄清楚事情的去向以及如何连接它们。

我有一个 \'records\' 的数据库，并且正在寻找它们。我找到了 ransack gem，它可以做到这一点，但是我不想将搜索放在索引页面上，我想要一个单独的页面用于搜索和它的结果。

我在记录控制器中创建了一个新操作：

def search
 @q = Record.ransack(params[:q])
 @found_records = @q.result(distinct: true)
end

然后是 search.html.erb 视图，然后是路线：

  resources :records do
match :search, to: \'records#search\', on: :collection, via: [:get, :post]
end

然后是视图本身

<%= search_form_for(
@q,
url: search_records_path,
html: { method: :post }
) do |f| %>
<%= f.label :brief %>
<%= f.search_field :brief %>

<%= f.submit %>
<% end %>


<div id=\"records\">
<% @found_records.each do |record| %>
<%= render record %>
<% end %>
</div>

这运行没有错误，但是当我按下搜索框时，页面只是刷新，没有执行搜索。

我想这是一个路由问题，但现在确定如何设置搜索按钮使用的路由？非常感谢这里的任何建议！

- 编辑日志对我来说看起来不错，这是控制台上记录的内容。

【解决方案1】：

- 更新 - 将搜索更改为“获取”解决了该问题，并确保在不更改 ransack 配置以匹配的情况下使用 @q 而不是自定义名称。
