使用 Ransack 一次搜索多个模型 [英] Search multiple models at once with Ransack

问题描述

我的应用标题中有一个搜索表单，我想使用此搜索表单来搜索应用中的多个模型.

I have a search form in the header of my app and I would like to use this search form to search through multiple models within the application.

例如，像 /search?q=rails 这样的请求应该触发对多个模型的搜索，比如 Work、Project、User 及其定义的属性.我想使用 Ransack，因为我已经在应用不同区域的 Work 模型上使用了它.

For example a request like /search?q=rails should trigger a search through multiple models like Work, Project, User and their defined attributes. I wanted to use Ransack because I already use it on the Work model in a different area of the app.

我想我还不太了解 Ransack 并且文档总是指出你必须定义 @q = MyModel.search(params[:q]) 以在表单中使用它search_form_for @q.有没有一种方法可以让您不必提前定义特定模型?只需传入参数名称，如 search_form_for :q?

I think I don't quite understand Ransack yet and the documentation always points out that you have to define @q = MyModel.search(params[:q]) to use it in the form search_form_for @q. Is there a way where you don't have to define a specific model in advance? And just pass in the parameter name like search_form_for :q?

推荐答案

好吧，问完这个问题我的脑子里就蹦出来了.

Okay, after asking the question the answer popped into my head.

代替 search_form_for 助手，我现在只是通过以下方式使用 form_tag 助手:

Instead of the search_form_for helper I'm now just using the form_tag helper in the following way:

<%= form_tag search_path, method: :get do %>
  <%= text_field_tag :q, nil %>
<%= end %>

在搜索操作中我只做:

q = params[:q]
@works    = Work.search(name_cont: q).result
@projects = Project.search(name_cont: q).result
@users    = User.search(name_cont: q).result

这对我有用.我希望这也能帮助其他人.

This works for me. I hope this also helps someone else.
