如何使用Ransack使用复选框构建高级搜索？ [英] How build a advanced search with checkbox using Ransack?

问题描述

我如何构建高级搜索此图像的方式：

how I build a advanced search how this image:

我有我的控制器，还很基本：

I have my controller, very basic yet:

def index
    @q = Product.ransack(params[:q])
    @products = @q.result(distinct: true)
  end

有我的观点：

<%= search_form_for @q do |f| %>
  <%= f.label :name_cont, "Name" %>
  <br />
  <%= f.search_field :name_cont %>
  <br />
  <%= f.label :brand, "Brand" %>
  <br />
  <%= f.collection_check_boxes :brand, Product.all, :id, :brand %>
  <br />
  <%= f.label :hd, "HD" %>
  <br />
  <%= f.collection_check_boxes :hd, Product.all, :id, :hd %>
  <br />
  <%= f.label :ram, "RAM" %>
  <br />
  <%= f.collection_check_boxes :ram, Product.all, :id, :ram %>
  <br />
  <%= f.submit "Search" %>
<% end %>

但是，唯一可用于搜索的是输入名称。我有两个问题。 1º复选框无效。 2º一些复选框正在重复执行，因为我将Product.all放进去了，但是也放得截然不同，但是没有用= /
您能帮我吗？

But, the only thing that worked on search is the input name. And I have two problems. 1º The checkboxes don't worked. 2º Some checkboxes is repeting because I put Product.all, but too put distinct, but nothing worked =/ Can you help me please?

推荐答案

您可以尝试关注品牌，高清和公羊

you can try following for brand, hd and ram

<% Product.pluck('distinct brand').each do |brand| %>
 <%= check_box_tag('q[brand_cont_any][]', brand ) %>
 <%= brand %>
<% end %>
