选中时通过多项选择（复选框）进行搜查

Question

在我的代码中没有显示错误，我正在使用 Ransak 搜索，但我没有得到搜索输出。当我从复选框中检查大小选项时，我想获得输出。如果我点击中号，我想显示所有中号连衣裙，就像所有 请给我一个解决方案

这是我的复选框

这是我的代码

产品/index.html.slim

= search_form_for @product_search, url: shop_index_path do |f| = f.label :size_cont, "Size Available" - StandardSize.all.each do |s| = check_box_tag('product_search[standard_sizes_id_eq_any_cont][]', s.id ) = s.name

这里是我的 ShopController.rb

class ShopController < ApplicationController def index @product_search = Product.ransack(params[:q]) @products = @product_search.result(distinct:true).page(params[:page]).per(8) @product_search.build_sort if @product_search.sorts.empty? end

模型标准尺寸.rb

class StandardSize < ActiveRecord::Base belongs_to :product end

这是我的模特product.rb

class Product < ActiveRecord::Base has_and_belongs_to_many :standard_sizes end

这是我的服务器 Started GET "/shop?utf8=%E2%9C%93&q%5Bname_cont%5D=dress&q%5Bprice_paisas_gteq%5D=&q%5Bprice_paisas_lteq%5D=&product_search%5Bstandard_sizes_id_eq_all%5D%5B%5D=3&commit=Search" for 10.0.2.2 at 2015-07-23 10:12:42 +0000 Cannot render console from 10.0.2.2!

Answer 1

除非您已另外配置 Ransack，否则所有搜索参数都应嵌套在 @q 下。我也使用_in 而不是_eq_any_cont 取得了成功。

替换

= search_form_for @product_search, url: shop_index_path do |f|
  = f.label :size_cont, "Size Available"
  - StandardSize.all.each do |s|
    = check_box_tag('product_search[standard_sizes_id_eq_any_cont][]', s.id ) 
    = s.name

与

= search_form_for @q, url: shop_index_path do |f|
  = f.label :size_cont, "Size Available"
  - StandardSize.all.each do |s|
    = f.check_box :standard_sizes_id_in, {multiple: true}, s.id, nil
    = s.name
