ruby-on-rails - 通过检查时的多个选择(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，喜欢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

这是我的模型 product.rb

class Product < ActiveRecord::Base
has_and_belongs_to_many :standard_sizes
end

这是我的服务器正在获取

除非您以其他方式配置 Ransack，否则所有搜索参数都应嵌套在 @q 下。我也用 _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
