ruby-on-rails - 在开始日期和结束日期之间搜索记录以进行搜查

Question

嗨，我正在使用ransack + kalendae_assets gem在开始日期和结束日期之间搜索记录
为此，我通过引用使用ransack PREDICATES
https://github.com/ernie/ransack/blob/master/lib/ransack/constants.rb

这是我的代码

<%= search_form_for @search, url: guest_search_rooms_path, html: {:method =>:post} do |f| %>
  <%= f.label :start_date_eq , "Start Date"%>   
  <%= f.text_field :start_date_eq, class: 'release_date' %>     

  <%=f.label :end_date_eq, "End Date" %>   
  <%= f.text_field :end_date_lteq, class: 'release_date' %>     
  <%= f.submit "search" %>
<% end %>

rooms.controller

def guest_search 

  @search = Room.search(params[:q])
  @roome = @search.result(:distinct => true)
  @room= @roome.where("status IS ?", true).order("room_type_id desc")

  #@room = @search.result(:distinct => true)
 end 

但是当我输入开始日期和结束日期时，它不会搜索我该怎么做

您可以将范围与开始日期和结束日期一起使用。然后，您可以获取日期之间的搜索结果。这是您的搜索表单中的示例代码:

<div class="control-group">
    <%= f.label :scrap_date_cont, "Scrap Date", class: 'control-label' %>
    <div class="controls">
      <% if q.scrap_date_cont.blank? %>
    <%= f.text_field :scrap_date_cont, include_blank: true, default: nil, :class => 'datepicker3', :style=>"width:100px;" %> 
      <% elsif !q.scrap_date_cont.blank? %>
      <%= f.text_field :scrap_date_cont, :value => "#{change_date_format_for_edit_page(q.scrap_date_cont)}", :class => 'datepicker3', :style=>"width:100px;" %> 
      <% end %>&nbsp;<%= link_to "Select Range", "#", :id => 'dates' %> 

    </div>
  </div>


     <div class="control-group" id="range" style="display:none" >
        <%= f.label :scrap_date_gteq, "Range", class: 'control-label' %>

        <div class="controls">
          <% if q.scrap_date_gteq.blank? %>
          <%= f.text_field :scrap_date_gteq, include_blank: true, default: nil, :class => 'datepicker1', :style=>"width:100px;" %>
          <% elsif !q.scrap_date_gteq.blank? %>
          <%= f.text_field :scrap_date_gteq, :value => "#{change_date_format_for_edit_page(q.scrap_date_gteq)}", :class => 'datepicker1', :style=>"width:100px;" %> 
          <% end %>

           <% if q.scrap_date_lteq.blank? %>
          <%= f.text_field :scrap_date_lteq, include_blank: true, default: nil, :class => 'datepicker2', :style=>"width:100px;"  %>
           <% elsif !q.scrap_date_lteq.blank? %>
           <%= f.text_field :scrap_date_lteq, :value => "#{change_date_format_for_edit_page(q.scrap_date_lteq)}", :class => 'datepicker2', :style=>"width:100px;" %> 
           <% end %>
        </div>
      </div>

这是 Controller 代码:

params[:q][:scrap_date_cont] = change_date_format(params[:q][:scrap_date_cont]) if !(params[:q][:scrap_date_cont]).blank?
    params[:q][:scrap_date_cont] =  params[:q][:scrap_date_cont].to_date.strftime("%d/%Y/%m") if !(params[:q][:scrap_date_cont]).blank?
    params[:q][:scrap_date_gteq] = change_date_format(params[:q][:scrap_date_gteq]) if !(params[:q][:scrap_date_gteq]).blank?
    params[:q][:scrap_date_gteq] =  params[:q][:scrap_date_gteq].to_date.strftime("%d/%Y/%m") if !(params[:q][:scrap_date_gteq]).blank?
       params[:q][:scrap_date_lteq] = change_date_format(params[:q][:scrap_date_lteq]) if !(params[:q][:scrap_date_lteq]).blank?
     params[:q][:scrap_date_lteq] =  params[:q][:scrap_date_lteq].to_date.strftime("%d/%Y/%m") if !(params[:q][:scrap_date_lteq]).blank? 

辅助程式码:

#Change date format in edit time
 def change_date_format_for_edit_page(date)
    new_date = date.strftime("%m/%d/%Y")
    puts new_date.inspect
    return new_date
  end

脚本 :

$("#dates").click(function () {
  var $that = $(this);
  $("#range").toggle("slow", function() {
    $that.toggleClass("toggled-off");
  });
});

我认为这可能对您有帮助...
