从日期范围中获取数据

Question

我希望看到我的room_requests期限包含在我的日期范围内。这就是我所做的：

此视图的控制器：

def not_confirmed_slots
  if params[:search] 
    @slots = RoomRequest.find(:all, :conditions => ['date >= ? and date =< ?', params[:start_date].strftime("%Y-%m-%d"), params[:end_date].strftime("%Y-%m-%d")]) 
        if @projects.size.zero? 
          flash[:notice] = "No result found" 
          @slots = RoomRequest.find(:all) 
        end 
  else 
    @slots = RoomRequest.all
  end
end

和我的表单来自视图：

%h1= t('headers.reports.notConfirmedSlots')
  = form_tag not_confirmed_slots_reports_path, method: 'get' do
    %p
      = text_field_tag :start_date, nil,  :class => "datepicker", :placeholder => t('placeholders.reports.startDate')
    %p
      = text_field_tag :end_date, nil, :class=>"datepicker", :placeholder => t('placeholders.reports.endDate')
    .clear
       .action_bar
          = submit_tag t('buttons.reports.generate'), {class: "button blue"}

但是每次我提交带有日期的表单时，它都会列出db中的所有room_requests - 任何提示？

哦，这是部分的（它在同一个视图中是搜索表单）：

%table
  - @slots.each do |s|
    %tr
      %td
        = s.bookers_name
      %td
        = s.request_type
