I want to display this way

<td> check_box="id2" value="true"</td> 

i want too this if one check_box this checked on submit form on rails console puts:

Parameters: {"utf8"=>"✓", "authenticity_token"=>"b3kaOUAgyJHqho70958585SVSv7a1Eo3Yd2z54=", "@search_inactive"=>"30","true"}

Parameters: {"utf8"=>"✓", "authenticity_token"=>"b3kaOUAgyJHqho70958585Sassaffdaaz=", "@search_inactive"=>"29","false"}

My View:

<tr>
<td>
 <%= link_to "Answer", "https://docs.google.com/forms/d/1WdpuW2pD-bqhlSmC77sWb3_nz56NAF-kHSh5--GkLnY/edit", :target => "_blank", :class => "btn_forms_gf" %>
  <td align="center">
  <%= form_for :app_changes, :url => {:controller => :user, :action => :show_search } do |f| %>
  <% @search_inactive.each do |p| %>
  <%= check_box_tag "@search_inactive", {}, p.id %>
  <% end %>
  <%= link_to_function('Disable', "$('form').submit()", :app_changes => @show_search, :class => "btn_save") %>
  <% end %>
  </td>
  </tr>
<% end %>
<% end %>

My Controller to render page with all searchs inactives and actives

     def show_search
       @show_search_active = Search.find_by_sql("select * from search where active is true")
       @show_search_inactive = Search.find_by_sql("select * from search where active is false")
   render('/users/show_search_users', :layout => true)
   end

One way to do it would be to setup your form with both a hidden_field_tag and a checkbox_tag for each checkbox input:

<%= form_for ...%>
  <% @search_inactive.each do |p| %>
    <%= hidden_field_tag "search_inactive[#{p.id}]", false %>
    <%= check_box_tag "search_inactive[#{p.id}]", true %> 
  <% end %>

  <% @search_active.each do |p| %>
    <%= hidden_field_tag "search_active[#{p.id}]", false %>
    <%= check_box_tag "search_active[#{p.id}]", true, true %> # true here to have it checked by default 
  <% end %>
<% end %>

Now when you submit your form the params will look like:

{
  "search_inactive"=>{"2"=>"false", "4"=>"false", "71"=>"false", "72"=>"false", "73"=>"false", "74"=>"false"},
  "search_active"=>{"102"=>"true", "104"=>"true", "171"=>"true", "172"=>"true", "173"=>"true", "174"=>"true"}
}

The extra hidden_field_tag allows the form to submit false when the checkbox is NOT checked. But, if the checkbox is checked by a user in the UI the form will submit true . This is a trick that Rails usually does for you automatically when generating a form , but since you're building out the form yourself you need to include the hidden tag explicitly.
