More than one check boxes and selecting all the check boxes

Hai
Just started to learn Ruby on Rails
I have a list of users displayed as rows and towards each row there is a
check box. There is a "Select All" , and "Approve" buttons. On clicking
the Select All button I want to check all the check boxes or can check
the boxes separtely if don't want to check all the boxes and then after
submitting the Approve button wish to change the status of the
selecteds
users(which users whose check box is checked) to approved. Pls give me
suggestions in doing this.

<table width="100%" border="1">
<tr><td colspan="6" align="center"><h3>User list</h3></td>
</tr>
  <tr>
    <th>Name</th>
    <th>User Name</th>
    <th>Address</th>
    <th> Country</th>
    <th>Language</th>

    <th> <%= submit_tag "Select All", :onclick=>"return check_all()" %>
</th>

  </tr>
  <% count = 0 %>
<%= form_tag :controller=>"user",:action=>"list_users"%>
<% for user in @users %>
<% count = count + 1%>
  <tr>
    <td align="center"><%=link_to
user.name,:controller=>"User",:action=>"edit", :id=>user.id %></td>
    <td align="center"><%= user.username %></td>
    <td align="center"><%= user.address %></td>
    <td align="center"><%= user.country.name %></td>
    <td align="center"><%= user.language.language %>
    <td> <%= check_box_tag "user_status"+count.to_s,user.id%>
  </tr>
<% end %>
<%= hidden_field_tag "h_id" ,count %>
<tr><td colspan="6" align="center">
<%= will_paginate @users %><br>
<%= submit_tag "Approve", :controller=>"user"
,:action=>"list_users",:class=>"test"%>
</table>

and in my controller I tried this one

def list_users

  if !(params[:search].blank? and params[:country_id].blank?)
      if request.post? and params[:commit] == "Search"
      @users =
User.search(params[:search],params[:country_id],params[:page])
    else

    @users = User.paginate :page=>params[:page],:per_page => 2
  end
  else
     @users = User.paginate :page=>params[:page],:per_page => 2
  end
  if @users.blank?
    flash[:notice] = 'No Records Found.'
  end

    if request.post? and params[:commit] == "Approve"
         params[:user_status].each do |ln|
             @user = User.find(ln)
               @user.update_attribute(:user_status,1)
         end

    end
  end
  Now if selected users separately(not by using the "Select All"
button) the status of the selected users are changing. But the "Select
All" button is not working. ie when clicking on the "Select All" button
only the first one in the list is selecting

and in my javascript i wrote
function check_all() {
var count = document.getElementById('h_id').value;
for(i=1;i<=count;i++){
  document.getElementById('user_status'+i).checked = true
}
return false;
}
Pleas help in solving this problem
Thanks in advance
