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.

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

```

 \<% count = 0 %\> \<%= form\_tag :controller=\>"user",:action=\>"list\_users"%\> \<% for user in @users %\> \<% count = count + 1%\> \<% end %\> \<%= hidden\_field\_tag "h\_id" ,count %\>

| 
### User list
 |
| Name | User Name | Address | Country | Language |
| --- | --- | --- | --- | --- |
| \<%=link\_to user.name,:controller=\>"User",:action=\>"edit", :id=\>user.id %\> | \<%= user.username %\> | \<%= user.address %\> | \<%= user.country.name %\> | \<%= user.language.language %\> | \<%= check\_box\_tag "user\_status"+count.to\_s,user.id%\> |
| \<%= will\_paginate @users %\>  
\<%= submit\_tag "Approve", :controller=\>"user" ,:action=\>"list\_users",:class=\>"test"%\> |

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
