I am not able to create a check box or a button that can check and  
uncheckall the check boxes that i have created. It can be a check box  
or button that checks and unchecks all the check boxes.

\<% i = 0 %\> \<% @hotels.each do |hotel| %\> \<%= check\_box('hotel\_', '', {}, hotel.group\_name+i.to\_s, '') %\> \<% i = i + 1 %\> \<% end %\>

thanks in advance,  
Czar

I think the best way is to use javascript for checking and unchecking  
all. Here is a good example that worked for me when I was doing  
something similar.

also [railscasts.com](http://railscasts.com) has a good screencast on checkboxes you might find  
helpful.
