I want to create a check box that will update a field in a database  
table. How do you link a method in a model to a check box?

Do you mean updates the record via Ajax when the check box is clicked?

Yes, you can use the observer\_field helper method  
([http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000535](http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000535))

Hope this helps

I tried that in a form, and it didn’t work, is there any way to force it  
to do execute the method.

Also, I like the idea of automatically updating with ajax, is there a  
way to do this without UJS?
