Hi all,

I’m a new Ruby on Rails user, and I’m trying to make a page with  
several groups of 3 radio buttons. The user chooses one button from  
each group, then clicks the save button, where each selection is  
stored in the database. My question is how I can know which button was  
selected - is there a method like get\_checked\_button, or do I have to  
cycle through each group and see which of the three is checked? If the  
latter is the case, how would I do that?

Thanks!

-Kevin

Hi Kevin,

may somebody know a better way to do this.
