Hi,

This is most likely trivial but I cannot find it anywhere… I have a  
text\_field and a button. I would like to use the input in the  
text\_field as a value to compare against a column in a mySQL database  
that’s not the id (call it ‘name’). How can I do this?

Thanks for any help.

You would have to submit the form and do the comparison in the  
controller. The value for the textfield should come in the params[]  
hash.
