This is probably a stupid question but I am confused…
I see an example in the 3d Edition of Agile Dev with Rails (page 539)
where a simple calculator view, with two text boxes for numbers and a
dropdown for what operation to perform, does not mention a submit button
I don’t understand that. Yes, the form_tag does indicate an :action => ,
but what triggers that if there is no <%= submit_tag ‘Save’ %>?
