What's need i put in 'dub0', is it a general id name (used to format html?)?
Strictly speaking you don't need anything. However it's nice to put
the url/url parameters such that if javascript is not available the
submit will go the the right place
What's need i put in 'dub1' and 'dub2', is it the id of text_field
and ...?
'dub1' should be the name of an instance variable and dub2 a method on
that object. The text field's initial value will be @dub1.dub2. I'd
guess you actually want text_field_tag, not text_field
What's need i put in 'dub3', is it ...?
Simple answer: look in development.log at the parameters that are
passed.
