Will, thanks for the comments and fully noted! I'm doing a tutorial
through lynda.com titled "Ruby on Rails Essential Training". The
tutorial is really great, but severely outdated. The tutorial goes
through building all the things scaffold automates first, then after
you've completed all the work, he shows you scaffold. Now, he is going
through the code scaffold creates and customizing it. Really great
besides the out of date syntax.
Have any suggestions on ore up to date ROR tutorials I could dig in?
One thing I think I remember is that in Rails < 2.0 (that is, 1.x, or
many years old) the scaffold command would examine any table that
existed in the database and build a scaffold that used the fields it
found there. In 2.0 they changed this behavior. If your tutorial dates
from the 1.x days, many of the claims it may make about what the
scaffold command will do are now wrong.
Since 2.0 (I think, certainly by now) the scaffold command assumes that
there is no table in the database, and generates a migration to create
the table. But you have to tell it what fields to create.
As for how to learn it, the best way is to just use it. Read the
documentation, try stuff and see what it does. When you get a little
further, look at the generator code to really understand what it does.
Good Luck,
