Hello, I am referrign to the cookbook example. 1. How does rails know when I generate the controller and model for Recipe that it needs to read the recipes table? 2. I am using instantRails, how can I change the default MySql localhost to use another MySql on another server 10.10.5.x? 3. Can rails do the things I do currently in PHP and JSP? Like login and exporting to pdf/world 4. How do I validate a field to say it is required? Thanks for the help. Regards, Frank Rocco farocco-PkbjNfxxIARBDgjK7y7TUQ@public.gmane.org
1. the table is based on pluralizing your model. Recipe = recipes table.
This can all be configured through Active Record. As a beginner, I
wouldn''t worry about it yet.
2. InstantRails has a config file that can be modified. However, one
thing at a time... Get comfortable writing rails apps using the built in
server. Then go learn InstantRails... It''s not necessary to learn the
language. Your rails application is going to determine the database you
use, not InstantRails.
3.Yup. You should buy the "Agile Web Development with Rails" book. It
covers login very well and really answers a lot of beginner (and
advanced) questions. Plus you''re supporting the development of Rails
(in
a way).
As for PDF, though I''ve not done it, I know it''s possible and
there are
those on the list who have had much success with it/
4. Validation is easy in Rails.
In your Recipe model (recipe.rb) add this line after the class
declaration: (between ''class Recipe'' and
''end''
validates_presence_of :title
To validate the title field. There''s many other validators like
"validates_numericality_of" and others.
Since you''re doing JSP, you should be pretty comfortable with an API
and
Rails has a great one at http://api.rubyonrails.com/
I hope this helps answer your questions. If you can remember that Rails
is much more than scaffolding and ''magic'', you''ll
start to love it and
you''ll be amazed every single day at what it can help you create.
Good luck!

1. Well, look at the api... It''s a single line of code to associate a
Software model with the "software" table instead of the
"softwares"
table. Remember.... It ASSUMES the plurality for you so you can speed
up development, but you can ALWAYS explicitly tell it what to do.
You''ll find that Rails makes a lot of assumptions, and they''re
actually
really *good* assumptions if you''re developing a new app.
class software < ActiveRecord::Base
set_table_name "software"
set_primary_key "software_id"
set_sequence_name "softwareseq " # default would have been
"project_seq"
end
2. WEBrick, the built-in server that runs on port 3000 is great for
development because it''s self-contained. InstantRails (at least in my
humble opinion) is more for staging your applications to see how they
run on Apache, and maybe even for production. I would use WEBrick for
development, especially if you plan to move your code from a PC to a Mac
and then back again.... There''s no configuration! Just run
script/server
(or on windows, ruby scrip/server) from the root of your rails project.
That said, InstantRails *is* pretty handy if you don''t have Ruby,
Rails,
and mySQL already installed on a machine. But I would definitely still
use WEBrick when you''re developing and then mess with configuring your
apps on Apache or Lighttpd at a later time. It tends to distract you...
Instead of coding rails, you become frustrated with trying to learn
Rails and configure Apache + SCGI + Rails and you cast Rails off as
''too
hard'' (It''s happened to some people I know...)
Good luck!

Frank: I made my own with Eclipse for Windows: http://www.napcs.com/howto/railsonwindows.html Or if you don''t want to build your own, you can use the up-and-coming radrails at www.radrails.org And I hear that TextMate is awesome for the Mac As for tutorials, after you do cookbook, try the ''four days on rails'' or just start buiding your own app. The agile book will cover a much larger app (an online store). -----Original Message----- From: rails-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org [mailto:rails-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Frank Rocco Sent: Thursday, December 01, 2005 12:04 PM To: rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org Subject: RE: [Rails] newbie - a few questions Again, thanks for your help.

See the movie [3] of the combination in action. (The movie shows an older version of Locomotive, but should be convincing.) regards Justin [1] http://locomotive.sourceforge.net/ [2] http://www.macromates.com/ [3] http://locomotive.sourceforge.net/images/locomotive_intro.mov

I have got instantrails "working". I am not sure if this is the write forum to ask this, so excuse me if it isn''t. Once I have imported the cookbook example into RadRails, I start the server, and it stays on ''Starting'' state. Although the apache piece is working fine, I can''t seem to figure how to put break points or get it show anything on the server console. Any ideas or tutorials ?
