Following the instructions to the letter, everything worked until I started fooling around with the html.erb files.

When I look in the database, I can see the author_id field in the books table (it is empty for all records). When I restart the server, the changes made in the erb files do not appear.

My original erb files looked like (just one part):

<%= f.label :description %>

<%= f.text_area :description %>

I added a new section that looked like:

<%= f.label :author %>

<%= collection_select(:book, :author_id, Author.find(:all, rder => “name”) , :id, :name) %>

Nothing happened = I still see the old form (with two entry boxes, no author pick list). Flushed cache, restarted browser, restarted server. Nothing changes.

I changed the entire file to match the one in the tutorial. Still nothing changes.

Going out on a limb I tried changing the page title to:

New Improved Book Entry Page

Still nothing. Any hints apart from suggesting a brick wall to bang my head against?

Thanks.

Btw, i tried to introduce the very basics of (M)VC structure in PHP to some wider range of HTML developers by writing my own tutorial about it. Not sure if it’s a good place to share, but hope some1 would find it interesting as well http://blog.thepixers.com/2008/07/tutorial-micro-cms-for-htmlcss-developers/

Cheers, keep up the good work!

Your tutorials are excellent. I’d like to make a request regarding this one, Rails Relationships. I will be working with an existing database where all tables, constraints, and relationships are defined in the DBMS as opposed to using Rails Migrations. I (and I’m sure others) would appreciate any additional info you may have regarding best practices in building Ruby/Rails 2.x applications using legacy databases. The only thing I’ve found so far is this wiki,

http://wiki.rubyonrails.com/rails/pages/HowToUseLegacySchemas

which isn’t all that helpful in practice.

Thanks for your consideration

Great series of tutorials!

I found this slight error in your section called “Rails Associations.”

You have:
Open up your model/book.rb and model/author.rb and add the following lines of code:

# in model/author.rb
^^^^^^^^^^^^^^^^^^^^
class Book < ActiveRecord::Base
belongs_to :author
end

# in model/author.rb
class Author < ActiveRecord::Base
has_many :books
end

But I think the book class’ comment should read:
# in model/book.rb

Hope this makes sense, if it doesn’t drop me an email, and I’ll try to explain it better .

I apologize if I sound technically incorrect. I have been doing RoR for all of 3 days now and had a long break from OOP.

Thanks a lot!
