Hi Everyone, I built a scaffold and I''m having trouble getting results properly formatted. (I need to get the data into multiple columns instead of just one big column) I can''t get all of my CSS to work properly in scaffold.css, layout/books.rhtml, or the books/index.rhtml.erb Anyways, maybe you have a suggestion. Default view (127.0.0.1:3000/books) Title Abstract Book One Book One Abstract Show Edit Destroy Book Two Book Two Abstract Show Edit Destroy Book Three Book Three Abstrac...

This is a bit of a long question, but to those of you with some experience, it should be fairly simple I think. I have a notes page that should list all notes the user has entered for all books chronologically like this. Book One: This is the note. Book Four: This is the note. Book One: A different note, entered later. Right now my models are: User has_many :books Book has_many :notes belongs_to :user Note (has column book_id) belongs_to :book has_one :book The Not...

I keep getting this exception "SQLite3::SQLException: no such column: books.user_id: SELECT "books".* FROM "books" WHERE ("books".user_id = 4)" ,which sounds like there is no user_id in books table.So i just installed foreigner plugin and added " t.integer :user_id, :null => false" and "add_foreign_key(:books, :users)&q...

I tried to validate the information this way: validates_presence_of :school_type, :if => Proc.new { |c| !c.booking.nil? and ( c.booking.camp.camptype == Camptype.find(:first, :conditions => [ ''name = ?'', "Children''s Camp"]) or c.booking.camp.camptype == Camptype.find(:first, :conditions => [ ''name = ?'', ''Adventure Camp'']) ) } vali...

People, In the cookbook eg, categories has_many recipes but in a book eg, book has_one description - doesn''t that mean that the id of the description should be the same as the id of the book (instead of having it''s own "description_id" in the book table? Thanks, Phil. -- Philip Rhoades Pric...

I''ve got a question on the use of check_box. *** This is working but there just has to be a better way: RHTML: <% for book in @books do %> <tr> <td><%=book.label%></td> <td> <%checked = book.subscribed ? ''checked'': ''nope''%> <%=check_box("book" + book.id.to_s, ''checked'', :checked => checked)...

This post addresses URLs generated by Ruby on Rails from a human factors point of view. Allow me to use Hieraki as an example. Hieraki is a great application. It was one of my first introductions to the power of Ruby on Rails. Scenario: When I navigated to Chapter 1 of a book the URL in my address bar was http://www.library.com/read/chapter/6. This inconsistancy ("Am I on Chapter 1 or 6?") threw me for a loop. I navigated back to the book page (http://www.library.com/read/book/2) to check the link again. With reduced confidence, I reclicked the "Chapter...

Assuming we have the trivial model of class Author has_many :books end class Book end How do people go about creating the authors/edit and authors/new views if you want to be able to add and remove arbitrary amount of Books at Author creation and edit time? What I mean by this is that I go to ''authors/new'' then add a few Books and then c...

hello, On page 49 of the beta version of Ruby on Rails: Up and Running, the book suggests to download a zip file containing everything that has been done up to that point, and a create_tables_with_data.sql file. The book doesn''t have the link, and I couldn''t find it in the book site. Does anyone know where to get the files? This is a very good book. Thank...

People, I have gone through the cookbook example: http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=1 and everything worked fine an a FC4/Postgres setup.
