Hello there, this is probably a very simple problem but I''m stuck. I''m following the Login generator tutorial from rubyonrails. It''s all worked fine so far. But I want to add a bit more functionality so that when a user signs up in addition to chosing a login name and password they type in a company name which is added to a seperate table called COMPANIES.

I am building an invoicing system but cannot use the auto_increment field to determine the invoice number (because they are running 3 different companies off the one system.

I''m curious, but isn''t this example in the documentation for ActiveRecord::Associations::ClassMethods somewhat counter-intuitive? The SQL DDL is correct for the way it''s used in the models. But isn''t it more logical that an author would have many posts, rather than many authors having one post? From

Hi all, Im slowly moving forward, but there''s something a miss. I can save some relational records to tables, but only once. For an unknown reason, the primary key (id) of the child table is not automatically increased. (I can only perform one save, (the first records id field holds the value ''0'') and during the next save it says: Mysql::Error: Duplicate entry

This is probably a very stupid error on my side, but I am doing my first steps now and I don''t see what is wrong. I have companies and I have users. A user can create a company. When the user does he''s automatically a member of the company. A company should be able to have multiple users off course so every member of a company can add other users who don''t have a

Hello all, I have a spec for a route that used to pass under Rails 2.2.2 and rspec 1.1.12, but can?t figure out what is wrong since I updated. Here is the assertion: route_for( { :controller => ''purchase_orders'', :action => ''update'', :company_id => "32", :id

I have a Merchant class that has many Products. Product is an abstract class which has many subclasses (ProductA, ProductB, etc). All Products have common data, like ''name'', ''status'', ''created_on'', etc... but they also have some completely different properties. It seems like Active Record only supports Single Table Inheritance. This

I''ve got a User model and a Book model. A user is required to submit books each month to be reviewed by other users. I have the following relationships defined: # the join model book_review.rb belongs_to :user belongs_to :book end book.rb # each book is reviewed by many users. This allows us to get the BookReview # objects associated with this book has_many :book_reviews,

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),
