Firstly you will find life much easier if you stick to the rails
conventions, so table names should be plural, lower case with
underscores separating the words, and should match the model class
names which are CamelCase. Column names should be lowercase. I don't
understand what you say about the foreign key. Have you read the
Rails Guide on ActiveRecord Associations (and the other guides for
that matter)? It describes the conventional methods of relating
tables. Also if you are a beginner I suggest working through some
tutorials. Make sure they are Rails 3 tutorials. railstutorial.org
is good and is free to use online.
