Rails Join Tables

Wow,

Bad morning. Took me 30 min to find out that the reason I was throwing an error on a controler was not due to bad code, but due to a bad migration that I wrote.

When writing the join table migration I neglected to specify that there was no primary key. Oracle HATES this.

  def self.up
    drop_table :email_blasts_users
    create_table :email_blasts_users, :id => false do |j|
      j.references :email_blast
      j.references :user
    end
  end

Make sure to have that :id => false if you don't want your database to yell at you.
