Preloading data without messing up association when data is loaded the 2nd time.
- by denniss
This is how my model looks like
User
belongs_to :computer
Computer
has_many :user
Users are created when people register for an account on the web site but computers are pre-loaded data that I create in seeds.rb/some .rake file. All is fine and good when the app is first launched and people start registering and get associated with the right computer_id. However, suppose I want to add another computer to the list
Computer.destroy_all
Computer.create({:name => "Akane"})
Computer.create({:name => "Yoda"})
Computer.create({:name => "Mojito"}) #newly added
running the rakefile the second time around will mess up the associations because computer_id in the User table refer to the old id in Computer table. Since I have run the script above, the id keeps incrementing without any regard to the association that user has to it.
Question: Is there a better way for me to pre-load data without screwing up my association? I want to be able to add new Computer without having to destroy the user's table. Destroying the computer table is fine with me and rebuilding it again but the old association that the existing users have must stay intact.
