Strange ActiveRecord::AssociationTypeMismatch

Question

I am getting a very strange error when running a spec:

Failure/Error: entity = Factory.create(:entity, :name => \"Test Entity\", :creator => user)
 ActiveR         


        

Answer 1

The issue for me was in my factory definition where I was using additional factories to populate id fields. I accidentally referred to an attribute that didn't exist on the table (account, instead of account_id). See example below.

factory Omni::CustomerAccount do
  sequence(:display_name) {|n| "test #{n}"}
  customer_id :customer  # this is correct
  account :account  # wrong - this should say account_id :account
end

Hope this helps someone.
