Per my PHBs, I'm using
ActiveRecord::Base.primary_key_prefix_type
= :table_name_with_underscore
in my current project.
My problem is that this setting seems to be causing me some issues
with my join model's primary keys.
For example I have these three models:
class User < ActiveRecord::Base
has_many :user_ugroups
has_many :ugroups, :through => :user_ugroups
end
class Ugroup < ActiveRecord::Base
has_many :user_ugroups
has_many :users, :through => :user_ugroups
end
class UserUgroup < ActiveRecord::Base
belongs_to :user
belongs_to :ugroup
end
My migration for the join table looks like this:
def self.up
create_table :user_ugroups, :primary_key => :user_ugroups_id do |t|
t.integer :user_id, :null => false
t.integer :ugroup_id, :null => false
end
end
So when I create a UserUgroup like so:
>> UserUgroup.create!( :user => @gdonald, :ugroup => @admin )
ActiveRecord tries to insert a NULL for the user_ugroups_id field and
then I get this:
ActiveRecord::StatementInvalid: OCIError: ORA-01400: cannot insert
NULL into ("MYPROJDB"."USER_UGROUPS"."USER_UGROUPS_ID"): INSERT INTO
user_ugroups (user_ugroups_id, user_id, ugroup_id) VALUES(NULL, 1, 1)
The migration creates my USER_UGROUPS_SEQ without issue, but then it
doesn't get used.
Any ideas?
