I have two models join by a middle model
class Integration < ActiveRecord::Base
has_many :integration_records
has_many :records, through: :integration_records
end
class IntegrationRecord < ActiveRecord::Base
belongs_to :integration
belongs_to :record
end
class Record < ActiveRecord::Base
has_many :integration_records
has_many :integrations, through: :integration_records
end
i = Integration.create(whatever)
i.records.create(whatever)
=> (0.1ms) BEGIN
SQL (8.7ms) INSERT INTO "records" ("created_at", "updated_at") VALUES ($1, $2) RETURNING "id" [["created_at", Sat, 03 May 2014 00:31:02 UTC +00:00], ["updated_at", Sat, 03 May 2014 00:31:02 UTC +00:00]]

Not sure why this is happening, in the case of i.records.create(whatever)
it should output:
SQL (0.6ms) INSERT INTO "records" ("created_at", "updated_at") VALUES ($1, $2) RETURNING "id" [["created_at", Sat, 03 May 2014 00:31:06 UTC +00:00], ["updated_at", Sat, 03 May 2014 00:31:06 UTC +00:00]]
(0.4ms) COMMIT
INSERT INTO "integration_records" ("created_at", "data", "integration_id", "updated_at") VALUES ($1, $2, $3, $4) RETURNING "id" [["created_at", Sat, 03 May 2014 15:57:05 UTC +00:00], ["data", {}], ["integration_id", 5], ["updated_at", Sat, 03 May 2014 15:57:05 UTC +00:00]]
I should note that for some reason, when I create a new app in rails 4.0.4, I still had this problem. But when I change the names of the models and specifically Record
model, it works perfectly fine. So when I changed it to Recordrow
no problem at all.
