我只是遷移我的應用程序從mysql
到postgres
但是當我嘗試在一個特定的表中插入一條記錄,我得到violates not-null constraint
錯誤:錯誤:在列「ID」空值違反非空約束
ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null, 1, 1, null, null, null, 2016-03-09 09:24:12.841891, 2012-12-31 23:00:00, 2012-12-31 23:00:00, null, null, f, null, f, XYZAssignment, null, null, null, null).
********** Error **********
ERROR: null value in column "id" violates not-null constraint
SQL state: 23502
Detail: Failing row contains (null, 1, 1, null, null, null, 2016-03-09 09:24:12.841891, 2012-12-31 23:00:00, 2012-12-31 23:00:00, null, null, f, null, f, XYZAssignment, null, null, null, null).
當我嘗試使用factory_girl
創造了紀錄:
@assignment = FactoryGirl.create(:assignment)
它建立這個SQL查詢:
INSERT INTO assignments(
id, account_id, l_id, viewed_at, accepted_at, declined_at,
expires_at, created_at, updated_at, decline_reason, decline_reason_text,
promotion, c_checked_at, forwardable, type, f_promo,
c_check_successful, c_check_api_result, c_check_human_result)
VALUES (null, 1, 1, null, null, null, '2016-03-09 09:24:12.841891', '2012-12-31 23:00:00', '2012-12-31 23:00:00', null, null, 'f', null, 'f', 'XYZAssignment', null, null, null, null);
這是分配的出廠:
FactoryGirl.define do
factory :assignment do
expires_at 24.hours.from_now
account
lead
end
end
這是該表說明:
CREATE TABLE assignments(
id serial NOT NULL, account_id integer NOT NULL, l_id integer NOT NULL, viewed_at timestamp without time zone, accepted_at timestamp without time zone, declined_at timestamp without time zone, expires_at timestamp without time zone, created_at timestamp without time zone, updated_at timestamp without time zone, decline_reason character varying(16), decline_reason_text character varying(256), promotion boolean NOT NULL DEFAULT false, c_checked_at timestamp without time zone, forwardable boolean DEFAULT true, type character varying(64), f_promo boolean, c_check_successful boolean, c_check_api_result character varying(32), c_check_human_result character varying(32), CONSTRAINT assignments_pkey PRIMARY KEY (id)
) WITH (
OIDS=FALSE
);
看起來它不能夠自動遞增的ID,任何想法?
從列表中刪除'id'並從值列表中導出'null'。自動增量比直接顯式賦值弱。 – mudasobwa
