yii Postgres错误：列“id”中的值为空-插入操作期间

我使用postgresql和yii 2框架。我得到了一个非常有趣的错误消息：

SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "id" violates not-null constraint
DETAIL: Failing row contains (null, 1, null, null, null, null, 1, Demo, , , , 1998-01-01, , , , 345345435453453, , , , , 1, , , f, f, f, f, 10, f, 1, f, f, f, null, null, null, 1470477479, 1470477479, null).

但是我检查了我的插入命令，那里没有“id”列！

INSERT INTO "advertiser" ("languages", "type", "name", "display_name", "title", "about", "birthday", "gender", "country_id", "county_id", "city_id", "city_part", "street", "house_number", "phone", "public_email", "public_url", "motto", "message", "im_facebook", "im_skype", "has_viber", "has_whatsapp", "has_sms_response", "visible_birthday", "is_checked", "status", "version", "user_id", "created_at", "updated_at") VALUES (NULL, 1, 'Demo', '', '', '', '1998-01-01', 1, NULL, NULL, NULL, '', '', '', '345345435453453', '', '', '', '', '', '', FALSE, FALSE, FALSE, FALSE, FALSE, 10, NULL, 1, 1470477479, 1470477479) RETURNING "id"

所以我真的不能理解这个错误信息。我没有发现Postgres或Yii试图插入一个空ID值或什么。
顺便说一句，你可以在这里找到

你的建议是什么？我应该在哪里寻找问题？

您没有为id插入一个值。因为您没有显式地设置它，所以它被隐式地赋予了一个null值，当然，这个值对于主键列来说是无效的。您可以通过将该列定义为serial而不是普通的integer来避免这种情况，并将所有繁重的工作留给数据库来完成。

serial保留字会在剖析时间展开，之后便无法看见。
Postgresql 10版本中有以下替代项：

id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY

它应该符合SQL标准，因此与Oracle兼容。
有关详细信息，请参阅此blog。

在我阅读一个PostgreSQL 10转储到9.6数据库服务器后发生了这种情况。在那之后，自动创建序列ID的序列丢失了。
这可以如下所示（在psql中）：

SELECT  column_name
,       column_default
FROM    information_schema.columns
WHERE   table_name = 'django_migrations'
ORDER BY 
    ordinal_position;

其中，django_migrations是表名。它应显示如下内容：

column_name |                column_default                 
-------------+-----------------------------------------------
 id          | nextval('django_migrations_id_seq'::regclass)
[...]

如果'column_default'中的值为空，则序列将丢失。

将您现有的主键更改为serial。请阅读以下内容了解如何更改主键

如果您因为客户端、管理、数据库权限等原因而无法更改为serial ...
数据库可能正在使用sequence。
以下是您需要了解的信息：SELECT nextval('seq_nuu_filtreelement')
