Postgres error: null value in column "id" - during insert operation
I use postgresql and yii2 framework. Well I got a very interesting error message:
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).
But I checked my Insert command, and there is not "id" column there!
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"
So I really cannot understand this error message. I do not find that the Postgres or Yii try to insert a null ID value or what.
By the way here you can find the structure

Indexes:

What is your advice? Where should I looking for the problem?
Answer
You aren't inserting a value for id. Since you don't explicitly set it, it's implicitly given a null value, which is, of course, not a valid value for a primary key column. You can avoid this entire situation by defining this column as serial instead of a plain old integer, and leave all the heavy lifting to the database.
