我對django製作的postgresql數據庫表感到困惑。我從psql命令獲得了有關我的用戶表的信息。第一個colmun，它是last_login字段。但是我不會在任何地方設置last_login字段。Django數據庫模型
表定義如下。
remoshin_devdb=# \d remosys_remoshin_user_tbl;
Table "public.remosys_remoshin_user_tbl"
Column | Type | Modifiers
-----------------+--------------------------+-----------
last_login | timestamp with time zone |
userid | character varying(64) | not null
username | character varying(128) | not null
email | character varying(254) | not null
password | character varying(128) | not null
usertype | character varying(1) | not null
is_active | character varying(1) | not null
is_admin | character varying(1) | not null
u_kana_name | character varying(128) |
u_date_of_birth | date |
u_gender | character varying(1) | not null
u_postno | character varying(7) |
u_address1 | character varying(128) |
u_address2 | character varying(128) |
u_telno | character varying(16) |
u_photo | character varying(100) |
d_photo | character varying(100) |
create_date | timestamp with time zone | not null
modify_date | timestamp with time zone | not null
d_clinic_id_id | character varying(8) |

而我的用戶模型如下。我不使用last_login字段。我不明白髮生了什麼事。請給我一個建議。

謝謝你的回覆。這對我很有幫助。 –
