Manual:user テーブル
user テーブルには、MediaWiki が利用者についての情報を格納します。 Postgres を使用する場合は、このテーブルの名前は mwuser になります (1.37 未満)。
フィールド
Some of this information was adapted from schema.doc in the MediaWiki docs/ directory.
user_id
user_id は、利用者を一意に特定するために使われる主キーです。
user_name
user_name: 利用者名は一意でなければならず、IPアドレスの形を取ってはなりません。 半角スラッシュや大文字小文字だけの差異を認めてはいけません。 Manual:$wgInvalidUsernameCharacters も参照してください。 半角スペースは認められ、アンダースコアは半角スペースに置換されます。これはページ名における処理と逆です。
user_real_name
| MediaWiki バージョン: | ≧ 1.3 |
user_real_name には、個人設定から設定できる利用者の実名（任意）が格納されます。
This field provides a publicly viewable real name to ?action=credits pages.
Turn this feature off with $wgHiddenPrefs[] = 'realname'; and $wgActions['credits'] = false;
user_password
user_password は、$wgPasswordDefault の設定によって 3 通りの形式があります:
- MediaWiki 1.24 以降、$wgPasswordDefault の既定値は pbkdf2 です。 この場合、以下を連結したものが返ります:
- 文字列 ":pbkdf2:"。
- The hashing algorithm used inside the pbkdf2 layer, by default "sha512".
- コロン文字 (
:)。 - このアルゴリズムのコスト。既定値: "30000"。
- コロン文字 (
:)。 - The length of the derived key; "64" by default.
- コロン文字 (
:)。 - Base64 encoded salt of the hashing algorithm, e.g. "kkdejKlBYFV7+LP2m2thYA=="
- The colon character (
:). - And finally the base64 encoded result of the hashing algorithm (that had a (default) length of 128 bytes before base64 encoding). The hash of the plain text user password.
- Since MediaWiki 1.24, if the maintenance script wrapOldPasswords.php has been used, passwords may also start with ":pbkdf2-legacyA:" or ":pbkdf2-legacyB:" like ":pbkdf2-legacyB:!sha256:10000:128!...".
- For passwords written by MediaWiki 1.23 and older, if $wgPasswordSalt was true (default) it is a concatenation of the following:
- For passwords written by MediaWiki 1.23 and older, if $wgPasswordSalt was false, it is a concatenation of the following:
- 文字列 ":A:"
- パスワードの MD5 ハッシュ。
In wiki farms which use CentralAuth, this field can contain an outdated and unused value (T104500).
The canonical password value is stored in the gu_password field of the globaluser table.
user_newpassword
user_newpassword is generated for the mail-a-new-password feature.
user_newpass_time
user_newpass_time is set to the current timestamp (wfTimestampNow()) when a new password is set. Like the other timestamps, it is in MediaWiki's timestamp format (yyyymmddhhmmss, e.g. 20130824025644).
user_email
Email should be restricted, not public info. Same with passwords. Enter details at your own risk. ;)
This field is not nullable, so users who have never supplied an email address have an empty string set.
In wiki farms which use CentralAuth, this field can contain an outdated and unused value (T104500).
The canonical email is stored in the gu_email field of the globaluser table.
user_touched
user_touched the last time a user logged in (not just mere visiting using an existing session), modified user settings, or got promoted into new user groups.
user_token
| MediaWiki バージョン: | ≧ 1.4 |
user_token は、擬似乱数的に生成された値です。
When a user checks ログイン状態を保持 the value is stored in a persistent browser cookie ${wgCookiePrefix}Token that authenticates the user while being resistant to spoofing.
user_email_authenticated
user_email_authenticated is the timestamp of when the user email was authenticated. 既定値は NULL です。
user_email_token
| MediaWiki バージョン: | ≧ 1.5 |
user_email_token is a token used for confirming an email address. See User::newFromConfirmationCode in User.php
user_email_token_expires
user_email_token_expires is the expiration timestamp of the email token.
user_registration
| MediaWiki バージョン: | ≧ 1.6 |
user_registration は、利用者が登録したときのタイムスタンプ (日時) です。 登録日が古い利用者については、この値がNULLとなる場合があります。 fixUserRegistration.phpスクリプトを使うことで、NULLとなっている登録日を修正することができます。
user_editcount
| MediaWiki バージョン: | ≧ 1.9 |
user_editcount は、利用者が行った編集、および編集に似た操作の大まかな回数です。 以下の操作は編集としてカウントされます。
- Creating or modifying a MediaWiki page even if the revision or page is later deleted (i.e. making a non-null edit)
- Structured Discussions（旧称: "Flow"）の作成や編集
- Moving a page to a new title (since version 1.30)
- The redirect created from a page move (since version 1.38 until T296035 was fixed in version 1.44)
このフィールドは、COUNT(*) FROM revision WHERE rev_user = user_idによる値と正確に等しいわけではありません。
However, it should be roughly accurate if the update scripts are consistently run and it's the only place edit count data is available to the software, so it's still used for serious purposes like deciding whether accounts have been autopromoted.
A number of things could cause this value to be incorrect. For example, it may be out of date or, for old accounts, NULL if the update script (initEditCount.php) hasn't been run. Also, some deletions may not affect it consistently.
user_password_expires
| MediaWiki バージョン: | ≧ 1.23 |
Date when user's password expires; null for no expiration date.
user_is_temp
| MediaWiki バージョン: | ≧ 1.41 Gerrit change 918513 |
A boolean value representing whether the user is a temporary user. Zero if any type of user other than a temporary user. This exists to allow temporary users to be identified from the database only, by external applications. See Help:仮アカウント for more details.
Removed fields
user_emailauthenticationtimestamp
| MediaWiki バージョン: | ≦ 1.3 |
v1.4 で除去されました。
user_options
| MediaWiki バージョン: | ≦ 1.18 |
(1.16 で廃止予定) Manual:user_propertiesテーブル を参照してください。
On older versions of mediawiki, it is a newline-separated list of name=value pairs of the information of Special:Preferences. Old user accounts who haven't logged in since the field stopped being used may still have this field set.
