Manual:User table/ja

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  in the MediaWiki   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. 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
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.

user_password
user_password は、 と の設定によって 3 通りの形式があります:

The hash of the plain text user password.
 * 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).
 * Since MediaWiki 1.24, if the maintenance script has been used, passwords may also start with ":pbkdf2-legacyA:" or ":pbkdf2-legacyB:" like ":pbkdf2-legacyB:!sha256:10000:128!...".
 * In MediaWiki 1.23 and older, if $wgPasswordSalt is true (default) it is a concatenation of:
 * 文字列 ":B:"
 * A pseudo-random hexadecimal 31-bit salt between 0x0 and 0x7fff ffff (inclusive),
 * コロン文字 (":")
 * The MD5 hash of a concatenation of the salt, a dash ("-"), and the MD5 hash of the password.
 * In MediaWiki 1.23 and older, if $wgPasswordSalt is false, it is a concatenation of:
 * 文字列 ":A:"
 * パスワードの MD5 ハッシュ

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_options
user_options is no longer used as of MediaWiki 1.16. 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.

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
user_tokenは、擬似乱数的に生成された値です. When a user checks "Keep me logged in (for up to 365 days)" the value is stored in a persistent browser cookie  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
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
user_registrationは、利用者が登録したときのタイムスタンプです. 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. 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
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, but see T296035 for the proposed revert)

このフィールドは、 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 hasn't been run. Also, some deletions may not affect it consistently.

user_emailauthenticationtimestamp
v1.4 で除去されました.

user_password_expires
Date when user's password expires; null for no expiration date.
