模块:Effective protection level

模块文档[查看] [编辑] [查看历史] [清除缓存] [跳转到代码]

This module provides a way to retrieve the group required to perform a given action on a page. It currently tests the following criteria:

• 在MediaWiki命名空间：sysop
• 全站/使用者的JavaScript/CSS页：interfaceadmin
• 全站/使用者的JSON页：sysop
• 被保护页面：steward、revisionprotected、sysop、templateeditor或autoconfirmed
• 被连锁保护页面：sysop
• 符合标题黑名单：steward或autoconfirmed
• 移动档案：autoconfirmed
• 移动页面或上传档案：autoconfirmed
• 其余：*

Usage

Warning: This module will use up to 4 expensive parser function calls each time it is ran. It should only be used if the exact effective protection level is necessary. Otherwise, consider using title.protectionLevels instead.

From other modules

To load this module:

local effectiveProtectionLevel = require('Module:Effective protection level')._main

The function accepts two parameters. The first is a string containing the action to check, which must be one of "edit", "create", "move", "upload", or "autoreview". The second is optional, and can either be the name of the page to check, or a title returned from the mw.title functions. If the second parameter is omitted, the page being displayed is the one checked against. The return value is a string containing the name of the group required to perform the given action.

From wikitext

The parameters are the same as when it is called directly.

{{#invoke:Effective protection level|action|title}}
