Extension:StructuredDiscussions/zh

The StructuredDiscussions extension provides a discussion and collaboration system for talk pages. ‎本页涵盖了如何安装和管理结构化讨论;‎‎使用它的指南，请参阅‎ 你可以自己在沙盒交谈页面尝试Structured Discussions

This extension was previously known as Flow, and names in some places (like the Git repository) still reflect that.

‎结构化讨论扩展由 Collaboration 维基媒体基金会的协作团队创作. ‎ It is still being maintained to fix bugs, but no substantial development on the extension has been done since 2015, other than a rename to "StructuredDiscussions" in September 2017. ‎未来创作可能会重新开始‎. For more information on the development status of this extension, as well as an overview of its design, see Structured Discussions.

安装后
You also need to run the command "composer update --no-dev" from the command line, on the folder where MediaWiki is installed, even if you don't download from git.

Make sure you follow the full instructions for enabling or disabling StructuredDiscussions, including the scripts mentioned there.

依赖性

 * 必需
 * - for notifications (e.g. replies to your post)
 * It is required to have an object cache. It is recommended that you use memcached for this.  You may encounter problems with Redis currently.
 * - for the templates that are automatically installed (e.g. #time)
 * Required for Special:EnableStructuredDiscussions and to avoid corruption if you change the content model of namespaces (towards or away from StructuredDiscussions) if there are already pages in that namespace.


 * 强烈推荐

This is how WMF wikis are configured, and hence is the most tested configuration by far. If you use MediaWiki-Vagrant, enabling StructuredDiscussions enables Parsoid and sets the format to 'html'.
 * Parsoid for the option to store posts as HTML which improves performance.


 * 可选


 * - if you want to use the opt-in beta feature for user talk.
 * - for human-friendly timestamps such as "3 days ago"
 * - 用于可视编辑器支持
 * bug? if you have the VisualEditor present (e.g. perhaps to provide OOUI),then StructuredDiscussions will attempt to contact Parsoid even if VE is not enabled
 * StructuredDiscussions can integrate with, , and , see
 * StructuredDiscussions will integrate with if you have it installed.
 * - to "Thank" users for their posts
 * - for analytics

验证安装
Visit one of the pages you enabled for StructuredDiscussions (see ) and try adding a topic and editing its header.

升级
The  variable, which enumerated StructuredDiscussions boards, was removed as part of. Before upgrading to 1.26 or later, run the maintenance scripts:

The first script was part of MediaWiki core until version 1.34. From 1.35 onward, it is no longer needed.

配置
Here are some settings you need to make in.

启用或禁用结构化讨论
To enable or disable StructuredDiscussions for a namespace in MediaWiki before 1.35, first run on the affected namespaces (or you can do it on  ). ‎从 1.35 开始，不再需要此问题. E.g. if you are about to enable or disable it on NS_TALK (1) and NS_USER_TALK (3) as shown in the PHP config below:

If mwscript is not configured, replace  with

After the above, set  for particular namespaces. 举个例子：

Do not reassign the global.

To enable it on a single page, use Special:EnableStructuredDiscussions. This requires the flow-create-board right, which can be granted to any group (see Manual:User rights#Changing group permissions).

See for how to turn off all StructuredDiscussions pages on your wiki.

仿形配置
StructuredDiscussions uses the Virtual REST Service to contact a Parsoid or RESTBase service. If your wiki loads the extension, then you've probably already set this up. Look for the following in your :

A single Parsoid server can handle multiple wikis. The Parsoid  setting identifies your wiki configuration to Parsoid. By default it is set to the hostname named by, but you can pick an arbitrary string. Older versions of Parsoid also used a unique "prefix" to identify the server; you may need to list that here as well.

Parsoid must have been configured to match, using a line in Parsoid's  like:

Again, the "domain" property is optional in the Parsoid configuration; it defaults to the hostname used in the  property if not specified. The "prefix" property can also be omitted unless you are running an older version of Parsoid. Make sure the  and   listed in Parsoid's   match what's in your wiki's.

See Parsoid/Setup#Configuration for more details.

“达到最大功能嵌套级别'100'，正在中止”
If you get this error, you need to set, probably in.

“捕获到的异常：Xyz中未实现CAS”
StructuredDiscussions invokes  and some cache implementations including   (APCBagOStuff) don't implement CAS. You probably need to use a different cache, for example install memcached and set.

权限
Users must have the core  permission to perform any write action in StructuredDiscussions. Many wikis only grant this permission to the 'user' (logged-in) group.

StructuredDiscussions defines many actions such as  and   (see the list in ). The permissions vary depending on whether the post is your own and whether it has been moderated. For example, by default users can edit their own posts, but only users in the 'sysop' group have the  permission to edit anyone's post. You can override which groups have which permissions and what permissions are required for each Flow action; see Manual:User rights for an overview of permissions.

迁移现有页面
To migrate a single existing page, use Special:EnableStructuredDiscussions. It will handle archiving of a single page (then enabling StructuredDiscussions) automatically.

The script  automates this namespace conversion and archiving, see Flow/Converting talk pages. It is somewhat WMF-specific, so evaluate its operation and backup your database before running it. Another script  converts LiquidThreads pages and their threads to Flow boards and topics, see Flow/Converting LiquidThreads. Similar caveats apply.

Flow adds a Topic: namespace, see Extension default namespaces. You can visit Special:PrefixIndex/Topic: to see if there are existing pages that conflict with this; if so run the maintenance script.

系统消息
Using the "Source editing" option on StructuredDiscussions boards makes visible the help text. The "uses markup" part is linked through the system message MediaWiki:Flow-wikitext-editor-help-uses-wikitext which makes use of an interwiki link to MediaWiki.org.

In some cases, this interwiki link, instead of pointing to on MediaWiki.org, points to a (usually non-existent) Help:Formatting page on the host Wiki. This can be corrected by changing the interwiki link on MediaWiki:Flow-wikitext-editor-help-uses-wikitext to an external link such as.

故障排除
Not getting Flow as expected? There are different fixes, depending on the source of the problem:

错误的自定义名字空间声明顺序
The Flow declares must go after the declare for a custom namespace. Correct order is:

错误的本机常数
Talk pages in the Main namespace are defined as, not

The correct declaration is:

$wgNamespaceContentModels[NS_TALK] = 'flow-board';

未注册的扩展常数
namespace constant is supposed to be. But that constant does not work in the Flow declare-- you must use the actual number: 107. This works:

$wgNamespaceContentModels[107] = 'flow-board';

It's unknown to this author whether Page_Forms failed to register its constants correctly, or whether all extension must use numbers (not constants) with Flow. See list of some other extension namespace constants.

旧残留物
If you're correctly getting Flow on all talk-pages in a namespace, except for one page in that namespace, there may be remnant junk in the talk page (even if it appears empty). Do the following:


 * 1) Browse to the talk page that won't load Flow, e.g.: Portal_Talk:Welcome
 * 2) Delete the Talk page using the Delete tab.
 * 3) Go to the content page for that talk page, e.g.: Portal:Welcome
 * 4) Click Discuss.
 * 5) You get Flow.

Export and Import
There is maintenance script to export Flow data similar to Manual:DumpBackup.php

- gives some hints about the import.
