Extension:StructuredDiscussions/hi
 | Structured Discussions is no longer in feature development, and new deployments have been suspended. See more information in the Wikitech mailing list. |
| This extension is currently not actively maintained! Although it may still work, any bug reports or feature requests will more than likely be ignored. If you are interested in taking on the task of developing and maintaining this extension, you can request repository ownership. As a courtesy, you may want to contact the author. You should also remove this template and list yourself as maintaining the extension in the page's {{Extension}} infobox. |
The StructuredDiscussions extension provides a discussion and collaboration system for talk pages. This page covers how to install and administer Structured Discussions; for a guide to using it, see Help:Structured Discussions. You can try out Structured Discussions yourself at the Sandbox talk page.
This extension was previously known as Flow, and names in some places (like the Git repository) still reflect that.
The StructuredDiscussions extension was developed by the Collaboration team at the Wikimedia Foundation. 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. For more information on the development status of this extension, as well as an overview of its design, see Structured Discussions.
 चेतावनी: | This extension is currently incompatible with temporary accounts. |
Installing
 सावधान: | Note that StructuredDiscussions is not compatible with SQLite. |
- Make sure that all required dependencies are set up and configured.
- Make sure to set
$wgVirtualRestConfig['modules']['parsoid']['url']to point to the rest.php of your wiki. - If you have problems in MediaWiki 1.40, you should make some changes to remove virtualrestconfig of restbase in Flow. See task T337223.

Post install
/tmp/mw-UIDGeneratorUUID-UID-xx files that MediaWiki may be unable to open (टास्क T55791). If you get a "Permission denied" error upon first visiting a Flow board you have to delete these files. Also, update.php will create {{FlowMention}} to support Flow's mention feature in VE (either @ or a toolbar menu provides a convenient auto-complete interface for mentions).Make sure you follow the full instructions for enabling or disabling StructuredDiscussions, including the scripts mentioned there.
निर्भरता
- required
- Extension:Echo - 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.
- Extension:ParserFunctions - for the templates that are automatically installed (e.g. #time)
- strongly recommended
- Parsoid for the option to store posts as HTML (
$wgFlowContentFormat = 'html';) which improves performance.
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'.
- optional
- Extension:BetaFeatures - if you want to use the opt-in beta feature for user talk.
- Extension:CLDR - for human-friendly timestamps such as "3 days ago"
- Extension:VisualEditor - for VisualEditor support
- 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 Extension:दुरुपयोग फ़िल्टर, Extension:SpamBlacklist, and Extension:ConfirmEdit, see Extension:StructuredDiscussions/Spam
- StructuredDiscussions will integrate with Extension:CheckUser if you have it installed.
- Extension:Thanks - to "Thank" users for their posts
Verifying installation
Visit one of the pages you enabled for StructuredDiscussions (see #Configuration) and try adding a topic and editing its header.
विन्यास
Here are some settings you need to make in LocalSettings.php.
Enabling or disabling StructuredDiscussions
| मीडियाविकि संस्करण: | ≤ 1.34 |
To enable or disable StructuredDiscussions for a namespace in MediaWiki before 1.35, first run populateContentModel.php on the affected namespaces (or you can do it on all).
From 1.35 onward, this is no longer needed.
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:
mwscript populateContentModel.php --wiki=somewiki --ns=1 --table=revision
mwscript populateContentModel.php --wiki=somewiki --ns=1 --table=archive
mwscript populateContentModel.php --wiki=somewiki --ns=1 --table=page
mwscript populateContentModel.php --wiki=somewiki --ns=3 --table=revision
mwscript populateContentModel.php --wiki=somewiki --ns=3 --table=archive
mwscript populateContentModel.php --wiki=somewiki --ns=3 --table=page
If mwscript is not configured, replace mwscript populateContentModel.php with php maintenance/populateContentModel.php
After the above, set $wgNamespaceContentModels[namespace] for particular namespaces.
For example:
// These lines enable StructuredDiscussions on the "Talk" and "User talk" namespaces
// All the NS_* constants here: https://www.mediawiki.org/wiki/Manual:Namespace_constants
$wgNamespaceContentModels[NS_TALK] = 'flow-board';
$wgNamespacesWithSubpages[NS_TALK] = true;
$wgNamespaceContentModels[NS_USER_TALK] = 'flow-board';
$wgNamespacesWithSubpages[NS_USER_TALK] = true;
Do not reassign the global ($wgNamespaceContentModels =
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).
$wgGroupPermissions['somegroup']['flow-create-board'] = true;
See Extension:StructuredDiscussions/Turning off all StructuredDiscussions for how to turn off all StructuredDiscussions pages on your wiki.
Parsoid configuration
 | इस पृष्ठ के कुछ हिस्से (जिनके संबंध का विषय है Parsoid's LocalSettings.js) कालग्रस्त हैं। |
StructuredDiscussions uses the Virtual REST Service to contact a Parsoid or RESTBase service.
If your wiki loads the VisualEditor extension, then you've probably already set this up.
Look for the following in your LocalSettings.php:
$wgVirtualRestConfig['modules']['parsoid'] = array(
// URL to the Parsoid instance
// Use port 8142 if you use the Debian package
'url' => 'http://localhost:8000',
// Parsoid "domain", see below (optional)
'domain' => 'localhost',
// Parsoid "prefix", see below (optional)
'prefix' => 'localhost',
);
A single Parsoid server can handle multiple wikis.
The Parsoid domain setting identifies your wiki configuration to Parsoid.
By default it is set to the hostname named by $wgCanonicalServer, 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 localsettings.js like:
parsoidConfig.setMwApi({ uri: 'http://path/to/my/wiki/api.php', domain: 'localhost', prefix: 'localhost' });
Again, the "domain" property is optional in the Parsoid configuration; it defaults to the hostname used in the uri property if not specified.
The "prefix" property can also be omitted unless you are running an older version of Parsoid.
Make sure the domain and prefix listed in Parsoid's localsettings.js match what's in your wiki's LocalSettings.php.
See Parsoid/Setup#Configuration for more details.
"maximum function nesting level of '100' reached, aborting"
If you get this error, you need to set xdebug.max_nesting_level = 200, probably in /etc/php5/apache2/php.ini.[१]
"Exception Caught: CAS is not implemented in Xyz"
StructuredDiscussions invokes $cache->cas() and some cache implementations including CACHE_ACCEL (APCBagOStuff) don't implement CAS.
You probably need to use a different cache, for example install memcached and set $wgMainCacheType = CACHE_MEMCACHED;.
अनुमतियाँ
Users must have the core edit 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 edit-post and delete-topic (see the list in FlowActions.php).
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 flow-edit-post 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.
Migrating existing pages
To migrate a single existing page, use Special:EnableStructuredDiscussions. It will handle archiving of a single page (then enabling StructuredDiscussions) automatically.
The script maintenance/convertNamespaceFromWikitext.php 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 maintenance/convertAllLqtPages.php 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#flow.
You can visit Special:PrefixIndex/Topic: to see if there are existing pages that conflict with this; if so run the maintenance script maintenance/namespaceDupes.php.

System messages
Using the "Source editing" option on StructuredDiscussions boards makes visible the help text "विकिटेक्स्ट मार्कअप का इस्तेमाल करता है और आप किसी भी समय परिणाम की झलक देख सकते हैं।".
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 Help:Formatting 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[https://www.mediawiki.org/wiki/Help:Formatting uses markup].Troubleshooting
Not getting Flow as expected? There are different fixes, depending on the source of the problem:
Badly configured parsoid/VE not working
When you get messages like Conversion from 'html' to 'wikitext' was requested, but core's Parser only supports 'wikitext' to 'html' conversion, you probably have a version of MediaWiki (e.g. REL1_39) where the StrucuredDiscussions extension does not use the zero-config parsoid.
For using visual editor on discussions, you must manually configure parsoid-php.
For REL1_39 of MediaWiki and StructuredDiscussions, be sure to do all of the following:
wfLoadExtension('Flow');
wfLoadExtension ('Parsoid', "$IP/vendor/wikimedia/parsoid/extension.json" );
- Set appropriately. See example.
$wgVirtualRestConfig['modules']['parsoid']
Older versions of MediaWiki may need Parsoid-JS and perhaps a code patch:
- Make sure you have correctly installed parsoid.
- When this bug hasn't been resolved, apply this patch to the StructuredDiscussions codebase.
If the problem persists, this discussion might be of some help.
Wrong Custom-Namespace Declaration Order
The Flow declares must go after the declare for a custom namespace. Correct order is:
define("NS_PORTAL_TALK", 3005);
$wgExtraNamespaces[NS_PORTAL_TALK] = "Portal_Talk";
$wgNamespaceContentModels[NS_PORTAL_TALK] = 'flow-board';
$wgNamespacesWithSubpages[NS_PORTAL_TALK] = true;
Wrong Native Constants
Talk pages in the Main namespace are defined as NS_TALK, not NS_MAIN_TALK
The correct declaration is:
$wgNamespaceContentModels[NS_TALK] = 'flow-board';
Non-Registered Extension Constants
Extension:Page Forms namespace constant is supposed to be PF_NS_FORM_TALK.
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.
Old Remnants
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:
- Browse to the talk page that won't load Flow, e.g.: Portal_Talk:Welcome
- Delete the Talk page using the Delete tab.
- Go to the content page for that talk page, e.g.: Portal:Welcome
- Click Discuss.
- You get Flow.
Parsoid not working in StructuredDiscussions (Flow)
To get Parsoid to work with StructuredDiscussions (Flow):
- In
LocalSettings.php, explicitely load Parsoid like so:wfLoadExtension( 'Parsoid', "vendor/wikimedia/parsoid/extension.json" ); - Apply the following patch.
