Topic on Extension talk:StructuredDiscussions

I have tried to configure flow for the additional namespaces like this:

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

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

But it does not work in any of those 2 configurations, either:

$ wgNamespaceContentModels [TALK_ Movie] = 'flow-board';

how can I make it to put flow in additional (custom) namespaces

Have you run the scripts mentioned in Extension:StructuredDiscussions#Enabling or disabling StructuredDiscussions?

yes

And do you experience any other unexpected behavior apart from seeing wikitext talk pages?

no, nothing

In the places where you have "Movie_discussion", "NS_Pilm_discussion", etc., try replacing those with the namespace numbers for those namespaces. You've probably created these namespaces with $wgExtraNamespaces[1235] = 'Movie_discussion'; where 1235 is some number; use that number to then set $wgNamespaceContentModels[1235] = 'flow-board';

I ALREADY WORK THIS WAS WHAT I DID

define("NS_Música", 50000); // This MUST be even.

define("NS_Música_DISCUSIÓN", 50001); // This MUST be the following odd integer.

$wgExtraNamespaces[NS_Música] = "Música";

$wgExtraNamespaces[NS_Música_DISCUSIÓN] = "Música_discusión";

$wgNamespaceProtection[NS_Música] = array( 'editMúsica' ); // permission "editfoo" required to edit the foo namespace

$wgNamespacesWithSubpages[NS_Música] = true;            // subpages enabled for the foo namespace

$wgGroupPermissions['*']['editMúsica'] = true;      // permission "editfoo" granted to users in the "sysop" group

AND TO PUT FLOW IN THAT SPACE OF NAMES PUSE:

$wgNamespaceContentModels[50001] = 'flow-board';

and then the result was that in the discussion pages of the music namespace, flow was active.
