Modul:ResolveEntityId

Dokumentacija modula

Usage

Functions similarly to mw.wikibase.resolvePropertyId, but for Wikidata entities instead of properties.

Returns an entity id for the given label or id. This allows using the entity's labels instead of ids in all places. If no entity was found for the label or id, or if the label is ambiguous, a nil value is returned.

When attempting to resolve a label, only entities with English Wikipedia sitelinks are considered in the search. If a label exists in Wikidata, but does not have the requisite language sitelink, a nil value is returned.

Call from within a module (_id)

Example calls within a module might look like the following:

Code	Result
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('Q42')	id = Q42
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('Q0')	id = nil
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('Q404')	id = Q404
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('Q151384451555')	id = nil
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('Douglas Adams')	id = Q42
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('ThisIsNotARealWikidataItem')	id = nil
local resolveEntity = require( "Module:ResolveEntityId" ) id = resolveEntity._id('ThisIsNotARealWikidataItem', 'Wikidata ID not found!')	id = 'Wikidata ID not found!'

Use from within a template (entityid)

The following will return the entity id (or nil if the ID doesn't exist): {{#invoke:ResolveEntityId|entityid|id}}

The following will return the entity id (or the alternate text if the ID doesn't exist): {{#invoke:ResolveEntityId|entityid|id|alternate text if id is nil}}

Deprecated (_entityid)

The _entityid function, which required that the frame be passed as the first argument, has been deprecated because workarounds are no longer needed for phab:T143970.
