| 40x40px | This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected. |
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 entitiy was found for the label or id, or if the label is ambiguous, a nil value is returned.
Call from within a module
An example call within a module might look like the following:
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'Q42')
which would result in id = Lua error in Module:ResolveEntityId at line 13: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'Q0')
which would result in id = Lua error in Module:ResolveEntityId at line 13: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'Q404')
which would result in id = Lua error in Module:ResolveEntityId at line 13: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'Q151384451555')
which would result in id = Lua error in Module:ResolveEntityId at line 13: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'Douglas Adams')
which would result in id = Lua error in Module:ResolveEntityId at line 22: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'ThisIsNotARealWikidataItem')
which would result in id = Lua error in Module:ResolveEntityId at line 22: attempt to index field 'wikibase' (a nil value).
local resolve = require( "Module:ResolveEntityId" )
id = resolve._entityid(frame, 'ThisIsNotARealWikidataItem', 'Wikidata ID not found!')
which would result in id = Lua error in Module:ResolveEntityId at line 22: attempt to index field 'wikibase' (a nil value).
Use from within a template
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}}
