 | This is the documentation page for a particular constraint type. See Help:Property constraints portal for a general overview of property constraints. |
allowed-entity-types constraint (Q52004125) 声明一个属性只能用于特定实体类型。
For example, Wikidata property example (P1855) should only be used on properties—not on items—so P1855 has the following statement:
| property constraint (P2302) |
| ||||||||||||
| add value | |||||||||||||
The qualifier constraint scope (P4680) can be used to restrict the constraint to only apply when a property is used as a main value, as a qualifier, or as a references.
如果未指定constraint scope (P4680)，則會在任何位置檢查此約束。
可能的动作
有幾種方法可以解決違反此約束的問題：
- It’s possible that the property is not the correct one to use for the statement, and a similar but different property should be used instead.
- It’s possible that the statement should not exist at all, and should be removed.
- 有可能此声明是一个罕见，但正确的約束例外，无需采取任何行动。
