在打字稿，你怎麼了，你鍵入特定的鍵對象常量

Question

所以我有這個數據結構

export interface StoreData { 
    msdb: {[tableName: string]: List<StoreModel>}; 
} 

，但我想只允許（並獲得IntelliSence）對我的表名特定字符串的值。 所以，我試圖像下面，但它沒有工作：

var tableNames:'table_campaigns' | 'table_resources' 
export interface StoreData { 
    msdb: {[tableName]: List<StoreModel>}; 
} 

也試過，沒有運氣

interface IMyTables { 
    'table_campaigns: string 
    'table_resources: string; 
} 

type MyTables = keyof IMyTables; 

export interface StoreData { 
    participants: { [key: number]: any }; 
    threads: { [key: number]: any }; 
    messages: { [key: number]: any }; 
    msdb: {MyTables: List<StoreModel>}; 
} 

也試過

type allMyTables = 'table_campaigns' | 'table_resources' 

export interface StoreData { 
    msdb: {[tableName: allMyTables]: List<StoreModel>}; 
} 




Thanks for reading,

感謝傑夫，即做到了：

export interface StoreData { 
    participants: { [key: number]: any }; 
    threads: { [key: number]: any }; 
    messages: { [key: number]: any }; 
    msdb: { 
     'table_campaigns': List<StoreModel>; 
     'table_resources': List<StoreModel>; 
    }; 
}
