[英]How to use nested call to DataStore in emberJS?
我試圖再次從THEN()函數中調用數據存儲區,以基於FIRST數據存儲區的建立從第二個DS檢索數據,但是THEN()函數中不提供“ this”。 如何執行類似於以下示例的操作。 第二次調用this.store.findRecord不起作用?
actions:{
onBookStoreSelect(bookstore){
console.log(bookstore.id);
this.store.findRecord('boston_city_bookstores', bookstore.id).then(function(response){
console.log(response);
console.log(response.get('bookstore_address'));
console.log(response.get('bookstore_owner'));
console.log(response.get('bookstore_key_ID'));
this.store.findRecord('books', response.get('bookstore_key_ID')).then(function(bookList){
//do something
});
您可以使用箭頭功能維護this
參考。
onBookStoreSelect(bookstore) {
return this.store.findRecord('boston_city_bookstores', bookstore.id).then((response) => {
return this.store.findRecord('books', response.get('bookstore_key_ID')).then((bookList) => {
//do something and return the result if you are using it in caller place.
});
});
}
