销毁 Ember 数据记录时出错

Question

我在删除 Ember 数据记录时遇到错误，我无法弄清楚原因，

Attempted to handle event `pushedData` on <card:32> while in state root.deleted.inFlight. 
Error

下面的代码是触发错误的地方，

    deleteBtnClicked() {
        const controller = this.controllerFor('browse/index');
        let selectedCards = controller.getSelectedCard();
        selectedCards = selectedCards.map((card) => {
            return parseInt(Ember.get(card, 'id'));
        });

        selectedCards.forEach((id) => {
            this.store.find('card', id)
                .then((card) => {
                    card.destroyRecord();
                });
        });
    }

原来记录删除成功，但错误依旧

Answer 1

find is private method so please don't use it. Instead you can use findAll and findRecord

deleteBtnClicked() {
    const controller = this.controllerFor('browse/index');
    let selectedCards = controller.getSelectedCard();
    //if selectedCards itself is RecordArray you can easily iterate using forEach and destroyRecord. no need of findRecord.
    selectedCards = selectedCards.map((card) => {
        return parseInt(Ember.get(card, 'id'));
    });
    //I added reload: true this will ensure promise will be resolved only after adapters returns the data.
    selectedCards.forEach((id) => {
        this.store.findRecord('card', id, { reload: true })
            .then((card) => {
                card.destroyRecord();
            });
    });
}
