如何从其他商店功能更新商店
How to update a store from other store function
我有 2 个商店,即 AttachmentStore 和 CommentStore。
export class AttachmentStore {
@observable attachments = []
}
export class CommentStore {
@observable comments = []
save_comment_and_attachment(comment, attachments) {
this.comments.push(comment);
//how can I push the attachment to the
//attachments observable
}
}
我知道我可以将附件声明为 CommentStore observable 的一部分,但是有什么方法可以更新从 CommentStore observable 的附件吗?
export class AttachmentStore {
@observable attachments = [];
@action add(attachments) {
// ...
}
}
export class CommentStore {
@observable comments = [];
attachmentStore = null;
init(stores) {
this.attachmentStore = stores.attachmentStore;
}
@action save_comment_and_attachment(comment, attachments) {
this.comments.push(comment);
this.attachmentStore.add(attachments);
}
}
const stores = {
attachmentStore: new AttachmentStore(),
commentStore: new CommentStore(),
};
Object.values(stores)
.filter(store => store.init)
.forEach(store => store.init(stores));
