我有两个Ember型号:a items和comments.用户将发布项目,其他用户将能够对项目发表评论.

我无法在firebase中设置允许name和description仅由当前用户写入的安全规则,但允许comments由任何登录用户写入.

项目

// app/models/item.js
export default DS.Model.extend({
  name: DS.attr('string'),
  description: DS.attr('string'),
  comments: DS.hasMany('comment'),
  user: DS.belongsTo('user')
})

评论

// app/models/comment.js
export default DS.Model.extend({
  user: DS.belongsTo('user')
  body: DS.attr('string'),
  timestamp: DS.attr('string'),
  item: DS.belongsTo('user')
})

保存评论

// app/components/comment-form.js
const comment = this.get('comment');
const item = this.get('item');
// service that tracks the currently logged in user
const currentUser = this.get('sessionManager.user');
comment.set('timestamp', new Date());
comment.set('user', currentUser);

// setup both sides of the relationship
item.get('comments').pushObject(comment);
comment.set('item', …
