[英]hasMany association in Ember js
app/models/card.js应用程序/模型/card.js
export default Model.extend({
title: attr('string'),
description: attr('string'),
users: hasMany('user')
});
app/models/user.js应用程序/模型/user.js
export default Model.extend({
email: attr('string'),
name: attr('string')
});
app/routes/card/new.js应用程序/路由/卡/new.js
actions: {
save(title, description) {
const newCard = this.get('store').createRecord('card', {
title,
description
});
this.get('store').findRecord('user', 1).then(function(user) {
newCard.set('users', user);
console.log(newCard);
});
newCard.save().then((card) => {
// go to the new item's route after creating it.
this.transitionTo('card.card', card);
});
}
}
So, when I'm saving a card
, it is throwing me this error:因此,当我保存
card
,它向我抛出了这个错误:
Assertion Failed: You must pass an array of records to set a hasMany relationship
. Assertion Failed: You must pass an array of records to set a hasMany relationship
。
I want to create an association between the newly created card
and the user
.我想在新创建的
card
和user
之间创建关联。

You defined that a card has many users:你定义了一张卡片有很多用户:
users: hasMany('user')
So you can's set 'users' to a single user:因此,您可以将“用户”设置为单个用户:
newCard.set('users', user);
So you could either change the hasMany
to a belongsTo
, or set the 'users' instead to just one user
to an array of users: [user]
因此,您可以将
hasMany
更改为belongsTo
,或者将“用户”设置为仅一个user
到一组用户: [user]
