Hello. I can not figure out how to push json into a specific object. I make a blog with categories, where in categories there is a field hasMany ().

enter image description here

I can not exactly get into the collection. Here is my sample add code.

var catId = this.get('category'); var postId = newPost.id; newPost.save(); var addtocat = this.store.push('category', catId.posts, { postId : true }); addtocat.save();

I add the post myself, then I take the id from the post and insert it into the category.

    Good day. The push method of the store class is not necessary. It is very rarely used. It is used when, for example, an adapter / serializer is written. And in general, if I'm not mistaken, the push method takes an argument in the form of an object in json-api format. You should have something like this:

     // app/models/post.js export default DS.Model.extend({ autor: DS.attr("string"), body: DS.attr("string"), publish: DS.attr("date"), title: DS.attr("string"), category: DS.belongsTo("category") }); // app/models/category.js export default DS.Model.extend({ name: DS.attr("string"), path: DS.attr("string"), posts: DS.hasMany("post") })

    And in any place (route) you write those. start working

     // создаете post например так let post = this.store.createRecord('post', { autor: "Vasya", body: "Body", publish: new Date(), title: "Title", }); // допустим сохраним на сервере post.save(); // затем создадим category let category = this.store.createRecord('category', { name: "Технологии", path: "Tech" }); category.get("posts").pushObject(post); category.save();

    Something like this. Somewhere could of course be wrong.
