I’m getting the next error when I’m trying to save a new record with an associated relationship. The problem I think is related to the creation of the record because ember doesn’t create any record.
`Uncaught TypeError: Cannot call method 'save' of undefined `
On the one hand, my models are the following (with a one-to-many relationship).
```
App.Kid = DS.Model.extend({
attribute1: DS.attr("string"),
parent: DS.belongsTo(parent)
});
App.Parent = DS.Model.extend({
attribute1: DS.attr("string"),
kids: DS.hasMany(kid)
});
```
On the other hand, my route is the following.
```
App.KidRoute = Ember.Route.extend({
model: function (id) {
var store = this.get('store');
store.find('usuario', id).then(function(parentmodel){
return this.store.createRecord('kid', {parent: parentmodel});
});
},
actions:{
save: function(){
this.get('currentModel').save();
}
}
});
```
Any help would be appreciate. Thanks!
**Editing…**
It is necessary to set the mapping on the adapter through `embedded: 'always'`? Any thoughts?

hey there, just a suggestion, people here usually does not reply to this type of questions, it would be better to ask in [Newest 'ember.js' Questions - Stack Overflow](http://stackoverflow.com/questions/tagged/ember.js) . This forum is mostly used for ideas, suggestions, and to discuss new features.

I’d already posted there but I thought this forum would be more helpful for ember questions. Thanks for the clarification!

@alopez, can you please share the Stack Overflow link for this question? I was wondering about this same thing. Did you figure out how to do it? How to save the id for a related record.
