HasMany Association not saved by REST proxy

[[email protected]]

Hi,

I am trying to use the HasMany Association between to models. I can load it fine but I can't save new associations using a REST proxy.

I have the models Substance and SubstanceGroup. A substance group contains many substances and a substance may be used in several groups.

I've got one REST resources substance for the substances and another REST resource substance_group for the substance groups.

My current model classes look like:

Ext.define('substance_groups.model.Substance', {
    extend: 'Ext.data.Model',


    idProperty: 'id',


    fields: [
        {
            name: 'id',
            type: 'string'
        },
        {
            name: 'name'
        }
    ],
    proxy: {
        type: 'rest',
        url: '../../../../../api/substance'
    }
});

Ext.define('substance_groups.model.SubstanceGroup', {
    extend: 'Ext.data.Model',


    requires: [
        'substance_groups.model.Substance'
    ],
    uses: [
        'substance_groups.model.Substance'
    ],


    idProperty: 'id',


    fields: [
        {
            name: 'id'
        },
        {
            name: 'name',
            type: 'string'
        }
    ],
    hasMany: {
        model: 'substance_groups.model.Substance',
        autoLoad: true,
        name: 'substances'
    },
    proxy: {
        type: 'rest',
        url: '../../../../../api/substance_group'
    }
});

When I add substances to a group using the store group.substances() it is displayed fine. Yet when I save it no substances are transferred.

What I would like to see is something like:

POST api/substance_group
{
  id: '242',
  name: 'My Group',
  substances: [
    {
       substance_id: '123'
    },
    {
       substance_id: '456'
    }
  ]
}

Any hints on how to do that? Help very much appreciated!!

I don't believe store syncing work with associations, least last I tried while back.

Ok thanks. I thought so too and started building the JSON manually which is fine.
