    Default Unanswered: HasMany Association not saved by REST proxy

    Unanswered: HasMany Association not saved by REST proxy


    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:
    Code:
    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:
    Code:
    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.
