Question

I’ve got the following code, which supposed to create a new item. Proxy type is REST.

var inst = Ext.ModelMgr.create({
                    title: values.title
                }, "EntriesModel");

                inst.save({
                    success: function(model) {
                        console.log(model);
                    }
                });

After save(), I see that request is sent to http://localhost:3000/entries/0.json, while I assume it should have been sent to http://localhost:3000/entries

Entries model looks like this

Ext.regModel("EntriesModel", {
fields: [
    {name: "id",             type: "int"},
    {name: "title",           type: "string"},
    {name: "list_id",       type:"int"},
    {name: "bought",         type: "boolean"},
],

proxy: {
    type: 'rest',
    url: '/entries',
    format: 'json',
    noCache: true,
    reader: {
        type: 'json',
        root: 'data'
    },
    writer: {
        type: 'json'
    },
    listeners: {
        exception: function (proxy, response, operation) {
            console.log(proxy, response, operation);
        }
    }
}
});

Backend is Rails.

Look at this, how building a link for a Rest Proxy:

buildUrl: function(request) {
    var records = request.operation.records || [],
        record  = records[0],
        format  = this.format,
        url     = request.url || this.url;

    if (this.appendId && record) {
        if (!url.match(/\/$/)) {
            url += '/';
        }

        url += record.getId();
    }

    if (format) {
        if (!url.match(/\.$/)) {
            url += '.';
        }

        url += format;
    }

    request.url = url;

    return Ext.data.RestProxy.superclass.buildUrl.apply(this, arguments);
}

Override this to provide further customizations, but remember to call the superclass buildUrl
