    Default Answered: Store reading multiple roots

    I have a JSON like the following:

    {"olditems":"true","items":[]}
    I assigned the reader of my store with the root 'items' because I want this items to populate my template. But I also want to read my olditems value, how can I do this?
    I have tried many things, but, if I set the root as "items" I can no longer have access to "olditems"

    All I need is to access this property in the listener 'load', so I can add an extra record to the store in case this property is set to true.

    Can anyone help me? I'm sure this one is quite easy to solve, but I've been googling around for the last couple of hours and this is driving me crazy!

  2. You can add this to the Store:

    Code:
    getOldItems: function() {
        var reader = this.proxy.reader;
    
        return reader.createAccessor('olditems')(reader.rawData);
    }
    reader.createAccessor creates a function that can look for the key you pass it, in this case you want to look for 'olditems'. You then execute that function passing in the raw data and the reader will then return that value.
