    Question Answered: How to tell Ext.data.reader.Reader to use state code 200 as successProperty?

    Answered: How to tell Ext.data.reader.Reader to use state code 200 as successProperty?


    Hi, I want to fetch data with JsonP from an foreign Server-API. It returns for success:
    Code:
    {"state":200,"results":[...]}
    and in case of an failure, something like this:
    Code:
    {"state":402,"message":"Please provide a valid ..."}
    Now Ext.data.reader.Reader expects an boolean for successProperty. How will I tell the reader, that all worked fine, if state = 200?

    I think of something like this:
    Code:
    Ext.define('App.model.CoolModel', {    extend: 'Ext.data.Model',
        fields: [
            {name: 'id', type: 'string'},
        ],
        proxy: {
            type: 'jsonp',
            url: 'http://xyz/search/coolapi.json',
            reader: {
                type: 'json',
    
                success: function(data) {
                    return data.state == 200;
                },
    
                root: 'results'
            }
        }
    });
    could someone please point me the right direction? thx Sunny

  2. You will have to override the proxy in the processResponse method. There is a check where result.success !== false, that's where it checks to see if the success property is true/false. So after the result variable get's filled with data from the reader, you will need to set result.success.

    The successProperty is expecting a boolean value... 200 is truthy in javascript but so is 500 or 402

    Yes, makes sense. But how do I tell the reader that response state = 200 is success?
