    Default Answered: Cannot get simple belongsTo sample code to work?

    Answered: Cannot get simple belongsTo sample code to work?


    I've tried two different examples of a simple belongsTo "getter" and both of them yield the error message "Uncaught Error: [ERROR][Anonymous] You are trying to load a model that doesn't have a Proxy specified"

    One is in the API documentation for "belongsTo".

    The other is a response in a forum thread.

    I posted a question about using this in a list with the "prepareData" config property, but got no response. Now trying to use it in a non-list context. Does it actually work. Can someone point me to a working examples?

    Any other suggestions? Thanks.

  2. Working for me:

    Code:
    Ext.define('Post', {
        extend : 'Ext.data.Model',
    
        config : {
            fields : ['id', 'user_id'],
            proxy  : {
                type   : 'ajax',
                url    : 'data/json.json',
                reader : 'json'
            }
        }
    });
    
    Ext.define('Comment', {
        extend : 'Ext.data.Model',
    
        config : {
            fields    : ['id', 'user_id', 'post_id'],
            belongsTo : 'Post'
        }
    });
    
    Ext.application({
        name   : 'Test',
    
        launch : function () {
    
            var comment = new Comment({
                id      : 1,
                user_id : 1,
                post_id : 1
            });
    
            comment.getPost({
                callback : function (post) {
                    console.log(post);
                }
            });
    
        }
    });
    data/json.json:

    Code:
    {
        "id"      : 1,
        "user_id" : 1
    }

    Thanks for taking the time to try it out. Must be something I'm not doing right. I'll go back and try a few more things.
