Fail test scenario

/*

User database rows:

id(integer)     metadata(json)
1               [{'a':1},{'a':2}]
2               [{'b':5},{'b':8}]

*/

var user = db.define({
    name: 'user',
    columns: {
        'id': {primaryKey: true}, 
        'metadata':{}
    }
});

t.test('get user metadata', function(t) {
        user.from(user)
                .where(user.id.equals(1))
                .selectDeep(user)
                .all(function(err,user){
                        t.notOk(user.metadata instanceof Array == false, "The metadata should be an Array object");
                        t.end();
                });
});

Figured it out - this happens in the cleaner. The reason is - the cleaner doesn't know that metadata is supposed to have an array type (thats unaccounted for in column types).

To fix this we will need to special-case JSON columns.

Edit: no, just special-casing has properties that are not of type many worked pretty well.

fixed in v0.6.12
