scope vs not scope example

[kurtbrose]

had a real world example of a using-scope vs data structures outside of scope pop up

thought it might be helpful to rework for cookbook or docs -- showing a relatively simple case how both approaches work

def totally_outside_glom():
    models = queryset()
    models_by_id = { model.id: model for model in models}
    values = models.values('id', 'bar')
    for valdict in values:
        valdict['model'] = models_by_id[val_dict[['id']]]
    glom(values,
        [{
            'foo': ('model.foo', T()),
            'bar': 'bar'
        }])


def using_scope():
    models = queryset()
    values = models.values('id', 'bar')
    glom(values,
        [{
            'foo': S['models-by-id'][T['id']].foo(),
            'bar': 'bar',
        }],
        scope={
            'models-by-id': { model.id: model for model in models}
        }
    )

maybe it could be pushed even further down into the scope

neither approach is really perfect, they both have a little bit of rough edges
