How to use

1.Define your structs

    type Dog struct {
        ID int64
        Name string
        Age int64
        Modified time.Time
    }

2.Implement Entity interface. It's up to you how and what values to use for your datastore.Key

func (d Dog) Key(ctx context.Context) *datastore.Key {
	if d.ID == 0 {
		return datastore.NewIncompleteKey(ctx, "Dog", nil)
	}
	return datastore.NewKey(ctx, "Dog", "", d.ID, nil)
}

3.Implement Preparer interface (optional). This is executed after your entity is retrieved. Put any post processing logic like setting your struct to store the int or string id from the key

func (d *Dog) Prepare(key *datastore.Key) {
	d.ID = key.IntID()
}

4.Implement BeforePutter interface (optional). This is executed before your entity is saved

func (d *Dog) BeforePut() error {
    d.Modified = time.Now()
    return nil
}

5.Start using it!

// Put
dog := Dog{Name: "Winston", Age: 2}
key, err := gae.Put(ctx, &dog)

// Get
dog := Dog{ID: 1234}
err := gae.Get(ctx, &dog)
