### Delete

[Upsert](https://www.postgresql.org/docs/9.5/static/sql-insert.html) allows you to perform an insert

### Reload
|

reloadall slice
|
||||
In the event that your objects get out of sync with the database for whatever reason,
|
||||
you can use `Reload` and `ReloadAll` to reload the objects using the primary key values
|
||||
attached to the objects.
|
||||
|
||||
```go
|
||||
pilot, _ := models.FindPilot(db, 1)
|
||||
|
||||
// > Object becomes out of sync for some reason
|
||||
|
||||
// Refresh the object with the latest data from the db
|
||||
err := pilot.Reload(db)
|
||||
|
||||
// Reload all objects in a slice
|
||||
pilots, _ := models.Pilots(db).All()
|
||||
err := pilots.ReloadAll(db)
