We can also use this same approach to access the request body in an exception handler.

All we need to do is handle the request inside a `try`/`except` block:

{* ../../docs_src/custom_request_and_route/tutorial002.py hl[13,15] *}

If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

				// Make sure to rollback when panic, Block error or Commit error
				if panicked || err != nil {
					db.RollbackTo(fmt.Sprintf("sp%d", spID))
				}
			}()
		}
		err = fc(db.Session(&Session{NewDB: db.clone == 1}))
	} else {
		tx := db.Begin(opts...)
		if tx.Error != nil {
			return tx.Error
		}

		defer func() {
			// Make sure to rollback when panic, Block error or Commit error

1. This is the generator function. It's a "generator function" because it contains `yield` statements inside.
2. By using a `with` block, we make sure that the file-like object is closed after the generator function is done. So, after it finishes sending the response.
