heres the code...

pub fn create(user: &NewUser, connection: &DieselConnection, logger: &Logger) -> Result<User, diesel::result::Error> {
	let statement = diesel::insert(user)
	.into(users::table);

	info!(logger, "Executing Query"; "query" => debug_sql!(statement), "user" => format!("{:?}", user));

	let new_user = statement.execute(&**connection);
	//<User>

	match new_user {
		Ok(new_user) => Ok(new_user),
		Err(error) => {
			warn!(logger, "Error creating user"; o!("error" => format!("{:?}", error)));
			Err(error)
		},
	}
}

help me please im newbie.

execute returns the number of affected rows.
For mysql there is no way that an insertstatment returns the inserted row, this needs a distinct query.

[haruhinoshana]

is there a work around to get the last_insert_id or let new_user = statement.get_result::(&**connection); in mysql diesel sir..
