Struct rocket_auth::Users [−][src]
pub struct Users { /* fields omitted */ }
Expand description
The Users
struct is used to query users from the database, as well as to create, modify and delete them.
Implementations
It creates a Users
instance by connecting it to a sqlite database.
This method uses the sqlx
crate.
If the database does not yet exist it will return an Error. By default,
sessions will be stored on a concurrent HashMap. In order to have persistent sessions see
the method open_redis
.
let users = Users::open_sqlite("database.db").await?;
rocket::build()
.manage(users)
.launch()
.await;
Initializes the user table in the database. It won’t drop the table if it already exists.
It is necessary to call it explicitly when casting the Users
struct from an already
established database connection and if the table hasn’t been created yet. If the table
already exists then this step is not necessary.
let mut conn = SqlitePool::connect("database.db").await?;
let mut users: Users = conn.into();
users.open_redis("redis://127.0.0.1/")?;
users.create_table().await?;
Opens a redis connection. It allows for sessions to be stored persistently across
different launches. Note that persistent sessions also require a secret_key
to be set in the Rocket.toml configuration file.
let mut users = Users::open_sqlite("database.db").await?;
users.open_redis("redis://127.0.0.1/")?;
rocket::build()
.manage(users)
.launch();
It creates a Users
instance by connecting it to a sqlite database.
This method uses the rusqlite
crate.
If the database does not yet exist it will attempt to create it. By default,
sessions will be stored on a concurrent HashMap. In order to have persistent sessions see
the method open_redis
.
let users = Users::open_rusqlite("database.db")?;
rocket::build()
.manage(users)
.launch()
.await;
It creates a Users
instance by connecting it to a postgres database.
This method uses the sqlx
crate.
let users = Users::open_postgres("postgres://postgres:password@localhost/test").await?;
rocket::build()
.manage(users)
.launch();
It creates a Users
instance by connecting it to a mysql database.
This method uses the sqlx
crate.
let users = Users::open_mysql(DATABASE_URL).await?;
rocket::build()
.manage(users)
.launch();
It queries a user by their email.
#[get("/user-information/<email>")]
async fn user_information(email: String, users: &State<Users>) -> Result<String, Error> {
let user = users.get_by_email(&email).await?;
Ok(format!("{:?}", user))
}
It queries a user by their email.
let user = users.get_by_id(3).await?;
format!("{:?}", user);
Inserts a new user in the database. It will fail if the user already exists.
#[get("/create_admin/<email>/<password>")]
async fn create_admin(email: String, password: String, users: &State<Users>) -> Result<String, Error> {
users.create_user(&email, &password, true).await?;
Ok("User created successfully".into())
}
Deletes a user from de database. Note that this method won’t delete the session.
To do that use Auth::delete
.
#[get("/delete_user/<id>")]
async fn delete_user(id: i32, users: &State<Users>) -> Result<String> {
users.delete(id).await?;
Ok("The user has been deleted.")
}
Trait Implementations
Additionally, Users
can be created from a tuple,
where the first element is a database connection, and the second is a redis connection.
let (db_client, connection) = tokio_postgres::connect(postgres_path, NoTls).await?;
let redis_client = redis::Client::open(redis_path)?;
let users: Users = (db_client, redis_client).into();
// we create the user table in the
// database if it does not exists.
users.create_table();
A Users
instance can also be created from a database connection.
let (client, connection) = tokio_postgres::connect("host=localhost user=postgres", NoTls).await?;
let users: Users = client.into();
// we create the user table in the
// database if it does not exists.
users.create_table();
