assign_current_user(conn, user, config)

View Source
@spec assign_current_user(Plug.Conn.t(), any(), Pow.Config.t()) :: Plug.Conn.t()

Assign an authenticated user to the connection.

This will assign the user to the conn. The key is by default :current_user, but it can be overridden with :current_user_assigns_key configuration option.

Link to this function

authenticate_user(conn, params)

View Source
@spec authenticate_user(Plug.Conn.t(), map()) :: {:ok | :error, Plug.Conn.t()}

Authenticates a user.

If successful, a new session will be created.

Link to this function

change_user(conn, params \\ %{})

View Source
@spec change_user(Plug.Conn.t(), map()) :: map()

Creates a changeset from the current authenticated user.

@spec create(Plug.Conn.t(), map()) :: Plug.Conn.t()

Call create/3 for the Pow plug set for the conn.

Link to this function

create(conn, user, config)

View Source
@spec create(Plug.Conn.t(), map(), Pow.Config.t()) :: Plug.Conn.t()
Link to this function

create_user(conn, params)

View Source
@spec create_user(Plug.Conn.t(), map()) ::
  {:ok, map(), Plug.Conn.t()} | {:error, map(), Plug.Conn.t()}

Creates a new user.

If successful, a new session will be created.

@spec current_user(Plug.Conn.t()) :: map() | nil

Get the current user assigned to the conn.

The config is fetched from the conn. See current_user/2 for more.

Link to this function

current_user(map, config)

View Source
@spec current_user(Plug.Conn.t(), Pow.Config.t()) :: map() | nil

Get the current user assigned to the conn.

This will fetch the user from the assigns map in the conn. The key is by default :current_user, but it can be overridden with :current_user_assigns_key configuration option.

@spec delete(Plug.Conn.t()) :: Plug.Conn.t()

Call delete/2 for the Pow plug set for the conn.

@spec delete(Plug.Conn.t(), Pow.Config.t()) :: Plug.Conn.t()
@spec delete_user(Plug.Conn.t()) ::
  {:ok, map(), Plug.Conn.t()} | {:error, map(), Plug.Conn.t()}

Deletes the current authenticated user.

If successful, the user authentication will be cleared from the session.

@spec fetch_config(Plug.Conn.t()) :: Pow.Config.t()

Fetch configuration from the private key in the connection.

It'll raise an error if configuration hasn't been set as a private key.

@spec get_plug(Pow.Config.t()) :: atom()
Link to this function

prepend_with_namespace(config, string)

View Source
@spec prepend_with_namespace(Pow.Config.t(), binary()) :: binary()

Prepend namespace found in Plug Pow configuration to binary.

Will prepend :otp_app if exists in configuration.

Link to this function

put_config(conn, config)

View Source
@spec put_config(Plug.Conn.t(), Pow.Config.t()) :: Plug.Conn.t()

Put the provided config as a private key in the connection.

Link to this function

sign_token(conn, salt, token, config \\ nil)

View Source
@spec sign_token(Plug.Conn.t(), binary(), binary(), Pow.Config.t() | nil) :: binary()

Signs a token for public consumption.

Used to prevent timing attacks with token lookup.

This uses Pow.Plug.MessageVerifier by default, but can be changed if the Pow configuration is set with :message_verifier. Pow.Plug.MessageVerifier can also be configured in this way if :message_verifier is set to {Pow.Plug.MessageVerifier, key_generator_opts: [length: 64]}

Link to this function

update_user(conn, params)

View Source
@spec update_user(Plug.Conn.t(), map()) ::
  {:ok, map(), Plug.Conn.t()} | {:error, map(), Plug.Conn.t()}

Updates the current authenticated user.

If successful, a new session will be created.

Link to this function

verify_token(conn, salt, token, config \\ nil)

View Source
@spec verify_token(Plug.Conn.t(), binary(), binary(), Pow.Config.t() | nil) ::
  {:ok, binary()} | :error

Decodes and verifies a token.

Used to prevent timing attacks with token lookup.

This uses Pow.Plug.MessageVerifier by default, but can be changed if the Pow configuration is set with :message_verifier. Pow.Plug.MessageVerifier can also be configured in this way if :message_verifier is set to {Pow.Plug.MessageVerifier, key_generator_opts: [length: 64]}
