action(controller, conn, params)

Specs

action(atom(), Plug.Conn.t(), map()) :: Plug.Conn.t()

Handles the controller action call.

If a :controller_callbacks module has been set in the configuration, then before_process and before_respond will be called on this module on all actions.

messages(conn, fallback)

Specs

messages(Plug.Conn.t(), atom()) :: atom()

Fetches messages backend from configuration, or use fallback.

put_no_cache_header(conn, opts)

Specs

put_no_cache_header(Plug.Conn.t(), Keyword.t()) :: Plug.Conn.t()

Ensures that the page can't be cached in browser.

This will add a "cache-control" header with "no-cache, no-store, must-revalidate" if the cache control header hasn't been changed from the default value in the Plug.Conn struct.

require_authenticated(conn, opts)

Specs

require_authenticated(Plug.Conn.t(), Keyword.t()) :: Plug.Conn.t()

Ensures that user has been authenticated.

Pow.Phoenix.PlugErrorHandler is used as error handler. See Pow.Plug.RequireAuthenticated for more.

require_not_authenticated(conn, opts)

Specs

require_not_authenticated(Plug.Conn.t(), Keyword.t()) :: Plug.Conn.t()

Ensures that user hasn't been authenticated.

Pow.Phoenix.PlugErrorHandler is used as error handler. See Pow.Plug.RequireNotAuthenticated for more.

route_helper(atom()) :: binary()

routes(conn, fallback)

Specs

routes(Plug.Conn.t(), atom()) :: atom()

Fetches routes backend from configuration, or use fallback.
