This plug ensures that a resource is not loaded.

If one is found, the auth_error will be called with :already_authenticated

This might be used directly, however the typical curator load_resource plug should be used. If there is a case where it’s imperative the user isn’t signed in this will accomplish that.

This, like all other Guardian plugs, requires a Guardian pipeline to be setup. It requires an implementation module, an error handler and a key.

These can be set either:

1. Upstream on the connection with plug Guardian.Pipeline
2. Upstream on the connection with Guardian.Pipeline.{put_module, put_error_handler, put_key}
3. Inline with an option of :module, :error_handler, :key

Options:

• key - The location to find the information in the connection. Defaults to: default

Example

  # setup the upstream pipeline
  plug Curator.Plug.EnsureNoResource
  plug Curator.Plug.EnsureNoResource, key: :secret
