Instance Method Details

#sign_in(resource_or_scope, *args) ⇒ Object

Sign in a user that already was authenticated. This helper is useful for logging users in after sign up.

All options given to sign_in is passed forward to the set_user method in warden. The only exception is the :bypass option, which bypass warden callbacks and stores the user straight in session. This option is useful in cases the user is already signed in, but we want to refresh the credentials in session.

Examples:

 :user, @user                      # sign_in(scope, resource)
 @user                             # sign_in(resource)
 @user, event: :authentication  # sign_in(resource, options)
 @user, store: false            # sign_in(resource, options)
 @user, bypass: true            # sign_in(resource, options)

def (resource_or_scope, *args)
  options  = args.extract_options!
  scope    = Devise::Mapping.find_scope!(resource_or_scope)
  resource = args.last || resource_or_scope

  expire_data_after_sign_in!

  if options[:bypass]
    warden.session_serializer.store(resource, scope)
  elsif warden.user(scope) == resource && !options.delete(:force)
    # Do nothing. User already signed in and we are not forcing it.
    true
  else
    warden.set_user(resource, options.merge!(scope: scope))
  end
end

#sign_out(resource_or_scope = nil) ⇒ Object

Sign out a given user or scope. This helper is useful for signing out a user after deleting accounts. Returns true if there was a logout and false if there is no user logged in on the referred scope

Examples:

sign_out :user     # sign_out(scope)
sign_out @user     # sign_out(resource)

end

#sign_out_all_scopes(lock = true) ⇒ Object

Sign out all active users or scopes. This helper is useful for signing out all roles in one click. This signs out ALL scopes in warden. Returns true if there was at least one logout and false if there was no user logged in on all scopes.
