Instance Method Details

#devise_token_auth_group(group_name, opts = {}) ⇒ Object

Define authentication filters and accessor helpers for a group of mappings. These methods are useful when you are working with multiple mappings that share some functionality. They are pretty much the same as the ones defined for normal mappings.

Example:

inside BlogsController (or any other controller, it doesn't matter which):
  devise_group :blogger, contains: [:user, :admin]

Generated methods:
  authenticate_blogger!             # Redirects unless user or admin are signed in
  blogger_signed_in?                # Checks whether there is either a user or an admin signed in
  current_blogger                   # Currently signed in user or admin
  current_bloggers                  # Currently signed in user and admin
  render_authenticate_error         # Render error unless user or admin are signed in

Use:
  before_action :authenticate_blogger!              # Redirects unless either a user or an admin are authenticated
  before_action ->{ authenticate_blogger! :admin }  # Redirects to the admin login page
  current_blogger :user                             # Preferably returns a User if one is signed in
