# 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

# Define authentication filters and accessor helpers based on mappings.
# These filters should be used inside the controllers as before_actions,
# so you can control the scope of the user who should be signed in to
# access that specific controller/action.
# Example:
#
# Roles:
# User
# Admin
#
# Generated methods:
# authenticate_user! # Signs user in or 401
# authenticate_admin! # Signs admin in or 401
# user_signed_in? # Checks whether there is a user signed in or not
# admin_signed_in? # Checks whether there is an admin signed in or not
# current_user # Current signed in user
# current_admin # Current signed in admin
# user_session # Session data available only to the user scope
# admin_session # Session data available only to the admin scope
# render_authenticate_error # Render error unless user or admin is signed in
#
# Use:
# before_action :authenticate_user! # Tell devise to use :user map
# before_action :authenticate_admin! # Tell devise to use :admin map
