# frozen_string_literal: true

# Adds support for default and action_missing rendering of Phlex views. So instead of this:
#
#   class UsersController
#     def index
#       render Views::Users::Index.new
#     end

#     def show
#       render Views::Users::Show.new(user)
#     end
#   end
#
# You can do this:
#
#   class UsersController
#     include Phlexible::Rails::ActionController::ImplicitRender
#   end
#
module Phlexible

    module ActionController
      module ImplicitRender
        def default_render
          render_plex_view({ action: action_name }) || super
        end

        def assign_phlex_accessors(pview)
          pview.tap do |view|
            if view.respond_to?(:__controller_attributes__)
              view.__controller_attributes__.each do |attr|
                view.instance_variable_set :"@#{attr}", view_assigns[attr.to_s]
              end
