1.修改: /app/controllers/application_controller.rb文件为如下样子:
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
#以下为本次添加内容
rescue_from Exception, :with => :handle_exception
def not_found
render :template => "shared/not_found", :status => 404
end
private
def handle_exception(exception)
# case exception
# when CanCan::AccessDenied
# authenticate_user!
# when ActiveRecord::RecordNotFound
# not_found
# else
internal_server_error(exception)
# end
end
def internal_server_error(exception)
render :file => "public/500.html", :status =>500, :layout=>false
end
end
2.修改 config/routes.rb 文件,把其最后一行变成:
match "*any", :to =>"application#not_found", via: :all
end
3.完成.
