Rails: Before Process_Action Callback: Authenticate_User! Has Not Been Defined

Rails: Before process_action callback :authenticate_user! has not been defined

Twilio developer evangelist here.

It looks like this was a problem that Rails 5 seems to have introduced. If the filter hasn't been defined by the time it is used in a controller it will raise an error. This was discovered in the Clearance project too.

Their fix was to pass the raise: false option to skip_before_filter:

class MessagesController < ApplicationController
  skip_before_filter :verify_authenticity_token 
  skip_before_filter :authenticate_user!, :only => "reply", :raise => false

end

Before process_action callback :require_no_authentication has not been defined

Here is the solution. I was not skipping the require_login method which I have made to check whether user has authentication_token or not

class ConfirmationsController < Devise::ConfirmationsController
  skip_before_action :require_login!

  def new
    super
  end

  def create
    super
  end

  def show
    self.resource = resource_class.confirm_by_token(params[:confirmation_token])

    if resource.errors.empty?
      set_flash_message(:notice, :confirmed) if is_navigational_format?
      sign_in(resource_name, resource)
      respond_with_navigational(resource) { redirect_to after_confirmation_path_for(resource_name, resource) }
    else
      respond_with_navigational(resource.errors, status: :unprocessable_entity) { render :new }
    end
  end

  private

  def after_confirmation_path_for(resource_name, resource)
    if signed_in?(resource_name)
      signed_in_root_path(resource)
    else
      new_session_path(resource_name)
    end
  end
end

After updating to Rails 5 and Devise 4.0.0.rc1, the devise authenticate_user! method is not defined

I could identify the issue, in rails 5, there will be an exception if the skipping method is not defined at the time of calling unless we add :unless condition.

skip_before_action and Rails 5

According to this thread

ActiveSupport::Callbacks#skip_callback now raises an ArgumentError if an unrecognized callback is removed.

So your solution is to pass raise: false option to skip_before_action:

skip_before_action :redirect_heroku_user, raise: false

See the changelog for more info.

How can I fix the Twilio::REST::RestError?

Hard to say with the level of detail given but usually there is an error in your secrets.yml file. Double check that our Twilio Keys are set properly.

Devise before_action : authentication exception

The before_action option except expects an action name, not a controller name. As is, your code is skipping authentication for any action named urls.

To skip authentication for urls#shortcustom and urls#shortened, you need to include

skip_before_action :authenticate_user!, :only => [:shortcustom, :shortened]

in your UrlsController.
