Ruby on Rails: undefined method `current_user?`

Question

I'm having issues trying to figure out why i'm getting undefined method current_user?'`

In my Application controller:

class ApplicationController < ActionController::Base
  protect_from_forgery
  include SessionsHelper

  # Force signout to prevent CSRF attacks
  def handle_unverified_request
    sign_out
    super
  end

   private
    def current_user
        @current_user ||= User.find(session[:user_id]) if session[:user_id]
    end
     helper_method :current_user

  def authorize
    redirect_to login_url, alert: "Not Autherized" if current_user.nil?
  end

  def track_activity(trackable, action = params[:action])
    current_user.activities.create! action: action, trackable: trackable
  end
end

In my session helper:

module SessionsHelper
  def sign_in(user)
    cookies.permanent[:remember_token] = user.remember_token
    self.current_user = user
  end
  def signed_in?
    !current_user.nil?
  end
  def current_user=(user)
    @current_user = user
  end
  def current_user
    @current_user ||= User.find_by_remember_token(cookies[:remember_token])
  end

  def sign_out
    self.current_user = nil
    cookies.delete(:remember_token)
  end
end

I'm still new to rails I'm following some tutorials, but I'm trying to figure out why I'm getting undefined method for current_user?

This is where my error is occurring- users view folder:

<% unless current_user?(@user) %>
  <div id="follow_form">
  <% if current_user.following?(@user) %>
    <%= render 'unfollow' %>
  <% else %>
    <%= render 'follow' %>
  <% end %>
  </div>
<% end %>

Answer 1

You have not defined a current_user? method anywhere, and you are calling current_user?(@user) .

Perhaps, you need to call signed_in? instead of current_user? , or define what you mean by current_user?(@user)

Answer 2

You have not defined current_user? method. there is a difference between current_user and current_user? current_user? always return a boolean response.

but you can try with current_user(@user)? or unless current_user(@user).nil?

Answer 3

Try this:

  def current_user?(user)
     user == current_user
  end
