Full Stack JavaScript Techdegree Graduate 30,885 PointsWhenever I render the application in the web browser I get an error message even after downloading the project files
Hi,
So after downloading the project files and then attempting to render the application in the browser at around 5:00 minutes in the video, I get an error in the browser saying:
"ActiveRecord::RecordNotFound in TodoListsController#index"
"Couldn't find User with id=3".
Followed by:
Extracted source (around line #14):
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user
app/controllers/application_controller.rb:14:in `current_user'
app/controllers/application_controller.rb:19:in `require_user'
Here's what the application_controll.rb file looks like:
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
add_flash_types :success
private
def logged_in?
current_user
end
helper_method :logged_in?
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user
def require_user
if current_user
true
else
redirect_to new_user_session_path, notice: "You must be logged in to access that page."
end
end
end
Thanks!

Full Stack JavaScript Techdegree Graduate 30,885 PointsLaura Cressman I think you may be right. I did pretty much copy it. I downloaded the exact files and I never touched the application_controller.rb file. What could I do from the console to populate the database?
Maciej Czuchnowski

Full Stack JavaScript Techdegree Graduate 30,885 PointsHi Maciej Czuchnowski I deleted the entire app and downloaded the files again, did exactly the steps you outlined above, yet I still get the typical rails error displayed in the web browser:
"ActiveRecord::RecordNotFound in TodoListsController#index Couldn't find User with id=3".
Maciej Czuchnowski
36,441 PointsOK, I'll check it out and let you know what I find :)
alborz
Full Stack JavaScript Techdegree Graduate 30,885 PointsThanks! If it makes any difference I had to run the rake db:migrate command with bundle exec, just FYI

36,441 PointsOK, it works on my machine and the first thing it wants me to do is log in. So I assume you have an old cookie where your database id was 3 and it was not removed properly. Try running the localhost in another browser or incognito tab to see if that does the trick. If it does, you have to clean your cookies.

Full Stack JavaScript Techdegree Graduate 30,885 PointsThank you very much!
Opening incognito did the trick. I will clear my cookies.

36,441 PointsGlad I could help. This knowledge will be useful for me in the future, I never encountered this problem before :).

12,548 PointsDid you copy the code exactly? It could be because your database isn't populated (for example, there is no user with the id of 3 if you haven't created any). If not I can go through with a finer comb!
