I'm new to Ruby on Rails (new to programming altogether) and this is my first post on stack overflow. I want to thank everyone in advance because I have learned so much from previous posts.
I completed the Micheal Hartl Ruby on Rails Tutorial but can't get it to launch successfully on Heroku even though it works perfect locally.
Iv done the following:
git push
git push heroku master
heroku pg:reset DATABASE
heroku run rake db:migrate
heroku run rake db:populate
(I have also done this without heroku restart with same results)
Things go wrong when I preform command: heroku run rake db:populate
Here is my heroku log

Please help, if you need any more information let me know. Thank you in advance.
Sounds to me like you didn't load the schema into your heroku database. After deploying what happens when you do this:
heroku run rake db:schema:load
Note that sometimes if you're loading up a new app that has an already-established schema, running all the migrations isn't the best way to get the database to the state you want - you should use rake db:schema:load instead. Let me know if this gets your database correct.
After running it you can use heroku run console and then do console commands like User.all to make sure it knows that the users table exists etc.
Don't forget to restart your server after loading the schema, or running db:migrate. For heroku that'd be: heroku restart
