I have a Ruby on Rails app and I want to deploy it on Heroku. Some errors appear and I think it is because the scaffolding order.
By that, I mean that a class named submissions is first created, but this class references another class named Users that is yet to be created.
This is the error that appears when doing rake db:migrate http://pastebin.com/R83a3rsN
And those are the migrate files and their filename
I guess you mean that:

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:
