Heroku 'Application Error' when running heroku

Question

I am trying to run my rails app on heroku. I have deployed successfully after doing an assets:precompile to get rid of some issues caused by bootstrap. I also have done a heroku run rake db:migrate. When opening my app I get an Application Error, specifically status=503 and error=H10.

Here is my heroku log

Edit:Here is the exact syntax error. It is a devise controller. It has not been altered since installing devise.

Answer 1

Naming

Indeed, the error appears to be thus:

/app/app/controllers/users/all_controller.rb:1: class/module name must be CONSTANT (SyntaxError)
class users::allController < Devise::allController

The problem is that you need to use a Constant name to define / call your controller. Currently, you're not doing this.

Simply, you'll need to do the following:

#app/controllers/users/all_controller.rb
class Users::AllController < Devise::AllController

This is important because Ruby (which Rails is built on), and most other software frameworks / languages in general, call constants at least by using CamelCase; most using FULL_CAPITALIZATION.

Looking at your controller definition, you're calling users::allController - neither CamelCase or CAPITALIZED.

Devise

Something else you need to consider is the role of Devise.

I've never seen the Devise AllController anywhere. I may be wrong, but I don't think it has one.

What you're doing is try to superclass a class which likely doesn't exist. So even if you resolve the naming issues with your controller, I believe you'll still hit a wall with the actual class itself.

Because you don't show us the contents of all_controller, I cannot give you any further recommendations. However, I can say that I believe you'll hit another error leaving it as it is.

Answer 2

Looks like the issue might be with one of your controllers when it tries to load it

app/controllers/users/all_controller.rb:1: class/module name must be CONSTANT (SyntaxError)

I pulled that out of the log, if you post some of that code, may be able to help further, but start by checking there
