Heroku Deployment Ruby on Rails log error (cannot find my column variable?)

I am trying to deploy a ruby on rails project to Heroku. I successfully did this the first time but then I was trying to update jquery-turbolinks and somehow the entire application will no longer launch. Instead I simply have "something went wrong" error. I've reverted everything back to the original code but it seems I still cannot launch the application. I've tried to bundle update and heroku run rake db:migrate but these do not seem to fix the problem.

heroku logs say:

User Controller Code: Can't seem to figure out what is wrong this was all working before with no problems. 

class UsersController < ApplicationController
  def index
    if flash[:errors]
      @errors = flash[:errors]
    end
    if flash[:success]
      @success = flash[:success]
    end
  end

  def show
    @user = User.find(params[:id])
  end

  def edit
    @user = User.find(params[:id])
  end

  def create
    @user = User.new(user_params)
    if @user.save
      flash[:success] = "User successfully created!"
      session[:user_id] = @user.id
      redirect_to '/mains'
    else
      flash[:errors] = @user.errors.full_messages
      redirect_to '/users'
    end
  end

  private
    def user_params
      params.require(:user).permit(:name, :email, :password,       :password_confirmation)
    end
end

The issue isn't to do with Heroku.

In your view code, you are referencing @user.id -- the error being returned ("ActionView::Template::Error (undefined method 'id' for nil:NilClass)") means that you are calling :id on nil -- which means @user is nil.

Check your controller code for where you are assigning @user and try to see why it might be empty. If you can't figure it out, edit your post to show the controller code.
