Heroku Rails Migration error

Question

I finished creating user sign-up for my new rails app and everything worked fine in development on my local machine. But on heroku the deployed app will not load the signup_path which renders "new.html.erb". Clicking this path gives me an error telling me to check my logs.

I've checked the logs and have tried several things but don't know what to do now. Here are the logs: http://pastebin.com/v1fVqLbL

The error is:

ActionView::Template::Error (undefined method `phone' for #<User:0x007f05a265c030>):

I've tried rolling back my migrations using heroku run rake db:rollback but can't seem to actually any of the migrations to rollback because heroku rake db:status still gives me the last (index to phone numbers) as the current.

Getting this error sometimes when trying to rollback:

User.rb

class User < ActiveRecord::Base
  before_save { self.email = email.downcase }
  validates :name, presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
                    format: { with: VALID_EMAIL_REGEX },
                    uniqueness: { case_sensitive: false }
  VALID_PHONE_REGEX = /\A(\+\d{1,2}\s)?\(?\d{3}\)?[\s.-]?\d{3}[\s.-]?\d{4}\z/
  validates :phone, presence: true, length: {maximum: 15},

                    uniqueness: true
  has_secure_password
  validates :password, length: { minimum: 6 }
end

My production schema, where I believe phone is defined:

ActiveRecord::Schema.define(version: 20150204094519) do

  create_table "users", force: :cascade do |t|
    t.string   "name"
    t.string   "email"
    t.datetime "created_at",      null: false
    t.datetime "updated_at",      null: false
    t.string   "password_digest"
    t.string   "phone"
  end

  add_index "users", ["email"], name: "index_users_on_email", unique: true
  add_index "users", ["phone"], name: "index_users_on_phone", unique: true

end

Heroku Migrations:

Happy to add any other files if necessary. I'm running the final gemfile from Hartl's newest tutorial. Don't know what else to do

Answer 1

My problem was that git wasn't tracking any of the sessions files I had added, so they were on my local computer but not on github->heroku. I found this out by making a change only on sessions_helper, then committing to git only to get a message that there were no changes to any files but several (all of the sessions files) were untracked.

This happened because I used git -am "commit message" rather than git add -A first bc I thought the -a flag added everything. Should've checked git to make sure sessions_helper.rb was there, all the answers told me to check this but I was only checking on my local machine.
