ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR: relation “guestbooks” does not exist

Question

I continue to get this error message in my Papertrail logs when I try to access my URL /guestbooks.

This route works great on localhost, but not on Heroku. Are my rails naming conventions off? I think they are right, but I could be mistaken.

I tried running rake db:rest , I then tried running rake db:drop db:create db:migrate , which showed that I was getting errors in my migration files, so I deleted them and then ran the command again and no longer received the migration files error from PG.

I tried committing my changes and running heroku run rake db:migrate , but my error persisted. Below are my MVC and routes.

    class GuestbooksController < ApplicationController
    before_action :load_page

    def index
        @guestbook = Guestbook.new
    end

    def create
        @guestbook = Guestbook.new(guestbook_params)

        if @guestbook.save
            flash.now[:notice] = "Thanks for taking the time to write us! We greatly appreciate it!"
            render :index
        else
            flash.now[:notice] = "Your message failed to post, please try again"
            render :index
        end
    end

    private

    def load_page
        @guestbooks = Guestbook.page(params[:page])
    end

    def guestbook_params
        params.require(:guestbook).permit(:name, :email, :message)
    end
end

My schema

  create_table "guestbooks", force: :cascade do |t|
    t.string   "name"
    t.string   "email"
    t.text     "message"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

My model

class Guestbook < ActiveRecord::Base
    paginates_per 5
end

The issue was that I didn't have any migrations (only schema.rb). You can remove all migrations if you want, but if you do, you need to run rake db:setup to use schema.rb to setup the database (rake db:reset will only look for migrations).
