Heroku rails deployement issues

currently i try to upload my rails app to heroku, but i am having this issues on my CLI:

2013-03-16T14:21:28+00:00 app[web.1]: Processing by PostsController#index as HTML
2013-03-16T14:21:28+00:00 app[web.1]: Completed 500 Internal Server Error in 1ms
2013-03-16T14:21:28+00:00 app[web.1]: 
2013-03-16T14:21:28+00:00 app[web.1]: NoMethodError (undefined method `accept' for nil:NilClass):
2013-03-16T14:21:28+00:00 app[web.1]:   app/controllers/posts_controller.rb:5:in `index'
2013-03-16T14:21:28+00:00 app[web.1]: 
2013-03-16T14:21:28+00:00 app[web.1]:

I am not very sure about what's going on here, this is my code for routes.rb and PostsController

routes.rb

Apps2::Application.routes.draw do

  devise_for :users, :controllers => { :omniauth_callbacks => "omniauth_callbacks" }

  resources :posts

  root :to => 'posts#index'
end

PostController

class PostsController < ApplicationController
  # GET /posts
  # GET /posts.json
  def index
    @posts = Post.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @posts }
    end
  end

  # GET /posts/1
  # GET /posts/1.json
  def show
    @post = Post.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @post }
    end
  end

  # GET /posts/new
  # GET /posts/new.json
  def new
    @post = Post.new

    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @post }
    end
  end

  # GET /posts/1/edit
  def edit
    @post = Post.find(params[:id])
  end

  # POST /posts
  # POST /posts.json
  def create
    @post = Post.new(params[:post])

    respond_to do |format|
      if @post.save
        format.html { redirect_to @post, notice: 'Post was successfully created.' }
        format.json { render json: @post, status: :created, location: @post }
      else
        format.html { render action: "new" }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # PUT /posts/1
  # PUT /posts/1.json
  def update
    @post = Post.find(params[:id])

    respond_to do |format|
      if @post.update_attributes(params[:post])
        format.html { redirect_to @post, notice: 'Post was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post = Post.find(params[:id])
    @post.destroy

    respond_to do |format|
      format.html { redirect_to posts_url }
      format.json { head :no_content }
    end
  end
end

Thanks.

The problem seems to be related to your database gem. Heroku uses PostgreSQL (pg) as it's database engine, not sqlite. Make sure you're using pg in production.

See: Undefined method 'accept' for nil:NilClass after upgrading to Rails 3

In my Gemfile I do:

group :development, :test do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
end
