Errno::ECONNREFUSED (Connection refused... in production environment - ruby-on-rails

I have finished my app and I am trying to check the production environment.
The app uses sunspot_rails gem for search. It works fine on the development server but it does not work on the production environment. My production logs gives the following:
Errno::ECONNREFUSED (Connection refused - {:data=>"fq=type%3AArticle&start=0&rows=1&q=%2A%3A%2A", :method=>:post, :params=>{:wt=>:ruby}, :query=>"wt=ruby", :headers=>{"Content-Type"=>"application/x-www-form-urlencoded; charset=UTF-8"}, :path=>"select", :uri=>#<URI::HTTP:0x007ff38e350578 URL:http://localhost:8983/solr/production/select?wt=ruby>, :open_timeout=>nil, :read_timeout=>nil, :retry_503=>nil, :retry_after_limit=>nil}):
app/controllers/articles_controller.rb:12:in `index'
How do I solve this issue ?
Here is my articles_controller:
class ArticlesController < ApplicationController
before_filter :require_login, except: [:show, :index]
def index
#search = Article.search do
fulltext params[:search]
paginate :page => params[:page], :per_page => 1
end
#articles = #search.results
##articles_by_month = Article.find(:all).group_by { |post| post.created_at.strftime("%B") }
end
def show
#article = Article.find(params[:id])
#comment = Comment.new
#comment.article_id = #article.id
end
def new
#article = Article.new
end
def create
#article = Article.new(article_params)
#article.save
redirect_to article_path(#article)
end
def edit
#article = Article.find(params[:id])
end
def destroy
#article = Article.find(params[:id])
#article.destroy
redirect_to articles_path
end
def update
#article = Article.find(params[:id])
#article.update(article_params)
flash.notice = "Article '#{#article.title}' Updated!"
redirect_to article_path(#article)
end
def article_params
params.require(:article).permit(:title, :body, :tag_list, :picture)
end
end
And here is my Gemfile:

How do I solve this issue ?

Have you started the solr instance in your production server?
bundle exec sunspot-solr start -p 8983

I dealt with some similar issues with Solr in the past. I made a script to handle launching it for me. It makes sure any crufty files that may affect access are cleaned up.
Hope this helps out!
See below:
pkill -f solr
#remove old data
rm -rf solr/data
rm -rf solr/default
rm -rf solr/development
rm -rf solr/pids
rm -rf solr/test
while getopts 'pdt' flag; do
case "${flag}" in
d) export RAILS_ENV=development ;;
p) export RAILS_ENV=production ;;
t) export RAILS_ENV=test ;;
*) error "Unexpected option ${flag}" ;;
esac
done
#startup solr
bundle exec rake sunspot:solr:start
echo "Solr started successfully."

While using rspec i am constantly getting the same error

I am getting the same Error on running rspec that is :-
"Undefined Method - authorize_manage_partner_links"
I am using CANCAN gem in my Gemfile for authorization purposes and i am using Rails version 3.2 and Ruby version 1.9.2.
Please suggest what to do as i am totally new to rspec and rails. I am using a testing database, on importing the database for the first time, when i am running rspec it is showing successful but after that it is showing this error on running the same rspec file. I am using FactoryGirl. and i have defined everything in my factoryrb file as well.
This is my controller--
require 'will_paginate/array'
class PartnerLinksController < ApplicationController
#load_and_authorize_resource
before_filter :authorize_manage_partner_links!
layout "backoffice"
def index
#partner_links = PartnerLink.all
if params[:sortby]
#partner_links = #partner_links.sort_by {|p| p.name} if params[:sortby] == "up"
#partner_links = #partner_links.sort_by {|p| p.name}.reverse if params[:sortby] == "down"
else
#partner_links = #partner_links.sort_by {|p| p.name}
end
total = #partner_links.size
#partner_links = #partner_links.paginate(:page => params[:page], :per_page => 20)
page = params[:page]
if !page
page = 1
end

end
end
def destroy

Error in users_controller_test after upgrading from rails 4

I have run through mhartls's rails tutorial a few times with rails 4.x and just for fun, I started again, but updating to rails 5.0.0.beta1.
I have managed to find solution to all of the incompatibilities up to chapter 9. Specifically, I can't get the test of the destroy action on the users controller to work. I get:
ERROR["test_should_redirect_destroy_when_not_logged_in", UsersControllerTest, 1.489256506320089]
test_should_redirect_destroy_when_not_logged_in#UsersControllerTest (1.49s)

test/controllers/users_controller_test.rb:48:in `block in <class:UsersControllerTest>'
bin/rails test test/controllers/users_controller_test.rb:47
my controller destroy action:
def destroy
User.find(params[:id]).destroy
flash[:success] = "User deleted"
redirect_to users_url
end
My test :
test "should redirect destroy when logged in as a non-admin" do
log_in_as(#other_user, integration_test: 'true')
assert_no_difference 'User.count' do
delete :destroy, params: { id: #user }
end
assert_redirected_to root_url
end
The links actually work, but test fails. I can get the test to pass by adding a route like this: delete 'delete_user' => 'users#destroy' AND changing the test to: delete delete_user_path params:{id: #user} however, the actual site and the test are using different routes, so I don't know if I can trust this. If I remove destroy from the users resources: resources :users, except: :destroy then the page link doesn't work but the test still passes. I don't see how to use the delete_user route on the page link and cant seem to get the user#destroy route to work in the test. I am aware that this is not an integration test, but this workaround fixed several other problems. I will refactor later, so that it makes sense.
Additional related controller code:
before_action :logged_in_user, only: [:index, :edit, :update, :destroy]
before_action :correct_user, only: [:edit, :update]
before_action :admin_user, only: :destroy
private
def user_params
params.require(:user).permit(:name, :email, :password,
:password_confirmation)
end
# Before filters
# Confirms a logged-in user.
def logged_in_user
unless logged_in?
store_location
flash[:danger] = "Please log in."
redirect_to login_url
end
end
# Confirms the correct user.
def correct_user
#user = User.find(params[:id])
redirect_to(root_url) unless current_user?(#user)
end
# Confirms an admin user.
def admin_user
redirect_to(root_url) unless current_user.admin?
end
Test Helper Code:
# Logs in a test user. (I think all tests must be like integration)
def log_in_as(user, options = {})
password = options[:password] || 'password'
remember_me = options[:remember_me] || '1'
# the next line is the work around for rails version >=5.1
integration_test = options[:integration_test] || 'false'
if integration_test == 'true'
post login_path, params: { session: { email: user.email,
password: password,
remember_me: remember_me }

else
# params[:session][:user_id] = user.id

The correct solution is to replace:
delete :destroy, params: { id: #user }
with:
delete user_url(#user)
It seems that my in current setup ( see gemfile etc.) tokens ( :destroy , :user, etc) are not handled the same as in my previous setup (like mhartl recommends) so the fix I use is to replace all of the tokens in my tests with named routes (:user becomes user_path(#user). The destroy action doesn't seem to have a default named route so I added one to the routes.rb file.
I can get the test to pass by adding a route like this:
delete 'delete_user' => 'users#destroy'
AND changing the test to:
delete delete_user_path params:{id: #user}
however, the actual site and the test are using different routes to the same action, so I don't know if I can trust this as a final solution.
If i remove destroy from the users resources:
resources :users, except: :destroy
then the page link doesn't work but the test still passes. I don't see how to use the added 'delete_user(#user) route' on the page link, I keep getting user not found when I try, and I cant seem to get the user#destroy action to work in the test without the added route.

Remove gem 'will_paginate', '~> 3.0' from group :development, :test do to gem 'will_paginate', '~> 3.0', group: :production and that corrected the NoMethodError message in the Heroku log.

ActiveModel Serializers: How do I serialize a resource collection?

I have a bookmarks resource and have mapped it to serve json by default under my api namespace like so in my routes.rb:
namespace :api, defaults: {format: 'json'} do
resources :bookmarks
get ':username', to: 'users#index'
get ':username/bookmarks/:id', to: 'users#show'
end
I have a Api::UsersController controller and a supporting BookmarkSerializer that works just fine on an individual bookmark resource like http://localhost:3000/api/emma_carter/bookmarks/87
But when I try to hit http://localhost:3000/api/emma_carter which is supposed to serve all bookmarks owned by the user, I get all different kinds of errors. Here is my Api::UsersController
module Api
class UsersController < ApplicationController
respond_to :json
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
render json: bookmarks
end
def show
user = User.find_by(username: params[:username])
bookmark = user.bookmarks.find_by(params[:id])
render json: bookmark
end
end
end
The show method works but the index method gives me ArgumentError in Api::UsersController#index
wrong number of arguments (1 for 0)
UPDATE: Full stack trace here: https://gist.github.com/amite/b79fc42bfd73de5a07bd

Here is the serializer:
class BookmarkSerializer < ActiveModel::Serializer
attributes :id, :url, :title, :domain, :notes, :image, :created, :username
belongs_to :user
def created
object.created_at
end
def username
user.username
end
end
Looking at other solutions on stack overflow, I have also tried other versions of my index method:
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
bookmarks.map { |bookmark| ::BookmarkSerializer.new(bookmark)}.to_json #updated line
end
This gives me the error:
Missing template api/users/index, application/index with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}.
Next the last version of my index method looks like this:
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
ActiveModel::ArraySerializer.new(bookmarks, each_serializer: ::BookmarkSerializer).to_json
end
This gives me the error uninitialized constant ActiveModel::ArraySerializer
What am I doing wrong? I am using rails 4.1.5 and the github version of the active_model_serializers
gem.
gem 'active_model_serializers', github: 'rails-api/active_model_serializers'
UPDATE: Since I am trying to output a collection of bookmarks I also tried using a separate serializer
BookmarksSerializer but I am getting the same error: ArgumentError in Api::UsersController#index
wrong number of arguments (1 for 0)
UPDATE2: Here is a version of the index method that kinda works in the sense that it renders the resource collection in json format:
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
respond_with bookmarks.to_json
end
But this still does not use the BookmarksSerializer
class BookmarksSerializer < ActiveModel::Serializer
attributes :id, :title
end
It just outputs the default hash

turns out I need to include v0.9 of the gem
gem 'active_model_serializers', github: 'rails-api/active_model_serializers', branch: '0-9-stable'
you could try change:
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
bookmarks.map { |bookmark| ::BookmarkSerializer.new(bookmark)}.to_json #updated line
end
to:
def index
user = User.find_by(username: params[:username])
bookmarks = user.bookmarks
render json: bookmarks.map { |bookmark| ::BookmarkSerializer.new(bookmark)}
end
