Bundler.require(:default) fails in Rubinius - ruby

I have a very simple app, which i tried to run with Rubinius:
Gemfile:
source 'https://rubygems.org
gem 'rake'
gem 'tiny_tds'
gem 'sequel'
lib/database.rb:
require "rubygems"
require "bundler/setup"
Bundler.require(:default)
DB = Sequel.tinytds(:host => 'SQL2012', :user => "Rails", :password => "xxx", :database => "RailsTest")
test/connection_test.rb:
require_relative "../lib/database"
DB.fetch("SELECT TOP 10 * FROM User") do |row|
puts row.to_s
end
Rakefile:
require 'rubygems'
require 'rake'
require 'rake/clean'
require 'rake/testtask'
Rake::TestTask.new do |t|
t.test_files = FileList['test/**/*.rb']
end
task :default => :test
This runs fine with MRI 1.9.3 and MRI 2.1.0
but fails with rbx 2.2.2 :
klaus#rails-dev:$ rake test

You probably need to add bigdecimal or rubysl to your Gemfile. rubinius has gemified their stdlib, causing issues similar to this one.

sinatra activerecord doesn't find model on heroku

I have a classic style sinatra app (not modular), using sinatra-activerecord.
This is my config.ru
require 'rubygems'
require 'bundler'
Bundler.require
require './config/environment'
require './babycomptes' # main application file
run Sinatra::Application
and config/environment.rb:
APP_ENV = ENV["RACK_ENV"] || "development"
ENV['SINATRA_ENV'] ||= "development"
require 'require_all'
require 'bundler/setup'
Bundler.require(:default, ENV['SINATRA_ENV'])
require_all 'app'
The main app file (babycomptes.rb) is sitting at the root of my project. It contains:
require 'sinatra'
require 'sinatra/namespace'
require 'sinatra/activerecord'
require 'bcrypt'
require 'securerandom'
require_relative './app/helpers/helpers.rb'
# Dir["./app/models*.rb"].each {|file| require file }
get '/signup' do
erb :'signup/new'
end
post '/signup' do
#user = User.new(params[:user]) # this is line 51
# cut for brievity
end
The app works fine when I rackup locally and when I run heroku local, but runs into an error on heroku :
2020-12-30T06:20:27.936954+00:00 app[web.1]: 2020-12-30 06:20:27 - NameError - uninitialized constant User:
2020-12-30T06:20:27.936967+00:00 app[web.1]: /app/babycomptes.rb:51:in `block in <top (required)>'
no clue where to start looking....

uninitialized constant ActiveRecord::ConnectionAdapters::ConnectionManagement

Im currently working on a sinatra app, and im having a trouble regarding postgresql connection to sinatra, im try to execute this command:
rake db:create
to create the database but it throws this error.
C:\Users\John\Documents\Registration_Sinatra>rake db:create
rake aborted!
NameError: uninitialized constant ActiveRecord::ConnectionAdapters::ConnectionManagement
C:/Users/John/Documents/Registration_Sinatra/app/app.rb:2:in `<top (required)>'

C:/Users/John/Documents/Registration_Sinatra/Rakefile:1:in `<top (required)>'
(See full trace by running task with --trace)
this is my app.rb
require 'sinatra'
require 'sinatra/activerecord'
require 'pg'
require './config/environments'
class RegistrationSinatra < ActiveRecord::Base
end
get '/' do
erb :index
end
this is my environments.rb
configure :development do
#DEFAULT_CONN = {database: 'development_registration_sinatra', user: 'postgres', password: 'secret123', host: 'localhost'}
db = URI.parse(ENV['DATABASE_URL'] || "postgres://#{#DEFAULT_CONN[:host]}/#{#DEFAULT_CONN[:database]}?user=#{#DEFAULT_CONN[:user]}")
ActiveRecord::Base.establish_connection(
:adapter => db.scheme == 'postgres' ? 'postgresql' : db.scheme,
:host => #DEFAULT_CONN[:host],
:username => #DEFAULT_CONN[:user],
:password => #DEFAULT_CONN[:password],
:database => db.path[1..-1],
:encoding => 'utf8')
end
this is my gemfile
source 'https://rubygems.org'
ruby "2.2.2"
gem 'sinatra'
gem 'activerecord'
gem 'sinatra-activerecord'
gem 'tux'
gem 'pg'
and my Rakefile
require './app/app'
require 'sinatra/activerecord/rake'
hope you guys can pin point what's wrong with my sample app so i can progress thanks.
Here is the solution: https://github.com/janko-m/sinatra-activerecord/pull/66
In your Gemfile, add:
gem "activerecord", "< 5.0.0"
run bundle update and it will work.

undefined method `namespace' for main:Object (NoMethodError) - active record / rakefile

I'm attempting to run a basic Sinatra app. When I get to the 'rackup' step I get an error:
/.rvm/gems/ruby-2.2.1/gems/activerecord-4.2.1/lib/active_record/railties/databases.rake:3:in `<top (required)>': undefined method `namespace' for main:Object (NoMethodError)
It seems to be a scope issue in the Rake gem. I've had no luck findding an answer and I'm not quite sure what needs to be fixed. I did update all my gems in hopes that would help to no avail. Here is my code that might be contributing....
rakefile.rb
require "./frank"
require "sinatra/activerecord/rake"
config.ru
require_relative 'frank'
map('/welcomes') { run WelcomesController }
frank.rb
require 'sinatra/base'
require 'active_record'
require 'bcrypt'
Dir.glob('./{controllers,models}/*rb').each { |file| require file }
ENV['SINATRA_ENV'] ||= 'development'
ActiveRecord::Base.establish_connection(
:adapter => 'sqlite3',
:database => "db/#{ENV['SINATRA_ENV']}.sqlite"
)
spec_helper.rb
ENV['SINATRA_ENV'] = 'test'
require_relative '../frank'
require 'capybara'
require 'database_cleaner'
Capybara.app = Rack::Builder.parse_file(File.expand_path('../../config.ru',__FILE__)).first
RSpec.configure do |config|
config.include Capybara::DSL
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
Many thanks :)
This is below the primary error:
from /Users/stephaniedean/.rvm/gems/ruby-2.2.1/gems/sinatra-activerecord-2.0.6/lib/sinatra/activerecord/rake.rb:1:in `load'
from /Users/stephaniedean/.rvm/gems/ruby-2.2.1/gems/sinatra-activerecord-2.0.6/lib/sinatra/activerecord/rake.rb:1:in `<top (required)>'
So, it looks like sinatra-activerecord not just activerecord. I did try activerecord 3.2.17 that didn't work. Thanks for the suggestions.
this took up hours of my time before I found the solution:
http://aaronlerch.github.io/blog/sinatra-bundler-and-the-global-namespace/
https://github.com/sinatra/sinatra-contrib/issues/111
Gemfile
gem "sinatra", require: 'sinatra/base'
gem 'sinatra-activerecord', require: false
gem 'sinatra-contrib', require: false
Environment.rb
require 'bundler/setup'
require 'rake'
require 'sinatra'
require 'sinatra/reloader'
require 'sinatra/activerecord'
require 'sinatra/activerecord/rake'
make sure to
require 'rake'
before
require 'sinatra/activerecord/rake'

Mongoid error in heroku: Database should be a Mongo::DB, not a nil class

I have a Sinatra app on heroku and it keeps crashing due to this error:
app/vendor/bundle/ruby/1.9.1/gems/mongoid-1.2.14/lib/mongoid/config.rb:52 in 'master': Database should be a Mongo::DB, not a nil class
I set up Mongoid 3.x according to the heroku instructions, and the app works on my local machine, so I'm not sure what's causing this problem. My gemfile looks like this:
source "https://rubygems.org"
ruby "1.9.3"
gem 'sinatra'
gem 'mongo'
gem 'mongoid'
gem 'bson_ext'
gem 'json'
gem 'nokogiri'
gem 'aws-s3', '0.6.2', :require => 'aws/s3'
gem 'sinatra-reloader'
gem 'debugger'
gem 'thin'
Here's my mongoid.yml:
development:
sessions:
default:
database: db
hosts:
- localhost:27017
production:
sessions:
default:
uri: <%= ENV['MONGOHQ_URL'] %>
options:
skip_version_check: true
safe: true
And here's my app file:
require 'bundler/setup'
require 'sinatra'
require 'json'
require 'mongo'
require 'mongoid'
Mongoid.load!('mongoid.yml', :production)
def get_connection
return #db_connection if #db_connection
db = URI.parse(ENV['MONGOHQ_URL'])
db_name = db.path.gsub(/^\//, '')
#db_connection = Mongo::Connection.new(db.host, db.port).db(db_name)
#db_connection.authenticate(db.user, db.password) unless (db.user.nil? || db.user.nil?)
#db_connection
end
db = get_connection
class Model1
include Mongoid::Document
field :name, :type => String
end
I shouldn't have to specify a database name since I'm using the uri field, so I'm not sure why the database if nil?

Simple use of EM::Synchrony#sync causes 'root fiber' FiberError -- my fault?

This program
require 'em-synchrony' ## v1.0.0
require 'em-hiredis' ## v0.1.0
module EventMachine
module Hiredis
class Client
def self.connect(host = 'localhost', port = 6379)
conn = new(host, port)
EM::Synchrony.sync conn.connect
conn
end
alias :old_method_missing :method_missing
def method_missing(sym, *args)
EM::Synchrony.sync old_method_missing(sym, *args)
end
end
end
end
EventMachine.synchrony do
redis = EM::Hiredis.connect
redis.set('foo', 'bar')
puts redis.get('foo')
EM.stop
end
dies like this

I find this deeply confusing. Why doesn't it work and am I at fault? If so, what can I do differently? Unless I've glossed over something, this is kosher, per the em-synchrony README.
I think your code can work if you find the correct version of em-hiredis it is trying to monkey patch, that is one problem with loose dependencies.
Here is a fully working code but based on the master branch of em-synchrony:
Gemfile:
source :rubygems
gem 'em-synchrony', :git => "git://github.com/igrigorik/em-synchrony.git"
gem 'em-hiredis', '~> 0.1.0'
test.rb:
require 'rubygems'
require 'bundler/setup'
require 'em-synchrony'
require 'em-synchrony/em-hiredis'
EventMachine.synchrony do
redis = EM::Hiredis.connect
redis.set('foo', 'bar')
puts redis.get('foo')
EM.stop
end
and then run it with:
$ bundle
$ ruby test.rb
Monkey patching is an inherently flawed way of patching gems unless you ensure the exact version of the gem you patched is used which is something em-synchrony should enforce or at least detect.
