How to solve NoMethod error in ROR-4 - ruby

Please help me to solve the following error. When I typed rake db:create in ruby cmd i got such type of error.
Error:

As I am new to ROR please help to solve this error and run the command successfully.I am using ruby version-1.9.3 and Rails version 4.0.2.

For me, it was a mistakenly uncommented comment line in the database.yml. For you, the format of your database.yml seems not right. Try and change the format of the following sections.
Replace
development:<<:*default
database:mysqlapp_development
with
development:
<<:*default
database:mysqlapp_development

Action Cable is not working with rails 5

I am a beginner in Rails 5 and I am trying to implement web sockets in my app. I am trying to copy and run a test app at first and I figure out it is not working as it is not transmitting and receiving the data. received: (data) -> is never called. I also observed that it never gets connected with my redis server either (which I installed with brew). I am pasting all the code below. Thanks in advance.
//room.coffee
App.room = App.cable.subscriptions.create "RoomChannel",
connected: ->
# Called when the subscription is ready for use on the server
disconnected: ->
# Called when the subscription has been terminated by the server
received: (data) ->
alert(data['message'])
speak: (message) ->
#perform 'speak', message: message
room_chanel.rb
# Be sure to restart your server when you modify this file. Action
Cable runs in a loop that does not support auto reloading.
class RoomChannel < ApplicationCable::Channel
def subscribed
stream_from "room_channel"
end
def unsubscribed
# Any cleanup needed when channel is unsubscribed
end
def speak(data)
ActionCable.server.broadcast "room_channel", message: data['message']
end
end

# Action Cable uses Redis by default to administer connections, channels, and sending/receiving messages over the WebSocket.
production:

test:
adapter: redis
url: redis://localhost:6379/1
cable.coffee
# Action Cable provides the framework to deal with WebSockets in Rails.
# You can generate new channels where WebSocket features live using the rails generate channel command.
#
# Turn on the cable connection by removing the comments after the require statements (and ensure it's also on in config/routes.rb).
#
#= require action_cable
#= require_self
#= require_tree ./channels
#
#App ||= {}
App.cable = ActionCable.createConsumer()
You might try to use Action Cable without Redis (since Redis is not strictly required for Action Cable):
development:
adapter: async
test:
adapter: async
production:
adapter: redis
url: redis://localhost:6379/1
But this probably is not the origin of your problem. Your room.coffee lacks some speak-calling code. Add to room.coffee something like this:
$ ->
$('#send_form').submit (event)->
App.room.speak event.currentTarget['message'].value
event.currentTarget['message'].value = ""
event.preventDefault()
false
Here's a template:
<div class="jumbotron">
<form id="send_form">
<label>Message:</label>
<input id="message" type="text" data-behavior="room_speaker">
<br>
<input type="submit" data-behavior="room_speaker">
</form>
</div>

Rspec suite fails running on AWS Ubuntu with ECONNREFUSED - but each test passes individually

We are trying to migrate our rails build from a local network server to an AWS EC2 instance running Ubuntu. The test suite works fine on all the developers machines (combination of mac and ubuntu) and the old build server (linux) but refuses to pass on the amazon instance.
The symptom is:
An error occurred in an after hook
Errno::ECONNREFUSED: Connection refused - connect(2)
occurred at /home/ubuntu/.rvm/rubies/ruby-2.0.0-p481/lib/ruby/2.0.0/net/http.rb:878:in 'initialize'
which is repeated a bunch of times. There is no error logged before this one.
However this issue only occurs when running multiple tests together (eg, bundle exec rspec) - when I run each test individually they all pass. Locally none of the dev team have seen this issue before.
Our tests use Selenium and Firefox which should run headless on ubuntu using Xvfb. We also use WebMock for some tests.
I have researched this issue for a day or two now and tried everything I can think of, to no avail. I have checked the versions of firefox and all the gems installed are the same on aws as locally.
My gemfile and spec_helper are below. I have investigated the firefox and xvfb installation, but because each test is able to pass individually I feel the system is generally ok ... but clearly something is not happy.

update
I have determined that the results are inconsistent between test runs. At first I thought it was the same each time, but the number of tests failing varies each run. I thought I had fixed the problem when all the tests passed except one, but the next run it was back to over a hundred failures.
update 2
Upon closer inspection (oops) I have discovered there were some tests failing with a different error the the majority. Instead of ECONNREFUSED, they are reporting 'End Of File Reached'. When I disabled these tests (5 in total) the remaining tests pass reliably. I suspect that xvfb is encountering some javascript or ajax related error, which is then preventing any of the following tests from passing. We are now working on diagnosing what is happening in these tests that is causing the failure.
File this one under 'not sure'. We ended up running up a new AWS server and setting it up again from scratch, and this time it worked fine. Some where suspect an issue with the javascript driver, possibly permissions related, but it is not worth our time investigating.

Heroku with ruby 1.9.3 causing many different crashes

I go to redeploy my heroku apps with a new gem in Gemfile and it crashes on startup
/app/vendor/bundle/ruby/1.9.1/gems/activesupport-3.2.3/lib/active_support/dependencies.rb:251:in `require': libruby.so.1.9: cannot open shared object file: No such file or directory - /app/vendor/bundle/ruby/1.9.1/gems/bcrypt-ruby-3.0.1/lib/bcrypt_ext.so (LoadError)
This is happening no matter what branch I deploy (old stable ones...) and only fixes by doing a heroku rollback.
I believe this is caused by heroku recently updating their ruby 1.9.3 because I was having this issue Heroku app crashes with 'libruby.so.1.9: cannot open shared object file' . Removing the nokogiri gem stopped the exception I was getting but then there's still this. More similar errors occur when I add new gems.
The whole problem was solved by deploying to a new heroku app but that's not something I can just do on my production server.
Any ideas on fixing the issue or somehow "refreshing" my app?
my gemfile:
source "https://rubygems.org"
ruby "1.9.3"
gem "rails", "3.2.3"
gem "thin"
# Bundle edge Rails instead:
# gem "rails", :git => "git://github.com/rails/rails.git"

# Deploy with Capistrano
# gem "capistrano"
# To use debugger
# gem "ruby-debug19", :require => "ruby-debug"
#
group :development do
gem "letter_opener"
end
Just FYI,
After contacting the Heroku support about this issue, you should follow these 3 simple steps:
Install this heroku-repo plugin: heroku plugins:install https://github.com/lstoll/heroku-repo.git
Run the following command: heroku repo:purge_cache
Deploy your app again.
Hope that helps!
This happened to me yesterday as well, was definitely something to do with Heroku.
I found fix and discussion on Twitter: https://twitter.com/bcardarella/status/256822171979100161
Just force-clear the gem file cache(clear gemfile, deploy, restore and deploy) and the app would start smoothly again.

RoR - ActiveRecord::ConnectionNotEstablished

I have generated an app using 'install bundle' and am getting the error ActiveRecord::ConnectionNotEstablished in the "About your application’s environment" page of the welcome aboard app.
The Gemfile
source 'https://rubygems.org'
gem 'rails', '3.2.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
any ideas?
This is the generated gemfile + changes to the version numbers of rails & sqlite-ruby selected by process of elimination to get the bundler to install everything.
Some Background
I am going through a book so suggestions about different versions are fine.
I don't know what I'm doing.
I'm using OSX 10.5 (leopard)
Let me know if there is any more information I should add.
Bonus question: If I need to start from scratch with a different sqlite version, should I create a new app or can I user the Bundler again?
edit
Kleber S. has suggested configuring the configure your config/database.yml file the file looks like:
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
development:
adapter: sqlite3
database: db/development.sqlite3
pool: 5
timeout: 5000
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: sqlite3
database: db/production.sqlite3
pool: 5
timeout: 5000
any ideas what's wrong?
you have probably to proper configure your config/database.yml file.
It may be necessary to create a new database on SQLite to fix that error.
bonus answer: you don't have to start it from scratch, just configure the database.yml file.
And what about just replacing this line :
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'
By this line :
gem 'sqlite3'
In your gemfile?
EDIT : ok, forget about this, MAC OS 10.5 can't use sqlite3. So the gemfile seems to be correct.

rails 3.1, why my coffee scripts not working?

I am trying to test coffee script in my rails 3.1 project, but it doesn't get executed, or generated as javascript in the application.js
I have a controller Page, here is the pages.js.coffee:
test = (input) ->
alert input
test 'hello'
but that alert never get executed at http://127.0.0.1:3000/pages,
in fact, the application.js is just empty!
here is the GemFile in case it would help:
source 'http://rubygems.org'
gem 'rails', '3.1.0'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
gem 'devise', '1.4.8'
gem 'will_paginate', '~> 3.0.2'
#gem 'nested_form', :git => 'git://github.com/fxposter/nested_form.git'
gem "simple_form"
gem 'kaminari'
gem 'foreigner'
gem "cocoon"
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
gem "jquery-rails"
gem 'coffee-script'
gem 'haml'
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
group :test do
# Pretty printed test output
gem 'turn', :require => false
end
EDIT
I have added those gems also and installed them, but, the coffee script is not executed
gem 'therubyracer'
gem 'coffee-script-source'
gem 'json'
gem 'execjs'
First: Having "coffee-rails" in your :assets group should be enough. Older versions had "coffee-script" in the :assets group.
Second: Where are you keeping your *.js.coffee files? You need to make sure they are in an "assets" folder some place. Start with app/assets/javascripts. If they aren't in your assets folder, they won't make it into the asset pipeline.
If you are doing that already, consider starting a new project and use the default configuration. It should work without any trouble. Compare the working project against the non-working project.
If all else fails, is it possible for you to share your project with us on GitHub?
Please check your config/application.rb, you should find a section like this:
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
#Bundler.require(:default, :assets, Rails.env)
end
I suspect you are not precompiling assets on deploy, even though you have it set to ignore the assets gems.
