I have tried bundle install and also tried to change the PATH but it doesnt recognise it as internal variable, don't know how to fix this.
Any suggestions ?
Thank you.
First you must install the logstash input plugin by running
bin/logstash-plugin install logstash-input-jdbc
And also If it does not help,
try
Java::com.mysql.jdbc.Driver
instead of the
com.mysql.jdbc.Driver
for the jdbc_driver_class. I had a same kind of problem with oracle when I did not use the
Java::
before the oracle.jdbc.OracleDriver as the jdbc_driver_class.

I am trying to run a system test which touches a model which requires a file from the /lib directory. The file loads fine and the code works fine on localhost in development mode, but as soon as I run the test it errors with:
Error:

Excerpt from the model, order.rb, that requires the file is:
require "pago"

If i run rails console require 'pago' returns true. I don't see any clues in the various config and environment files as to what the problem might be. The tutorial code seems to be char by char the same as mine. I just can't work out what's oging wrong here. Can anyone help?

You have to use the mysql2 adapter for your connection string. That also means you have to install the mysql2 gem on your machine. Make sure you have the MySQL development package on your machine and build essentials since this gem is a native extension and has dependencies outside Ruby.
Then connect via:
sequel -m db/migrations/ mysql2://root:root#localhost/todo
I have included given code in my db.rb file
require "mysql2" # if needed
#db_host = "localhost"
#db_user = "root"
#db_pass = "root"
#db_name = "farji"
client = Mysql::Client.new(:host => #db_host, :username => #db_user, :password => #db_pass, :database => #db_name)
#cdr_result = client.query("SELECT * from employee')
and in terminal i have install
sudo apt-get install libmysqlclient15-dev
gem install mysql2
and run ruby db.rb it gives me error db.rb:8:in `': uninitialized constant Mysql (NameError)
my ruby version is ruby-2.1.5
Please guide me how to solve this.
I'm trying to work with activerecord and mysql without using rails, but I can't seem to connect my ruby code to mysql. My guess is i'm doing something wrong with my require statement or with how my gems are installed. Below is:
A. my script
B. my local gem list showing that the gems are installed
C. my path variables
D. my gem environment and
E. the error message i'm getting
Please help, this has consumed my entire day!
(I have activerecord-mysql-adapter showing in jewelry box under my ruby-1.9.3-P327#rails3tutorial2ndEd option, but not in my terminal when I run gem list --local. Could that have anything to do with it?)
(I also tried the solution sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib from this question and it didn't work for me.

Have you tried to change
:adapter => 'mysql'
to
:adapter => 'mysql2'
change adapter mysql2
development:
adapter: mysql2
database: library_development
username: root
password:
host: localhost
test:
adapter: mysql2
database: library_test
username: root
password:
host: localhost
production:
adapter: mysql2
database: library_production
username: root

host: localhost
I've been trying to use mysql and active record on a ruby script but I'm getting the following message: Outdated mysql gem. Upgrade to 2.8.1 or later. In your Gemfile: gem 'mysql', '2.8.1'. Or use gem 'mysql2' (RuntimeError). Before I was getting a message about gem 'mysql2' missing but then i checked the source code on the connection adapters in active record and saw that it require mysql gem which i didnt have installed.
this is my script:
require 'rubygems'
require 'active_record'
require 'mechanize'
require 'nokogiri'
require 'active_record'
require 'mysql2'
gem 'mysql2'
ActiveRecord::Base.establish_connection ({
:adapter => "mysql",
:host => "localhost",
:username => "root",
:password => "",
:database => "rainalytics"})
ActiveRecord::Schema.define(:version => 20110320035328) do
create_table "score_logs", :force => true do |t|
t.integer "blog_posts"
t.integer "featured"
end
create_table "users", :force => true do |t|
t.datetime "created_at"
t.datetime "updated_at"
end
end
class User < ActiveRecord::Base
has_many :score_logs
end
class ScoreLog < ActiveRecord::Base
belongs_to :user
end
Im not using the 'require 'mysql2' or 'gem 'mysql2' parts, and it seems to be working fine, I also have additional {} inside the ActiveRecord::Base block
hope this can help someone in future :)
This is what I use
ruby 1.9.2p318 (2012-02-14 revision 34678) [x86_64-darwin11.2.0]
Rails 3.1.0
require "rubygems"
require "active_record"
ActiveRecord::Base.establish_connection ({
:adapter => "mysql2",
:host => "localhost",
:username => "root",
:password => "root",
:database => "cybercellar"})
class Zone < ActiveRecord::Base
end
zone = Zone.all
print zone
then I navigate to my app folder and run the file
ruby script/test.rb
