how i can fix it?
Unix hosting, Ruby 1.8.7, Rails 2.3.5, MySQL 5.1.46
in mysql console all fine...
Try changing ":select => 'pass, login, id'" to :select => 'email, pass, login, id'; i.e. remove the backticks around the fields. I think the backticks in your argument are throwing off the select. Here is the API dock for the find command that lead me to that conclusion.

I'm trying to create a connection to mysql from ruby script using login path.
I've set the login path in the following way:
mysql_config_editor set --login-path=login-path --host=host-name --user=user --password
Now in my ruby script I have the following line:
require 'mysql2'
$mysql_connection = Mysql2::Client.new(:default_file => '~/.mylogin.cnf',:default_group => 'login-path')
And I get the following error:
error: Found option without preceding group in config file:
/home/user/.mylogin.cnf at line: 3 Fatal error in defaults handling.
Program aborted
When I'm connecting like this, it succeed:
require 'mysql2'
$mysql_connection = Mysql2::Client.new(:host => 'host-name', :username => "user", :password => "password", :database => 'database_name')
What am I doing wrong?
I think the problem is with your 'default_group' setting. I have standard mysql setup using a typical login-path of 'client', eg:
% mysql_config_editor print
[client]
password = *****
and the following connect works with no issue:
#client = Mysql2::Client.new(host: MySQL_Host, username: MySQL_User, default_group: 'client', database: MySQL_Database)
It seems like there are alot of tutorials online for using ruby to interact with mysql. But none of them work for me. Do I not have something installed correctly? Could someone tell me what I am doing wrong? I will try to put down as much relevant information as I can. I am relatively new to ruby (6 months).
This is my Error:

This is my sample script:
require 'rubygems'
require 'active_record'
ActiveRecord::Base.establish_connection(
:adapter=> "mysql",
:host => "localhost",
:database=> "#####",
:username => "#####",

end
Rubyist.create(:name => 'Luc Juggery', :city => "Nashville, Tenessee")
Rubyist.create(:name => 'Sunil Kelkar', :city => "Pune, India")
Rubyist.create(:name => 'Adam Smith', :city => "San Fransisco, USA")
I have the tables created in mysql. I am using the correct username, host, password, and database name. I have a table names Rubyist that has city and name columns.
gem list shows I have activerecord 4.1.1, mysql 2.9.1, mysql2 0.3.16

I want to add a second read-only database to my application based on a variable aside the SQLite file I'm developing with.
So, there should be three databases.
1. Local SQLite file
2. Production Read-only MySQL database
3. Test Read-only MySQL database
This test database has new columns added and will be pushed as production database soon.
From this SO-Q, I do not understand what the solution is.
I already use establish_connection.
establish_connection(
:adapter => 'mysql2',
:database => "db1",
:username => "username",
:password => "p*ssw*rd",
:host => "ho.st.com"
)
This db1 is the production db without the extra table columns.
db2 is the test db with the extra table columns.
establish_connection(
:adapter => 'mysql2',
:database => "db2",
:username => "username",
:password => "p*ssw*rd",
:host => "ho.st.com"
)
I thought this could be a solution:
In the models of the tables from the MySQL databases:
config = 'test'
case config
when 'test'
establish_connection(
:adapter => 'mysql2',
:database => "db1",
:username => "username",
:password => "p*ssw*rd",
:host => "ho.st.com"
)
else
establish_connection(
:adapter => 'mysql2',
:database => "db2",
:username => "username",
:password => "p*ssw*rd",
:host => "ho.st.com"
)
end
But now I have to edit all 'affected' models when I change the status. Is there a way to variabilise (is that even a word?) this so I only have to edit this config once?
I've tried via Application_controller.rb, but this didn't work.
# Application_controller.rb
def get_config_status
return 'test'
end
# model.rb
config = get_config_status() #=> undefined method `get_config_status' for Regio(Table doesn't exist):Class
# or
config = Application.get_config_status #=> uninitialized constant Regio::Application
Or should I consider totally something else?
To be honest, I don't like putting usernames and passwords in Models. Is this a possible thread for hackers?
Summary
What I'm trying to accomplish is:
Set one variable so my application uses db2 instead of db1.
The octopus gem might be helpful.
https://github.com/tchandy/octopus
You can select the database at query level,
User.where(name: 'Sam').using(:db2)
Or you can select the database per controller action,
class ApplicationController < ActionController::Base
around_filter :select_shard
def select_shard(&block)
Octopus.using(:db1, &block)
end
end
Check out the readme on Github for more examples.
I'm dealing with this a few days, and cannot connect to a simple mysql database on localhost.
require "mysql"
#db_host = "localhost"
#db_user = "myrubyapp"
#db_pass = "1234"
#db_name = "myrubyapp"
mysql = Mysql.new(:host => #db_host, :username => #db_user, :password => #db_pass, :database => #db_name)
The output I got is an error: can't convert Hash into String (TypeError) where Mysql.new is.
The second one, I tried to change the gem to mysql2
require "mysql2"
#db_host = "localhost"
#db_user = "myrubyapp"
#db_pass = "1234"
#db_name = "myrubyapp"
mysql = Mysql2.new(:host => #db_host, :username => #db_user, :password => #db_pass, :database => #db_name)
The output is an error too, but is different from the first: undefined method "new" for Mysql2:Module (NoMethodError).
Guys I'm sorry that I have to ask this kind of questions, but I'm really really confused, I have an experience of programming more than 3 years in JavaSE and EE, I am ashamed cause I can't deal with that. Please point me into right direction and don't judge me harshly. I am new to Ruby.
Try
mysql = Mysql2::Client.new(:host => #db_host, :username => #db_user, :password => #db_pass, :database => #db_name)
correct syntax is:
client = Mysql2::Client.new(:host => "localhost", :username => "root")
see mysql2 on github for more examples
I recomment you to take a look at Sequel as raw mysql2 lib provide a very limited functionality and Sequel can do a lot.
Never used the gem mysql, but have you tried to remove the hash :host => etc and pass directly a list of parameters?
Something like con = Mysql.new db_host, db_user, db_pass, db_name

I am using Rails 3.2.5 and exception_notification gem. In production mode, I am generally sending emails using PostMarkApp's postmark-rails gem.
Initially, I got a View error from exception_notification gem stating
ActionView::Template::Error (code converter not found (UTF-8 to UTF-16))
so based on exception_notification gem raises ActionView::Template::Error (code converter not found (UTF-8 to UTF-16)) only on Heroku production mode, I moved to
gem 'exception_notification', git: 'git://github.com/alanjds/exception_notification.git'
This solved that bug. Now, I want the gem to send emails from my gmail account instead of using PostMarkApp credits, so I added the following to my production.rb, yet Exception Notification attempts to send email only from Post Mark App. Why is this setting not working?
config.middleware.use ExceptionNotifier,
sender_address: 'noreply#mydomain.com',
exception_recipients: 'myemail#mydomain.com',
sections: %w{current_user} + ExceptionNotifier::Notifier.default_sections,
ignore_crawlers: %w{Googlebot bingbot},
email_format: true,
normalize_subject: true,
smtp_settings: {
:address => "smtp.gmail.com",
:port => "587",
:domain => "www.gmail.com",
:user_name => "myemail#gmail.com",
:password => "mypassword",
:authentication => "plain",
:enable_starttls_auto => true,
:openssl_verify_mode => 'none'
}
config.action_mailer.delivery_method = :postmark
config.action_mailer.postmark_settings = { :api_key => "_____" }
For some reason it appears that SMTP delivery does NOT work in the development environment. I tried a number of different settings and was never able to get this to work. It DOES however work in my other environments. Older posts seem to indicate this as well:
http://www.ruby-forum.com/topic/64776
http://www.devchix.com/2008/12/09/how-to-see-exception_notification-plugin-work-in-development-mode/
In development, I am using the following in my development.rb:
config.action_mailer.delivery_method = :letter_opener
config.middleware.use ExceptionNotifier,
:sender_address => 'test#test.com',
:exception_recipients => 'recipient#test.com'
In my "staging" environment, I am using the following in my staging.rb:
config.action_mailer.delivery_method = :smtp
config.middleware.use ExceptionNotifier,
:sender_address => 'test#test.com',
:exception_recipients => 'recipient#test.com'
The staging.rb acquires it's SMTP settings from an initializer I have the uses SendGrid for SMTP:
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => 25,
:domain => "test.com",
:user_name => "user_name",
:password => "password",
:authentication => "plain"
}
