require "rubygems"
require "tiny_tds"
client = TinyTds::Client.new(:username => 'sa', :password => '', :host => 'RICHARD_PC\SQLEXPRESS')
result = client.execute("SELECT * FROM [Contacts]")
result.each do |row|
//Do something
end
I keep getting the same error: "Connect: Server name not found in the configuration files". All I need to do is to be at least be able to connect with Sql Server. So if the host is not the sqlexpress instance installed on my machine, what is it then? In the Github website it said this host => 'mydb.host.net' (:host - Used if :dataserver blank. Can be an host name or IP.)
Thanks for helping.
Either use
:dataserver => 'RICHARD_PC\SQLEXPRESS'
Or use
:host => 'RICHARD_PC', :port => 1433
For those running rails on vagrant, I got this error when my vagrant network connections stopped working (mostly just the DNS), so a reboot fixed the issue.

I'm trying to enable SSL for my thin server web app so that it can work over HTTPS.
I have done the following:-
launching of thin web server
MyApp.run! :host => '127.0.0.1', :port => 9090, :sslenable => true, :sslverifyclient => OpenSSL::SSL::VERIFY_NONE,
:sslcertificate => '.ssl/server_key.pem', :sslprivatekey => '.ssl/key.pem'
I generated a self signed certificate and private key using the openssl module in Ruby, created a directory called .ssl and stored them there as pem files.
The web framework I'm using for my web app is Sinatra. I'm also using the rack-ssl gem in the following way..
myapp.rb
require 'rack/ssl'
class MyApp < Sinatra ::Base
use Rack::SSL
use Rack::Session::Cookie,
:key => '_rack_session',
:path => '/',
:expire_after => 2592000,
:secret => ''
...
end
When I go to http://localhost:9090, I would expect to see my app displayed as normal but with a padlock and a cross through it as any http request is being redirected to https and I see the error "webpage is not available". However when I remove ssl-rack ruby gem and restart my app and go to https://localhost:9090,i get an ssl connection error with the following details:
Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
Error code: ERR_SSL_PROTOCOL_ERROR
Can anyone please advise me on how best to configure a thin server to enable SSL?
I'm running Sinatra and Thin on Heroku with SSL using the Rack::SslEnforcer, doing this:
if production?
require 'rack/ssl-enforcer'
use Rack::SslEnforcer
end
This should be before you enable :sessions in your file. So, Rack::SslEnforcer needs to be placed above the session part when you configure your app.
Somewhat unrelated, but perhaps still relevant, you might consider adding:
require 'encrypted_cookie'
cookie_config = {
:key => 'usr',
:path => "/",
:expire_after => 86400, # one day in seconds
:secret => ENV["COOKIE_KEY"],
:httponly => true
}
cookie_config.merge!( :secure => true ) if production?
use Rack::Session::EncryptedCookie, cookie_config
You also need to set the COOKIE_KEY in your environment to something secret and long-ish.
I downloaded the postgres.app for my Mac OSX machine. I have a rails app that has connected and used the postgres DB that came with the postgres app.
Now I am writing a pure Ruby test script (Not Rails, pure Ruby, not even Active Record) to try to connect to the postgres database instance. These are the steps I followed to set this up
1) ran this command on the terminal:
gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config
2) Added this code to the test script:
#!/usr/bin/env ruby
#encoding: utf-8
require "pg"
#conn = PG.connect(
:dbname => 'oData',
:user => 'am',
:password => '')
#conn.exec("CREATE TABLE programs (id serial NOT NULL, name character varying(255);");
I got this from this link
When I ran this script I get the following error:
/Users/am/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.16.0/lib/pg.rb:38:in `initialize': could
not connect to server: No such file or directory (PG::ConnectionBad)
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
My Debug efforts:
My postgres.app is up and running.
I looked at the pg gem [documentation][2] and my syntax seemed OK.
The location of my postgres DB is entered in my bash script like so
PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"
Not sure what to do next. Any help would be appreciated, Thanks.
are you sure postgres is listening on a socket? are you sure the username and password is right?
I would be inclined to try something like
require 'pg'
puts PG::Connection.ping(:dbname => 'oData',:user => 'am',:password => '')
puts "trying with tcp"
puts PG::Connection.ping(:dbname => 'oData',:user => 'am',:password => '', :port => 5432)
I used active record gem to make the connection work and it was fine
Settings to connect works for me.
But that code should look like
#conn.exec("CREATE TABLE programs (id serial NOT NULL, name
character(255))")
I have to send weekly emails to all the user about the latest things happening. I am using ActionMailer to accomplish other mailing task however I have no clue how to automate the weekly emails.
Update
I found whenever gem which could be used to schedule cron jobs. I guess this could be used to send weekly emails which I intend to. Still looking how to make it work with ActionMailer will update once I find the solution
Update 2
This is what I have done so far using whenever gem:-
in schedule.rb
every 1.minute do
runner "User.weekly_update", :environment => 'development'
end
in users_mailer.rb
def weekly_mail(email)
mail(:to => email, :subject => "Weekly email from footyaddicts")
end
in users.rb
def self.weekly_update
#user = User.all
#user.each do |u|
UsersMailer.weekly_mail(u.email).deliver
end
end
If i try to run User.weekly_update from the console I am able to get the mails. I am testing in development mode and using rvm. I checked my crontab file and it has got the right stuff.
However I am not getting any mails automatically from the app. Any clue what might be wrong?
Thanks,
OK so it turns out to be a path issue with whenever gem, and the problem was created when I installed another version of ruby.
In my machine the new ruby version is installed in /usr/local/bin/ruby. In my rails app I had to go to the file script/rails and replace #!/usr/bin/env ruby with #!/usr/local/bin/ruby.
I found this out by visiting cron.log file which showed this error message :- /usr/bin/env: ruby: No such file or directory
I made a cron.log file to log the cron error this is what I did in my schedule.rb code written in the question :-
every 2.minutes do
runner "User.weekly_update", :environment => 'development', :output => 'log/cron.log'
end
I am getting periodic mails now.
It seems like you haven't configured ActionMailer settings.
First check out the logs from console, whether the mailing process is working(paste your logs).
If yes then do following steps.
add this in your gemfile.
gem 'tlsmail'
run
bundle install
write these configuration setting in your config/environments/development.rb file
require 'tlsmail'
Net::SMTP.enable_tls(OpenSSL::SSL::VERIFY_NONE)
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.perform_deliveries = true
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => "587",
:domain => "gmail.com",
:enable_starttls_auto => true,
:authentication => :login,
:user_name => "<address>#gmail.com",
:password => "<password>"
}
config.action_mailer.raise_delivery_errors = true
add your working password/email against user_name and password.
Don't forget to restart server.
I'm trying to define a custom port for the ssh connection using Net::SCP, but without luck so far.
Here's an example how I'm trying to download a remote file from a server with a custom ssh port:
require "rubygems"
require 'net/scp'
Net::SCP.download!("www.server.com", "user", "/opt/platform/upload/projects/file.txt", "/tmp/bb.pdf",{:password => "mypassword",:port => 22202})
The error message I'm getting is:
Errno::ECONNREFUSED: Connection refused - connect(2)
There are no entries in the server logs regarding the ssh connection, so I assume that Net::SCP isn't using my custom port.
Any tips for me ?
Regards, Alex
Well, I've found the solution myself.
require "rubygems"
require "net/scp"
Net::SSH.start("www.myserver.com", "theuser", {:password => "whateverpwd",:port => 22212}) do |ssh|
ssh.scp.download! "/opt/platform/upload/projects/my.pdf", "/tmp/bb.pdf"
end
I also keep SSH on a non-standard port and use SCP like so:
Net::SCP.upload!( "foo.net", "user", the_file, the_file, :ssh => { :keys => #keys, :port => the_port } )
Works like a champ. I also use key-based authentication, hence the keys parameter getting passed along with the port.
I use selenium, usually with firefox, to test my rails apps and it's all fine. I want to run my tests in IE6 as well. I'm in ubuntu, using the ruby selenium-client gem. For IE6 i use ies4linux, this is an executable which is at /home/max/.ies4linux/bin/ie6
I'm editing my selenium conf to try to get it to use the above, but can't get it working. Here's what i have at the moment:
SELENIUM_CONF = {
:client_options => {
:url => "http://awebsite.com",
:host => "localhost",
:port => 4444,
:browser => "*iexplore /home/max/.ies4linux/bin/ie6",
:javascript_framework => :jquery
}
}
Then when i make a browser in my scripts i call
Selenium::Client::Driver.new(SELENIUM_CONF[:client_options])
It's not happy with what i have in the :browser field at the moment - i get this error:
"Failed to start new browser session: Error while launching browser"
I also tried
:browser => "/home/max/.ies4linux/bin/ie6",
But got a "Browser not supported" error as it expects one from list, *iexplore in this case.
Can anyone tell me how i can get this working?
thanks, max
I don't think there's a way to do that. Selenium uses iehta, and some not-so-used parts of ie that could not be bundled in ie4linux, and even if there were, I wouldn't trust on a test that runs IE under linux.
Why not creating a VM using VirtualBox and pointing your tests to an RC server inside the VM?
