First I would like to know if anyone has successfully built a Ruby on Rails application on Heroku using the XEROUND Add-on?

My PHP app works fine with the XEROUND Add-on (same database). My Ruby application however, errors on starting. We're sorry, but something went wrong.

On my development machine, When I run:

rails server -e production

the program starts with no problem.

When I push the code to Heroku and start the app I get the Were sorry error.

Any ideas? Is there anyway to output the database variables, right after they are assigned? As far as I know this would mean modifying the active-record adapter. Is this a problem with Ruby itself? Should it have even gotten into the connection pool? Would I be better off using XEROUND outside of Heroku (not as an Add-on)?

My database.yml contains

production:
  adapter: mysql2
  encoding: utf8
  database: <%= ENV['XEROUND_DATABASE_NAME'] %>
  username: <%= ENV['XEROUND_DATABASE_USERNAME'] %>
  password: <%= ENV['XEROUND_DATABASE_PASSWORD'] %>
  host:  <%= ENV['XEROUND_DATABASE_HOST'] %>
  port:  <%= ENV['XEROUND_DATABASE_PORT'] %>

I get the same message when I hardcode the values.

I did an internet search on: xeround heroku ruby

The first item on the list: https://devcenter.heroku.com/articles/xeround

So if I can use heroku config to set variables, then I should be able to see all variables Next search on: heroku config

The first item on the list: https://devcenter.heroku.com/articles/config-vars

In the config-vars article (from 2nd search) I can issue the command: heroku config

The first one caught my attention, its pointing to a postgres location. Does it matter? I'm not referencing DATABASE_URL.

The xeround article (from 1st search) contained a line, but didn't get into why, it just said do it.

Connecting to xeround The Xeround add-on will store the database’s URLs in two config vars: XEROUND_DATABASE_URL and XEROUND_DATABASE_INTERNAL_URL

The “internal” URL is translated to internal IP addresses and should be used when accessing your database from within the same datacenter. The first URL is used for connecting from outside.

Copy the value of the config variable that is relevant for you -

$ heroku config:add DATABASE_URL=(URL config vars)

Hmmm? It is not a variable I refrence in my program, nor is it set on my local machine.

Here it goes: Since this is supposed to be a cloud database, I should not need to know anything about datacenter locations, so going with external.

heroku config:add DATABASE_URL=mysql://app7912272:xxxx@instance27464.db.xeround.com.:16304/app7912272

DATABASE_URL: mysql://app7912272:XXXX@instance27464.db.xeround.com.:16304/app7912272

Lets see if it comes up.... Crap

Okay set it to internal:

heroku config:add DATABASE_URL=mysql://app7912272:xxxx@int.instance27464.db.xeround.com.:16304/app7912272

Lets see if it comes up.... Crap II

I also noticed there are two variables called XEROUND_DATABASE_ADAPTER, XEROUND_DATABASE_FAILOVER_ADAPTER and XEROUND_DATABASE_INTERNAL_ADAPTER. They are both set to mysql. I am using mysql2.

heroku config:add XEROUND_DATABASE_ADAPTER=mysql2
heroku config:add XEROUND_DATABASE_FAILOVER_ADAPTER=mysql2
herokU config:add XEROUND_DATABASE_INTERNAL_ADAPTER=mysql2

Lets see if it comes up.... Crap III

Further down in the article:

Each of the URLs contains a string of the following syntax:

mysql://username:password@host:port/database

The parts out of which the URLs are made of are also set for your convenience in the following environment variables:

XEROUND_DATABASE_ADAPTER
XEROUND_DATABASE_USERNAME
XEROUND_DATABASE_PASSWORD
XEROUND_DATABASE_HOST
XEROUND_DATABASE_PORT
XEROUND_DATABASE_NAME

XEROUND_DATABASE_INTERNAL_ADAPTER
XEROUND_DATABASE_INTERNAL_USERNAME
XEROUND_DATABASE_INTERNAL_PASSWORD
XEROUND_DATABASE_INTERNAL_HOST
XEROUND_DATABASE_INTERNAL_PORT
XEROUND_DATABASE_INTERNAL_NAME

Anyone who has been around programming long enough, probably knows where this is going. Sometimes you do things, even though they make no sense.

So the mysql: is derived from the adapter. Update the url variables as well:

heroku config:add DATABASE_URL=mysql2://app7912272:xxxx@instance27464.db.xeround.com.:16304/app7912272
heroku config:add XEROUND_DATABASE_URL=mysql2://app7912272:xxxxxx@instance27464.db.xeround.com.:16304/app7912272
heroku config:add XEROUND_DATABASE_FAILOVER_URL=mysql2://app7912272:xxxxxx@instance27464.db.xeround.com.:16304/app7912272
herokU config:add XEROUND_DATABASE_INTERNAL_URL=mysql2://app7912272:xxxxxx@instance27464.db.xeround.com.:16304/app7912272

No crap, the application came up

Since the mysql2 gem is the default w/ Rails 3 all you need to do is make sure you have "gem 'mysql2'" in your gemfile, and run bundle install, commit/push to heroku

Then of course use your URL listed in heroku config under "XEROUND_DATABASE_URL"

heroku config:add DATABASE_URL=mysql2://app7912272:xxxx@instance27464.db.xeround.com.:16304/app7912272

Note the changing the mysql:// to mysql2:// (this is the key)

Then

heroku restart

I JUST did this on a brand new Rails 3.2.9 Heroku app running Xeround with success. There was no need to change the adapter to "mysql2"
