Hi all,
I’m loading fixture data via migrations into my application using the method described in the Agile book. This works beautifully for development and production environments. The only problem is, I don’t want these particular migrations to run when I do rake db:migrate RAILS_ENV=test. For one, there is no reason to being loading data into the test db. And, more problematic for me, this causes foreign key constraint errors which abort the rake with the test db because I’m using Redhillonrails’ foreign_key_migrations plugin.
Any tips?
Thanks!
Ryan

Yep, works perfectly. I had tried that but got the syntax wrong apparently. Thanks Jason!
Actually, I spoke too soon. This code doesn’t actually work. I thought it did because the argument passed, but it just ignored the migration on all environments. It seems that rake pulls RAILS_ENV from the actual setting in the application, not from the option passed at the command line (rake db:migrate RAILS_ENV=test), which only seems to change the db it’s acting upon. Someone tell me if I’m wrong.
I also tried this, which also skips the migration on all environments:
unless ENV[‘RAILS_ENV’] = “test”
migration stuff
end
and, the following caused all three environments to run the migration.
if ENV[‘RAILS_ENV’] = “development” || “production”
migration stuff
end
which I assumed was because the application is set to development. But for some crazy reason, this runs the migration on all environments as well!:
if ENV[‘RAILS_ENV’] = “production”
migration stuff
end
That, just doesn’t make sense. Anyone?

I've only 2 bytes for you :
Hints :
1/ any value not nil or false is true
2/ var = value returns value
Hahaha! Oh man… I was way over analyzing that one. Jeez… thanks for the Programming 101 kick in the arse Lionel. Step away from coding for a month and my mind goes to mush on the basics.
The winner:
unless ENV[‘RAILS_ENV’] == “test”
migration stuff
end
Puuuurfect.
Yeah, I’ll take partial responsibility for that, as I did only put in a single ‘=’ in my post. Sorry about that.
