Sinatra, accessing the environment variable & setting up databases

[doug livesey]

Hi -- any of the Sinatra buffs out there able to help me with a couple of issues?

I'm wanting to use Datamapper for my models, and *think* I'm okay with that, but I want to be able to set them up for testing, development, and production.

How do I access the environment variable? I mean to set and to get at any given point?

I want to be *very* sure the env is right before I run my cuke features, and that FactoryGirl isn't going to overwrite anything horrible.

Cheers,

   Doug.

this may be of interest to you

it covers some ENV variables in sinatra  - http://docs.heroku.com/rack

Interesting, thankyou.

It doesn't seem to cover where the deployment environment comes from, though.

For example, if you use a configure block, where does the app get the fact that it is in development mode (or test, or production) from?

I've dumped the ENV hash to the console, and still can't see any deployment environment info.

Hmm.

Cheers,

Im not sure that is actually available in Sinatra, so same on local as on production really..

I use Sinatra often, for ease, but if you want a full test suite and environments, rails comes into play...

It does have the configure blocks, where you can set app attributes depending on the environment, like so:

configure :development do

  @db_url = "postgres://usr:pwd@localhost"

end

So there must be a mechanism. I'll keep searching!

Cheers,

   Doug.

Hi Doug

I have just started working with Sinatra over the last week and have come across some of the same issues. I've written up a quick gist for you, though i haven't tested any of it :)

Cheers for that, Adam -- prompted by your gist, I've had a little success with Sinatra::Application.environment() and Sinatra::Application.environment=(), so I'll crack on with that.

Cheers again!

No Problem

By the way, the Sinatra Book[1] is a good resource, if you haven't come across it yet, not 100% finished tho

& apparently setting ENV["RACK_ENV"] before anything else will do it, too.
