Add ability to create a feature in the UI

[midu]

Bring back ruby 1.8.7 compatibility

Rollout 1.1.0 is not compatible with ruby 1.8.7 and most of the code in rollout_ui does not take advantages of the changes brought by 1.1.0 so I took the liberty allowing the previous version.

(tests pass on both versions)

Feature#percentage returns 0

Because nil and 0% mean the same thing (here).

Remove ActiveRecord from the dummy app

So no database is needed for testing

Allow creation of a feature via Rollout UI

This is the main reason for this fork.

We needed a strategy to add a feature in rollout before pushing it from dev to prod (or other environments).

The choices were some rake task to run on deploy or adding the functionality to rollout ui. The latter allows non(-too)-tech people to do it as well and prevents having to ssh onto a server or deploy an app just to create a redis key.

The newly created feature is activated for no one.

It's definitely not as pretty as it could be but this is where my designer skills stop.

I'm a bit confused. Why is it needed to add a feature to an environment before deploy?

If the feature isn't added, it seems like it should behave cleanly:

• Deploy
• Feature is off as it doesn't exist in redis
• Turn feature on in RolloutUI
• Feature is on

Can you help me understand the use case for needing to populate redis prior to the deploy?

[jrallison]

Also, I'd prefer not to downgrade Rollout. What isn't compatible with ruby 1.8.7 in rollout 1.1? That may be an issue to fix in rollout itself.

[midu]

Well, the use case we have is this:

we will only hit a rollout.active?(:feature) after doing something a bit long to do (on staging) and that we can not do on production (eg: publish a challenge)

Until then, the feature key won't be in redis which means it won't be in rollout ui, which is a little bit problematic.

Ah, I see. I get it now. Thanks.

And the design maintainer for the UI is Holly, so she may be able to help. :)

[midu]

for the rollout version part, you're right. I'll see what I can do about it tomorrow

Hey @jrallison I think we are waiting on you to accept this pull request. No rush, just FYI :)

[midu]

@returntrue we're working on some issues on other pull requests

[returntrue]

OK fine I take it back

[jrallison]

Any word from Holly on design?

[KevinBongart]

Holly and I paired to make it look better. A pull request is open on Stefano's repo but still needs some love.
