Integration with Rails 5

[janraasch]

Hi there, Happy New Year!

Currently, when trying to install this together with rails v5.0.0.beta1, bundler will install

  * sinatra-1.0.gem
  * delayed_job_web-1.2.5.gem

since 1.0 is the only version of sinatra which does not restrict itself to rack v1.x, "< 2", and rails v5.0.0.beta1 runs on rack 2.0.0.alpha.

Are you planning to support Rails 5? If so, how could we move forward to achieve that goal?

[chrismear]

Probably the best approach is to help get a new release of Sinatra 1 released that is compatible with Rack 2: sinatra/sinatra#1061

[janraasch]

@chrismear, sounds good. I suppose this is issue is onhold until sinatra/sinatra#1061 is decided then.

This fixed the issue

gem "sinatra", github: 'sinatra/sinatra'
gem "rack-protection", github: 'sinatra/rack-protection'
gem "delayed_job_web"

There is now a release of sinatra (v2.0.0.beta2) which supports Rails 5.

I also just encountered this issue when upgrading an application to Rails 5.

Loading the application fails with the following error:

gems/activesupport-5.0.1/lib/active_support/dependencies.rb:293:in `require':
  cannot load such file -- rack/showexceptions (LoadError)

The current solution is to simply add the line:

gem 'sinatra', '>= 2.0.0.beta2'

to your Gemfile.

For more detail, see this issue in Sinatra.

Wondering what's the updated solution for this. Is there a new version lined up for this gem?

[janraasch]

Since all sinatra issues are solved (see links to issues above), the problem is fixed. We already use this gem with rails v5 in production.

@ejschmitt - Should the readme be updated to say it supports Rails5?

[andyatkinson]

@ACPK Sure. Could you please do that as a new PR and I will merge it in? According to @janraasch they're using it with Rails 5.
