I am able to duplicate this.

This problem does not occur if you use hydra-head instead of hydra in the gemfile.

jeremyf commented 11 years ago

I'm wondering if this is a matter of including explicit requires for the underlying hydra related gems?

jcoyne commented 11 years ago

Is this because having hydra in your gemfile never requires the hydra-head gem?

jcoyne commented 11 years ago

@jeremyf I don't think it'll be that easy, since https://github.com/projecthydra/hydra-head/blob/master/hydra-core/lib/hydra-core.rb#L1 does require 'hydra' which it expects to be this file: https://github.com/projecthydra/hydra-head/blob/master/hydra-core/lib/hydra.rb

But you've defined that module already in the hydra gem itself.

flyingzumwalt commented 11 years ago

Related: before getting this error, I got "Blacklight not defined" when my gentile just listed hydra without listing bl.

jeremyf commented 11 years ago

I created a new project, with Gemfile:

gem 'hydra', path: '../hydra'
gem 'blacklight'

And the only error I got was one related to app/models/user.rb being expected. (Ruby 1.9.3)

cbeer commented 11 years ago

This is exactly what SimonLamb reported in IRC last week. Rails (Ruby? Bundler?) doesn't auto-require second-order dependencies.

jeremyf commented 11 years ago

I'm switching to Ruby 2.0.0 to see if I can duplicate the problem, because if I can't, then I really don't stand a chance of fixing this.

jeremyf commented 11 years ago

If I use :path as a gem option, I can't duplicate. If I use the rc2 I can. Obviously :path is not a good solution.

jeremyf commented 11 years ago

I just minted 6.0.0.rc3, you shouldn't need the explicit blacklight declaration.

I successfully ran rails generate hydra:head -f from command line. To tweak get it to work locally, I used my hydra repo, tweaked the code then ran rake build && rake install, and switched over to my dummy hydra-head and ran bundle with a Gemfile of

source 'https://rubygems.org'

gem 'hydra', '6.0.0.rc3'
gem 'sqlite3'

followed by rails generate hydra:head -f.

jcoyne commented 11 years ago

When I upgraded to rc3, the generator does pass. However, when you start the server rails s I get this error:

/Users/justin/workspace/minnebar/app/models/user.rb:3:in `<class:User>': uninitialized constant Hydra::User (NameError)
    from /Users/justin/workspace/minnebar/app/models/user.rb:1:in `<top (required)>'
jeremyf commented 11 years ago

Try hydra 6.0.0.rc6
