Unable to autoload constant User

[stabenfeldt]

Hi,

This happens when I try to start rails console. Any idea what might be wrong?

I'm running using grape (0.7.0) and grape-entity (0.4.3)

activesupport-4.1.1/lib/active_support/dependencies.rb:481:in
 `load_missing_constant': Unable to autoload constant User, expected app/api/v1/user.rb to define it (LoadError)
    from /.rvm/gems/ruby-2.1.2@A/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:180:in `const_missing'

app/api/api.rb

class API < Grape::API
  prefix 'api'
  mount V1::User
end

app/api/v1/user.rb

module V1
  class User < Grape::API
    before { restrict_access! }
    version 'v1', using: :path, vendor: 'martin', cascade: false

    helpers do
      include ApiHelpers
    end

    format :json
    desc 'Returns pong.'
    get :users do
      users = User.all
      present :users, users, with: V1::Entities::Users
    end
  end
end

application.rb

require File.expand_path('../boot', __FILE__)

# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"

# Require the gems listed in Gemfile, including any gems

Bundler.require(*Rails.groups)

module AngularCRUD
  class Application < Rails::Application
    config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
    config.assets.initialize_on_precompile = true
    config.assets.paths << Rails.root.join('vendor', 'assets', 'components')

    config.autoload_paths += %W(#{config.root}/lib)

    config.action_dispatch.default_headers = {
          'X-Frame-Options' => 'ALLOWALL'
    }


    # Auto-load API and its subdirectories
    config.paths.add 'app/api', glob: '**/*.rb'
    config.autoload_paths += Dir["#{Rails.root}/app/api/*"]



  end
end

Don't see anything obvious, but I have a working project in https://github.com/dblock/grape-on-rails with Rails 4.1. Compare with its structure.

Thanks, I'll have a look at that! :)

Post here what you find. Feel free to upload the project if you can't figure it out.

[stabenfeldt]

Thanks, I'll do that! :-)

I decided to keep it simple for now and decided to just use "routes API,
V1" for now.
I'll definitely take an other look at Grape when I need to extend my API.
Thanks for helping out!

Cheers,
Martin
