ngannotate-rails not working in development mode

Question

I'm using ngannotate-rails to help get angular code to work in a compressed format. This is in a Rails 3.2 + Angular 1.5.x app.

I've added the following to my Gemfile and ran bundle

group :assets do
  gem 'sprockets-derailleur', '~> 1.0.0'          # Speed up precompiles with multi-core compile
  gem 'turbo-sprockets-rails3', '~> 0.3.14'       # Compile only changed assets
  gem 'sass-rails', ' ~> 3.2'                   # Main CSS extension in use
  gem 'less', '~> 2.6.0'                          # Less required for ui-utils plugin for AngularJS
  gem 'therubyracer', '~> 0.12.1'                 # v8 library required for less
  gem 'coffee-rails'                              # Language which compiles into JS
  gem 'uglifier'                      # JS parser, minifier, compressor or beautifier toolkit

  gem 'ngannotate-rails', '~> 1.2'                # AngularJS minifier
end

Then in config/environments/development.rb I've added the following

  if ENV['NG_FORCE'] == 'true'
    config.assets.compress = true
    config.assets.compile = true
    config.assets.digest = true
    config.assets.debug = false

    # Don't fallback to assets pipeline if a precompiled asset is missed
    config.assets.precompile += %w(*.css *.js *.woff *.eot *.svg *.ttf) # The fix for font-awesome

  else
    # Do not compress assets
    config.assets.compress = false

    # Expands the lines which load the assets
    config.assets.debug = true
  end

I then do the following commands but ng-annotate is not annotating

NG_FORCE=true RAILS_ENV=development bundle exec rake assets:clean assets:precompile:primary
NG_FORCE=true rails s

I check the compiled output in public/assets/.../ and I get this at the top;

(function(){var e;e=function(e,n,t,i,o,c,r,a,u,d,s,l,v,f,g,h,m,p,b,k,y,I,T,E,q,w,A){var D,P,F,x,j;

It's minified but not annotated with the strings so AngularJS throws this error;

UPDATE

InvoicesController

InvoicesController = ($scope, $http, $location, $state, $stateParams, $uibModal, $timeout, flash, Invoice, Division, Costing, Job, JobService, Common, ShortcutService, InvoiceService, TimesheetService, DisbursementService, DebtorService, SearchService, LineItemService, DateService, $filter, $mdDialog, $mdMedia, Restangular, hotkeys) ->

<Snip: Too long>
  switch $state.current.name
    # Index

    when "invoices"
      $scope.query = SearchService.getFilter('invoices')
      page = SearchService.getPage('invoices')

      if ($scope.query)
        # Filter already exists
        $scope.filterForm = true
        getInvoices(angular.extend({}, $scope.query, {page: page, limit: 10, search: $scope.query}))
      else if page > 0
        $scope.query = { order: '-invoice_no', limit: 10,  page: page }
        $scope.onPaginate(page, 10)
      else
        $scope.resetFilter()

angular
  .module('paisApp')
  .controller('InvoicesController', InvoicesController)

Although it might have been cut off in your snippet above, I don't see where you would have provided the "ngInject" directive in you code.

I would expect your controller code to look like

MyController = ($scope, ...) ->
  "ngInject"
  # etc

It's the "ngInject" that ng-annotate looks for as the hook in points when transpiling the code.
