bundle exec rake assets:precompile
</plain>
Asset templates in general have access to application objects. You may prevent application
initialization in precompilation setting +config.assets.initialize_on_precompile+ to false.
For faster asset precompiles, you can partially load your application by setting
+config.assets.initialize_on_precompile+ to false, though in that case templates
cannot see application objects or methods. *Heroku requires this to be false.*
WARNING: Application objects may still be in scope in asset templates in develoment mode.
If +config.assets.initialize_on_precompile+ is set to false it is your responsability not
to use them at all.
WARNING: If you set +config.assets.initialize_on_precompile+ to false, be sure to
test +rake assets:precompile+ locally before deploying. It may expose bugs where
your assets reference application objects or methods, since those are still
in scope in development mode regardless of the value of this flag.
