0.18 Uncaught Error: Unknown template object: function

[attenzione]

Somewhere here:

function template(templateSpec, env) {
  /* istanbul ignore next */
  if (!env) {
    throw new Exception("No environment passed to template");
  }
  if (!templateSpec || !templateSpec.main) {
    throw new Exception('Unknown template object: ' + typeof templateSpec);
  }
  ...

I got the same error too

Getting similar error if updating from 17.1

[AlexRiedler]

Thanks for the headsup guys, updated to handlebars 0.18 without having a rails installation handy and on the go. I will try to look into it in about 3 hours from now.

@dbkbali @PikachuEXE @attenzione is this due to rails caching ? I can not longer replicate after cleaning my rails tmp folder. (Handlebars output from compile is different format; and its not backwards compatible).

[attenzione]

I will test it later, thanks for advise

Clearing the cache in development and recompiling the assets on deploy does solve it

[attenzione]

ok guys, clearing assets cache will resolve this problem, but i would recommend to add post comment when installing new gem version this issue could be closed, but can be opened some time for other users

[AlexRiedler]

I am gonna think about it before closing; maybe there is some way I can notify that on a gem version change it should bump the cache version or something similar (cause this is an annoying issue for developing the plugin I have as well).

[attenzione]

@AlexRiedler, you can add post message to gemspec, for example "after updating gem you should run rake assets:clobber to recompile all javascript" https://github.com/jnunemaker/httparty/blob/e38baab559bb078ee421676b752d9877e5828b48/httparty.gemspec#L18

[tjgrathwell]

Just asking the user to run rake assets:clobber isn't sufficient on Heroku, which seems to cache the old assets as well. It would be nice if there was a way for the gem to break the template cache somehow.

Uncaught Error: Unknown template object: function It doesn't go away after removing-precompiling assets, removing tmp and rake:assets:clobber

[AlexRiedler]

Does anyone know any better options? I will investigate some more when I have time.

[simeonwillbanks]

@tjgrathwell How'd you successfully deploy to Heroku? Thanks!

[simeonwillbanks]

https://github.com/heroku/heroku-buildpack-ruby/issues/123#issuecomment-59845522 helped.

1. Ensure running latest sprockets-rails
2. $ heroku plugins:install https://github.com/heroku/heroku-repo.git
3. $ heroku repo:purge_cache -a appname
4. $ git push heroku master

Still seeing this error on 0.18, clearing tmp didn't work.

[Breefield]

Nvm, clear tmp + touch restart.txt and there we go.

[deivinsontejeda]

I had the same issue with ember-rails once I deleted cache, everything works as expected. So I suggest you remove the cache on rm -rf tmp/*

[AlexRiedler]

okay so I found a way to fix this, and will be implemented in next release! (automatically cleans cache on update of the gem).

[Breefield]

Wonderful, thanks Alex!
