Hobo app crashing on Heroku with - NameError (uninitialized constant Dryml::TemplateEnvironment):

[kiwi lloyd]

Hi
I have built an app with hobo and it works fine on my local PC however crashes when I try to run it on Heroku.  It was working OK on Heroku but something has changed and I don't know what!  The start of the error trace is:

2013-10-25T19:12:25.177964+00:00 heroku[web.1]: State changed from starting to up

My environment is:
hobo 2.0.1
rails 3.2.12
ruby 1.9.3p327

Any ideas?

thanks
Lloyd

Hi Lloyd,

This is a strange error, like if Heroku couldn't find that class. Can
you try to go back in git history to a previous commit, to see if it's
something related to a change you've made?

If that's not the problem, please tell us and I'll try to create a test
app to reproduce it in Heroku.

Warm regards,
Ignacio

Hi Ignacio
Thanks very much for the fast reply!

It will be something I have done that has caused the error, however there have been many changes since I last pushed to Heroku so I'm not sure what is causing it.
It is fine in development but not on Heroku, so there is something different between the environments. I am starting to look at the initializers to see if there are problems there, as presumably the class is not getting created.
The app is fairly complicated - integration with Shopify and Omniauth, several custom DRYML taglib files, custom initializers, JavaScript libs and a bunch of other gems.

I have another app and that works fine on Heroku.

So any suggestions on where to look would be really appreciated. Is there any info on how Hobo gets initialized when starting - eg what starts all the DRYML file compiles?

Best regards
Lloyd

Hi Lloyd,

I would start with config/initializers/dryml_taglibs.rb. By default it
precompiles stuff only in production mode. You can try disabling that
line (see

Some progress...

The problem does not seem to be related to Hobo. It is because modules are not being autoloaded by rails on Heroku. I noticed that one of my modules was not being loaded.  When I did a "require 'my module'" in application.rb the module got loaded OK.  All the autoload paths are correct and I changed the threadsafe option, however I am still not able to get the hobo modules autoloaded.

The diagnosis continues...

Thanks for posting your progress...
