Working fine in development but not in production with Unicorn

[Jon Fernández]

Its working fine in development environment. But in production I get this error:

INFO -- : Refreshing Gem list
NoMethodError: undefined method `impersonates' for ApplicationCable::Connection:Class

In development I'm using puma and in production unicorn, is it possible that this doesn't work with unicorn?

[Andrew Kane]

I'd be very surprised if that was the case. Have you tried Unicorn in development?

[Jon Fernández]

I forgot to detail that the problem is only in ActionCable, looks like it doesn't load the Gem or something...

I tried to test it in development with Unicorn but my application needs Puma-dev with subdomains.

Cleaning up issues. If you get to the bottom of it, let me know.

Hi,

@ankane I've got the same issue in staging or production environments. You can reproduce it in local by adding config.eager_load = true in development.rb

Seems like the impersonates method is called before your ActiveSupport.on_load(:action_cable) callback ?

[Andrew Kane]

Thanks @verlinden, can you give master a shot?

[Sébastien Charrier]

@ankane I got the exact same issue in staging and production (for the same eager_load config) and using the master version of pretenders fixed it. Thanks!

[Steve Verlinden]

@ankane I confirm it's working fine now. Thanks 👍

[Andrew Kane]

Thank you both, just released a new version.
