Rails javascript asset missing after precompile

Question

the Rails Guides says:

If there are missing precompiled files in production you will get an Sprockets::Helpers::RailsHelper::AssetPaths::AssetNotPre

Answer 1

Actually two things needed to do:

config.assets.precompile += %w( *.js *.css )

as described here, and

config.serve_static_assets = true

for local production testing when using

rail s

of course using

rake assets:precompile

however in my case - without config.assets.precompile this would have no effect since the manifest didn't contain any reference to my javascript file.

HTH.
