I'm working on a Rails 4.2 app and have just added app/services/fetch_artists.rb
to the structure. Inside this file, I have defined a class FetchArtists; end
.
When trying to run rails r 'FetchArtists'
it gives me a NameError: uninitialized constant FetchArtists
.
I've tried looking at ActiveSupport::Dependencies.autoload_paths
and indeed, app/services
is not there:
/.../app/assets
/.../app/controllers
/.../app/helpers
/.../app/jobs
/.../app/mailers
/.../app/models
/.../app/controllers/concerns
/.../app/models/concerns
/.../spec/mailers/previews
My question is, why isn't this folder automatically loaded, and what should I do for it to be?
EDIT
Very strange, after repeatedly running the above command with rails runner
, the new folder appears on the autoload paths. I have no idea why this happened with such a lag.
Someone suggested this may deal with spring
. I would like to hear more on this, since it can possibly help many others in this situation too.
I encountered the same problem and it seems to be a caching issue with Spring, a process which handles preloading your app. It's used for the web server as well as the console and Rake tasks.
Stopping Spring with bin/spring stop
will force Spring to load your app fresh. Now running rails console
and inspecting ActiveSupport::Dependencies.autoload_paths
will successfully show app/services
.
