Answer 1

I don' Penso che il problema sia legato a heroku. Ho avuto un errore in uno dei miei modelli in cui avevo qualcosa come belongs_to :type1, :type2, per il quale avrei dovuto averli in 2 righe separate - come belongs_to :type1 belongs_to :type2 (Strano che il rake non ha generato alcun errore nel mio locale).

Dopo aver risolto questo problema, ho riscontrato anche un altro problema. Heroku stava gettando questo errore -

Fetching gem metadata from https://rubygems.org/.. 
Could not find safe_yaml-0.9.4 in any of the sources 

non ho avuto safe_yaml-0.9.4 nel mio Gemfile, ma ha scoperto che era inclusa nel mio Gemfile.lock. Ho cambiato safe_yaml-0.9.4 in safe_yaml-0.9.3 e ho premuto su heroku. Tutto è tornato alla normalità ora.

Ci scusiamo per il titolo ingannevole. Ma se qualcun altro si imbatte nell'errore arity con heroku proprio come ho fatto io, questo potrebbe dare la soluzione.

Answer 2

Vai al tuo production.rb file in config/environments

Cercare la linea config.eager_load e regolarlo a config.eager_load = true
