Rails.cache does not properly cache "false", it returns nil instead.
This is because the value is checked with an
if value
...
else
value = nil # => sets false values to nil
end
I changed it to:
if defined?(value)
Example:
Rails.cache.fetch('foo') { false }
=> false # uncached value
Rails.cache.fetch('foo') { false }
=> nil # from cache
