Oj: Oj.dump ignores :symbol_keys option

[trevorrowe]

When dumping a hash, the :symbol_keys option does not seem to have any effect when passed as false, example:

require 'oj'

# notice the ':' prefix of they key
puts Oj.dump({:abc => 123}, :symbol_keys => false)
#=> {":abc":123}

# same result
puts Oj.dump({:abc => 123}, :symbol_keys => true)
#=> {":abc":123}

Is this expected behavior?

That is expected behavior. The symbolize_keys option only applies to loading.

What is your recommendation if I have a hash with symbol keys, that I want dumped to JSON without the colon prefixes? I can recursively stringify-keys on the hash, but that does not seem like it would be very performant. Thoughts?

There are 4 modes OJ can use for dumping. This is to help people find the right level of conversion from Ruby to JSON. The :compat mode will convert symbols to strings. Try this

Oj.dump({a:1,b:2}, mode: :compat)
