Rails JSON conversion error

Question

I'm getting a strange error when trying to convert my object to json for an API connection. The following details my experience.

If I call

JSON.generate(self)

the output is

{"validation_context":null,"errors":{},"params":{"number":"123","name":"test"}}

I only need the params in my json object and when I call

JSON.generate(self.params) # or the next line
JSON.generate(@params) #params has been set on the object as an accessor

I get

undefined method `merge' for #<JSON::Ext::Generator::State:0x1043f1a38>

For some reason params is not considered a Hash. It serializes ok when I'm getting the parent object but fails otherwise. How can I serialize just the params?

Turns out I found a relatively simple solution.

Rather than

JSON.generate(object_to_serialize)

Using

object_to_serialize.to_json

Will work as intended.
