Update via JSON

[danielpclark]

How do you update an existing model from JSON? I can't seem to figure out the use of from_json and update with this.

Currently, Topaz doesn't have def to_json and def from_json. (Just have def self.to_json and def self.from_json via JSON.mapping)
But it is a really necessary feature to be implemented...

What I thought is somehing like this.

class JsonSample < Topaz::Model
    columns(name: String)
end

JsonSample.create(name: "OK")

json_sample = JsonSample.find(1) # The name of this is "OK"
json_sample.update(%({"name": "NG"}))

puts JsonSample.find(1).name # => "NG"

Yes, I like it. I've been trying to think what kind of Object it would need to be JSON::Any or maybe JSON::Puller for the update method… since having a String type doesn't indicate to the update method that it's in JSON format.

Also I've been trying to think of how it would work (how to implement it). I'd have to experiment a bit before I can come up with an implementation.
