ActiveRecord Json Should fail no? - ruby-on-rails

Question

I am using the ActiveRecord Json Validator Gem and I have the following object thats trying to be saved to the model, which should fail, but instead isnt:
[1] pry(#<Api::Internal::V1::UsersController>)> backup
=> #<UserBackup:0x24eddeed
id: nil,
location_name: "test",
user_params: {"user"=>{"user_name"=>"GeorgeLucas", "email"=>"asdsadasdas", "auth_token"=>"jesus"}, "controller"=>"api/internal/v1/users", "action"=>"create"}>
[2] pry(#<Api::Internal::V1::UsersController>)> backup.save!
=> true
As you can see theres a unsaved UserBackup model object in [1] and in [2] is saves, the json in [1] is missing somethig that is set to required: first_name.
The model looks like such:
class UserBackup < ActiveRecord::Base
PROFILE_JSON_SCHEMA = Rails.root.join('config', 'schemas', 'user.json_schema').to_s
validates :location_name, :presence => true
validates :user_params, :presence => true, json: {schema: PROFILE_JSON_SCHEMA}
end
The Json Schema Looks like:
{
"type": "object",
"$schema": "http://json-schema.org/draft-03/schema",
"properties": {
"user": {
"first_name": {
"type": "string",
"required": true
},
"last_name": {
"type": "string",
"required": false
},
"user_name": {
"type": "string",
"required": true
},
"email": {
"type": "string",
"required": true,
"format": "email"
},
"auth_token": {
"type": "string",
"required": true
}
}
}
}
According to my schema, first_name must be a string and it is a required field.
In my json being saved, its missing entirely. Which means that the model should not save the object to the database.
Update One:
Looking at the model object the user_params doesn't look like a json object at all, it looks like a hash of hashes. So with that in mind, here is the controller:
module Api
module Internal
module V1
class UsersController < BaseController
before_action :restrict_api_access
def create
params_json = params.to_json
backup = UserBackup.new(location_name: from_site, user_params: params_json)
binding.pry
if backup.save
return render json: {}, status: 200
else
return render json: {}, status: 422
end
end
end
end
end
end
params_json is indeed a json object:
[3] pry(#<Api::Internal::V1::UsersController>)> params_json
=> "{\"user\":{\"user_name\":\"GeorgeLucas\",\"email\":\"asdsadasdas\",\"auth_token\":\"jesus\"},\"controller\":\"api/internal/v1/users\",\"action\":\"create\"}"
So I am unsure at this point, what exactly is going on.
