params and error

when using curl -i -X POST -H "Content-Type:application/json" http://127.0.0.1:3000/cf_templates/1/cf_deployments -d '{"env":"cit_certification"}'

I see (in the logs):

Parameters: {"env"=>"cit_certification", "cf_template_id"=>"1", "cf_deployment"=>{"env"=>"cit_certification"}}

and the error:

Completed 500 Internal Server Error in 31ms (ActiveRecord: 9.2ms)
ActiveModel::UnknownAttributeError (unknown attribute 'cf_deployment' for CfDeployment.):
