Hi, Assume I'm doing an API in Rails 4 with StrongParameters, and I got a model like Pricing, with many Prices. I want my API to support in one endpoint nested attributes for the Prices of a Pricing. The consumer of the API doesn't care that I am using Rails, so he sends me the nested attributes of the Prices as :prices, but Rails is expecting :prices_attributes And I am just wondering if it could be possible to bring extra options on Strong Parameters, to rename keys like: params.permit(:prices, :description, ...) params.rename(:prices, :prices_attributes) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
