How to define Rails' has_many attributes?

[lazywei]

Hi there,

In Rails, I can use

has_many :apps
accepts_nested_attributes_for :apps

and then pass parameters to controller

{ ..., "apps_attributes": [ {"name": "hello", ...}, ... ] }

How can I define params for such use case?

Must I define like this?

param :apps_attributes

And, how to define array? The document for Array Validator seems not for such case.

Thanks.

I found that #229 and #230 seems to be created for such use case.

I tried:

param :store do
  ...
  param :apps_attributes, Array do
    param :description
  end
end

and in document:

store[apps_attributes]
Value: Must be an Array of nested elements

store[apps_attributes][description] 
Value: Must be String

store[apps_attributes][description] seems a little confusing. If I saw some docs like this, I may misunderstand it, and pass parameter likes ... {"apps_attributes": {"description: ... }} ..., which is definitely wrong.

Yeah, We had first just a nested hash support, and added the arrays there later, but keeping the same way how we display the stuff. I'm not sure which would be the best solution to this …
