Nested parameters?

[Joshfindit]

One thing that Rails trips up on quite frequently is nested parameters. Does this gem handle them?

Example 1

works in Rails, but accepts everything in the array

get '/', allows: [:id, :action, :relationships[ ] ] do
  erb :index
end

Example 2

does not work in rails, but is the ideal

get '/', allows: [:id, :action, :relationships[ allows: [:id, name]] ] do
  erb :index
end

Not currently, no. Though I don't know why we couldn't implement something like that.

Are you looking to nest :allows and :needs within each other? That might get complicated... but being able to just allow certain parts of nested parameters should be doable. I'm thinking something like this:

get '/', allows: [:id, :action, :relationships[:id, name]] do
  erb :index
end

Which would allow only the :id and :name params inside of the :relationships param.

Not looking to nest :allows and :needs within each other, no; it feels like madness lies that way at anything past 2 levels.

That syntax makes sense. How do you feel about people abusing the system with the following or worse?

get '/', allows: [:id, :action, :relationships[:id, :name, :parents[:id, :name, :grandparents[:id, :name, :sisters[:id, :name]]]]] do
  erb :index
end

I agree, that seems like chaos.

Seems pretty wild, but there's no reason it shouldn't work. We'd just have to implement it so we can recurse through nested arrays.
