Hashie warning "You are setting a key that conflicts with a built-in method"

[aoyama-val]

Hashie 3.5.5
Grape 0.19.2

To reproduce:

require "grape"

class MyAPI < Grape::API
  params do
    requires :update, type: Boolean
  end
  get "hoge" do
    "update = #{params[:update]}"
  end
end

run MyAPI

Log:

W, [2017-06-06T14:18:35.531821 #46633]  WARN -- : You are setting a key that conflicts with a built-in method Hashie::Mash#update defined at /Users/val00362/tmp/grapetest/vendor/bundle/ruby/2.3.0/gems/hashie-3.5.5/lib/hashie/mash.rb:209. This can cause unexpected behavior when accessing the key via as a property. You can still access the key via the #[] method.

Hashie::Mash has built-in update method. It's conflicting with my parameter name. Similarly, you would see the warning when you used any of Hashie::Mash's 280+ methods. Is there any workaround about this? Or at least, some caveat to avoid these parameter names should be written in the README.

In 1.0 we're no longer using Hashie::Mash by default, so I think the problem would go away. However this is worth documenting since it's still available. Care to PR?

Thanks for info. To stop using Hashie::Mash sounds like a good idea. However, it would be better to leave fixing the docs to someone else, because I'm not good at writing. English is not my native language...

Try it! We'll correct your English (English is my 3rd language too :))

What are the recommendations to fix this warning message? Tried setting a nil logger but it doesn't seem to fix all cases.

  # config/environments/production.rb
  require "hashie"
  require "hashie/logger"
  Hashie.logger = Logger.new(nil)
