If parameter has symbol, it will be error

[lion-man44]

I just update this gem v0.18.0 and got error like this.

     Failure/Error: Integer(string || '')

     TypeError:
       can't convert Symbol into Integer

I found problem here.
This code can't get Symbol.

  def number_or_nil(string)
    Integer(string || '')
  rescue ArgumentError
    nil
  end

if you use json in router or something, probably it includes Symbol in value this code.

    parameters.each_pair do |key, value|
      next unless number_or_nil(value)

This is my parameters.

{:format=>:json, :controller=>"*", :action=>"create", :id=>"897"}

So, could anyone help to submit PR like this?

      next unless number_or_nil(value.to_s)

I tried to create PR but I couldn't understand how to write test code in this gem.

Could you make a repro, something like this:

Sorry, it will take times in my environment if you are okay just try this one in your router.

Rails.application.routes.draw do
  defaults format: :json do
  end
end

And then, I found workaround thankfully if I rewrite :json to 'json' as a String.
It worked

Rails.application.routes.draw do
  defaults format: 'json' do
  end
end

Thanks for the workaround @lion-man44.

A bit more info for @exoego, while running the gem locally with a bit of debug code:

    76:   def number_or_nil(string)
    77:     if string.is_a?(String)
    78:       Integer(string || '')
    79:     else
 => 80:       binding.irb
    81:     end
    82:   rescue ArgumentError
    83:     nil
    84:   end
    85: end

irb(#<Object:0x000000013c835990>):001> string
=> :json
