Rails 5.0.0.beta1 - Generating an URL from non sanitized request parameters is insecure

Question

We are upgrading from Rails 4.2.5 to 5.0.0.beta1

When testing we expected to see index views rendered with paginated links as before. But we now get an ArgumentError error page, for example:

ArgumentError in Transactions#index 
/app/views/kaminari/_paginator.html.erb where line #10 raised:


<%= paginator.render do -%>

Generating an URL from non sanitized request parameters is insecure!

An issue has been raised with kaminari

On further investigation here is the new Rails 5.0.0.beta1 code that now throws the error:

Adding this to config/application.rb 'fixes' it, but not a great idea:

config.action_controller.permit_all_parameters = true

Instead adding this does not fix the issue, not sure why:

config.action_controller.always_permitted_parameters =  [:current_page, :page, :total_pages, :per_page, :remote, :paginator]

Answer 1

This appears to be fixed in the github master branch, so for now in your gem file specify:

gem 'kaminari', :git => "git://github.com/amatsuda/kaminari.git", :branch => 'master'
