How should ActiveRecord behave with merging conditions from various sources? See rails/rails#9813 for background.

  • clobber: conflicting condition values are replaced with the rightmost value
  • append: conflicting condition values are chained into an AND query

Direct find

                Problem with different level of precision when adding ActiveSupport::Duration than Fixnum seconds. It looks like Rails 4.0 has a fix for this. The bug (illustrated here with plain ruby) depends on the system environment for the precision error to show up.
              
          

        

      

        

  

    
    


        



  


  

        

          
          require 'active_support/time'
        

        

          
          require 'active_support/version'
        

        

          
          

        

        

          
          t0 = Time.now # => 2013-05-26 01:14:51 +0000
        

        

          
          t1 = t0 + 86400
        

        

          
          t2 = t0 + 1.day
        

        

          
          

        

        

          
          puts "Ruby %s / ActiveSupport %s" % [RUBY_VERSION, ActiveSupport::VERSION::STRING]
        

        

          
          puts "Time + Fixnum nsec:       %s" % t1.nsec  # => 11111111

                IDEA: To add layout options for Rails
              
          

        

      

        

  

      

    
Override ActionController layout class method to take a view_options hash, whether or not the actual layout template is being changed:


layout "foo", view_options: {sidebar: 'special'}
layout view_options: {sidebar: 'special'}



Define a LayoutOptions module in the controller class and give it to the view helpers. It would define methods:
