Question

I have this method form a Rails 2.3.4 app:

def self.find_all_colored(query, options={})
  finder_options = {:conditions => "color = #{query}"}.merge(options)
  Car.find(:all, finder_options)
end

With which I can do:

Car.find_all_colored("red", :limit => 5)

But I am having a really bad time trying to get that to work in Rails 3.1.1, by now I can make it work but without the .merge(options), if I add that part:

def self.find_all_colored(query, options={})
  Car.where("color = #{query}").merge(options)
end

I get this error:

undefined method `default_scoped?' for {:limit=>5}:Hash

I’ve googled and searched in stackoverflow.com but no luck…thanks!

Try the following:

def self.find_all_colored(query, options={})
  self.all({:conditions => {:color => query}}.merge(options))
end
