These are things I occasionally need to use in Rails and waste ages re-finding each time.

Stop ActiveRecord Logging to the Console when I run ./script/server

config.active_record.logger = Logger.new("/dev/null")

Problems:

  • Migrations fail

Call Helper Methods in a Controller

When it’s overkill to use a partial, sometimes you need to format text to respond to an AJAX call. The trick is to use @template:

The Helper

module FoosHelper
  def bazify(foo)
    { :qux => "%.2f" % foo.attrib }
  end
end

The Controller

class FoosController < ApplicationController

  def bar
    foo = Foo.find(params[:id])
    render :text => @template.bazify(bar).to_json
  end

end
