MacksMind / attr_tree.rb
Created March 26, 2013 13:52
Sometimes I've needed a 'deep compare' for ActiveRecord objects. This method returns a Hash containing the objects attributes plus the attributes from the first layer of relationships. After using #except to exclude attributes that should change, I can assert_equal to compare.
class ActiveSupport::TestCase
def attr_tree(obj)
tree = obj.attributes.except("id")
obj.class.reflections.each do |refl_name,refl|
refl_key = refl_name.to_s
case refl.macro
when :belongs_to, :has_one
tree[refl_key] = (o = obj.send(refl_name)) && o.attributes
when :has_many, :has_and_belongs_to_many

Shell script to run multiple test files. This version runs 5 at a time. Change the `-tn 5` to `-t` to run everything at once.
find test/* -type d -maxdepth 2 | xargs -J {} find {} -name '*_test.rb' | xargs -tn 5 bundle exec ruby -I.:test -e "ARGV.each{|f| require f}"

MacksMind / warn_on_escaped_html.rb
Created March 16, 2013 23:51
I'm in the middle of upgrading a Rails app from 2.3 to 3.2. There are many places where html strings are constructed and rendered. This monkey-patch has been a big help in finding all the places I need to use raw or html_safe.
module ActionView
class Template
def render_with_warn_on_escaped_html(*args,&block)
output = render_without_warn_on_escaped_html(*args,&block)
unless Rails.env.production? || args[0].request.instance_variables.include?(:@skip_escaped_html_check)
if output =~ /^.*&lt;.*$/
warn "WARNING: Escaped HTML in #{ Rails.backtrace_cleaner.clean(caller).first }: #{Regexp.last_match}"
args[0].request.instance_variable_set(:@skip_escaped_html_check,true)
end
end
