Since i switched to Rails 3 i figured out that you dont need to escape html contents (using h method in Rails 2), its been done automatically. So, for now if you have any plugins or methods that produce raw html you have to use method “html_safe” to unescape it.

Before:

<%= your_helper_method %>

Now:

# your helper method
def your_helper_method
    # .... content generation
    return content.html_safe
end

In in view:

<%= your_helper_method %>

Authlogic is a good authentication library for Rails, supports a lot of different methods. But its not fully compatible with Rails 3 which is solvable. This solution works for latest gem version (2.1.6):

Basically, default setup is the same, nothing specific;

class UserSession < Authlogic::Session::Base ; end

And you’ll probably get error message like this:

undefined method `to_key’ for <UserSession: no credentials provided>

In this case all you have to do is to define additional method in your UserSession model:

class UserSession < Authlogic::Session::Base
  def to_key
    new_record? ? nil : [ self.send(self.class.primary_key) ]
  end
end

And everything should work just fine.

Need to troubleshoot email output? No problem. Just need to configure your development environment with the following lines:

# RAILS_ROOT/config/environments/development.rb
config.action_mailer.delivery_method = :sendmail 
config.action_mailer.sendmail_settings = {:location => "/usr/bin/fake-sendmail.sh"}
config.action_mailer.default_url_options = { :host => "YOUR HOST" }

And here is the fake-sendmail utility i wrote: (save as “/usr/bin/fake-sendmail.sh”)

#!/usr/bin/ruby
 
dir = "/tmp/fake-sendmail"
headers = ''; $stdin.each_line { |l| headers << l ; break if l.strip.length == 0 }
body = '' ; $stdin.each_line { |l| body << l }
format = body.match(/html/i) ? "html" : "txt"
filename = Time.now.to_i
 
Dir.mkdir(dir) unless File.exists?(dir)
File.open("#{dir}/#{filename}_headers.txt", "w") { |f| f.write(headers) }
File.open("#{dir}/#{filename}.#{format}", "w") { |f| f.write(body) }

As the result you’ll see 2 files created for each outgoing email. One has all email headers and another one has the body.

Also, it works for Sinatra and Merb. Woot!
