rakismet¶ ↑

You have to provide your API key, your site url, mapping hash which maps fields from your comment form to variables required by Akismet and predicate which indicates if a request should be checked by Akismet.

require ‘rubygems’ require ‘sinatra’

require File.join(File.dirname(__FILE__), ‘..’, ‘lib’, ‘rakismet.rb’)

get ‘/’ do

%{<html><head><title>Rakismet</title></head><body>
<form action="/posts" method="post">
  <label for="comment_author">author</author>
  <input type="text" name="author" id="comment_author" />
  <br />

  <label for="comment_email">email</label>
  <input type="text" name="email" id="comment_email" />
  <br />
  <label for="comment_url">url</author>
  <input type="text" name="url" id="comment_url" />
  <br />
  <label for="comment_content">content</author>
  <input type="text" name="content" id="content" />
  <br />

  <input type="submit" value="submit" />
</form>
</body></html>}

end

post ‘/posts’ do

if request.spam?
  "spammer!!"
else
  "<html><head><title>Rakismet</title></head><body>OHAI!</body></html>"
end

end

"email" => :comment_author_email,
"url" => :comment_author_url,
"content" => :comment_content }

predicate = lambda do |path, method, form_data|

path =~ /posts/ && method == "POST"
