• Sunspot_Rails Rake Aborted When Running Reindex

  - by Walter Chen

  I'm getting the following output after running rake sunspot:reindex. I'm a novice at Rails. I want to add sunspot_rails to my project to add search functionality (with the hope of deploying the project with Heroku). I'm using Rails 3. I followed the instructions here: https://github.com/outoftime/sunspot/blob/master/sunspot_rails/README.rdoc. My various other attempts to diagnose the problem included: installing sunspot in addition to sunspot_rails. I ended up with sunspot_rails v. 1.2.0 and 1.2.1 so I uninstalled 1.2.1 because I have sunspot_rails 1.2.0. installed the nokogiri gem which I understand is a dependency for sunspot_rails. installed libxml2 separately following the instructions here to install nokogiri: http://www.engineyard.com/blog/2010/getting-started-with-nokogiri/ ** Invoke sunspot:reindex (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute sunspot:reindex rake aborted! undefined local variable or method counter' for [removed pound]<Class:0x10359aef8> /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:1008:inmethod_missing' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:235:in solr_index' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/relation/batches.rb:71:infind_in_batches' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:in __send__' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:infind_in_batches' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:234:in solr_index' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:184:insolr_reindex' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:57 /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56:in each' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56 /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:incall' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:597:ininvoke_with_call_chain' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/monitor.rb:242:in synchronize' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:ininvoke_with_call_chain' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:583:in invoke' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2051:ininvoke_task' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:instandard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2001:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in standard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/bin/rake:31 /usr/bin/rake:19:in `load' /usr/bin/rake:19 This is what I have in class I'd like to search: searchable do text :fname text :mname text :lname, :default_boost => 2 end Any help would be greatly appreciated!

• In Ruby on Rails, why will story.votes return an empty Array object, but story.votes.create will act

  - by Jian Lin

  In Ruby on Rails, say a Story object can "has_many" Vote objects (a story is voted "hot" by many users). So when we do a s = Story.find(:first) s is a Story object, and say s.votes returns [] and s.votes.class returns Array So clearly, s.votes is an empty Array object. At this time, when s.votes.create is called, it actually invokes a method of the Vote class? How come an Array class object can invoke a Vote class method?

• Is there a Rails authentication library which separates users from login methods?

  - by Gareth

  In my mental model of authentication, a user should be distinct from the way they log in. So for example, a User could have an associated EmailLogin (with an email/password), or they could have many (or none). Similarly they could have 0..* associated OpenIDLogin credentials. Are there any existing authentication libraries for Rails which use this method? Alternatively, is this a really terrible idea?

• Is Prince the best way to PDF in Ruby on Rails?

  - by Angela

  After several Google searches, it appears that the way to create PDF's in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the what's and how's.

• Is there any way to disable Erubis from printing "** Erubis 2.6.5" when starting the Rails environme

  - by Nathan

  I have several frequent Cron jobs that are run via Rake and the output of those jobs are e-mailed (via a MAILTO). Due to the fact that these tasks load the Rails environment (which includes Erubis) they always prints out "** Erubis 2.6.5" on startup. This means that an e-mail is always generated since Cron receives output. Is there any way to configure Erubis to cease printing this startup message to the console?

• Grails benchmarks compared to other web MVC platform (Rails, Django, ASP MVC)?

  - by fabien7474

  I have been searching the web for recent benchmarks measuring Grails overall performance compared to its competitors (Rails, Django, ASP.NET MVC...), but I didn't find anything more recent than a 3 years-old article with obsolete grails version (0.5). See here and here. So, starting from grails 1.2, are there any more recent grails benchmarks you are aware of ? Or do you have your own performance tests for grails (compared to others if possible) ?
