• Installing a rails plugin from a Git repository

  - by Daniel Beardsley

  I've been trying to install Shoulda script/plugin install git://github.com/thoughtbot/shoulda.git but all I get is: removing: C:/Documents and Settings/Danny/My Documents/Projects/Ruby On Rails/_ProjectName_/vendor/plugins/shoulda/.git > And the vender/plugins directory is empty. I have Rails 2.1.1 installed as a gem and have verified that 2.1.1 is loaded (using a puts inserted into config/boot.rb). Any ideas about what's going on? (this is on a windows box)

• Rake uninitialized constant RDoc::RDoc

  - by Joshua

  When ever I run make I get this 'uninitialized constant RDoc::RDoc' error rake -T (in Main) rake aborted! uninitialized constant RDoc::RDoc C:/Ruby186/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2383:in `raw_load_rakefile' (See full trace by running task with --trace) --edit Running --trace it seems the only non rails code is from rdoc_rails.

• Rails - asynchronous tasks, forked processes, best practices

  - by LisaPatton

  I'm using a Observer on my classes. When one of the records is created/updated I need to notfify another service (via a URL call). What is the best way to do this to avoid slowing down my class? Would using a gem liked delayed_job be overkill? In my Observer's after_update() / after_create() I just want to launch a thread that calls the URL...

• Set compression level when generating a ZIP file using RubyZip

  - by Vincent Robert

  Hi, I have a Ruby program that zips a directory tree of XML files using the rubyzip gem. My problem is that the file is starting to be heavy and I would like to increase the compression level, since compression time is not an issue. I could not find in the rubyzip documentation a way to specify the compression level for the created ZIP file. Anyone know how to change this setting?

• MongoDB initialization error in Rails

  - by rube_noob

  I have an initialization script to set up my MongoDB connection in the config/initialization directory. It is my understanding that these initializers run after all of the plugins are initialized. The problem I am having is that when a particular plugin I am using is initialized, it tries to access the mongodb before I have set it up. I get this error: uninitialized class variable @@database_name in MongoMapper My question is: Where can I initialize Mongodb that will run after the mongodb gem has been loaded and before any of the plugins are initialized?

• rails declarative authorization, permit all actions for controller?

  - by SooDesuNe

  using the delcarative_authorization gem for rails, is there a shortcut to allow a role access to all controller actions? privileges do # default privilege hierarchies to facilitate RESTful Rails apps privilege :manage, :includes => [:create, :read, :update, :delete] end isn't sufficient, because I have more controlling methods than just CRUD in my controllers. Something like: role :foo do has_permission_on :bar, :to =>[:all] end would be perfect, but I'm not finding it in the docs.

• Ruby on Rails solution for scrubbing data of WYSIWYG editor user input

  - by Jimmy

  Hey everyone, I am working on a simple blogging type ruby on rails application and I have everything working through tinyMCE for a nice WYSIWYG editor so the user can add some simple things like images/youtube videos and lists. What I am looking for is a nice solution for blacklisting certain elements to be filtered out of the data when it is displayed. So is there a solution for this available as a gem or available to download anywhere? Thanks!

• Ruby / rubyzip alternative capable of handling rar/tar/zip/7z?

  - by Nick Gorbikoff

  I was wondering if anyone knows of rubyzip alternatives for Ruby, that can handle various formats in particular zip / rar / 7z? I know of libarchive, but it's not complete for my purposes ( it's a good gem thou). (To clarify, libarchive - won't work for me - cause I need to be able to run in on Windows. ( Yeah I know sucks to be me)) Right now I end up running system commands to the os, but I'd like something OS independent, and capable of handling those formats - reading and writing. Thank you

• Ruby on rails authlogic config (get rid of capitalization check)

  - by bandhunt

  The authlogic rails gem is doing a LOWER in the sql query. SELECT * FROM `users` WHERE (LOWER(`users`.email) = '[email protected]') LIMIT 1 I want to get rid of the LOWER part since it seems to be slowing down the query by quite a bit. I'd prefer to just lower the case in the code since this query seems to be expensive. I'm not sure where to change this behavior in authlogic. Thanks!

• RAILS: bundler does not install the package. (bundle install package)

  - by Joern Akkermann

  I started using bundler (which is to my eyes a pure desaster). Now I want to add the Googlebase-gem to my app. So I entered "bundler install googlebase" in the root of my app. Bundler in fact installs several gems, but not Googlebase. What have I done wrong?

• What quality, parser-generator options exist for ruby?

  - by cartoonfox

  What open source (preferably gem-based) parser-generator options do I have in Ruby? I've used (flex&bison)|(lex&yacc) from C in the past, and I'm comfortable with BNF-style specifications. I've heard of treetop, but it looks a bit alien and verbose compared to yacc... Purpose: I want to convert my text markup language to a BNF and generate the parsing code. I think it's a better strategy than my first-order solution: http://github.com/dafydd/semantictext/blob/master/lib/semantictext/rich_text_parser.rb
