Juggernaut - interesting stuff, needs evaluation.

I got some free time lately, so I sat down trying to figure out how to make pagination of tagged entities. I’m using acts_as_taggable_on_steroids plugin for tagging and will_paginate for pagination of some standard queries.

Pagination plugin allows you to replace ‘find’ method with ‘paginate’ one:

Game.find(:all)
Game.paginate(:all, :page => 1)


Tagging plugin allows ‘tagged_with’ suffix to any ‘find’ method call:

Game.find_tagged_with('tsumego')


It’s easy to find out, that all I needed was:

Game.paginate_tagged_with('tsumego', :page => 1)


This is the power of dynamic languages. Pretty simple and really useful. All those small magic tricks makes writing software in RoR really exiting!

Todays winner is: gemsonrails.

Well, I have to be honest - I’m not the emacs guy and after a few tries of the editor I abandon the idea for emacs to become my Rails/Ruby IDE. The features looked yummy on the screenshots, but practicing Vim Zen is better

After being defeated by emacs, I focused on finding the best solution for old, good Vim. Here is what I found usable for RoR developer:

• rails.vim - easy navigation between rails files, few additional powerful features too, must have!
• snippetsEmu.vim - this is awesome plugin, makes TextMate like snippets possible inside Vim, powerful!
• fuzzyfinder.vim - buffers explorer, works well with :A and :R from rails.vim, bind this as a shortcut for better usability
• surround.vim - something additional found during research, for dealing with every kind of surroundings (like html tags for example), not required, but nice
• SimpleFold.vim - well, if this is not working as described (folds are broken), while bugs free it will join my plugins bundle

Just paste each script name presented above here to find newest versions of them.

My additional snippets I found usable are:


exec "Snippet vn validates_numericality_of :".st."field".et.st.et
exec "Snippet vl validates_length_of :".st."field".et.", :maximum => ".st."max".et.st.et
exec "Snippet vc validates_confirmation_of :".st."field".et.st.et
exec "Snippet vp validates_presence_of :".st."field".et.st.et
exec "Snippet vu validates_uniqueness_of :".st."field".et.st.et


PS. I’m 10 kyu now and won today with 9 kyu with 25 points! I can do it! I will do it!
PS 2. supertab.vim is cool too
PS 3. I’ve got here vim-ruby of course too…

Profiler in Rails. Nice

I finally found one! Enjoy! http://dima-exe.ru/rails-on-emacs

• Buildr - Maven power plus Ruby expressiveness. I think it’s not just yet another build tool. Check for evangelism here and here.
• Rspec - let’s test your code in another way. Approach called ‘Behaviour Driven Development’.
• Facets - Ruby commons. Yummy

While developing my new secret RoR project I’ve found really useful chart library for Ruby. It’s called Gruff and is really worth trying. More details here.
