rspec navigation using rails.vim

mitjok — Wed, 31 Oct 2007 13:37:01 +0000

Tim Pope hinted about adding custom Rcommands to supports navigation in rspec files with rails.vim plugin Something like :Rspecmodel, :Rspeccontroller, :Rspecview, :Rspechelper. Just add the following code in your .vimrc:

" RSpec navigation commands
autocmd User Rails Rcommand specmodel spec/models -glob=**/*
\-suffix=_spec.rb -default=model()
autocmd User Rails Rcommand spechelper spec/helpers -glob=**/*
\-suffix=_helper_spec.rb -default=controller()
autocmd User Rails Rcommand speccontroller spec/controllers -glob=**/*
\-suffix=_controller_spec.rb -default=controller()
autocmd User Rails Rcommand specview spec/views -glob=**/*
\-suffix=_view_spec.rb

You may customize :Rspecview command to match ‘html.erb’ suffix. And of course, :RSmodel, :RScontroller, etc. opens specs in split window.

Ruby method access levels: protected and private

mitjok — Thu, 27 Sep 2007 15:58:43 +0000

Good example which illustrate the difference between protected and private methods in Ruby:

• Protected methods can be invoked only by objects of the defining class and its subclasses. Access is kept within the family.
• Private methods cannot be called with an explicit receiver—the receiver is always self. This means that private methods can be called only in the context of the current object; you can’t invoke another object’s private methods. (c) PickAxe.

1. Feed your database with data using scaffolding forms.
2. Extract them with rake task into your .yml file.
3. To make them convert correctly to UTF-8 use Ya2YAML instead to_yaml in above rake task.
