vagrant: rsync config

rsync set for vagrant

As of Vagrant 1.5, you can use RSync shared folders which will provide a dramatic increase in disk I/O between the host and guest. To use RSync for shared folders, simply add the following to your

Vagrantfile:

config.vm.synced_folder ".", "/vagrant", type: "rsync"

Using Associations

Quick quiz, hotshot: suppose users have a “status”: active, inactive, pensive, etc. What’s the right association?

class User < ActiveRecord::Base
  belongs_to :status  # this?
  has_one :status     # or this?
end

rails: run code in a view using ERB

Run code in a view using ERB:

  • <% ... %>: Run the code, but don’t print anything. Used for if/then/else/end and array.each loops. You can comment out sections of HTML using <% if false %> Hi there <% end %>. You get a free blank line, since you probably have a newline after the closing %>.

  • <%- ... %>: Run the code, and don’t print the trailing newline. Use this when generating XML or JSON when breaking up .rhtml code blocks for your readability, but don’t want newlines in the output.

  • <%= ... %>: Run the code and print the return value, for example: <%= @foo %> (You did remember the @ sign for controller variables passed to the view, right?). Don’t put if statements inside the <%=, you’ll get an error.

  • <%= h ... %>: Print the code and html escape the output: > becomes >. h() is actually a Ruby function, but called without parens, as Rubyists are apt to do.
