Terminal Admin

README.md

TerminalAdmin

Slightly inspired by the interactive_editor gem, this allows you to edit mongoid documents as yaml in vim. Once the file is written, the changes are applied to that object. If you tack on the bang, then the changes are automatically persisted to the database.

example:

require 'mongoid'

Mongoid.configure do |config|
  config.master = Mongo::Connection.new.db("terminal_admin")
end

class Product
  include Mongoid::Document
  field :name, :type => String
  field :price, :type => Integer
end

require 'terminal_admin'

product = Product.new

product.edit

terminal_admin.rb

module Mongoid::Document
  require 'tempfile'

  def edit
    tmp_file = new_temp_file
    open_for_editing(tmp_file)
    update_from_file(tmp_file)
  end

  def edit!
    edit
    save
  end

  private

  def editable_fields
    fields.keys - ["_id", "_type"]
  end

  def editable_attributes
    attrs = {}
    editable_fields.each { |k| attrs[k] = attributes[k] }
    attrs
  end

  def new_temp_file
    tmp_file = Tempfile.new([self._id, '.yml'])
    tmp_file.open
    tmp_file.write(editable_attributes.to_yaml)
    tmp_file.close
    tmp_file
  end

  def open_for_editing(tmp_file)
    system "vim #{tmp_file.path}"
  end

  def update_from_file(tmp_file)
    attrs = YAML.load(tmp_file.open.read)
    self.attributes = attrs
  end
end

Nice idea. It would be great to use ENV['EDITOR'] instead of hardcoding vim.
