Annotate ActiveRecord models as a gem

Annotate (aka AnnotateModels)¶ ↑

Add a comment summarizing the current schema to the top or bottom of each of your…

* ActiveRecord models
* Fixture files
* Tests and Specs
* Object Daddy exemplars
* Machinist blueprints
* Fabrication fabricators

The schema comment looks like this:

# == Schema Info
#
# Table name: line_items
#
#  id                  :integer(11)    not null, primary key
#  quantity            :integer(11)    not null
#  product_id          :integer(11)    not null
#  unit_price          :float
#  order_id            :integer(11)
#

 class LineItem < ActiveRecord::Base
   belongs_to :product
  . . .

It also annotates geometrical columns, geom type and srid, when using SpatialAdapter or PostgisAdapter:

# == Schema Info
#
# Table name: trips
#
#  local           :geometry        point, 4326
#  path            :geometry        line_string, 4326

Also, if you pass the -r option, it’ll annotate routes.rb with the output of “rake routes”.

INSTALL¶ ↑

Into Gemfile from Github:

gem 'annotate', :git => 'git://github.com/ctran/annotate_models.git'

Into environment gems From Rubygems.org:

sudo gem install annotate

Into environment gems from Github checkout:

git clone git://github.com/ctran/annotate_models.git annotate
cd annotate
rake build
sudo gem install pkg/annotate-*.gem

USAGE¶ ↑

(If you used the Gemfile install, prefix the below commands with ‘bundle exec`.)

To annotate all your models, tests, fixtures, etc.:

cd /path/to/app
annotate

To annotate your models and tests:

annotate --exclude fixtures

To annotate just your models:

annotate --exclude tests,fixtures

To annotate routes.rb:

annotate -r

To automatically annotate after running ‘rake db:migrate’:

[*needs more clarity*] unpack the gem into vendor/plugins, or maybe vendor/gems, or maybe just require tasks/migrate.rake.

If you install annotate_models as a plugin, it will automatically adjust your rake db:migrate tasks so that they update the annotations in your model files for you once the migration is completed. To get the same behavior from a gem, add the following to your Rakefile:

require 'annotate/tasks'

To customize the behavior of annotate when it is running as a Rake task, use the following (in your Rakefile or wherever):

ENV['position_in_class']   = "before"
ENV['position_in_fixture'] = "before"
ENV['show_indexes']        = "false"
ENV['include_version']     = "false"
ENV['exclude_tests']       = "false"
ENV['exclude_fixtures']    = "false"
ENV['skip_on_db_migrate']  = "false"

OPTIONS¶ ↑

Usage: annotate [options] [model_file]*
    -d, --delete                     Remove annotations from all model files
    -p, --position [before|after]    Place the annotations at the top (before) or the bottom (after) of the model file
    -r, --routes                     Annotate routes.rb with the output of 'rake routes'
    -v, --version                    Show the current version of this gem
    -m, --show-migration             Include the migration version number in the annotation
    -i, --show-indexes               List the table's database indexes in the annotation
    -s, --simple-indexes             Concat the column's related indexes in the annotation
        --model-dir dir              Annotate model files stored in dir rather than app/models
    -R, --require path               Additional files to require before loading models
    -e, --exclude [tests,fixtures]   Do not annotate fixtures, test files, or both

WARNING¶ ↑

Note that this code will blow away the initial/final comment block in your models if it looks like it was previously added by annotate models, so you don’t want to add additional text to an automatically created comment block.

* * Back up your model files before using... * *
