== 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
- Thoughtbot's factory_girl factories, i.e. the (spec|test)/factories/<model>_factory.rb files
- routes.rb file

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 rubygems.org:

    gem 'annotate', ">=2.5.0.pre3"

Into Gemfile from Github:

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

Into environment gems From rubygems.org:

    gem install annotate

Into environment gems from Github checkout:

    git clone git://github.com/ctran/annotate_models.git annotate_models
    cd annotate_models
    rake build
    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 remove annotations:

  annotate -d

To automatically annotate after running 'rake db:migrate', ensure you've added
annotate_models to your Rails project's Gemfile, and run this:

  rails g annotate_models:install

This will produce a .rake file that will ensure annotation happens after
migration (but only in development mode), and provide configuration options
you can use to tailor the output.

If you want to always skip annotations on a particular model, add this string
anywhere in the file:

  # -*- SkipSchemaAnnotations

== 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
            --ignore-model-subdirects    Ignore subdirectories of the models directory
            --sort                       Sort columns alphabetically, rather than in creation order
        -R, --require path               Additional files to require before loading models
        -e, --exclude [tests,fixtures]   Do not annotate fixtures, test files, or both
        -f [bare|rdoc|markdown],         Render Schema Infomation as plain/RDoc/Markdown
            --format
            --force                      Force new annotations even if there are no changes.
            --trace                      If unable to annotate a file, print the full stack trace, not just the exception message.


== SORTING

By default, columns will be sorted in database order (i.e. the order in which migrations were run).

If you prefer to sort alphabetically so that the results of
annotation are consistent regardless of what order migrations are executed in, use  --sort.

== 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 MODELS BEFORE USING THIS TOOL!
