AnnotateRb

forked from the Annotate aka AnnotateModels gem

A Ruby Gem that adds annotations to your Rails models and route files.

---

Adds comments summarizing the model schema or routes in your:

• ActiveRecord models
• Fixture files
• Tests and Specs
• FactoryBot factories
• routes.rb file (for Rails projects)

The schema comment looks like this:

# == Schema Information
#
# Table name: tasks
#
#  id         :integer          not null, primary key
#  content    :string
#  count      :integer
#  status     :boolean
#  created_at :datetime         not null
#  updated_at :datetime         not null
#
class Task < ApplicationRecord
  ...

---

Installation

$ gem install annotaterb

Or install it into your Rails project through the Gemfile:

group :development do
  ...

  gem "annotaterb"
  
  ...

Automatically annotate models

For Rails projects, model files can get automatically annotated after migration tasks. To do this, run the following command:

$ bin/rails g annotate_rb:install

This will copy a rake task into your Rails project's lib/tasks directory that will hook into the Rails project rake tasks, automatically running AnnotateRb after database migration rake tasks.

To skip the automatic annotation that happens after a db task, pass the environment variable ANNOTATERB_SKIP_ON_DB_TASKS=1 before your command.

$ ANNOTATERB_SKIP_ON_DB_TASKS=1 bin/rails db:migrate

Added Rails generators

The following Rails generator commands get added.

$ bin/rails generator --help

...

AnnotateRb:
  annotate_rb:config
  annotate_rb:hook
  annotate_rb:install
  annotate_rb:update_config
...

bin/rails g annotate_rb:config

• Generates a new configuration file, .annotaterb.yml, using defaults from the gem.

bin/rails g annotate_rb:hook

• Installs the Rake file to automatically annotate Rails models on a database task (e.g. AnnotateRb will automatically run after running bin/rails db:migrate).

bin/rails g annotate_rb:install

• Runs the config and hook generator commands

bin/rails g annotate_rb:update_config

• Appends to .annotaterb.yml any configuration key-value pairs that are used by the Gem. This is useful when there's a drift between the config file values and the gem defaults (i.e. when new features get added).

Migrating from the annotate gem

Configuration

Storing default options

Previously in the Annotate you could pass options through the CLI or store them as environment variables. Annotaterb removes dependency on the environment variables and instead can read values from a .annotaterb.yml file stored in the Rails project root.

# .annotaterb.yml

position: after

Annotaterb reads first from the configuration file, if it exists, then merges it with any options passed into the CLI.

For further details visit the section in the migration guide.

How to skip annotating a particular model

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

# -*- SkipSchemaAnnotations

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.
