Help with --help option for react_on_rails

[justin808]

See below for an example of what rails generate model --help does. Missing for react_on_rails:

• Defaults for options (default is for the flag to be off, so default of -b means that skip-bootstrap is off. Default for -R is that redux is off.
• Detailed description. At least specify the URL of more docs.

Usage:
  rails generate react_on_rails:install [options]

Options:
  -R, [--redux], [--no-redux]                          # Install Redux gems and Redux version of Hello World Example
  -S, [--server-rendering], [--no-server-rendering]    # Add necessary files and configurations for server-side rendering
  -j, [--skip-js-linters], [--no-skip-js-linters]      # Skip installing JavaScript linting files
  -L, [--ruby-linters], [--no-ruby-linters]            # Install ruby linting files, tasks, and configs
  -H, [--heroku-deployment], [--no-heroku-deployment]  # Install files necessary for deploying to Heroku
  -b, [--skip-bootstrap], [--no-skip-bootstrap]        # Skip integrating Bootstrap and don't initialize files and regarding configs

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

This is an example of what we should strive for:

rails generate model --help                                                                                                                                                              ✭ [12:26:22]
Usage:
  rails generate model NAME [field[:type][:index] field[:type][:index]] [options]

Options:
      [--skip-namespace], [--no-skip-namespace]  # Skip namespace (affects only isolated applications)
      [--force-plural], [--no-force-plural]      # Forces the use of the given model name
  -o, --orm=NAME                                 # Orm to be invoked
                                                 # Default: active_record

ActiveRecord options:
      [--migration], [--no-migration]    # Indicates when to generate migration
                                         # Default: true
      [--timestamps], [--no-timestamps]  # Indicates when to generate timestamps
                                         # Default: true
      [--parent=PARENT]                  # The parent class for the generated model
      [--indexes], [--no-indexes]        # Add indexes for references and belongs_to columns
                                         # Default: true
  -t, [--test-framework=NAME]            # Test framework to be invoked
                                         # Default: test_unit

TestUnit options:
      [--fixture], [--no-fixture]   # Indicates when to generate fixture
                                    # Default: true
  -r, [--fixture-replacement=NAME]  # Fixture replacement to be invoked

Runtime options:
  -f, [--force]                    # Overwrite files that already exist
  -p, [--pretend], [--no-pretend]  # Run but do not make any changes
  -q, [--quiet], [--no-quiet]      # Suppress status output
  -s, [--skip], [--no-skip]        # Skip files that already exist

Description:
    Stubs out a new model. Pass the model name, either CamelCased or
    under_scored, and an optional list of attribute pairs as arguments.

    Attribute pairs are field:type arguments specifying the
    model's attributes. Timestamps are added by default, so you don't have to
    specify them by hand as 'created_at:datetime updated_at:datetime'.

    As a special case, specifying 'password:digest' will generate a
    password_digest field of string type, and configure your generated model and
    tests for use with ActiveModel has_secure_password (assuming the default ORM
    and test framework are being used).

    You don't have to think up every attribute up front, but it helps to
    sketch out a few so you can start working with the model immediately.

    This generator invokes your configured ORM and test framework, which
    defaults to ActiveRecord and TestUnit.

    Finally, if --parent option is given, it's used as superclass of the
    created model. This allows you create Single Table Inheritance models.

    If you pass a namespaced model name (e.g. admin/account or Admin::Account)
    then the generator will create a module with a table_name_prefix method
    to prefix the model's table name with the module name (e.g. admin_accounts)

Available field types:

    Just after the field name you can specify a type like text or boolean.
    It will generate the column with the associated SQL type. For instance:

        `rails generate model post title:string body:text`

    will generate a title column with a varchar type and a body column with a text
    type. If no type is specified the string type will be used by default.
    You can use the following types:

        integer
        primary_key
        decimal
        float
        boolean
        binary
        string
        text
        date
        time
        datetime

    You can also consider `references` as a kind of type. For instance, if you run:

        `rails generate model photo title:string album:references`

    It will generate an `album_id` column. You should generate these kinds of fields when
    you will use a `belongs_to` association, for instance. `references` also supports
    polymorphism, you can enable polymorphism like this:

        `rails generate model product supplier:references{polymorphic}`

    For integer, string, text and binary fields, an integer in curly braces will
    be set as the limit:

        `rails generate model user pseudo:string{30}`

    For decimal, two integers separated by a comma in curly braces will be used
    for precision and scale:

        `rails generate model product 'price:decimal{10,2}'`

    You can add a `:uniq` or `:index` suffix for unique or standard indexes
    respectively:

        `rails generate model user pseudo:string:uniq`
        `rails generate model user pseudo:string:index`

    You can combine any single curly brace option with the index options:

        `rails generate model user username:string{30}:uniq`
        `rails generate model product supplier:references{polymorphic}:index`

    If you require a `password_digest` string column for use with
    has_secure_password, you should specify `password:digest`:

        `rails generate model user password:digest`

Examples:
    `rails generate model account`

        For ActiveRecord and TestUnit it creates:

            Model:      app/models/account.rb
            Test:       test/models/account_test.rb
            Fixtures:   test/fixtures/accounts.yml
            Migration:  db/migrate/XXX_create_accounts.rb

    `rails generate model post title:string body:text published:boolean`

        Creates a Post model with a string title, text body, and published flag.

    `rails generate model admin/account`

        For ActiveRecord and TestUnit it creates:

            Module:     app/models/admin.rb
            Model:      app/models/admin/account.rb
            Test:       test/models/admin/account_test.rb
            Fixtures:   test/fixtures/admin/accounts.yml
            Migration:  db/migrate/XXX_create_admin_accounts.rb

@justin808 below description is a bit confusing:

• Defaults for options (default is for the flag to be off, so default of -b means that skip-bootstrap is off. Default for -R is that redux is off.

should it be ?:
