If this is set to <tt>true</tt> (the default) then <tt>respond_to</tt> and <tt>Request#format</tt> will take the Accept header into account. If it is set to false then the request format will be determined solely by examining <tt>params[:format]</tt>.

+ * Update the USAGE file to add helpful documentation for your generator
+
+=== Testing generators ===
+
+Many rails plugin authors do not test their generators, however testing generators is quite simple.  A typical generator test does the following:
+
+ * Creates a new fake rails root directory that will serve as destination
+ * Runs the generator
+ * Asserts that the correct files were generated
+ * Removes the fake rails root
+
+This section will describe how to create a simple generator that adds a file.  For the generator in this section, the test could look something like this:
+
+*vendor/plugins/yaffle/test/definition_generator_test.rb*
+
+[source, ruby]
+------------------------------------------------------------------
+require File.dirname(__FILE__) + '/test_helper.rb'
+require 'rails_generator'
+require 'rails_generator/scripts/generate'
+
+class DefinitionGeneratorTest < Test::Unit::TestCase
+
+  def fake_rails_root
+    File.join(File.dirname(__FILE__), 'rails_root')
+  end
+  
+  def file_list
+    Dir.glob(File.join(fake_rails_root, "*"))
+  end
+
+  def setup
+    FileUtils.mkdir_p(fake_rails_root)
+    @original_files = file_list
+  end
+
+  def teardown
+    FileUtils.rm_r(fake_rails_root)
+  end
+  
+  def test_generates_correct_file_name
+    Rails::Generator::Scripts::Generate.new.run(["yaffle_definition"], :destination => fake_rails_root)
+    new_file = (file_list - @original_files).first
+    assert_equal "definition.txt", File.basename(new_file)
+  end
+  
+end
+------------------------------------------------------------------
+
+You can run 'rake' from the plugin directory to see this fail.  Unless you are doing more advanced generator commands it typically suffices to just test the Generate script, and trust that rails will handle the Destroy and Update commands for you.
+
+To make it pass, create the generator:
+
+*vendor/plugins/yaffle/generators/yaffle_definition/yaffle_definition_generator.rb*
+
+[source, ruby]
+------------------------------------------------------------------
+class YaffleDefinitionGenerator < Rails::Generator::Base
+  def manifest
+    record do |m|
+      m.file "definition.txt", "definition.txt"
+    end
+  end
+end
+------------------------------------------------------------------
+
+=== The USAGE file ===
+
+If you plan to distribute your plugin, developers will expect at least a minimum of documentation.  You can add simple documentation to the generator by updating the USAGE file.
+
+Rails ships with several built-in generators.  You can see all of the generators available to you by typing the following at the command line:
+
+------------------------------------------------------------------
+./script/generate
+------------------------------------------------------------------
+
+You should see something like this:
+
+------------------------------------------------------------------
+Installed Generators
+  Plugins (vendor/plugins): yaffle_definition
+  Builtin: controller, integration_test, mailer, migration, model, observer, plugin, resource, scaffold, session_migration
+------------------------------------------------------------------
+
+When you run `script/generate yaffle_definition -h` you should see the contents of your 'vendor/plugins/yaffle/generators/yaffle_definition/USAGE'.  
+
+For this plugin, update the USAGE file could look like this:
+
+------------------------------------------------------------------
+Description:
+    Adds a file with the definition of a Yaffle to the app's main directory

-== Create a generator ==
-
-Many plugins ship with generators.  When you created the plugin above, you specified the --with-generator option, so you already have the generator stubs in 'vendor/plugins/yaffle/generators/yaffle'.
-
-Building generators is a complex topic unto itself and this section will cover one small aspect of generators:  creating a generator that adds a time-stamped migration.
-
-To create a generator you must:
-
- * Add your instructions to the 'manifest' method of the generator
- * Add any necessary template files to the templates directory
- * Test the generator manually by running various combinations of `script/generate` and `script/destroy`
- * Update the USAGE file to add helpful documentation for your generator
-
-=== Testing generators ===
-
-Many rails plugin authors do not test their generators, however testing generators is quite simple.  A typical generator test does the following:
-
- * Creates a new fake rails root directory that will serve as destination
- * Runs the generator forward and backward, making whatever assertions are necessary
- * Removes the fake rails root
-
-For the generator in this section, the test could look something like this:
-
-*vendor/plugins/yaffle/test/yaffle_generator_test.rb*
-
-[source, ruby]
-------------------------------------------------------------------
-require File.dirname(__FILE__) + '/test_helper.rb'
-require 'rails_generator'
-require 'rails_generator/scripts/generate'
-require 'rails_generator/scripts/destroy'
-

-
-You can run 'rake' from the plugin directory to see this fail.  Unless you are doing more advanced generator commands it typically suffices to just test the Generate script, and trust that rails will handle the Destroy and Update commands for you.
-
-=== Adding to the manifest ===
-
-This example will demonstrate how to use one of the built-in generator methods named 'migration_template' to create a migration file.  To start, update your generator file to look like this:
-
-*vendor/plugins/yaffle/generators/yaffle/yaffle_generator.rb*
-
-[source, ruby]
-------------------------------------------------------------------
-class YaffleGenerator < Rails::Generator::NamedBase
-  def manifest
-    record do |m|
-      m.migration_template 'migration:migration.rb', "db/migrate", {:assigns => yaffle_local_assigns,
-        :migration_file_name => "add_yaffle_fields_to_#{custom_file_name}"
-      }
-    end
-  end
-
-  private
-    def custom_file_name
-      custom_name = class_name.underscore.downcase
-      custom_name = custom_name.pluralize if ActiveRecord::Base.pluralize_table_names
-    end
-
-    def yaffle_local_assigns
-      returning(assigns = {}) do
-        assigns[:migration_action] = "add"
-        assigns[:class_name] = "add_yaffle_fields_to_#{custom_file_name}"
-        assigns[:table_name] = custom_file_name
-        assigns[:attributes] = [Rails::Generator::GeneratedAttribute.new("last_squawk", "string")]
-      end
-    end
-end
-------------------------------------------------------------------
-
-The generator creates a new file in 'db/migrate' with a timestamp and an 'add_column' statement.  It reuses the built in rails `migration_template` method, and reuses the built-in rails migration template.
-
-It's courteous to check to see if table names are being pluralized whenever you create a generator that needs to be aware of table names.  This way people using your generator won't have to manually change the generated files if they've turned pluralization off.
-
-=== Manually test the generator ===
-
-To run the generator, type the following at the command line:
-
-------------------------------------------------------------------
-./script/generate yaffle bird
-------------------------------------------------------------------
-
-and you will see a new file:
-
-*db/migrate/20080529225649_add_yaffle_fields_to_birds.rb*
-
-[source, ruby]
-------------------------------------------------------------------
-class AddYaffleFieldsToBirds < ActiveRecord::Migration
-  def self.up
-    add_column :birds, :last_squawk, :string
-  end
-
-  def self.down
-    remove_column :birds, :last_squawk
-  end
-end
-------------------------------------------------------------------
-
-

-
-------------------------------------------------------------------

+== Migrations ==
+
+If your plugin requires changes to the app's database you will likely want to somehow add migrations.  Rails does not include any built-in support for calling migrations from plugins, but you can still make it easy for developers to call migrations from plugins.
+
+If you have a very simple needs, like creating a table that will always have the same name and columns, then you can use a more simple solution, like creating a custom rake task or method.  If your migration needs user input to supply table names or other options, you probably want to opt for generating a migration.
+
+Let's say you have the following migration in your plugin:
+
+*vendor/plugins/yaffle/lib/db/migrate/20081116181115_create_birdhouses.rb:*
+
+[source, ruby]
+----------------------------------------------
+class CreateBirdhouses < ActiveRecord::Migration
+  def self.up
+    create_table :birdhouses, :force => true do |t|
+      t.string :name
+      t.timestamps
+    end
+  end
+
+  def self.down
+    drop_table :birdhouses
+  end
+end
+----------------------------------------------
+
+Here are a few possibilities for how to allow developers to use your plugin migrations:
+
+=== Create a custom rake task ===
+
+*vendor/plugins/yaffle/lib/db/migrate/20081116181115_create_birdhouses.rb:*
+
+[source, ruby]
+----------------------------------------------
+class CreateBirdhouses < ActiveRecord::Migration
+  def self.up
+    create_table :birdhouses, :force => true do |t|
+      t.string :name
+      t.timestamps
+    end
+  end
+
+  def self.down
+    drop_table :birdhouses
+  end
+end
+----------------------------------------------
+
+
+*vendor/plugins/yaffle/tasks/yaffle.rake:*
+
+[source, ruby]
+----------------------------------------------
+namespace :db do
+  namespace :migrate do
+    desc "Migrate the database through scripts in vendor/plugins/yaffle/lib/db/migrate and update db/schema.rb by invoking db:schema:dump. Target specific version with VERSION=x. Turn off output with VERBOSE=false."
+    task :yaffle => :environment do
+      ActiveRecord::Migration.verbose = ENV["VERBOSE"] ? ENV["VERBOSE"] == "true" : true
+      ActiveRecord::Migrator.migrate("vendor/plugins/yaffle/lib/db/migrate/", ENV["VERSION"] ? ENV["VERSION"].to_i : nil)
+      Rake::Task["db:schema:dump"].invoke if ActiveRecord::Base.schema_format == :ruby
+    end
+  end
+end
+----------------------------------------------
+
+=== Call plugin migrations from regular migrations ===
+
+*vendor/plugins/yaffle/lib/yaffle.rb:*
+
+[source, ruby]
+----------------------------------------------
+Dir.glob(File.join(File.dirname(__FILE__), "db", "migrate", "*")).each do |file|
+  require file
+end
+----------------------------------------------
+
+*db/migrate/20081116181115_create_birdhouses.rb:*
+
+[source, ruby]
+----------------------------------------------
+class CreateBirdhouses < ActiveRecord::Migration
+  def self.up
+    Yaffle::CreateBirdhouses.up
+  end
+
+  def self.down
+    Yaffle::CreateBirdhouses.down
+  end
+end
+----------------------------------------------
+
+NOTE: several plugin frameworks such as Desert and Engines provide more advanced plugin functionality.
+
+== Generating migrations ==
+
+Generating migrations has several advantages over other methods.  Namely, you can allow other developers to more easily customize the migration.  The flow looks like this:
+
+ * call your script/generate script and pass in whatever options they need
+ * examine the generated migration, adding/removing columns or other options as necessary
+
+This example will demonstrate how to use one of the built-in generator methods named 'migration_template' to create a migration file.  Extending the rails migration generator requires a somewhat intimate knowledge of the migration generator internals, so it's best to write a test first:
+
+*vendor/plugins/yaffle/test/yaffle_migration_generator_test.rb*
+
+[source, ruby]
+------------------------------------------------------------------
+require File.dirname(__FILE__) + '/test_helper.rb'
+require 'rails_generator'
+require 'rails_generator/scripts/generate'
+require 'rails_generator/scripts/destroy'
+
+class MigrationGeneratorTest < Test::Unit::TestCase
+
+  def fake_rails_root
+    File.join(File.dirname(__FILE__), 'rails_root')
+  end
+  
+  def file_list
+    Dir.glob(File.join(fake_rails_root, "db", "migrate", "*"))
+  end
+
+  def setup
+    FileUtils.mkdir_p(fake_rails_root)
+    @original_files = file_list
+  end
+
+  def teardown
+    FileUtils.rm_r(fake_rails_root)
+  end
+  
+  def test_generates_correct_file_name
+    Rails::Generator::Scripts::Generate.new.run(["yaffle", "some_name_nobody_is_likely_to_ever_use_in_a_real_migration"], :destination => fake_rails_root)
+    new_file = (file_list - @original_files).first
+    assert_match /add_yaffle_fields_to_some_name_nobody_is_likely_to_ever_use_in_a_real_migrations/, new_file
+    assert_match /add_column :some_name_nobody_is_likely_to_ever_use_in_a_real_migrations do |t|/, File.read(new_file)
+  end
+
+  def test_pluralizes_properly
+    ActiveRecord::Base.pluralize_table_names = false
+    Rails::Generator::Scripts::Generate.new.run(["yaffle", "some_name_nobody_is_likely_to_ever_use_in_a_real_migration"], :destination => fake_rails_root)
+    new_file = (file_list - @original_files).first
+    assert_match /add_yaffle_fields_to_some_name_nobody_is_likely_to_ever_use_in_a_real_migration/, new_file
+    assert_match /add_column :some_name_nobody_is_likely_to_ever_use_in_a_real_migration do |t|/, File.read(new_file)
+  end
+  
+end
+------------------------------------------------------------------
+
+NOTE: the migration generator checks to see if a migation already exists, and it's hard-coded to check the 'db/migrate' directory.  As a result, if your test tries to generate a migration that already exists in the app, it will fail.  The easy workaround is to make sure that the name you generate in your test is very unlikely to actually appear in the app.
+
+After running the test with 'rake' you can make it pass with:
+
+*vendor/plugins/yaffle/generators/yaffle/yaffle_generator.rb*
+
+[source, ruby]
+------------------------------------------------------------------
+class YaffleGenerator < Rails::Generator::NamedBase
+  def manifest
+    record do |m|
+      m.migration_template 'migration:migration.rb', "db/migrate", {:assigns => yaffle_local_assigns,
+        :migration_file_name => "add_yaffle_fields_to_#{custom_file_name}"
+      }
+    end
+  end
+
+  private
+    def custom_file_name
+      custom_name = class_name.underscore.downcase
+      custom_name = custom_name.pluralize if ActiveRecord::Base.pluralize_table_names
+    end
+
+    def yaffle_local_assigns
+      returning(assigns = {}) do
+        assigns[:migration_action] = "add"
+        assigns[:class_name] = "add_yaffle_fields_to_#{custom_file_name}"
+        assigns[:table_name] = custom_file_name
+        assigns[:attributes] = [Rails::Generator::GeneratedAttribute.new("last_squawk", "string")]
+      end
+    end
+end
+------------------------------------------------------------------
+
+The generator creates a new file in 'db/migrate' with a timestamp and an 'add_column' statement.  It reuses the built in rails `migration_template` method, and reuses the built-in rails migration template.
+
+It's courteous to check to see if table names are being pluralized whenever you create a generator that needs to be aware of table names.  This way people using your generator won't have to manually change the generated files if they've turned pluralization off.

+=== Generate the plugin skeleton ===
+
+Rails ships with a plugin generator which creates a basic plugin skeleton. Pass the plugin name, either 'CamelCased' or 'under_scored', as an argument. Pass `\--with-generator` to add an example generator also.
+
+This creates a plugin in 'vendor/plugins' including an 'init.rb' and 'README' as well as standard 'lib', 'task', and 'test' directories.
+
+Examples:
+----------------------------------------------
+./script/generate plugin yaffle
+./script/generate plugin yaffle --with-generator
+----------------------------------------------
+
+To get more detailed help on the plugin generator, type `./script/generate plugin`.
+
+Later on this guide will describe how to work with generators, so go ahead and generate your plugin with the `\--with-generator` option now:
+
+----------------------------------------------
+./script/generate plugin yaffle --with-generator
+----------------------------------------------
+
+You should see the following output:
+

-Rails ships with a plugin generator which creates a basic plugin skeleton. Pass the plugin name, either 'CamelCased' or 'under_scored', as an argument. Pass `\--with-generator` to add an example generator also.
-
-This creates a plugin in 'vendor/plugins' including an 'init.rb' and 'README' as well as standard 'lib', 'task', and 'test' directories.
-
-Examples:
-----------------------------------------------
-./script/generate plugin yaffle
-./script/generate plugin yaffle --with-generator
-----------------------------------------------
-
-To get more detailed help on the plugin generator, type `./script/generate plugin`.
-
-Later on this guide will describe how to work with generators, so go ahead and generate your plugin with the `\--with-generator` option now:
-
-----------------------------------------------
-./script/generate plugin yaffle --with-generator
-----------------------------------------------
-
-You should see the following output:
-
-----------------------------------------------
-create  vendor/plugins/yaffle/lib
-create  vendor/plugins/yaffle/tasks
-create  vendor/plugins/yaffle/test
-create  vendor/plugins/yaffle/README
-create  vendor/plugins/yaffle/MIT-LICENSE
-create  vendor/plugins/yaffle/Rakefile
-create  vendor/plugins/yaffle/init.rb
-create  vendor/plugins/yaffle/install.rb
-create  vendor/plugins/yaffle/uninstall.rb
-create  vendor/plugins/yaffle/lib/yaffle.rb
-create  vendor/plugins/yaffle/tasks/yaffle_tasks.rake
-create  vendor/plugins/yaffle/test/core_ext_test.rb
-create  vendor/plugins/yaffle/generators
-create  vendor/plugins/yaffle/generators/yaffle
-create  vendor/plugins/yaffle/generators/yaffle/templates
-create  vendor/plugins/yaffle/generators/yaffle/yaffle_generator.rb
-create  vendor/plugins/yaffle/generators/yaffle/USAGE
-----------------------------------------------
-
-To begin just change one thing - move 'init.rb' to 'rails/init.rb'.
-
-=== Setup the plugin for testing ===
+== Tests ==
 
 If your plugin interacts with a database, you'll need to setup a database connection.  In this guide you will learn how to test your plugin against multiple different database adapters using Active Record.  This guide will not cover how to use fixtures in plugin tests.
