Ruby on rails 如何覆盖Rails'；默认迁移生成器模板

我需要覆盖这些迁移模板：

及

在我的rails应用程序内部，这样他们就可以从rails应用程序而不是gem本身获取模板。到目前为止，我已经尝试了所有可能的组合，但没有成功

我所尝试的：

- Rails.root/lib/templates/rails/migration/migration.rb
- Rails.root/lib/templates/rails/migration_generator/migration.rb
- Rails.root/lib/rails/templates/rails/migration/migration.rb
- Rails.root/lib/rails/templates/rails/migration_generator/migration.rb
- Rails.root/lib/rails/generators/templates/rails/migration/migration.rb
- Rails.root/lib/rails/generators/templates/rails/migration_generator/migration.rb
- Rails.root/lib/rails/templates/generators/rails/migration/migration.rb
- Rails.root/lib/rails/templates/generators/rails/migration_generator/migration.rb
- Rails.root/lib/rails/generators/active_record/migration/templates/migration.rb
- Rails.root/lib/rails/generators/active_record/migration_generator/templates/migration.rb
- Rails.root/lib/rails/generators/active_record/templates/migration.rb
- Rails.root/lib/rails/generators/active_record/templates/migration.rb

有人能给我指出正确的方向吗？

我想出了一个解决方案：

我用这个命令创建了一个Rails生成器（在我的Rails应用程序目录中）-

它创造了：

lib/generators/my_migrator/my_migrator.rb
lib/generators/my_migrator/templates
lib/generators/my_migrator/USAGE

然后，我将此代码添加到my_generator.rb中，以扩展生成器中的rails迁移生成器：

require 'rails/generators'
require 'rails/generators/active_record'
require 'rails/generators/actions/create_migration'

class MyGenerator < ActiveRecord::Generators::Base
  source_root File.expand_path('../templates', __FILE__)
  argument :attributes, :type => :array, :default => [], :banner => "field[:type][:index] field[:type][:index]"

  def create_migration_file
    set_local_assigns!
    validate_file_name!
    migration_template @migration_template, "db/migrate/#{file_name}.rb"
    # more code here as per requirement.
  end

  # more code below as per requirement..
end

要求“轨道/发电机”
需要“轨道/发电机/活动记录”
需要“rails/generators/actions/create_迁移”
类MyGenerator：数组，：default=>[]，：banner=>“字段[：type][：index]字段[：type][：index]”
def创建_迁移_文件
设置\u本地\u分配！
验证文件名！
migration_template@migration_template，“db/migrate/#{file_name}.rb”
#根据需要在此处添加更多代码。
结束
#根据要求，更多代码如下。。
结束

把这个贴在这里，希望将来有一天能对别人有所帮助

require 'rails/generators'
require 'rails/generators/active_record'
require 'rails/generators/actions/create_migration'

class MyGenerator < ActiveRecord::Generators::Base
  source_root File.expand_path('../templates', __FILE__)
  argument :attributes, :type => :array, :default => [], :banner => "field[:type][:index] field[:type][:index]"

  def create_migration_file
    set_local_assigns!
    validate_file_name!
    migration_template @migration_template, "db/migrate/#{file_name}.rb"
    # more code here as per requirement.
  end

  # more code below as per requirement..
end
