如何将我的 rails 自定义生成器附加到模型一?
How do I attach my rails custom generator to the model one?
目前,我创建了一个独立的生成器。当我 运行 rails g query
时,它可以正常工作并很好地创建我的文件。
这里是代码:
# lib/generators/rails/query_generator.rb
require_relative '../my_lib/named_base'
module Rails
module Generators
class QueryGenerator < MyLib::Generators::NamedBase
source_root File.expand_path('templates', __dir__)
check_class_collision suffix: 'Query'
def create_model_query
return if class_name.blank?
template_file = File.join('app/queries', class_path, "#{file_name}_query.rb")
template 'query.rb.erb', template_file
end
end
end
end
现在,我想 运行 生成器当人们 运行 rails g model
但我无法实现。
我尝试覆盖生成器模型 class 并使用 hook_for
来调用它,但它不起作用。这里的代码:
# lib/generators/rails/model_generator.rb
require "rails/generators"
require "rails/generators/rails/model/model_generator"
require_relative './query_generator'
module Rails
module Generators
class ModelGenerator < ::Rails::Generators::ModelGenerator
hook_for :orm, as: :model, in: :rails do |instance, model|
instance.invoke Rails::Generators::QueryGenerator, [ instance.name ]
end
end
end
end
希望你能帮助我。谢谢!
终于,我找到了解决办法!在 Railtie 的帮助下,我可以从 rails 模型生成器实现预期的行为挂钩。
# lib/my_gem.rb
require ...
require 'my_gem/railtie' if defined?(Rails)
# lib/my_gem/railtie.rb
require 'rails/railtie'
module ActiveModel
class Railtie < Rails::Railtie
generators do |app|
Rails::Generators.configure! app.config.generators
require_relative '../generators/model_generator'
end
end
end
# lib/generators/model_generator.rb
require 'rails/generators'
require 'rails/generators/rails/model/model_generator'
require_relative 'rails/query_generator'

module Generators
class ModelGenerator
hook_for :query, type: :boolean, default: true
end
