这是我尝试创建新模型时日志中的错误：

它来自 has_many_polymorphs 插件...
这里是 config/environment.rb:
# Load the rails application
require File.expand_path('../application', __FILE__)
# Initialize the rails application
Dreamstill::Application.initialize!
这是/rubyprograms/dreamstill/vendor/plugins/has_many_polymorphs/lib/has_many_polymorphs/configuration.rb：
module Rails #:nodoc:
class Configuration
def has_many_polymorphs_options
::HasManyPolymorphs.options
end
def has_many_polymorphs_options=(hash)
::HasManyPolymorphs.options = HashWithIndifferentAccess.new(hash)
end
end
end
【问题讨论】：
-
一如既往，您没有显示任何代码，所以我们应该想象是什么导致了错误：D。显示您的
config/environment.rb代码:) -
没什么有趣的:)。因此，此文件和第 23 行中的插件内部存在问题：
/rubyprograms/dreamstill/vendor/plugins/has_many_polymorphs/lib/has_many_polymorphs.rb:23。
