ruby - 如何确定 Rails 3 模型类中的表名

Question

我想在模型方法中获取表名。我 found应该有方法 table_name 但是当我尝试调用它时我得到 NameError Exception: undefined local variable or method `table_name'。显然不存在:

 pp methods.grep(/^ta.*/)
["table_name_prefix?",
 "table_name_suffix?",
 "taint",
 "taguri",
 "taguri=",
 "tainted?",
 "table_name_prefix",
 "table_name_suffix",
 "tap"]

如何获得“真实的”表名(无小写 - 复数技巧)？

谢谢

But I need that information in the model's instance method. How to get it?

您可以在实例方法中简单地执行此操作:

class Model
  def instance_method
    puts Model.table_name
  end
end
