Rails - 异常 I18n::InvalidLocale 在一个奇怪的地方

Question

有时 Rails 很漂亮，但有时却很糟糕。尤其是当你遇到奇怪的异常时

我有 3 个简单的模型

/app/models/specification_type.rb

class SpecificationType  < ActiveRecord::Base#< AbstractModel

  has_many :scpecification_type_to_category_relations, class_name: "Relations::SpecificationTypeToCategory"
  has_many :categories, through: :scpecification_type_to_category_relations  

end

/app/models/category.rb

class Category < ActiveRecord::Base#AbstractModel

  has_many :groups
  has_many :products

  has_many :scpecification_type_to_category_relations, class_name: "Relations::SpecificationTypeToCategory"
  has_many :specification_types, through: :scpecification_type_to_category_relations  

end

/app/models/relations/specification_type_to_category.rb

class Relations::SpecificationTypeToCategory < ActiveRecord::Base

  self.table_name = "specification_type_to_category_relations"

  belongs_to :scpecification_type
  belongs_to :category

end

迁移20141231115801_create_specation_types.rb

每次在任何地方（视图或控制台），当我尝试调用 @category.specation_types 时，都会出现异常：

I18n::InvalidLocale: :en is not a valid locale

导轨c

Category.first.specification_types
  Category Load (0.3ms)  SELECT  `categories`.* FROM `categories`  ORDER BY `categories`.`id` ASC LIMIT 1
I18n::InvalidLocale: :en is not a valid locale

....

我不明白 I18n 在哪里

我在项目中使用了 I18n，但这里没有。有 2 个语言环境，但我根本不使用 :en locale。

请帮帮我。

Answer 1

这个错误是非常原始的。: 规范类型中的额外字母“c”。但要查看我在 application.rb 中设置的人类可读的异常

config.i18n.enforce_available_locales = false
