如何使用“ActiveModel::Errors”将错误附加到类中模块
我正在使用 Ruby on Rails 3，并且尝试按顺序扩展类帐户 以“Rails 方式”处理错误。
在我的模型中，我
class Users::Account
extend ActiveModel::Naming
extend ActiveModel::Translation
include ActiveModel::Validations
include ActiveModel::Conversion
def persisted?
false
end
attr_reader :errors
def initialize(attributes = {})
@errors = ActiveModel::Errors.new(self)
@firstname = attributes[:firstname]
@lastname = attributes[:lastname]
...
end
end
想使用 ActiveModel::Errors 在上面的类中“封装”以下哈希，
---
errors:
base: Invalid account.
firstname: Too short.
以便在类中插入上述错误哈希后，我可以这样做，如下所示
@account.errors # => Hash of errors
测试场景的调试（总是）如下，因为我不知道如何将错误附加到类中。
firstname: T
lastname: Test surname
errors: !omap []
我该怎么做？
I am using Ruby on Rails 3 and I am trying to exend a class Account in order to handle errors "a la Rails way".
In my model I have
class Users::Account
extend ActiveModel::Naming
extend ActiveModel::Translation
include ActiveModel::Validations
include ActiveModel::Conversion
def persisted?
false
end
attr_reader :errors
def initialize(attributes = {})
@errors = ActiveModel::Errors.new(self)
@firstname = attributes[:firstname]
@lastname = attributes[:lastname]
...
end
end
I would like to "encapsulate" in the above class the following hash using the ActiveModel::Errors
---
errors:
base: Invalid account.
firstname: Too short.
so that I can do, after inserting the above error hash in the class, like this
@account.errors # => Hash of errors
A debug for a testing scenario is (always) the following because I don't know how to append errors to the class.
firstname: T
lastname: Test surname
errors: !omap []
How can I do that?
