比较rspec自定义ActiveRecord :: RecordInvalid错误消息 [英] Comparing rspec custom ActiveRecord::RecordInvalid errors messages

问题描述

模型中具有以下内容：

validates_uniqueness_of :title,
    if: proc { |item| item.item_type == 'tag' },
    case_sensitive: false,
    message: I18n.t('errors.key', value: "%{value}")

并尝试在rspec中使用以下命令进行验证：

and trying to validate in rspec with the following :

expect { xxx }.to raise_error(
    ActiveRecord::RecordInvalid,
    I18n.t('errors.key', value: '...passing the title...')
)

我被紧紧的跟随着：

ActiveRecord::RecordInvalid with "translated error",
got #<ActiveRecord::RecordInvalid: Validation failed: translated error>

期望值等待一个没有报价的值，而发送的值带有报价；

The expectation awaits a value without quote, while the value sent has quote; it fails on that

我在默认设置下遇到了同样的错误：

I get the very same error with the default setup :

activerecord:
    errors:
      models:
        item:
          attributes:
            title:
              taken: 'translated error'

同一测试通过以下测试：

The same test passes with the followings :

期望{xxx}。以提高错误

期望{xxx}。以提高错误（ActiveRecord :: RecordInvalid）

使用默认设置也是如此：

So does using the default setup :

感谢任何帮助

推荐答案

ActiveRecord将前缀 Validation failed：添加到错误信息。相反，请在测试中尝试以下操作：

ActiveRecord adds the prefix Validation failed: to the error message. Try this in your test instead:

expect { xxx }.to raise_error(
  ActiveRecord::RecordInvalid,
  "Validation failed: " + I18n.t('errors.key', value: '...passing the title...')
)

您可以通过在语言文件中设置以下键来更改此默认值：

You can change this default by setting the following key in your language file:

en:
  activerecord:
    errors:
      messages:
        record_invalid: "Validation failed: %{errors}"
