Question

我正在关注M. Hartl教程，我有一个我无法理解的错误。我想用假用户填充我的数据库，首先是rake db:reset，然后是rake db:populate，但它失败了。

以下是代码：

LIB /任务/ sample_data.rake

namespace :db do
  desc "Fill database with sample data"
  task populate: :environment do
    admin = User.create!(name: "Example User",
                 email: "example@apptesting.com",
                 password: "motdepasse",
                 password_confirmation: "motdepasse",
                 admin: true)
    99.times do |n|
      name  = "User #{n+1}"
      email = "user-#{n+1}@apptesting.com"
      password  = "motdepasse"
      User.create!(name: name,
                   email: email,
                   password: password,
                   password_confirmation: password)
    end
  end
end

rake db:populate

之后的结果

$ rake db:populate --trace
** Invoke db:populate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:populate
rake aborted!

是否有人能够理解这种胡言乱语并向我解释？

Answer 1

尝试将此文件：https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/fr.yml放在 config / locales / 文件夹中，它只是说您的记录无效，但它无法在fr中找到相应的消息。区域设置

Answer 2

好像你有验证错误。检查您的用户模型以获取验证，然后尝试查找失败的模型。

如果您无法找到哪一个验证失败，请尝试从具有相同属性的控制台创建用户。

user = User.new({ 'Your attributes' })
user.valid?
user.errors.messages

Answer 3

看起来您的admin属性有误。除非您将管理员添加到attr_accessible，否则无法批量指定管理员。如果你确实添加了这是一个糟糕的安全漏洞。基本上任何人都可以通过命令行使自己成为管理员。以下是将admin添加为true的方法：

admin.toggle!(:admin)

尝试一下，让我知道它是否有效

db的有趣错误：populate和I18n：fr.activerecord.errors.messages.record_invalid
