MongoMapper 中的键名称冲突

发布于 2024-11-06 09:41:37 字数 477 浏览 0 评论 0原文

我在 sinatra 服务中使用 mongo mapper (0.8.6)。我有一个问题，堆栈级别太深。问题是我的模型中的关键“changes”存在冲突。这是我的模型：

class ChangeLog
  include MongoMapper::Document

  belongs_to :resource

  key :changes, Hash, :required => true
  key :message, String, :required => true
  key :note, String
  key :user_uuid, String, :required => true
  key :user_name, String, :required => true
  timestamps!
end

但是，我不想重命名我的密钥，因为在本例中，它是我的 Web 服务的正确名称。有什么建议吗？

I use mongo mapper (0.8.6) in my sinatra service. I have one problem with stack level too deep. The problem is that there is conflict of the key "changes" in my model. Here is my model:

class ChangeLog
  include MongoMapper::Document

  belongs_to :resource

  key :changes, Hash, :required => true
  key :message, String, :required => true
  key :note, String
  key :user_uuid, String, :required => true
  key :user_name, String, :required => true
  timestamps!
end

However, I don't want to rename my key as in this case, it's the right name for my web service. Any suggestions?

changes 是一个实例方法，它会告诉您自上次保存文档以来哪些字段发生了更改。这是 MongoMapper 文档中的示例

user = User.create(:name => 'John', :age => 29)

puts user.changed?        # false
puts user.changes.inspect # {}

user.name = 'Steve'
puts user.changed?            # true
puts user.changes.inspect     # {"name"=>["John", "Steve"]}

不幸的是，您可能需要选择不同的该字段的名称。也许是“调整”或“变化”或“差异”或“修改”？

changes is an instance method that will tell you what fields have changed since you last saved the document. Here's an example from MongoMapper's documentation

user = User.create(:name => 'John', :age => 29)

puts user.changed?        # false
puts user.changes.inspect # {}

user.name = 'Steve'
puts user.changed?            # true
puts user.changes.inspect     # {"name"=>["John", "Steve"]}

Unfortunately, you're probably going to need to choose a different name for that field. Maybe "adjustments" or "variations" or "differences" or "modifications"?
