Rails:参数数量错误(给定2个，预期为1个)MongoID [英] Rails: Wrong number of arguments (given 2, expected 1) MongoID

问题描述

我正在尝试打开MongoDB模型，但是，出现以下错误:

I'm trying to open my MongoDB models, however, I'm getting the following error:

MONGODB | xxx.xx.x.xxx:27017 | db.find | FAILED | wrong number of arguments (given 2, expected 1) | 0.013306s

我的Mongo凭据是正确的，我可以在Rails外部连接到数据库的集合.

My Mongo credentials are correct, and I can connect to the database's collections outside of Rails.

该错误的前几行是:

Started GET "/admin/xsl_sheet" for xxx.xxx.xxx.xxx at 2020-03-03 13:49:54 UTC

    /GEMS/gems/bson-4.8.0-java/lib/bson/hash.rb:115:in `from_bson'

这是rails_admin.rb中的代码(我相信)负责从MongoDB中提取对象:

Here is the code inside rails_admin.rb which (I believe) is in charge of pulling objects from MongoDB:

c.model XslSheet do
  label Proc.new {"Xsl Sheet"}
  navigation_label Proc.new {I18n.t('navigation.actions')}
  weight 303
  navigation_icon 'fa fa-file-excel-o'
  list do
    scopes [:applicationId]
    field :data_file_name
    field :updated_at
  end
end

推荐答案

这是 https://jira.mongodb.org/browse/RUBY-2146 .降级到bson 4.7.0，直到发布4.8.2.

This is https://jira.mongodb.org/browse/RUBY-2146. Downgrade to bson 4.7.0 until 4.8.2 is released.

为帮助人们回答您的问题，请包括您使用的软件版本(在这种情况下，mongoid，mongo和bson版本是相关的)，以及您正在使用JRuby的事实.
