ruby-on-rails – 使用database_cleaner,mongoid和active_admin

我有一个使用mongoid,database_cleaner和rspec的现有项目.我尝试使用 active_admin patches available添加active_admin.ActiveAdmin假定它在ActiveRecord项目中,最具体的是通过它对meta_search gem的依赖.

当我去运行我的规格时,它们都会因以下错误而失败：

Failure/Error: Unable to find matching line from backtrace
ActiveRecord::ConnectionNotEstablished:
  ActiveRecord::ConnectionNotEstablished
# ./spec/support/database_cleaner.rb:12:in `block (2 levels) in <top (required)>'

相关库的gem版本如下：

> activeadmin(0.4.2)
> database_cleaner(0.7.1)
> mongoid(2.4.5)
> meta_search(1.1.3)
> activerecord(3.2.1)

测试失败的文件,spec / support / database_cleaner.rb：

require 'database_cleaner'

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.strategy = :truncation
    DatabaseCleaner.orm = "mongoid"
  end

  config.before(:each) do
    DatabaseCleaner.clean
  end
end

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner[:mongoid].strategy = :truncation
  end
end
