找不到Mongoid会话

Question

尝试使用Sinatra \ Mongoid 3。每当我试图保存到数据库时，都会遇到以下错误。

Mongoid::Errors::NoSessionsConfig: 
Problem:
 No sessions configuration provided.
Summary:
Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
    Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.

Example:
 development:
    sessions:
     default:
        database: mongoid_dev
     hosts:
      - localhost:27017

from /Users/rhodee/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/mongoid-3.0.13/lib/mongoid/sessions/factory.rb:61:in `create_session'

我已经确认了以下内容：

• 加载Mongoid.yml文件
• 哈希包含正确的环境和db名称。

使用Mongoid.load!方法返回的返回值如下：

=> {"sessions"=>
 {"default"=>
 {"database"=>"bluster",
 "hosts"=>["localhost:27017"],
 "options"=>{"consistency"=>"strong "}}}}

如果是帮助检查，我还添加了app.rb文件和mongoid.yml文件。

App.rb

require 'sinatra'
require 'mongoid'
require 'pry'
require 'routes'
require 'location'

configure :development do
 enable :logging, :dump_errors, :run, :sessions
 Mongoid.load!(File.join(File.dirname(__FILE__), "config", "mongoid.yml"))
end

Mongoid.yml

 development:
   sessions:
     default:
      database: bluster
      hosts:
        - localhost:27017
      options:
       consistency: strong 

Answer 1

require 'sinatra'
require 'mongoid'
require 'pry'
require 'routes'

configure :development do
  enable :logging, :dump_errors, :run, :sessions
  Mongoid.load!(File.join(File.dirname(__FILE__), "config", "mongoid.yml"))
end

get '/db' do
  "db: " <<  Mongoid.default_session[:moped].database.inspect
end

我举了一个例子，这个例子对我来说很好。您的问题可能是其他问题，比如没有读取访问权限的配置文件或其他什么东西。无论如何，我的配置文件与您的配置文件相同，这是我的sinatra文件，并且工作正常。
