我正在尝试让一个可以在 vagrant 上运行的 linux 10.04 上运行的应用程序

我安装了所有相关的 gem,安装了 postgresql 9.1.9,当我尝试运行 rake db:migrate时,我得到了

rake aborted!

Tasks: TOP => db:migrate => environment

runningrake db:create:all告诉我所有表都已创建

我不知道这是否重要,但我使用的是 devise 2.2.4 和最新的acts_as_messageable。

请注意,此应用程序确实可以在 Windows 开发机器上运行,并在 heroku 中进行生产。我只想让它也可以在 vagrant 上运行。

我的 database.yml 是

common: &common

      adapter: postgresql
      enconding: utf8
      host: localhost
      username: postgres
      password: 1234
      pool: 5
      timeout: 5000
    development:
      <<: *common
      database: myapp_dev
      port: 5432
    test:
      <<: *common
      database: myapp_test

    production:
      <<: *common
      database: myapp_prod

我怀疑它与一些 postgres 配置有关,但我不确定.. 还没有找到任何解决方案

当检查 psql 我得到这个

postgres=# \l
                                   List of databases
    Name     |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges

             |          |          |             |             | postgres=CTc/postgres
 template1   | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
             |          |          |             |             | postgres=CTc/postgres
 myapp_dev  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 myapp_prod | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 myapp_test | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
(6 rows)

postgres=# \d myapp_dev
Did not find any relation named "myapp_dev".

所以我认为这里出了点问题..有解决方案吗?

注意 - 这发生在rake db诸如schema:load, setup..

如果需要 - 这是与acts_as_messageable相关的错误中的相关行,包括迁移文件

用户:120-123行

acts_as_messageable :table_name => "messages", 
                    :required   => :body,

消息类(第 25-29 行)

class Message < ActsAsMessageable::Message

attr_accessible :sender_open, :reciever_open
scope :unread_by, lambda{ |user| where("reciever_open = false AND received_messageable_id = ?", user.id)}
scope :unread, where('reciever_open = false')

迁移文件 - 20121127082447_create_messages_table.rb (它不是第一个或最后一个,在中间的某个地方)

class CreateMessagesTable < ActiveRecord::Migration
  def self.up
    create_table :messages do |t|
      t.string :topic
      t.text :body
      t.references :received_messageable, :polymorphic => true
      t.references :sent_messageable, :polymorphic => true
      t.boolean :opened, :default => false
      t.boolean :recipient_delete, :default => false
      t.boolean :sender_delete, :default => false
      t.timestamps

      # ancestry
      t.string :ancestry
    end

    add_index :messages, [:sent_messageable_id, :received_messageable_id], :name => "acts_as_messageable_ids"
    add_index :messages, :ancestry
  end

  def self.down
    drop_table :messages
  end
end

Rails 中的Routes文件使用device_for,它加载 User 模型,而后者又拥有acts_as_messagable并加载Message类。第 29 行在Message课堂上说:

scope :unread, where('reciever_open = false')

where方法正在触发列查找,但由于迁移尚未运行而失败!尝试以下两种方法之一:

将其更改为:

scope :unread, where(:reciever_open => false)

或者,如果这也触发了列查找,那么说:

scope :unread, lambda { where('reciever_open = false') }

只是想在这里检查一下显而易见的事情,但是您尝试过跑步rake db:drop吗?每当我对迁移进行更改时,我都需要在尝试创建和迁移它们之前删除所有数据库表。

所以完整的操作将是rake db:drop db:create db:migrate

哦,你也可以尝试指定环境(我有时需要在测试环境中这样做),例如rake RAILS_ENV=test db:drop db:create db:migrate
