rake db：migrate我得到了

Tasks: TOP => db:migrate => environment
运行rake db：create：all告诉我所有表都已创建
我不知道它是否重要,但我使用的是设计2.2.4和最新的acts_as_messageable.
请注意,这个应用程序适用于Windows开发机器和heroku生产..我只是想让它在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..无法找到任何解决方案
检查psql时我得到了这个
postgres=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-------------+----------+----------+-------------+-------------+-----------------------
postgres | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres +

template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/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".
所以我觉得有些不对劲……有解决方案吗？
注意 – 这发生在rake db任务中,例如schema：load,setup ..
如果需要,这里是与acts_as_messageable相关的错误的相关行,包括迁移文件
用户：第120-123行
acts_as_messageable :table_name => "messages",
:required => :body,
:class_name => "Message",
:dependent => :destroy
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,位于中间某处)
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
解决方法:
Rails中的Routes文件使用device_for,它加载User模型,而User模型又具有acts_as_messagable并加载Message类. Message类中的第29行说：
范围：未读,其中(‘reciever_open = false’)
where方法触发列查找,因为迁移尚未运行而失败！尝试以下两种方法之一：
将其更改为：
范围：未读,其中(：reciever_open => false)
或者,如果这也触发列查找,则说：
范围：未读,lambda {where(‘reciever_open = false’)}
