Ruby 无法将印象派模型添加到Solr

为了跟踪我添加的独特视图。由于流量增加，印象表将以更快的速度增长。当我以后想要显示连续周/月之间的比较时，这将导致问题

所以我想把impression的模型与solr链接起来

为了实现这一点，我首先在

app/models/impression.rb

文件夹下创建了一个名为impression的模型

class Impression < ActiveRecord::Base

    attr_accessible :user_id, :ip_address, :action_name, :controller_name, :impressionable_type, :impressionable_id, :view_name, :session_hash, :message, :request_hash, :referrer

    searchable :ignore_attribute_changes_of => [ :updated_at] do
        text :message, :boost=> 2.0
        text :referrer
        text :ip_address
        integer :user_id
        time :created_at
        time :updated_at       
        string :message
        string :view_name
        string :ip_address
        string :impressionable_type 
        string :controller_name
        string :action_name
        string :session_hash
        string :request_hash
        integer :id
        integer :impressionable_id   
      end
end

接下来，我尝试使用solr查询

Impression

model

search = Sunspot.search Impression do
      with(:impressionable_type).equal_to('Blogpost')
      with(:impressionable_id).equal_to(1)
    end.total
    puts "total results #{search || 0}"
search

上述代码不断抛出此错误：

有人能告诉我如何创建一个Impression模型，以便与solr一起使用吗？

通过在

config/initializers/impressive_patch.rb

下添加相同的模型定义，解决了这个问题：

class Impression < ActiveRecord::Base

    attr_accessible :user_id, :ip_address, :action_name, :controller_name, :impressionable_type, :impressionable_id, :view_name, :session_hash, :message, :request_hash, :referrer

    searchable :ignore_attribute_changes_of => [ :updated_at] do
        text :message, :boost=> 2.0
        text :referrer
        text :ip_address
        integer :user_id
        time :created_at
        time :updated_at       
        string :message
        string :view_name
        string :ip_address
        string :impressionable_type 
        string :controller_name
        string :action_name
        string :session_hash
        string :request_hash
        integer :id
        integer :impressionable_id   
      end
end

类印象[：更新时间]do
text:message，：boost=>2.0
文本：推荐人
文本：ip地址
整数：用户id
时间：创建于
时间：更新于
字符串：消息
字符串：视图名称
字符串：ip_地址
字符串：易受影响的类型
字符串：控制器名称
字符串：操作名称
字符串：会话\u哈希
字符串：请求\u散列
整数：id
整数：易受影响的\u id
结束
结束

我能够在这个文件中定义我自己的类和实例方法

class Impression < ActiveRecord::Base

    attr_accessible :user_id, :ip_address, :action_name, :controller_name, :impressionable_type, :impressionable_id, :view_name, :session_hash, :message, :request_hash, :referrer

    searchable :ignore_attribute_changes_of => [ :updated_at] do
        text :message, :boost=> 2.0
        text :referrer
        text :ip_address
        integer :user_id
        time :created_at
        time :updated_at       
        string :message
        string :view_name
        string :ip_address
        string :impressionable_type 
        string :controller_name
        string :action_name
        string :session_hash
        string :request_hash
        integer :id
        integer :impressionable_id   
      end
end
