添加属性的思维狮身人面像索引配置导致索引失效

Question

定模式：

create_table "letters", force: :cascade do |t| 
t.string "title",  limit: 255 
t.text  "content", limit: 16777215 
t.date  "issue_date" 
t.datetime "created_at",     null: false 
t.datetime "updated_at",     null: false 
t.integer "osha_id", limit: 4 
t.string "status",  limit: 255 
end 

指数/ letter_index.rb

ThinkingSphinx::Index.define :letter, :with => :real_time do 
# fields 
indexes title, :sortable => true 
indexes content 
indexes issue_date_as_string 

# attributes 
has status, :type => :string 
has created_at, :type => :timestamp 
has updated_at, :type => :timestamp 
end 

当我rake ts:regenerate没有has status, :type => :string线，它生成的索引就好了。

但是，当我再补充一点线，我得到错误信息一屏，其中最相关的似乎是

/home/tim/.rvm/gems/ruby-2.2.1/gems/rake-12.0.0/exe/rake:27:in '<top (required)>' 
Mysql2::Error: unknown column: 'status' 

我绝对什么错误是想告诉我迷惑和为什么它首先失败。我错过了明显的东西吗？

完全错误输出（它转储数据库的内容后）：

进一步没来由information--这说明我已经试过各种事情，所有这些都失败，同样的错误unknown column：

ThinkingSphinx::Index.define :letter, :with => :real_time do 
    # fields 
    indexes title, :sortable => true 
    indexes content 
    #indexes issue_date 
    indexes issue_date_as_string # this one works! 
    #indexes status 
    #indexes status_as_string 
    #indexes osha_id 
    #indexes issue_date 

    # attributes 
    #has status, :type => :string 
    has created_at, :type => :timestamp 
    has updated_at, :type => :timestamp 
end 

的*_as_string方法只是在黑暗中拍摄：

个

型号/ letter.rb：

# experimental for thinking sphinx indexing on issue date 
def issue_date_as_string 
    self.issue_date.to_s 
end 

def status_as_string 
    self.status.to_s 
end 

Answer 1

感谢所有额外的细节添。

我觉得这里的问题是关系到一个错误的思维狮身人面像导致索引文件不被​​妥善清理出去，因此他们仍然使用旧的模式（不status属性）。这意味着任何尝试填充新数据都会导致该错误。

不过，我已经修复了这个bug，而思维狮身人面像的v3.3.0版本包含了它。你可以升级（有no breaking changes），看看是否解决了这个问题？
