将属性添加到 thinking sphinx 索引配置导致索引失败
Adding attribute to thinking sphinx index config causing indexing fail
给定架构：
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
indices/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 行时，它生成索引就好了。
但是当我添加该行时，我会收到一屏错误消息，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'
我对错误试图告诉我的内容以及它为什么首先失败感到非常困惑。我是否遗漏了一些明显的东西？
