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
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行时，它会生成索引。
但是当我添加该行时，我会收到一些错误消息，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'
我对于错误试图告诉我的错误以及为什么它首先失败感到非常困惑。我错过了一些明显的东西吗？

进一步的无偿信息 - 这显示了我尝试过的各种事情，所有事情都因同一个unknown column错误而失败：
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
*_as_string方法只是在黑暗中拍摄：
模型/ 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
答案 0 :(得分：0)
欣赏所有额外的细节蒂姆。
我认为这里的问题与Thinking Sphinx中的一个错误有关，导致索引文件无法被ts:regenerate正确清除，因此他们仍在使用旧架构（没有status属性）。这意味着任何填充新数据的尝试都会遇到错误。
但是，我刚刚修复了这个bug，而Thinking Sphinx的v3.3.0版本包含了它。你可以升级（有no breaking changes）并查看是否能解决问题吗？
