の追加属性が

Question

指定されたスキーマを失敗：

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 

インデックス/ letter_index.rb私はhas status, :type => :stringラインなしで、それがうまくインデックスを生成rake ts:regenerate

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 

。最も関連が私は絶対にエラーが私に伝えようとしているもので混乱してる

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

であるように思われたの

しかし、私はその行を追加するとき、私は、エラーメッセージの画面分を取得し、なぜそれが最初に失敗したのか。私は明白な何かを欠いていますか

完全なエラー出力（それはデータベースの内容をダンプした後）

さらに無償で私が試したいろいろなことを示しています

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方法は暗闇の中でだけでショットです：：、すべてが同じunknown columnエラーで失敗している

モデル/ 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

は、すべての余分なディテールティムを感謝しています。

ここでの問題はThinking Sphinxのバグと関連しており、インデックスファイルが​​によって正しくクリアされていないため、まだ古いスキーマ（status属性なし）を使用していると考えられます。つまり、新しいデータを設定しようとすると、そのエラーが発生します。

しかし、私は少し前にこのバグを修正しました。Thinking Sphinxのv3.3.0リリースにも含まれています。アップグレードすることができますか（no breaking changes）、それが問題を解決するかどうか確認してください。
