奇妙なエラーがあります。単体テストを実行しようとすると、次のエラーが表示されます。

test_the_truth(UpdateMainTest):

これは私のブラックリストモデルです:

class Blacklist < ActiveRecord::Base
  attr_accessible :abbreviation, :name
  self.table_name = "blacklist"
  validates :abbreviation, :presence => :true, :uniqueness => :true
  validates :name, :presence => :true
end

スキーマには、テーブルも正しくリストされています。

  create_table "blacklist", :force => true do |t|
    t.string   "name"
    t.string   "abbreviation"
    t.datetime "created_at",   :null => false
    t.datetime "updated_at",   :null => false
  end

rake db:test:prepare を複数回実行しましたが、エラーは残ります。Rails コンソールを使用すると、エラーなしでブラックリスト オブジェクトを作成できます。私に何ができるか考えていますか？

複数形の記号を使用します。テーブル名は複数形にする必要があります。

self.table_name = :blacklists

複数形でテーブル名を作成:

create_table "blacklists", :force => true do |t|
    t.string   "name"
    t.string   "abbreviation"
    t.datetime "created_at",   :null => false
    t.datetime "updated_at",   :null => false
  end
