尝试填充我的sqlite数据库时遇到问题.关于特定错误"finder_needs_type_condition？"的信息不多.我可以找到,但我对Rails没有多少经验,甚至怀疑问题可能在哪里.

  def create
    @characters = Character.all
    @character = Character.create(character_params)
  end

  private
    def character_params
      params.require(:character).permit(:user_id, :name, :class)
    end

  t.datetime "created_at",             null: false
  t.datetime "updated_at",             null: false
  t.string   "name"
  t.string   "class"
  t.integer …
