Ruby on rails 未知属性'；成绩'；寻求反馈

我有以下错误：

“赞扬“成绩工作”以获得反馈。”

链接中是rails控制台的屏幕，发送的参数包括：

"{" feedback "=> {" anotations "=>" Holiiii "," score "=>" 12 " 1 "," user "=>" # <User: 0x007f4674123f38> "}}"

反馈控制器：

def create
     @feedback = Feedback.new(feedback_params)
    respond_to do |format|
      if @feedback.save!
        format.html { redirect_to @feedback, notice: 'Feedback was successfully created.' }
        format.json { render :show, status: :created, location: @feedback }
      else
        format.html { render :new, notice: 'Feedback was not created.' }
        format.json { render json: @feedback.errors, status: :unprocessable_entity }
      end
    end
  end   

def feedback_params
      params.require(:feedback).permit(:anotations, :score, :gradework, :user)
    end

视图：

“Ninguno”，类：“表单控制”，名称：“反馈[成绩]”）%>

我不知道怎么了

您应该有两件事来创建成绩工作条目以及您视图中的反馈条目：

属于
反馈
模型中的成绩工作

表单中的名称应为

feedback[gradework\u attributes]

，而不是

feedback[gradework]

---

问题似乎在这里：

<%= select_tag(:gradework, options_from_collection_for_select(@grad_jury ,:id, :name), :prompt => "Ninguno", class: "form-control", name: "feedback[gradework]") %>

---

这将把

gradework\u id

作为参数发送，无论在

select

中选择了什么值，请尝试设置

gradework

而不是视图中的

gradework\u id

。您可以共享您的视图吗（

new.html.erb

）？现在添加视图，这是查询“def self.users\u gradework（id）joins（：users）。选择（“gradeworks.id，gradeworks.name，gradeworks.description”）。其中（{users:{id:id}）end“关系是”has_和_属于_many:gradeworks当我更改关系时，我得到以下错误“预期成绩（#699702355955560），获得字符串（#15868000）”。按成绩id更改成绩，但错误仍在继续。@SebastianMoralesGarzón在错误屏幕中，您现在在参数方面得到了什么：？如果是这样，还有一个细节，非常感谢
