未知屬性「gradework」的反饋

"tribute 'gradework' for Feedback."

在鏈接是Rails控制檯的屏幕和發送的參數是：

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

    def change 
    create_table :feedbacks do |t| 
     t.text :anotations

     t.references :gradework, foreign_key: true 
     t.references :user, foreign_key: true 
     t.timestamps 
    end 
    end 
end

feedbackController：

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

觀點：

<form role="form" id="newForm" action="/feedbacks" method="post"> 

     <div class="form-group">   
      Comentario:<br> 
      <textarea type="text" rows="5" class="form-control" 
      id="inputAnotations" placeholder="Ingrese su comentario"             name="feedback[anotations]" required></textarea> 
     <br><br> 
     </div> 
     <div class="form-group"> 
       Score:<br> 
       <input type="number" class="form-control" name="feedback[score]"> 
    </div> 
    <div class="form-group"> 
      <label for="gradework">Tesis:</label> 
      <%= select_tag(:gradework, options_from_collection_for_select(@grad_jury ,:id, :name), :prompt => "Ninguno", class: "form-control", name: "feedback[gradework]") %> 
    </div> 
    <div class="form-group"> 
      <%#User:<br>%> 
      <input type="hidden" class="form-control" name="feedback[user]" value= <%= @cUser %>> 
    </div> 

     <br><br> 
    <button type="submit" class="btn btn-default" data-dismiss="">Agregar</button> 
    <!-- <input type="submit" value="Agregar"> --> 
</form>

我不知道什麼是錯的！

嘗試在視圖中設置'gradework'而不是'gradework_id'。你能分享你的看法嗎（'new.html.erb'）？ – Gerry

現在添加視圖，這是查詢「def self.users_gradework（id） joins（：users）.select（」gradeworks.id，gradeworks.name，gradeworks.description「） .where（{users：{ id：id}}） end「 –

關係是」has_and_belongs_to_many：gradeworks「 –

這個問題似乎是在這裏：

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

您的形式發送gradework屬性，是不是在你的模型（Feedback），所以你需要發送gradework_id來代替，所以請嘗試將上述行改爲：

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

這會發送gradework_id作爲參數，無論在select中選擇了什麼值。

按gradework_id更改成績，但錯誤仍在繼續。 –

@SebastianMoralesGarzón在你的錯誤屏幕上，你現在得到什麼**參數：**？ – Gerry

如果是再加上一個細節，非常感謝 –

你應該有2兩件事情從你的觀點反饋詞條沿創建gradework項：

belongs_to :gradework在Feedback模型。
形式的名稱應爲feedback[gradework_attributes]，而不是feedback[gradework]

當我更改關係時，出現以下錯誤」Gradework（＃69970235955560）「，得到String（＃15868000）」。 –
