Question

我有以下错误：

＆＃34;致敬＆＃39;成绩＆＃39;反馈。＆＃34;

链接是rails控制台的屏幕，发送的参数是：

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

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

我不知道出了什么问题！

Answer 1

您应该有两件事来创建成绩单条目以及您的观点中的反馈条目：

C

None (CMAKE_C_FLAGS or CMAKE_CXX_FLAGS used) Debug (CMAKE_C_FLAGS_DEBUG or CMAKE_CXX_FLAGS_DEBUG) Release (CMAKE_C_FLAGS_RELEASE or CMAKE_CXX_FLAGS_RELEASE) RelWithDebInfo (CMAKE_C_FLAGS_RELWITHDEBINFO or CMAKE_CXX_FLAGS_RELWITHDEBINFO MinSizeRel (CMAKE_C_FLAGS_MINSIZEREL or CMAKE_CXX_FLAGS_MINSIZEREL)。
表单中的名称应为belongs_to :gradework，而不是Feedback

Answer 2

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]") %>

您的表单正在发送不在您的模型中的gradework属性（Feedback），因此您需要发送gradework_id，所以请尝试将以上行转换为此：< / p>

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

这会将gradework_id作为参数发送，并在select中选择任何值。

未知属性＆＃39; gradework＆＃39;反馈
