如何將url中的參數傳遞到Rails中的另一個資源？

Question

我正在開發一種工作板，其中有一個名為“ jobdetails”的“頁面”，其中包含工作詳細信息（“ jobdetails”顯示職位資源），帶有“應用”按鈕的工作應重定向至“求職者”“頁面”，求職者可以在該頁面上載他的簡歷（尚未實現）並保存open_id。

我嘗試了許多方法，但仍然無法正常工作。

我說過我想用url傳遞參數，但是我可以用其他方式打開，例如模型或控制器。

謝謝。

編輯：我能夠保存一條記錄，但opening_id保持空白...

Answer 1

在你看來改變opening到opening_id ：

<%= link_to "Apply now", new_jobapplication_path(opening_id: @jobdetail.id) %>

在您的new操作中，使用opening_id實例化：

def new
  @jobapplication = Jobapplication.new(opening_id: params[:opening_id])
end
