Rails 3.2.8 form_for提交按鈕正在使用「新」操作而不是「創建」操作

Question

填寫完值後，點擊f.submit只是刷新我的看法（new.html.erb）。我試圖將表單保存到我的數據庫並重定向到我的索引視圖。

我曾嘗試以下：

1. 刪除從posts_controller條件語句創建行動。
2. 將我的嵌套資源更改爲單數資源（職位）。
3. 通過我的表單中的URL散列傳遞路由選項。

我也在這些SO問題中遵循了相關的建議，但都沒有成功。

1. Rails Create Action Not Workinghttps://stackoverflow.com/editing-help

2. rails form_for never invokes the create controller action to use redirect_to

3. Rails form posting to /new instead of /create?

這裏是我的代碼：

Answer 2

您可以複製爲您的表單生成的HTML代碼嗎？此外，請嘗試以下操作：

form_for @post, :url => posts_path(), :method => :post 

並複製表單的HTML代碼。
