HAML rails form_for不調用POST方法

Question

我有一個表單名稱（反饋），我試圖提交它。

但是，它一直在調用GET HTTP方法。我已經嘗試爲form_for參數添加：method =>：post，但它仍然不起作用。我能知道它爲什麼不調用POST方法嗎？

耙路線：

 Prefix Verb URI Pattern    Controller#Action 
    feedbacks POST /feedback(.:format)  feedbacks#create 
new_feedback GET /feedback/new(.:format) feedbacks#new 
     root GET/      welcome#index 

FeedbacksController

class FeedbacksController < ApplicationController 

    def create 
    @feedback = Feedback.new(feedback_params) 
    @feedback.save 
    end 

    def new 
    @feedback = Feedback.new 
    end 

    private 
    def feedback_params 
     # params.require(:feedback).permit(: ) 
    end 

end

     .form-group 
     =feedback.submit("Submit", :class =>"btn-primary btn-lg btn-block") 

單擊「提交」後，我的輸出如下所示。

嘿傢伙嘗試了不同的解決方案，我可以通過堆棧找到，這對我有用。

HTML <form> tag causing Rails form to submit a GET instead of POST request

在評論中，其中一人解釋了原因：

@kcurtin：HTML，說自己窩所以瀏覽器只看到表單控件（即外形式）中， 默認方法屬性爲GET，默認操作爲當前的 URL。

Answer 2

不嵌套形成

%form.form-horizontal 
    =form_for(@feedback, :method => :post) do |feedback| 

應該

=form_for @feedback, :html => {:class => 'form-horizontal'} do |feedback| 

默認情況下，表單將提交表單與GET方法。但軌道form_for方法默認使用POST。您不需要明確將方法設置爲POST或將操作設置爲create。

通常情況下，表單部分呈現在new和edit中，並將根據對象的狀態（本例中爲@feedback）提交給創建和更新操作。在更新操作中，form_for方法會將提交的方法設置爲PUT（或PATCH）。明確地將其設置爲POST將會發生衝突。
