为什么不从视图中调用我的控制器 [英] Why isnt my controller being called from the view

问题描述

我正在尝试从我的erb html调用一个方法，该方法将在控制器中执行操作，但是未执行该操作。

Im trying to call a method from my erb html that will perform an action in the controller, however the action isn't being performed.

这是其中的代码html

Here's the code in the html

<td style="text-align: center">
  <%= button_to 'Vote', request_upvote_path(request.id), remote: true, method: :post, onclick: "upvote(#{request.id})", class: 'upvote', id:"voteButton#{request.id}" %>
</td> </tr>

这是控制器中的代码

def upvote
  puts 'upvote'
  @request = Request.find(params[:request_id])
  @request.increment!(:voteCount)
  @request.save
  render json: { voteCount: request.voteCount }
end  

这是路由文件

Rails.application.routes.draw do
  resources :requests do
    post 'upvote', to: 'requests#upvote'
    #get "requests/index"
  end
end

那里也有一些JS功能，但是工作正常。

Theres also some JS functionality in there, but that's working fine.

这里是JS

$("#ClickMe").attr("disabled", "disabled"); 



function upvote(id) {
    var count = document.getElementById("voteCount" + id).innerHTML;
    count = parseInt(count);
    count = count + 1;
    count = count.toString();
    document.getElementById("voteCount" + id).innerHTML = count;
    document.getElementById("voteButton" + id).disabled = true;
 }

推荐答案

这对很多人都有用反复试验的结果：

This worked for me after lots of trial and error:

<％= button_to'Vote'，request_upvote_path（request_id：request.id），remote：true，方法： ：post，onclick： upvote（＃{request.id}）％>
