我可以使用 Rails link_to 来制作 POST 而不是 button_to 吗? [英] Can I use Rails link_to to make a POST instead of a button_to?

问题描述

我正在使用 inline_svg gem 为我的图标渲染 SVG.我的视图代码如下所示:

<%= link_to inline_svg(listing.favorite_icon, class: "svg"), favorite_listing_path(id: listing.id), method: :post %>

我有一个心形图标，当用户点击它时，应该对 Rails favorite 路由进行 POST.我在 Postman 中对此进行了测试，并且在我的视野之外它确实可以正常工作.但是，在我看来，单击收藏夹会生成 GET.

我知道我可以使用 button_to 而不是 link_to 然后 POST 就会发生..但是...button_to 无法正确呈现我的 SVG(请参阅附图).

所以我可以选择以下两种方式之一...有人可以帮我将 link_to 设置为 POST 吗?或者有人可以告诉我为什么我的 SVG 无法使用 button_to 正确呈现?

使用link_to:

使用button_to:

更新:以下是我尝试过的一些事情...单击仍然会导致 GET.另外，如果这有什么不同的话，我正在使用 Rails 4.2.

<%= link_to "hi", controller: "listings", action: "favorite", id: listing.id, method: :post %><%= link_to(inline_svg(listing.favorite_icon, class: "svg"), controller: "listings", action: "favorite", id: listing.id, method: :post) %>

<%= link_to(favorite_listing_path(id: listing.id), method: :post) do %><div class="icon"><%= inline_svg(listing.favorite_icon, class: "svg") %>

<%结束%>

解决方案

我想通了.当我开始 Rails 项目时，我去掉了 Rails-Jquery.我没有意识到 { method: POST } 使用这个.

I am using the inline_svg gem to render SVGs for my icons. My view code looks like this:

<div class="icon">
  <%= link_to inline_svg(listing.favorite_icon, class: "svg"), favorite_listing_path(id: listing.id), method: :post  %>
</div>

I have a heart icon that, when the user clicks it, a POST should be made to the Rails favorite route. I tested this in Postman and it does correctly work outside of my view. But, inside of my view, clicking favorite generates a GET.

I know I can use button_to instead of link_to and the POST will then happen..BUT...button_to doesn't render my SVG properly (see attached pics).

So I can go one of two ways...can someone help me get my link_to to POST? Or can someone give me a clue as to why my SVG doesn't render correctly with button_to?

With link_to:

With button_to:

UPDATE: Here are some things I have tried...clicking still results in a GET. Also, I'm on Rails 4.2 if that makes a difference at all.

<%= link_to "hi", controller: "listings", action: "favorite", id: listing.id, method: :post  %>

<%= link_to(inline_svg(listing.favorite_icon, class: "svg"), controller: "listings", action: "favorite", id: listing.id, method: :post)  %>

<%= link_to(favorite_listing_path(id: listing.id), method: :post)  do %>
  <div class="icon">
    <%= inline_svg(listing.favorite_icon, class: "svg") %>
  </div>
<% end %>

解决方案

I figured this out. When I started the Rails project, I stripped out Rails-Jquery. I didn't realize the { method: POST } uses this.
