如何在指定“方法：”时使用带有 link_to 的自定义 html

我正在尝试呈现以下 html：

<a href="<%= INSERT ARTICLE PATH WITH DELETE METHOD HERE %>" class="float-right action-button">
  <button type="button" class="btn btn-light">
    <%= image_tag("delete", size: "16x16") %>
  </button>
</a>

我试过这个没有成功：

<%= link_to(@article, method: :delete, class: "float-right action-button") do %>
  <button type="button" class="btn btn-light">
    <%= image_tag("delete", size: "16x16") %>
  </button>
<%= end %>

我收到以下错误：

SyntaxError in ArticlesController#index
C:/Sites/anais-coaching/app/views/articles/index.html.erb:34: syntax error, unexpected keyword_end ...eze;@output_buffer.append=( end );@output_buffer.safe_append... ... ^ C:/Sites/anais-coaching/app/views/articles/index.html.erb:43: syntax error, unexpected keyword_end, expecting ')' '.freeze; end ^ C:/Sites/anais-coaching/app/views/articles/index.html.erb:47: syntax error, unexpected keyword_ensure, expecting ')' C:/Sites/anais-coaching/app/views/articles/index.html.erb:49: syntax error, unexpected keyword_end, expecting ')'

我想我的问题是我不知道如何使用“link_to xxx do”。谢谢！

替换这个

<%= link_to @article, method: :delete,, data: {confirm:'Are you sure?' }, class: "float-right action-button") do %>
  <button type="button" class="btn btn-light">
    <%= image_tag("delete", size: "16x16") %>
  </button>
<%= end %>

有了这个

<%= link_to @article, method: :delete, data: {confirm:'Are you sure?' }, class: "float-right action-button" do %>
  <button type="button" class="btn btn-light">
    <%= image_tag("delete", size: "16x16") %>
  </button>
<% end %>

您不需要为 . 添加 <%= %> end。如果错误已解决，请告诉我。请检查link_to 的文档。
