Question

am on rails 5，我的类别有图片。我想将这些图像用作背景图像，但是当我在样式中设置时，网址不会改变

<div class="grid-category">
    <% @servicescategories.each do |category| %>

    <%= link_to servicecategories_path(slug: category.slug ), :style=>'background-image: asset-data-url("category.category_image");',  class: "category-item" do %>



        <h3> <%= category.name %></h3>


        <% end %>
    <% end %>
  </div>

我在这里做错了什么

Answer 1

您需要插入category.category_image

的值

<%= link_to servicecategories_path(slug: category.slug ),  
            class: "category-item" do %>

  <div style="background-image: url(<%= asset_path('category.category_image') %>)">
    <h3> <%= category.name %></h3>
  </div> 

<% end %>

Answer 2

您似乎使用不正确的语法在style属性中使用rails插值，试试这个，

 <%= link_to servicecategories_path(slug: category.slug ),
 :style=>"background-image: <%= asset-data-url(category.category_image) %>",
   class: "category-item" do %>

Answer 3

这是有效的

<%= link_to servicecategories_path(slug: category.slug ),  
            class: "category-item" do %>

  <div style="background-image: <%= asset_path('category.category_image') %>">
    <h3> <%= category.name %></h3>
  </div> 

<% end %>
