如何將內聯css添加到rails link_to helper

Question

在5欄上，我的類別中有圖片。 我想將這些圖像用作背景圖像，但是當我設置樣式時，URL不會更改

<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>

我在這里做錯了什么

Answer 1

您需要插值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

您似乎在style屬性中使用rails插值的語法不正確，請嘗試以下操作，

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

Answer 3

這有效

<%= 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 %>
