(Rails),如何将导航菜单中的 "Home" link 更改为徽标图像?

(Rails), How do I change "Home" link in my navigation menu to a logo-image?

我刚刚完成了模仿应用程序创建,就像我在在线课程中所做的那样。我想,我会更进一步,让我的应用程序看起来更漂亮。 我正在尝试将我的“主页”link 文本更改为图片。 当然,我以前在 HTML 做过,但在 Rails 没有做过。由于“link_to”方法,我有点困惑。我该怎么做,给出我当前的设置?

application.html.erb

<header>
      <div class="header-logo">
        <%= link_to("Home", "/") %>
      </div>
           ...

其中routes.rb是

get "/" => "home#top"

home.scss

感谢您的宝贵时间:)

我想这就是你想要的

<%= link_to "#{image_tag("name-of-img-here.png")}".html_safe, root_path %>

确保您的图像位于 app/assets/images/ 文件夹中,以便 link 正确。

您可能还需要添加一个 class,然后为其设置图片样式,使其看起来不错。

你可以试试<%= link_to image_tag('image_here'), '/' %>
