项目。图像未在Jekyll中显示

我在/_works/上有一堆投资组合帖子，前面的内容是这样的：

title: "Rock in Rio Lisbon 2018"
date: July, 2018
image: "/assets/images/work/rock-in-rio-lisbon-2018.jpg"
categories:
  - Intro
slides:
  - title: "Rock in Rio Lisbon 2018 Headliner Show for Bruno Mars, Katy Perry, Muse & The Killers"
    id: "O-rZ6IFnv9g"

override: true

{% assign works = site.works | reverse %}
{% for item in works limit:9 %}
<li class="{% cycle 'wide','','','','','','','','' %}">
<a href='{{ site.url }}{{ item.url }}'>


    {% if item.override %}
    {% for slide in item.slides limit:1 %}
        <img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="{{ site.url }}{{ slide.image }}" />
    {% endfor %}
    {% else %}
    {% for slide in item.slides limit:1 %}
        <img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="https://img.youtube.com/vi/{{ slide.id }}/sddefault.jpg" />
    {% endfor %}
    {% endif %}

    <div class='overlay'>
    <div class='thumb-info'>
        <h3>{{ item.title }}</h3>
        <p>{{ item.categories | sort |  join:" • " | escape }}</p>
        <p>{{ item.image }}</p>
    </div>
    </div>
</a>
</li>      
{% endfor %}

在主页上，我使用Slides.ID自动抓取YouTube视频的缩略图。如果前面的内容包括Override:true，它应该显示我定义的图像。以下是我所拥有的：

{% assign works = site.works | reverse %}
{% for item in works limit:9 %}
<li class="{% cycle 'wide','','','','','','','','' %}">
<a href='{{ site.url }}{{ item.url }}'>


    {% if item.override %}
    {% for item in item.slides limit:1 %}
        <img alt="A frame from a video of {{ item.title }}" loading="lazy" src="{{ site.url }}{{ item.image }}" />
    {% endfor %}
    {% else %}
    {% for item in item.slides limit:1 %}
        <img alt="A frame from a video of {{ item.title }}" loading="lazy" src="https://img.youtube.com/vi/{{ item.id }}/sddefault.jpg" />
    {% endfor %}
    {% endif %}

    <div class='overlay'>
    <div class='thumb-info'>
        <h3>{{ item.title }}</h3>
        <p>{{ item.categories | sort |  join:" • " | escape }}</p>
        <p>{{ item.image }}</p>
    </div>
    </div>
</a>
</li>      
{% endfor %}

{%assign works=site.works | reverse%}
{工程中项目的百分比限制：9%}


{%endfor%}

当Jekyll编译时，

{{item.image}

不起作用……但是，如果我将它与

{{item.title}}

交换，它确实起作用。知道为什么会发生这种情况吗？

您正在幻灯片中重用'item'变量，这会覆盖它。在幻灯片中循环时，将变量“item”重命名为“slide”，如下所示：

title: "Rock in Rio Lisbon 2018"
date: July, 2018
image: "/assets/images/work/rock-in-rio-lisbon-2018.jpg"
categories:
  - Intro
slides:
  - title: "Rock in Rio Lisbon 2018 Headliner Show for Bruno Mars, Katy Perry, Muse & The Killers"
    id: "O-rZ6IFnv9g"

override: true

{% assign works = site.works | reverse %}
{% for item in works limit:9 %}
<li class="{% cycle 'wide','','','','','','','','' %}">
<a href='{{ site.url }}{{ item.url }}'>


    {% if item.override %}
    {% for slide in item.slides limit:1 %}
        <img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="{{ site.url }}{{ slide.image }}" />
    {% endfor %}
    {% else %}
    {% for slide in item.slides limit:1 %}
        <img alt="A frame from a video of {{ slide.title }}" loading="lazy" src="https://img.youtube.com/vi/{{ slide.id }}/sddefault.jpg" />
    {% endfor %}
    {% endif %}

    <div class='overlay'>
    <div class='thumb-info'>
        <h3>{{ item.title }}</h3>
        <p>{{ item.categories | sort |  join:" • " | escape }}</p>
        <p>{{ item.image }}</p>
    </div>
    </div>
</a>
</li>      
{% endfor %}

{%assign works=site.works | reverse%}
{工程中项目的百分比限制：9%}


{%endfor%}
