Access to Page Resources (simple)

[vin]

Hi guys,

I’m a beginner with Hugo and I really like it. I’ve got a probably simple question, I looked for an answer way too long and I cannot find what I’m doing wrong.

I’ve got an image (boat.jpg) together with an index.md file in the same content directory. Inside the single.html template I want to access the image url in a single line. Like:

<img src="{{ (.Resources.GetMatch "boat.jpg").RelPermalink }}" />

But this gives the following error:

render of "page" failed: "C:\c\sites\bb\layouts\_default\single.html:24:39": execute of template failed: template: _default/single.html:24:39: executing "main" at <"boat.jpg">: nil pointer evaluating resource.Resource.RelPermalink

While writing it like this does work fine:
{{ with .Resources.GetMatch “boat.jpg” }}<img src="{{ .RelPermalink }}">{{ end }}

What is the difference, and can I make the first method working?

Thnx in advance

{{ with .Resources.GetMatch “boat.jpg” }}<img src="{{ .RelPermalink }}">{{ end }}

The above works because the code block is escaped if boat.jpg is not found.

You encounter the error:

render of "page" failed: "C:\c\sites\bb\layouts\_default\single.html:24:39": execute of template failed: template: _default/single.html:24:39: executing "main" at <"boat.jpg">: nil pointer evaluating resource.Resource.RelPermalink

Because not every Page rendered by the template _default/single.html has a boat.jpg as a resource.

You need to performs checks in a Hugo project’s templates, with is the function to use for such checks.

Wow, you’re fast!

When you explain it like that it makes sense

I’ll use the second method and stop trying the first haha

Thanks for your answer!
