You need to have that image file alongside _index.md (in the same bundle) in order for it to be a Page Resource. Is it the case?
If not: The resources param in the Front Matter simply allow to assign meta data to a Page Resource, it does not allow to assign a Page Resource to a page. Only placing the file in the bundle can do that.
Correct. That gets ambigous pretty fast. I guess we could probably support it, but this limitation makes it much simpler – we don’t have to traverse down the file tree to see if there is a nested section somewhere down there …
I would actually suggest you keep it this way. It’s already hard enough for me to distinguish between taxonomy and section, making them behave more like page bundles would just make it a bigger mess in my head.
Just to close the loop of this story. After understanding the difference between taxonomies and sections, I went back to my code and was able to rewrite a bunch of nasty hacks that I had for organising the content into “stories”.
I must have done something wrong in the instagram/single.html file because it takes 4 minutes to render, but that is a problem for another time. Thanks again guys!
