This post should not be too difficult to read along with - and I will happily fix any problems you notice - but I do assume you know the basics of creating a blog with Jekyll. The code and templates were initially build on Jekyll 3.0.0.beta8.
Eric Tirado noticed that I broke the individual crafts project links -
again. So I fixed it for real. Just set the collection
something useful in
I ended up having several issues attributable to either collections under Jekyll 3.0 beta or Octopress 3. Decided to switch to Jekyll 2.5.3 and made a few adjustments to the collections template. Everything seems okay now.
So what the heck is a collection? From the Jekyll collections documentation:
Not everything is a post or a page. Maybe you want to document the various methods in your open source project, members of a team, or talks at a conference. Collections allow you to define a new type of document that behave like Pages or Posts do normally, but also have their own unique properties and namespace.
Collections could be useful when you have things you want to show on your site without necessarily being tied to the blog-centric structure of Posts or the simple content dump of a Page.
Who would that help, besides the slightly technical examples from the description?
- A writer could organize their stories into collections
- An artist could present their works as one or more collections
- A knitter could put their yarn projects in a collection.
- Anyone who takes pictures could use collections as photo galleries.
- Recipes, maybe?
- Music playlists!
- All the books I own, and the few I have actually read!
A blog post probably works for most of these use cases. Maybe fiddle a bit with categories and put a tag here and there, and your content is out there for anyone. Good enough.
“Good enough” isn’t good enough for every case, though. Occasionally you want to tune some of your content in a special way. You may find this is easier with collections than with blog posts.
There are also dedicated sites for all of these ideas, and those are good enough too. Some excel at the services they provide. They have concerns too. Now the visibility of your creations is tied to the fortunes and policies of whoever provides that service. Keeping that in a collection on your own site gives you a backup if the service goes away, at least.
I could use collections for my knitting and crochet projects. I have a couple of knitting blog posts here, and an account on Ravelry highlighting a handful of other WIPs[^1] and FOs[^2]. The blog posts work fine as blog posts, but I still want a separate way to organize those projects. The stuff on Ravelry can only be seen if you have an account with the service. That’s fine, but I have spent 2015 consolidating material I’ve created elsewhere onto my site. Ravelry is a reasonable next target for me.
First I need to add a
collections entry to my
file. This entry contains a list of all collections in the site, and metadata
for each collection. I want these collections displayed on the site, so I must
output metadata for the collection to
true. I also want to be sure
individual project pages are given consistent URLs, which has been an issue for
me bouncing between Jekyll 2.5.3 and Jekyll 3.0.0 beta. Setting
takes care of that issue.
collections: crafts: output: true permalink: /crafts/:path/
Next I create the folder to hold this collection. By default its name must match the collection name with an underscore prefix.
$ mkdir _crafts
Time to put something in the collection. I can use my recent garter stitch scarf post as a starting point, filling in the details of a new collection item from that post.
$ atom _crafts/garter-scarf-wrapped.markdown
