How to dynamically assign _data variable?












2















I'm using staticman to enable comments on my blog. It puts the comments in the _data folder. My folder structure then looks like this:



_data/
comments/
blog-post-1/
entry1542891129928.yml
...
blog-post-2/
entry1542891129928.yml
...
...


In my _layouts/post.html I want to access comments for a specific blog. This is the code that I expect to work to get to the comments:



{% assign comments = site.data.comments[page.slug] | sort %}


But when I run build, I get the following error:



Liquid Exception: Liquid error (line 39): Cannot sort a null object. in /_layouts/post.html


It seems to be something to do with page.slug because if I replace it with the string 'blog-post-1' it works.
