jekyll: combine limit and where and reverse -
using jekyll i'd to:
- iterate through pages
- where page.path not current path
- where page.categories contains "featured"
- reverse them(most recent first)
- limit 3
i'm having problems when getting filters together
{% assign posts = site.posts | reverse %} {% post in posts limit:3 %} {% if post.categories contains 'featured' , post.path != page.path %} {% include card.html post=post %} {% endif %} {% endfor %} right limit not working because inner if prevent few items being rendered.
assign 0 counter variable before entering loop. don't set limit on loop, instead set condition on counter being below limit, , increment counter using liquid's plus filter every time meet criteria , output card.
{% assign posts = site.posts | reverse %} {% assign counter = 0 %} {% post in posts %} {% if counter < 3 , post.categories contains 'featured' , post.path != page.path %} {% include card.html post=post %} {% assign counter = counter | plus: 1 %} {% endif %} {% endfor %} a more complex example
i'm basing of on looping use myself. condition little more complex: check shared tag current page. i've included further example below.
{% assign counter = 0 %} {% post in site.posts %} {% if counter < 4 %} {% if post.url != page.url %} {% assign isvalid = false %} {% page_tag in page.tags %} {% post_tag in post.tags %} {% if post_tag == page_tag %} {% assign isvalid = true %} {% endif %} {% endfor %} {% endfor %} {% if isvalid %} {% include article_card.html %} {% assign counter = counter | plus: 1 %} {% endif %} {% endif %} {% endif %} {% endfor %} why where fails
although liquid has where filter, can exact comparisons, have reinvent wheel in order achieve where-like scenario more complex conditions. make lot of looping through site.posts, jekyll being preprocessor means penalty of using inefficient improvised where-type looping compile-time concern, not runtime one. so, mitigate cost as possible, opt having counter condition first jekyll calculates.
