Why is something like this not working ?
i try to filter all posts from this year
<div class="tiles">
{% for post in site.categories.articles %}
{% capture pubyear %} {{ post.date | date: "%Y" }} {% endcapture %}
{% if pubyear == "2014" %}
{% include post-grid.html %}
{% endif %}
{% endfor %}
</div><!-- /.tiles -->
The problem is that it is capturing the output with some spaces in it, so it fails the if condition, remove those spaces and it should work
<div class="tiles">
{% for post in site.categories.articles %}
{% capture pubyear %}{{ post.date | date: "%Y" }}{% endcapture %}
{% if pubyear == "2014" %}
{% include post-grid.html %}
{% endif %}
{% endfor %}
</div>
Capturing the pubyear is vaild but you can also assign pubyear with no spaces.
{% assign pubyear = post.date | date: "%Y" %}

I have several blog posts that fall under one umbrella blog post. For example, I have several posts about SQL Zoo tutorials, but I want to be able to link them all up to one "umbrella" post so that I only have one SQL Zoo post on the index page of my blog. I got this idea from: https://codeasashu.github.io/implement-series-post-jekyll-part-2/ and tried to follow the instructions, but now my series post does not show up on my index page. I have the following code in a file called post-series.html located in my _includes folder:
{% assign seriesarray = '|' | split : '|' %}
{% assign seriestitle = '' %}
{% assign serieslabel = '' %}
{% assign sortedposts = (site.posts | sort: 'date') %}
{% for post in sortedposts %}
{% if post.series and page.series_slug != nil and post.series == page.series_slug %}
{% capture postitem %} <li> {{ post.title }} </li> {% endcapture %}
{% assign seriesarray = seriesarray | push: postitem %}
{% assign seriestitle = 'Posts in this series' %}
{% assign serieslabel = 'Series Post' %}
{% elsif post.series != nil and page.series != nil and page.series == post.series %}
{% assign pageurl = page.url | split:'/' | last %}
{% assign posturl = post.url | split:'/' | last %}
{% if pageurl != posturl %}
{% capture postitem %} <li> {{ post.title }} </li> {% endcapture %}
{% else %}
{% capture postitem %} <li> {{ post.title }} </li> {% endcapture %}
{% endif %}
{% assign seriesarray = seriesarray | push: postitem %}
{% endif %}
{% if post.series_slug != nil and page.series != nil and page.series == post.series_slug %}
{% capture series_title %} {{ post.title }} {% endcapture %}
{% assign seriestitle = 'This posts is part of series - ' | append: series_title %}

In your index.html, {% if post.series == nil %} simply bares posts containing a series: someserie front matter variable to be printed.
For the second problem (note that on SO, you are supposed to ask one question at a time) :
Umbrella post always have series_slug: "My serie slug" in front
matter.
Serie's posts always have series: "My serie slug" in front
matter, and this must be strictly equal to umbrella page series_slug. (eg : you have a post with published: false and series: "SQL Zoology" that will not appear in SQL Zoo serie if you publish it.)
In _layouts/post.html remove {% include series.html %}.
In _includes/post-series.html replace all your code by the following :
{% comment %} #### On an umbrella page {% endcomment %}
{% if page.series_slug != nil %}
{% assign key = page.series_slug %}
{% assign title = page.title %}
{% assign url = page.url %}
{% assign sentence = "All posts in this serie :" %}
{% endif %}
{% comment %} #### On a serie page {% endcomment %}
{% if page.series != nil %}
{% assign key = page.series %}
{% assign umbrella_page = site.posts | where: 'series_slug', key | first %}
{% assign title = umbrella_page.title %}
{% assign url = umbrella_page.url %}
{% assign series_posts = site.posts | where: "series", key %}
{% for post in series_posts %}
{% if post.url == page.url %}
{% assign idx = forloop.index %}
{% endif %}
{% endfor %}
{% capture sentence %}
This article is <strong>Part {{ idx }}</strong> in a <strong>{{ series_posts.size }}-Part</strong> in {{ title }} serie
{% endcapture %}
{% endif %}
{% if page.series_slug != nil or page.series != nil %}
{% assign series_posts = site.posts | where: "series", key %}
<hr />
<div class="panel">
<div class="panel-body">
{% if page.series_slug != nil %}
{% assign key = page.series_slug %}
{% assign title = page.title %}
{% assign url = page.url %}
{% endif %}
<h4>{{ sentence }}</h4>
<ul id="post-series-list">
{% for post in series_posts %}
<li>
{% if page.url == post.url %}
This post : {{ post.title }} - part {{ forloop.index }}
{% else %}
{{ post.title }} - part {{ forloop.index }}
{% endif %}
</li>
{% endfor %}
</ul>
</div>
</div>
{% endif %}
The problem you are facing
You forgot to add the series and series_slug YML variables. That is why it is not working in your case. You seem to not fully understand how the code works, probably due to the complexity of the solution. Therefore, I added another (much simpler) solution, that might fit your needs equally well.
A better/simpler solution
Simply add a YML variable called group: groupname to each post you want in a group. Do NOT skip any of the posts during pagination. Next, list the posts with the same group on the footer of each post (in your page/post layout) with the code below. Finally, add 'part 1', 'part 2', etc. to the post names in the series.
{% if post.group != nil %}
<ul>
{% for post in site.posts %}
{% if post.group == page.group %}
<li>{{ post.title }}</li>
{% endif %}
{% endfor %}
</ul>
{% endif %}
PS. If you really want to skip some posts in the pagination, I would create an universal solution. Add a skip_pagination boolean to the Front Matter (YML) and see if it is true in the pagination loop. This enables you to skip any post in the paginator.
I'm trying to create a page in my Jekyll site that will display a custom variable and list the posts that contain that custom variable.
I have created a movie review blog using a template Thiago Rossener created:
Thiago's Template: https://github.com/thiagorossener/jekflix-template
My Site: https://www.howdareyoureview.com/
in each post, I have defined custom variables in the YAML front matter that relate to the movie's details (i.e actor, director score, etc.)
for example:
---
layout: post
title: "Baby Driver"
image: 'https://res.cloudinary.com/how-dare-you-review/image/upload/c_fill,h_399,w_760/v1529865791/baby-driver.png'
tags:
- action
score: 72
director: Edgar Wright
written-by: Edgar Wright
staring:
- Ansel Elgort
- Lily James
- Eiza González
- Jon Hamm
- Jamie Foxx
---
I want to create pages exactly like the tags page that already exists in this template:
https://www.howdareyoureview.com/tags/
except I would want to sort by director, starring, etc. instead of by tags.
the tags page is created using the following code in a tags.html file:
---
layout: minimal
title: "#Tags"
permalink: /tags/index.html
description: "Procure por sua #tag favorita."
---
<div class="tags">
{% assign tags_list = site.tags %}
{% if tags_list.first[0] == null %}
{% for tag in tags_list %}
{{ tag }}
{% endfor %}
{% else %}
{% for tag in tags_list %}
{{ tag[0] }}
{% endfor %}
{% endif %}
{% assign tags_list = nil %}
</div>
{% for tag in site.tags %}
<div class="tag-wrapper">
<span class="tag-title" id="{{ tag[0] | slugify }}">{{ tag[0] }}</span>
<ul class="post-list">
{% assign pages_list = tag[1] %}
{% for post in pages_list reversed %}
{% if post.title != null %}
{% if group == null or group == post.group %}
<li>{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></li>
{% endif %}
{% endif %}
{% endfor %}
{% assign pages_list = nil %}
{% assign group = nil %}
</ul>
</span>
</div>
{% endfor %}
To achieve this for the custom variables I created I tried replacing "tag/tags" with director and saving the file out into to root directory as "directors.html" but the page is blank.
---
layout: minimal
title: "#Directors"
permalink: /directors/index.html
description: "Procure por sua director favorita."
---
<div class="directors">
{% assign directors_list = site.director %}
{% if directors_list.first[0] == null %}
{% for director in directors_list %}
{{ director }}
{% endfor %}
{% else %}
{% for director in directors_list %}
{{ director[0] }}
{% endfor %}
{% endif %}
{% assign directors_list = nil %}
</div>
{% for director in site.director %}
<div class="director-wrapper">
<span class="director-title" id="{{ tag[0] | slugify }}">{{ director[0] }}</span>
<ul class="post-list">
{% assign pages_list = director[1] %}
{% for post in pages_list reversed %}
{% if post.title != null %}
{% if group == null or group == post.group %}
<li>{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></li>
{% endif %}
{% endif %}
{% endfor %}
{% assign pages_list = nil %}
{% assign group = nil %}
</ul>
</span>
</div>
{% endfor %}
Since the code and the concept is exactly the same as the way tags are populated - I cannot understand why this doesn't work - I'm hoping someone can assist!
Here is my entire directory for reference:
https://github.com/howdareyoureview/howdareyoureview.github.io
Tags page uses site.tags, which is an array of site.posts grouped by tag, created by Jekyll at generation time.
You're trying to replicate by targeting site.directors but this expected array doesn't exist. But, you can use the group_by filter to achieve your goal.
<div class="directors">
{% assign directors = site.posts | group_by: 'director' | sort: "name" %}
{% for director in directors %}
{% if director.name == "" %}
{% assign name = "Anonymous" %}
{% else %}
{% assign name = director.name %}
{% endif %}
{{ name }}
{% endfor %}
</div>
{% for director in directors %}
<div class="director-wrapper">
{% if director.name == "" %}
{% assign name = "Anonymous" %}
{% else %}
{% assign name = director.name %}
{% endif %}
<span class="director-title" id="{{ name | slugify }}">{{ name | debug }}</span>
<ul class="post-list">
{% assign pages_list = director.items %}
{% for post in pages_list reversed %}
<li>{{ post.title }}<span class="entry-date"><time datetime="{{ post.date | date_to_xmlschema }}" itemprop="datePublished">{{ post.date | date: "%m/%d/%Y" }}</time></li>
{% endfor %}
</ul>
</span>
</div>
{% endfor %}
Tip : You can use the inspect filter to debug your vars. {{ myvar | inspect }}
How can I use for example {{ post.date | date: "%H:%M %p - %-d %b %y" }} in code highlighting?
The only way I have found so far is using {% raw %}{{ post.date | date: "%H:%M %p - %-d %b %y" }}{% endraw %}. However, then it shows the code snippet as unformatted text rather than with proper inline code highlighting.
If I use
`{{ post.date | date: "%H:%M %p - %-d %b %y" }}`
then the code is rendered instead of shown as code.
{% highlight html %}
{% raw %}
{% include google_analytics.html %}
{% endraw %}
{% endhighlight %}
That is how I do it.
Check it out live:
http://www.madhur.co.in/blog/2013/11/05/makingmostdatadirectory.html
{% highlight html %}
{% raw %}
{% for project in site.data.projects %}
{% if project.publish == true %}
<strong>{{ project.project }}</strong>
<span class="tag-project">{{ project.category }}</span>
{{ project.description }}
<hr/>
{% endif %}
{% endfor %}
</div>
{% endraw %}
{% endhighlight %}
you can do that easily by combining {% highlight %} and {% raw %}
for example
{% highlight ruby %}
{% raw %}
---
limit: 100
---
{% for post in site.posts limit: page.limit %}
{
"title": "{{ post.title }}",
"date" : "{{ post.date | date: "%B %d, %Y" }}",
"excerpt" : "{{ post.excerpt }}",
{% if post.categories %} "categories" : [
{% for category in post.categories %} "{{ category }}"
{% if forloop.last %}{% else %},{% endif %}
{% endfor %}
],
{% endif %}
{% if post.categories == nil %} "categories" : [], {% endif %}
"url": "{{ post.url }}",
{% if post.tags %} "tags" : [
{% for tag in post.tags %} "{{ tag }}"
{% if forloop.last %}{% else %},{% endif %}
{% endfor %}
]
{% endif %}
{% if post.tags == nil %} "tags" : [] {% endif %}
}
{% unless forloop.last %},{% endunless %}
{% endfor %}
{% endraw %}
{% endhighlight %}
I'm rewriting my blog to use Jekyll. Jekyll uses the Liquid templating language so it makes it a little more difficult to learn how to customize.
I'd like to group my list of blog posts by year. How would I write the Liquid code to be able to do this?
{% for post in site.posts %}
<li><!-- display post year here (but only once, per year) --></li>
<li>
{{ post.title }}
</li>
{% endfor %}
It can be done with much, much less Liquid code than in the existing answers:
{% for post in site.posts %}
{% assign currentdate = post.date | date: "%Y" %}
{% if currentdate != date %}
<li id="y{{currentdate}}">{{ currentdate }}</li>
{% assign date = currentdate %}
{% endif %}
<li>{{ post.title }}</li>
{% endfor %}
This will return exactly the HTML specified in your question:
<li id="y2013">2013</li>
<li>foo</li>
<li id="y2012">2012</li>
<li>bar</li>
<li>baz</li>
However, this is not the optimal solution, because the year numbers are "only" list items as well.
It's not much more Liquid code to put the year into a headline and to begin a new <ul> for each year's posts:
{% for post in site.posts %}
{% assign currentdate = post.date | date: "%Y" %}
{% if currentdate != date %}
{% unless forloop.first %}</ul>{% endunless %}
<h1 id="y{{post.date | date: "%Y"}}">{{ currentdate }}</h1>
<ul>
{% assign date = currentdate %}
{% endif %}
<li>{{ post.title }}</li>
{% if forloop.last %}</ul>{% endif %}
{% endfor %}
The generated HTML:
<h1 id="y2013">2013</h1>
<ul>
<li>foo</li>
</ul>
<h1 id="y2012">2012</h1>
<ul>
<li>bar</li>
<li>baz</li>
</ul>
You can also group by month and year instead (so that the headlines are February 2012, January 2012 and so on).
To do this, you just need to replace date: "%Y" (in the second line of both above examples) by date: "%B %Y".
(%B is the full month name, see the documentation)
These previous solutions are fantastic but luckily in late 2016, Jekyll added a group_by_exp filter that can do this much more cleanly.
{% assign postsByYear =
site.posts | group_by_exp:"post", "post.date | date: '%Y'" %}
{% for year in postsByYear %}
<h1>{{ year.name }}</h1>
<ul>
{% for post in year.items %}
<li>{{ post.title }}-{{ post.date }}</li>
{% endfor %}
</ul>
{% endfor %}
Documentation can be found on the Jekyll Templates page.
If you want to break it down by year, here's the code:
{% for post in site.posts %}
{% capture this_year %}{{ post.date | date: "%Y" }}{% endcapture %}
{% capture next_year %}{{ post.previous.date | date: "%Y" }}{% endcapture %}
{% if forloop.first %}
<h2 id="{{ this_year }}-ref">{{this_year}}</h2>
<ul>
{% endif %}
<li>{{ post.title }}</li>
{% if forloop.last %}
</ul>
{% else %}
{% if this_year != next_year %}
</ul>
<h2 id="{{ next_year }}-ref">{{next_year}}</h2>
<ul>
{% endif %}
{% endif %}
{% endfor %}
If you want to break it down to year and months it can be achieved like this:
{% for post in site.posts %}
{% capture this_year %}{{ post.date | date: "%Y" }}{% endcapture %}
{% capture this_month %}{{ post.date | date: "%B" }}{% endcapture %}
{% capture next_year %}{{ post.previous.date | date: "%Y" }}{% endcapture %}
{% capture next_month %}{{ post.previous.date | date: "%B" }}{% endcapture %}
{% if forloop.first %}
<h2 id="{{ this_year }}-ref">{{this_year}}</h2>
<h3 id="{{ this_year }}-{{ this_month }}-ref">{{ this_month }}</h3>
<ul>
{% endif %}
<li>{{ post.title }}</li>
{% if forloop.last %}
</ul>
{% else %}
{% if this_year != next_year %}
</ul>
<h2 id="{{ next_year }}-ref">{{next_year}}</h2>
<h3 id="{{ next_year }}-{{ next_month }}-ref">{{ next_month }}</h3>
<ul>
{% else %}
{% if this_month != next_month %}
</ul>
<h3 id="{{ this_year }}-{{ next_month }}-ref">{{ next_month }}</h3>
<ul>
{% endif %}
{% endif %}
{% endif %}
{% endfor %}
It is only a matter of where do you make the cut on the loop.
Some solutions above are very complex but then as #Trevor pointed out that we can levarage Jekyll's group_by_exp filter. Also I liked the solution but what I needed was grouped by Year and then inside that list grouped by Month. So, I tweaked it a little bit.
{% assign postsByYear = site.posts | group_by_exp:"post", "post.date | date: '%Y'" %}
{% for year in postsByYear %}
<h1>{{ year.name }}</h1>
{% assign postsByMonth = year.items | group_by_exp:"post", "post.date | date: '%B'" %}
{% for month in postsByMonth %}
<h2>{{ month.name }}</h2>
<ul>
{% for post in month.items %}
<li>{{ post.title }}-{{ post.date }}</li>
{% endfor %}
</ul>
{% endfor %}
{% endfor %}
Variation of Ankit R Gadiya's answer. The inner for loop was displaying the html code. I needed to de-indent it to get it to properly render the markup. I also added the post's excerpt:
{% assign postsByYear = site.posts | group_by_exp:"post", "post.date | date: '%Y'" %}
{% for year in postsByYear %}
<h1>{{ year.name }}</h1>
{% assign postsByMonth = year.items | group_by_exp:"post", "post.date | date: '%B'" %}
{% for month in postsByMonth %}
<h2>{{ month.name }}</h2>
<ul>
{% for post in month.items %}
<li>
{{ post.title }}
<br>{{ post.excerpt }}
</li>
{% endfor %}
</ul>
{% endfor %}
{% endfor %}
Example:
Try:
{% for post in site.posts %}
{% capture this_year %}{{ post.date | date: "%Y" }}{% endcapture %}
{% if forloop.first %}
<h2 id="{{ this_year }}-ref">{{this_year}}</h2>
<ul class="posts">
{% else %}
{% if this_year != last_year %}
</ul>
<h2 id="{{ this_year }}-ref">{{this_year}}</h2>
<ul class="posts">
{% endif %}
{% endif %}
<li>
<span class="post-date">{{ post.date | date_to_string }} »</span>
{{ post.title }}
</li>
{% if forloop.last %}
</ul>
{% endif %}
{% capture last_year %}{{ this_year }}{% endcapture %}
{% endfor %}
<ul>
{% for post in site.posts %}
{% assign year = post.date | date: "%Y" %}
{% if year != prev_year %}
<h3>{{year}}</h3>
{% endif %}
<li>
<span>{{ post.date | date: "%B %e, %Y" }}</span>
{{ post.title }}
</li>
{% assign prev_year = year %}
{% endfor %}
</ul>
Did not much like the other answer so here's an alternative for you. Basic logic: Display year/month only if it "new":
{% assign var currentYear = 0 %}
{% assign var currentMonth = 0 %}
{% for post in site.posts %}
{% capture year %}{{ post.date | date: "%Y" }}{% endcapture %}
{% capture month %}{{ post.date | date: "%B" }}{% endcapture %}
{% if currentYear != year %}
<div>
<h2>{{ year }}</h2>
</div>
{% assign var currentYear = year %}
{% endif %}
{% if currentMonth != month %}
<div>
<h3>{{ month }}</h3>
</div>
{% assign var currentMonth = month %}
{% endif %}
<p>{{ post.title }}</p>
{% endfor %}
