Website has multiple backgrounds. To make navigation more intuitive additional class (in this example in CSS will target .active.projects) needs to be added to one of the nav items (in this case, /projects/).
My take which does not work is the 2nd elsif.
/ is used for homepage.
{% assign links = site.data.navigation %}
{% for link in links %}
{% assign class = nil %}
{% if page.url == link.url %}
{% assign class = 'active' %}
{% elsif link.url != '/' and page.url contains link.url %}
{% assign class = 'active' %}
{% elsif link.url == '/projects/' and page.url contains link.url %}
{% assign class = 'active projects' %}
{% endif %}
<li class="{{ class }}">
{{ link.name }}
</li>
{% endfor %}
navigation.yml
- name: Home
url: /
- name: Blog
url: /blog/
- name: Projects
url: /projects/
- name: About
url: /about/
How to specify active state for exceptional nav item?
Change the order:
{% assign links = site.data.navigation %}
{% for link in links %}
{% assign class = nil %}
{% if page.url == link.url and link.url != '/projects/' %}
{% assign class = 'active' %}
{% elsif link.url == '/projects/' and page.url contains link.url %}
{% assign class = 'active projects' %}
{% elsif link.url != '/' and page.url contains link.url %}
{% assign class = 'active' %}
{% endif %}
{% endfor %}

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 %}
{% assign serieslabel = 'This posts is part of series - ' | append: series_title %}
{% endif %}
{% endfor %}
{% capture serieslayout %}
{% if seriesarray.size > 0 %}
<hr />
<div class="panel">
<div class="panel-body">
<h4> {{ seriestitle }} </h4>
<ul id="post-series-list">
{% endif %}
{% for post in seriesarray %} {{ post }} {% endfor %}
{% if seriesarray.size > 0 %} </ul> </div> </div> {% endif %}
{% endcapture %}
and the following code from my index.html file in the root of my directory:

<div id="home">

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 have the following code working in a Django HTML template. However, it’s quite repetitive. How can this code be simplified?
It translates to, "If you're not staff, you get to see nav.html. If you are staff, you only get to see nav.html if you're on these 4 pages."
{% if not request.user.is_staff %}
{% include ‘nav.html’ %}
{% else %}
{% if request.get_full_path == ‘/one/’ %}
{% include ‘nav.html’ %}
{% if request.get_full_path == ‘/two/’ %}
{% include ‘nav.html’ %}
{% if request.get_full_path == ‘/three/’ %}
{% include ‘nav.html’ %}
{% if request.get_full_path == ‘/four/’ %}
{% include ‘nav.html’ %}
{% endif %}
{% endif %}
From your view, you can send a list containing the paths for which to show nav.html. Something like,
allowed_paths = ['/one/', '/two/', '/three/', '/fourth/']
In your template, you can simply do,
{% if not request.user.is_staff or request.get_full_path in allowed_paths %}
{% include 'nav.html' %}
{% endif %}
I have a template in django that shows a link if a user has group name different than patient.
My code is:
{% if user.is_authenticated %}
{% for group in user.groups.all %}
{% if group.name != 'Patient' %}
<li {% if request.get_full_path == modules_url %} class="active" {% else%} class="inactive"{% endif %}>
<b style="color:#ff9904;">Modules</b>
</li>
{% endif %}
{% endfor %}
{% endif %}
In case a user is a member of four different groups, the link Modules is shown 4 times in the template.
Is there any way to show it only once?
I think by handle using templatetags should easier.
from django import template
from django.contrib.auth.models import Group
register = template.Library()
#register.filter(name='has_group')
def has_group(user, group_name):
"""
{% if request.user|has_group:'grouName' %}
{# do_stuff #}
{% endif %}
return Boolean (True/False)
"""
group = Group.objects.get(name=group_name)
return group in user.groups.all()
Basicly you can also do with this to get first group:
{% if user.groups.all.0 == 'Patient' %}
...
{% endif %}
I found the solution thanks to here. I used the forloop.counter variable.
{% if user.is_authenticated %}
{% for group in user.groups.all %}
{% if group.name != 'Patient' %}
{% if forloop.counter < 2 %}
<li {% if request.get_full_path == modules_url %} class="active" {% else%} class="inactive"{% endif %}>
<b style="color:#ff9904;">Modules</b>
</li>
{% endif %}
{% endif %}
{% endfor %}
{% endif %}
I am attempting to rebuild a sidebar widget which shows my categories used in Jekyll. It works fine as it is now. I want to change the liquid templating to exclude one specific category link from being shown in this widget.
{% assign cat_list = site.categories %}
{% if cat_list.first[0] == null %}
{% for category in cat_list %}
<li>{{ category }} <span class="cat-count">{{ cat_list[category].size }}</span></li>
{% endfor %}
{% else %}
{% for category in cat_list %}
<li>{{ category[0] }} <span class="cat-count">{{ category[1].size }}</span></li>
{% endfor %}
{% endif %}
{% assign cat_list = nil %}
I think what I want is something like
{% for category in cat_list **UNLESS category = 'CATEGORY'** %}
But that did not work. I'm kinda stuck, is this possible?
Thank You.
Not displayed categories array :
{% assign noDisplay = "one,two,three" | split: "," %} => ["one", "two", "three"]
The test :
{% unless noDisplay contains category[0] %}
{{ category[0] }}...
{% endunless %}
Thank you, #David Jacquel
{% assign noDisplay = "CATEGORY" | split: "," %}
{% assign cat_list = site.categories %}
{% if cat_list.first[0] == null %}
{% for category in cat_list %}
<li>{{ category }} <span class="cat-count">{{ cat_list[category].size }}</span></li>
{% endfor %}
{% else %}
{% for category in cat_list %}
{% unless noDisplay contains category[0] %}
<li>{{ category[0] }} <span class="cat-count">{{ category[1].size }}</span></li>
{% endunless %}
{% endfor %}
{% endif %}
{% assign cat_list = nil %}
Lets say it's the code snippet:
<ul>
{% assign navigation = site.data.nav %}
{% for link in navigation %}
{% assign active = nil %}
{% for sublink in link.submenu %}
{% if page.url contains sublink.url %}
{% assign active = 'active' %}
{% endif %}
{% endfor %}
{% if page.url contains link.url %}
{% assign active = 'active' %}
{% endif %}
<li class="{{ active }}>
{{ link.text }}
{% if link.submenu %}
<ul>
{% for sublink in link.submenu %}
<li {% if page.url contains sublink.url %}class="active"{% endif %}>
{{ sublink.text }}
</li>
{% endfor %}
</ul>
{% endif %}
</li>
{% endfor %}
</ul>
The nav.yml file looks like this:
- text: First Menu
url: /modules/some text/introduction/
- text: Second Menu
url: /modules/some more text/intro-text/
submenu:
- text: Level Two First
url: /modules/level two first/intro-text/
- text: Level Two Second
url: /modules/level two second/intro-text/
So, every menu item renders and also works fine as it should be. But the only issue i'm getting here is the variable active isn't getting updated according to those if rather staying nil. Also the following line isn't getting that active class rendered even if the page.url contains sublink.url or link.url
<li {% if page.url contains sublink.url %}class="active"{% endif %}>
What might be the issue??
