I have a taxonomy type that looks like the below:
packages:
slug: packages
singular_slug: package
behaves_like: grouping
options: { unsupported: "Unsupported Description", supported: "Supported Description" }
has_sortorder: true
listing_template: listing_packages.twig
Is it possible to output the option key rather than the value from within my template? When I'm using the "packages/unsupported" url, {{ slug }} currently outputs "Unsupported Description" rather than "unsupported" which is fine, except I need both.
I was hoping to have some custom blocks within my listing template based on the slug i.e.
{% setcontent block = "block/" ~ slug %}
...but obviously it'd be better in this case to use key rather than value
You can iterate over the keys (for some reason this only worked when I initialised the option_key variable first):
{% set option_key = '' %}
{% for key, value in taxonomy.options %}
{% if value == slug %}
{% set option_key = key %}
{% endif %}
{% endfor %}
{% setcontent block = "block/" ~ option_key %}

In my Jinja template, model.DataType value can be user defined or built in. My requirenement is if model.DataType start with the three letters ARR, then do a specific operation.
Example of values:
ARRstruct124
ARR_int123
ARR123123
CCHAR
UUINT
etc.
{% set evenDataType = model.eventDataType %}
{%if evenDataType | regex_match('^ARR', ignorecase=False) %}
// do the operation
{%else%}
// do the operation
{% endif %}
With this template, I am getting the error
{%if evenDataType | regex_match('^ARR', ignorecase=False) %}
jinja2.exceptions.TemplateAssertionError: no filter named 'regex_match'
There is indeed no regex_match filter in the Jinja builtin filters. You might have found some examples using it, but this is an additional filter provided by Ansible, so it won't work outside of Ansible.
This said, your requirement does not need a regex to be fulfilled, you can use the startswith() method of a Python string.
So, you template should be:
{% set evenDataType = model.eventDataType %}
{% if evenDataType.startswith('ARR') %}
`evenDataType` starts with 'ARR'
{% else %}
`evenDataType` does not starts with 'ARR'
{% endif %}
I'm passing a dictionary in the context in my views.py to my html template. How do I know access a value in the template based on a particular key. For instance I'd wanna do something like {{ dictionary.keyname.value }} but I don't know the correct syntax and for some reason I can't seem to find the documentation.
I want to achieve the same effect as this without having to use a for loop:
<b>Calories</b>
{% for key, value in output.items %}
{% if key == "calories" %}
{{ value }}
{% endif %}
{% endfor %}
You just want {{ output.calories }}.
I've got some component button:
{% assign class = "c-button " | append: include.class %}
{% assign type = include.type | default: "button" %}
{% assign content = include.content %}
{% if content %}
<button class="{{ class }}"
type="{{ type }}">{{ content }}</button>
{% endif %}
Now i want include a button with some values and content out an array:
{% include components/button.html
type = "button"
content = site.data.contentful.spaces.links.navbar[0].item_name
class = "pretty-button"
%}
I receive this error:
Liquid Exception: Invalid syntax for include tag: type = "button"
content = site.data.contentful.spaces.links.navbar.[0] class =
"pretty-button" Valid syntax: {% include file.ext param='value'
param2='value' %}
Is it not possible to assign an array value to a include variable?
Thanx for any help!
The include tag currently does not parse variable values with syntaxes like navbar[0]. Only "simple quoted strings" or "variables comprising alphanumericals and/or a hyphen".
content = site.data.contentful.spaces.links.navbar[0].item_name will be flagged but content = site.data.contentful.spaces.links.navbar.item_name will be passed through for evaluation.
You can use the capture tag to pre-eval the flagged variable and then inserted via a simple variable:
{% capture my_content %} site.data.contentful.spaces.links.navbar[0].item_name {% endcapture %}
{% include components/button.html type = "button" content = my_content class = "pretty-button" %}
Note that include tag is defined in a single line due to a bug in the parse regex that ignores multiline strings. The patch is included in jekyll-3.8.0.pre.rc1
In my front matter for some pages (not all) I have:
---
top-navigation:
order: 2
---
Using liquid I want to filter all site pages which have a top-navigation object and sort by top-navigation.order.
I'm trying sort:'top-navigation.order' but that's throwing an exception of undefined method [] for nil:NilClass. I tried where:"top-navigation", true but it's not equating truthy values.
How can I filter for pages that have top-navigation and then sort?
Two steps:
Create an array with pages that contains the top-navigation key.
We create an empty array and then push the items that have the key.
{% assign navposts = ''|split:''%}
{% for post in site.posts %}
{% if post.top-navigation %}
{% assign navposts = navposts|push:post%}
{% endif %}
{% endfor %}
Sort the above array by top-navigation.order
{% assign navposts = navposts|sort: "top-navigation.order"%}
Printing results:
{% for post in navposts %}
<br>{{ post.title }} - {{post.top-navigation}}
{% endfor %}
For pages use site.pages.
In Jekyll 3.2.0+ (and Github Pages) you can use the where_exp filter like so:
{% assign posts_with_nav = site.posts | where_exp: "post", "post.top-navigation" %}
Here, for each item in site.posts, we bind it to the 'post' variable and then evaluate the expression 'post.top-navigation'. If it evaluates truthy, then it will be selected.
Then, putting it together with the sorting, you'd have this:
{%
assign sorted_posts_with_nav = site.posts
| where_exp: "post", "post.top-navigation"
| sort: "top-navigation.order"
%}
Liquid also has the where filter which, when you don't give it a target value, selects all elements with a truthy value for that property:
{% assign posts_with_nav = site.posts | where: "top-navigation" %}
Unfortunately, this variant does not work with Jekyll.
At its most basic level I need to append a partial object path onto an existing object path. In this particular instance I can't use plugins.
Say you have an object path:
{{ site.data.grants.2015.Return.ReturnHeader.ReturnTypeCd }}
Which, of course, can also be referenced as follows:
{% assign var = "ReturnTypeCd" %}
{{ site.data.grants.2015.Return.ReturnHeader[var] }}
How would I go about adding additional levels of nesting to the variable?
{% assign xTest = "Return.ReturnHeader.ReturnTypeCd" %}
{{ site.data.grants.2015[xTest] }}
//does not work
I've played around with both dot and bracket notations and using append as well as capture, but can't seem to find a solution that works.
This works :
Data file is _data/grants.yml
"2015":
Return:
ReturnHeader:
ReturnTypeCd: "Et hop !"
Getting deep target with a "dotted" string :
{% assign dataPath = site.data.grants.2015 %}
{% assign target = "Return.ReturnHeader.ReturnTypeCd" %}
{% comment %} ++++ Transform target string to an array {% endcomment %}
{% assign labels = target | split:"." %}
{% comment %} ++++
Looping in labels array and reassigning dataPath on each loop.
This goes deeper and deeper in the data tree
++++ {% endcomment %}
{% for label in labels %}
<h2>Label : {{ label }}</h2>
{% assign dataPath = dataPath[label] %}
<p>dataPath : {{ dataPath }}</p>
{% endfor %}
