I have page front matter with multiple levels. My page front matter looks like this:
grids:
- template: section
background_image: "/uploads/2018/05/01/q-mark.png"
rows:
- template: row
stack-columns: tablet-s
cols:
- template: column
title: "Column-1 Title"
- template: section
background_image: "/uploads/2018/05/01/lk.png"
rows:
- template: row
stack-columns: tablet-s
cols:
- template: column
title: "Column-2 Title"
rows:
- template: row
stack-columns: tablet-l
cols:
- template: column
title: "Column-3 Title"
I can display the first-level template name for both of my grids:
{{ range .Params.grids }}
{{ .template }}
{{ end }}
How can I return the template name of rows and cols within the loop?
I figured it out. You can use a nested range to access parameters with multiple levels:
{{ range .Params.grids }}
<p>Grid template name: {{ .template }}</p>
{{ range .rows }}
<p><strong>row template name: </strong>{{ .template }}</p>
{{ range .cols }}
<p><em>col template name:</em> {{ .template }}</p>
{{ end }}
{{ end }}
{{ end }}
This displays:
Grid template name: section
row template name: row
col template name: column
Grid template name: section
row template name: row
col template name: column

I'm trying to figure out why my jinja2 template (and ansible for that matter) cannot find my variables in my inventory file.
Here is my inventory file:
all:
hosts:
test05:
ansible_host: 192.168.x.x
filebeat:
version: 7.15.2
applog:
- title: Separate Application Log Path with Tags
type: log
paths:
- /var/log/something/moresomething/current
tags: '["something", "application"]'
- title: Separate Application Log Path, with Tags, and "decode_json_fields" processor.
type: log
paths:
- /var/log/something/moresomething/blah-shell.log
tags: ["application", "something"]
fields: ["message"]
depth: 2
- title: Separate Application Log Path, with Tags, and Multiline fields
type: log
paths:
- /var/log/something/moresomething/production.log
tags: ["application", "something"]
multiline_type: pattern
multiline_patern: 'Started'
multiline_negate: true
multiline_match: after
Then attempting to get the first title. I'm doing the following:
- name: debugging
debug:
var: filebeat.applog.title
when I run this I end up getting filebeat.applog.title: VARIABLE IS NOT DEFINED! which I think is good since it doesn't know what title I want. So changing this to
- name: debugging
debug:
var: filebeat.applog.0.title
I end up getting what I want filebeat.applog.0.title: Separate Application Log Path with Tags. However, how do I use this in a jinja2 template?
I have the following for a template, I know I need to update this to loop through the different items in my inventory. That's a different problem on how to loop through this.
title: {{ filebeat.applog.title }}
- type: {{ filebeat.applog.type }}
enabled: true
paths:
- {{ filebeat.applog.path }}
tags: {{ filebeat.applog.tags }}
{% if filebeat.applog.fields is defined %}
processors:
- decode_json_fields:
fields: {{ filebeat.applog.fields }}
max_depth: {{ filebeat.applog.depth }}
target: {{ filebeat.applog.target | default "" }}
{% endif %}
{% if filebeat.applog.multiline_pattern is defined %}
multiline.type: {{ filebeat.applog.multiline_type }}
multiline.pattern: {{ filebeat.applog.multiline_pattern }}
multiline.negate: {{ filebeat.applog.multiline_negate }}
multiline.match: {{ filebeat.applog.multiline_match }}
{% endif %}
each time I get the following, even when I do use {{ filebeat.applog.0.logtitle }} in the template:
fatal: [test05]: FAILED! => changed=false
msg: |-
AnsibleError: template error while templating string: expected token 'end of print statement', got 'string'. String: title: {{ filebeat.applog.title }}
- type: {{ filebeat.applog.type }}
enabled: true
paths:
- {{ filebeat.applog.path }}
tags: {{ filebeat.applog.tags }}
{% if filebeat.applog.fields is defined %}
processors:
- decode_json_fields:
fields: {{ filebeat.applog.fields }}
max_depth: {{ filebeat.applog.depth }}
target: {{ filebeat.applog.target | default "" }}
{% endif %}
{% if filebeat.applog.multiline_pattern is defined %}
multiline.type: {{ filebeat.applog.multiline_type }}
multiline.pattern: {{ filebeat.applog.multiline_pattern }}
multiline.negate: {{ filebeat.applog.multiline_negate }}
multiline.match: {{ filebeat.applog.multiline_match }}
{% endif %}
I'm not sure what I'm missing or doing wrong. I'm thinking I'm doing something wrong since this the first time doing something like this.
So the template you have should either:
have a for loop to iterate over filebeat.applog
OR
reference n'th element of filebeat.applog
Aside from that, there are some errors like below:
1.
target: {{ filebeat.applog.target | default "" }}
This is the main one, and this is what the error message is complaining about, i.e. got 'string'. The correct usage for default filter is {{ some_variable | default("") }}.
2.
{% if filebeat.applog.multiline_pattern is defined %}
In the inventory this variable is mis-spelled, i.e. multiline_patern (missing one "t"). Fix this in your inventory.
3.
when I do use {{ filebeat.applog.0.logtitle }} in the template
This should be {{ filebeat.applog.0.title }} to work.
Considering the above fixes, a template that loops over filebeat.applog such as below should work:
{% for applog in filebeat.applog %}
title: {{ applog.title }}
- type: {{ applog.type }}
enabled: true
paths: {{ applog.paths }}
tags: {{ applog.tags }}
{% if applog.fields is defined %}
processors:
- decode_json_fields:
fields: {{ applog.fields }}
max_depth: {{ applog.depth }}
target: {{ applog.target | default("") }}
{% endif %}
{% if applog.multiline_pattern is defined %}
multiline.type: {{ applog.multiline_type }}
multiline.pattern: {{ applog.multiline_pattern }}
multiline.negate: {{ applog.multiline_negate }}
multiline.match: {{ applog.multiline_match }}
{% endif %}
{% endfor %}
I am trying to display an image in my post list.
In order to achieve that I added some tags in my post.md:
---
title: "Hello"
header_image: /images/blog/2019/water.jpg
images: /images/blog/2019/water.jpg
resources:
src: /images/blog/2019/water.jpg
title: "The image I want"
---
Then I edited list.html and tried different things:
{{ define "main" }}
<div class="archive animated fadeInDown">
<ul class="list-with-title">
<div class="listing-title">{{.Title}}</div>
{{ range .Pages }}
<ul class="listing">
<div class="listing-item">
<div class="listing-post">{{ .Title }}
{{ with .Resources.ByType "image" }}
<div class="Image">
{{ range . }}
<img src="{{ .RelPermalink }}">
{{ end }}
</div>
{{ end }}
{{ $.Param "header_image" }}
-- {{ range .Page.Resources }}
THERE IS ONE ITEM => NOT WORKING
{{ end }} <<
<div class="post-time"><span class="date">{{.Date.Format "Jan 2" }}</span></div>
</div>
</div>
</ul>
{{ end }}
</div>
{{ end }}
But when I try to display Resources, I always get [] (nothing)
Any idea what I am doing wrong?
I don't think your {{ $.Param "header_image" }} is working, either.
The way to access your custom, non-standard variables on pages, as well as sites, is through the .Params object, e.g. .Params.header_image. Note the small letter at the beginning, as opposed to capital letters for built-in params.
Page-level params on the Hugo Docs
Custom page params
To access
---
header_image: /images/blog/2019/water.jpg
---
you can use this in your page template.
{{ .Params.header_image }}
Resources
Page resources on Hugo Docs
It seems that resources is actually an array of objects, and with yaml, you should actually have something like this (note the dash):
resources:
- src: /images/blog/2019/water.jpg
title: "The image I want"
Also mind that this feature seems to only be available only for page bundles
Debugging
You can use {{ printf "%#v" .Resources }} for debugging.
I am trying to create email templates having html tokens in golang. I have searched all over the web and found
"html/template"
library. It supports token format like below
Hello {{.Name}}
Confirm email address
But the requirement for html token is something like
Name: {{ test.name }}
Phone: {{ test.phone }}
Address: {{ test.address }}, {{ test.city }}, {{ test.state }} {{ test.zip }}
I could not found such token system in golang or any library supporting such format. Can anyone please tell how can I achieve to create such tokens. There should be no dot before the attribue. either it should be only the attribute like {{Name}} or like {{ test.name }}.
Thank you!
If you can use a $ before attribute names, you can use the template's [with][1] action. Something like:
tmpl :=`
{{ with $test := . }}
Name: {{ $test.Name }}
Phone: {{ $test.Phone }}
Address: {{ $test.Address }}, {{ $test.City }}, {{ $test.State }} {{ $test.Zip }}
{{ end }}
`
Note that each struct field needs to be exported.
I'm trying to loop over items and render it in separate template, but {{ . }} in item.html contains root variables instead of a single item. I tried to assign item to a variable {{ range $i, $item := .Items }}, but the result is the same.
<!-- list.html -->
{{ range .Items }}
{{ . }} this one is OK
{{ render "item.html" }}
{{ end }}
<!-- item.html -->
{{ . }} this one is not
I've got a design for my post page that is made up of text and images, more specifically, galleries. Take a look at the illustration below:
I've got these galleries set up my front matter like so:
---
gallery-1:
rows:
- images:
- { url: '1.jpg'}
- images:
- { url: '2.jpg'}
- { url: '3.jpg'}
gallery-2:
rows:
- images:
- { url: '4.jpg'}
- { url: '5.jpg'}
---
Is there a way to print these galleries to the page on my .md file. I know the code below won't work, but something similar?
This is my markdown
[gallery-1]
This is more markdown
[gallery-2]
Is something like this possible with Jekyll?
Any help with this is appreciated. Thanks in advance!
First, let's simplify your yaml front matter :
---
galleries:
# gallery number one
1:
# row one in gallery one
-
- { url: '1.jpg', alt: 'alt 1'}
# row two in gallery one
-
- { url: '2.jpg', alt: 'alt 2'}
- { url: '3.jpg', alt: 'alt 3'}
# gallery number two
2:
# row one in gallery two
-
- { url: '4.jpg', alt: 'alt 4'}
- { url: '5.jpg', alt: 'alt 5'}
other front matter like title, ...
---
Your .md file :
Markdown
{% include gallery.html gallery=1 %}
Other markdown
{% include gallery.html gallery=2 %}
And then the _includes/gallery.html file :
{% comment %}-----------------
- This page receives a gallery index (include.gallery)
- It then assign the gallery[include.gallery] to the rows variable
%}-----------------{% endcomment %}
{% assign rows = page.galleries[include.gallery] %}
{% comment %}%}-----------------
We now loop over rows
%}-----------------{% endcomment %}
{% for row in rows %}
<div class="row">
{% comment %}%}-----------------
and then loop over images in row
%}-----------------{% endcomment %}
{% for img in row %}
<p>src="{{ site.baseurl }}{{ img.url }}" alt="{{ img.alt }}"</p>
{% endfor %}
</div>
{% endfor %}
