Django Template Whitespace - html

I'm at a loss as to what is happening here. I'm getting undesired spaces between span elements when I use indentation in the template. Ie:
<div>
<span class="empty-space"></span>
{% for dia in dias %}
<span class="{% cycle "dia-par" "dia-impar" %}">{{ dia }}</span>
{% endfor %}
</div>
So I'm forced to write the less readable form:
<div>
<span class="empty-space"></span>{% for dia in dias %}<span class="{% cycle "dia-par" "dia-impar" %}">{{ dia }}</span>{% endfor %}
</div>
To get the desired functionality. I already tried with margin-left/right:0px. and {%spaceless%}. Any Ideas what is going on?

The span is an inline element so white space is taken into an account.
Django has a spaceless tag which you can use to resolve this, as that removes the spaces between tags:
https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#spaceless
It allows you to keep the template structure as is, but the output would be without the extra spaces.
You can also attack it from the CSS level, and set the span's display to inline-block.

what is ? in pagination hyper links

Hi im reading a book about django and in pagination template i see a ? but i do not know why is it there.I searched but got no answer.
Here is the template :
<div class="pagination">
<span class="step-links">
{% if page.has_previous %}
Previous
{% endif %}
<span class="current">
Page {{ page.number }} of {{ page.paginator.num_pages }}.
</span>
{% if page.has_next %}
Next
{% endif %}
</span>
</div>
what is the question mark in the address of page in ???
The ? basically represents a query parameter in the URL.
In many cases, the beginning of the query string is marked with a question mark and the various parameters that make up the query string are separated with an ampersand, but other syntaxes are also possible.
domain.com?parameter1=value1&parameter2=value2&parameter3=value3

html in django page to limit length of text

I am building a tool in django. It allows myself, and others, to make entries (imagine a journal) for various 'topics'. When the topic is clicked a page opens ('topic' page) that shows the entries. I am trying to limit the length of that text to 200 characters such that if someone wants to see the whole entry, they need to click on that entry to open it up to its specific page.
I have tried putting a maxlength="200" in a few different places. But nothing worked. The only thing I did that kind of worked was to create a 'textarea' with a maxlength="200" but that was visually odd and unappealing. I know there has to be some way to limit the length in the existing code, without creating a new area and putting the entry in there.
Below is the code for the 'topic.html' page. I am thinking that should be enough. If you need the views.py or models.py, let me know.
{% extends "AARs/base.html" %}
{% block header %}
<h2>{{ topic }}</h2>
{% endblock header %}
{% block content %}
<p>
Add new action
</p>
{% for action in actions %}
<div class="panel panel-default">
<div class="panel-heading">
<small>
{{ action.date_added|date:'M d, Y H:i' }}
</small>
<small> Read or Edit Action</small>
</div>
<div class="panel-body">
<small>
<input type="text" name="action" maxlength="10">
{{ action.text|linebreaks }}
</small>
</div>
</div>
{% empty %}
No actions have been added yet.
{% endfor %}
{% endblock content %}
You might be looking for the truncation filters in Django's template language:
truncatechars
truncatechars_html
truncatewords
truncatewords_html
As an example, quoting from the docs:
{{ value|truncatewords:2 }}
If value is "Joel is a slug", the output will be "Joel is …".

Jekyll and modular/atomic design

I am currently looking at developing a "static" website, few pages only. However, by design, I can tell there is going to be repetitive layouts/patterns. I am thinking doing a data-oriented approach, with my HTMLs being as reusable as possible. Here is an example:
index.html:
<div>
{% include organisms/topBanner.html
tp-title=site.data.home.topbanner.title
tp-select-blurb=site.data.home.topbanner.select.blurb
button-text=site.data.generic.buttons.getstarted
button-link=site.data.generic.links.gosomewhere
%}
</div>
then my organisms/topBanner.html:
<div class="tb">
<h1>
{{ include.tp-title }}
</h1>
<div>
<h2>{{ include.tp-select-blurb }}</h2>
<div>
{% include atoms/button.html
%}
</div>
</div>
</div>
finally my atoms/button.html:
<a class="button" href="{{ include.button-link }}">{{ include.button-text }}</a>
I have multiple JSON file under _data that basically hold the texts. An example for the button would be a _data/generic/buttons.json:
{
"getstarted": "GET STARTED",
"completesurvey": "COMPLETE THE SURVEY"
}
or links.json:
{
"gosomewhere": "/go-somwhere",
"surveypage": "/survey"
}
So this means you need to pass all your data from the top level include of the organism so every bits in it would have its data. That way the example of that button is that the HTML is defined only once and the data is bound to it. And for a second button to be in the topBanner you could do something like this:
index.html:
<div>
{% include organisms/topBanner.html
tp-title=site.data.home.topbanner.title
tp-select-blurb=site.data.home.topbanner.select.blurb
b-getstarted-text=site.data.generic.buttons.getstarted
b-getstarted-link=site.data.generic.links.gosomewhere
b-survey-text=site.data.generic.buttons.completesurvey
b-survey-link=site.data.generic.links.surveypage
%}
</div>
and in the topBanner.html, you rebind the data to the dedicated button:
<div class="tb">
<h1>
{{ include.tp-title }}
</h1>
<div>
<h2>{{ include.tp-select-blurb }}</h2>
<div id="getstarted">
{% include atoms/button.html
button-text=include.b-getstarted-text
button-link=include.b-getstarted-link
%}
</div>
<div id="survey">
{% include atoms/button.html
button-text=include.b-survey-text
button-link=include.b-survey-link
%}
</div>
</div>
</div>
This approach means everything is data driven, there is no repetition/'copy/paste' of HTML, it all works through includes and you can apply atomic design pattern (http://patternlab.io/).
Wanna change the text of the button from 'GET STARTED' to 'LET'S START'? Go to the data/generic/buttons.json and change it there. The whole website now has the text changed.
The drawback is the fact that all the data has to trickle down from top level. Readability might be bad.
First use of Jekyll for me, and waned to have your opinion on this. What is good practice for static website dev like this? Is it easier to have a buttonGetStarted.html that includes a more generic button.html, and pass the data to button.html from buttonGetStarted.html? Like:
buttonGetStarted.html:
{% include atoms/button.html
button.text=site.data.generic.buttons.getstarted
button.text=site.data.generic.links.gosomewhere
%}
and then include buttonGetStarted every time I need it on the page? But then if I need a new button for the survey, I need to create another html buttonSurvey.html and so on... Sure on the code you see an {% include buttonSurvey.html %} which is easy to read and understandable straight away what this button is about. So this:
{% include button.html button.text=site.data.generic.buttons.getstarted %}
with only one file button for all the buttons, or
{% include buttonGetStarted.html %}
with creation of a new HTML file everytime I need a new button?
Thanks

Disclaimer : As this question is primarily opinion-based (see SO help on this), I've voted to close it.
However, I can give my two cents. Quote are from Atomic Design Methodology.
Atom
[...] elements that can’t be broken down any further without ceasing to be functional
atom/buttons.html
<a class="button" href="{{ include.datas.button-link }}">
{{ include.dats.button-text }}
</a>
Molecule
[...] molecules are relatively simple groups of UI elements functioning together as a unit.
Here the question is : "do we need datas from organism / page for our molecule to work ?"
Yes : Datas will be passed by the parent organism. molecule/buttonGetStarded.html looks like (Note : this molecule is Homonuclear, but is functionnal.)
{% include button.html datas=include.buttonDatas %}
No : Datas will be set from inside the molecule (imaginary data structure)
{% include button.html datas=site.data.buttonDatas.getStarted %}
So in your case, I think that organism/topBanner.html can be composed like this (simplified for readability) :
{{ include.tp-title }}
<h2>{{ include.tp-select-blurb }}</h2>
<div id="getstarted"> {% include molecules/buttonGetStarted.html %}</div>
<div id="survey"> {% include molecules/buttonSurvey.html %}</div>
As I guess that your data files can be used for Internationalization (I18n) purpose. The molecule language doesn't need to be passed all the way down. It can be guessed by the molecule itself.
{% if page.language == nil %}
// if no language variable in page's front matter
// we default to site language set in _config.yml
{% assign language = site.language %}
{% else %}
// language variable present in front matter
{% assign language = page.language %}
{% endif %}
// get datas depending on guessed language
{% assign datas = site.data[language] %}
// this can even be more atomic with
{% assign datas = site.data[language]['buttonSurvey'] %}
// include the atom with correct language datas
{% include atom/button.html datas=datas %}
Note that this logic can even be factorized.

For loop duplicating code in Jekyll / Liquid

My input is pretty simple. I'm pulling from a data file to fill <p> with content then running the method markdownify, but the output duplicates the <p> element in (to me) unexpected ways.
Please advise! And thank you.
Sample Input:
{% for item in site.data.filename.item %}
<p style="display:{{ item.display }}" id="{{ item.nav }}">{{ item.content | markdownify }}</p>
{% endfor %}
And the Output:
<p id="test" style="display:block"></p>
<p>testing output</p>
<p></p>
Is there something going on with my liquid syntax? Many thanks in advance
This is typically what happens when you nest paragraphs. You should remove HTML tags from your content.
{{ item.content | strip_HTML}}
https://docs.shopify.com/themes/liquid/filters/string-filters#strip_html
If you want to keep the html formatting, you can use a div to wrap the content, like this:
{% for item in site.data.filename.item %}
<div style="display:{{ item.display }}" id="{{ item.nav }}">{{ item.content | markdownify }}</div>
{% endfor %}
Did you try removing markdownify?
Internally jekyll framework will apply markdownify so we do not need to write markdownify
I tried your code with markdownify removed and got single lines of <p> duplicates.
strip_HTML option also works.
Either remove markdownify or put strip_HTML
Instead of display:{{ item.display }} try
display:{{ display }}
Should do the job! :)

django template inheritance use same tag multiple templates

I am using the django template system fine-though is there a way to use the same variable inheritance tag for more than one template without pulling in the data from the other template too.
<div id="content-container3">
{% block content-container2 %}{% endblock %}
</div>
So I want to use the above in say people.html template and test.html template.
for example:
{% extends "base.html "}
{% block content-container2 %}{% endblock %}
Though it cross refernces information from two templates in this case -does each variable inheriatnce tag have to be unique?
try to move this part of code to different file (content_container3.html) and use include tag... or I did not understand your question :)
I think you should try nesting blocks like the below example.
{% block first_section %}
{% block first_section_upper %}
{{block.super}}
{% endblock first_section_upper %}
<h1 class="display-5">Some content</h1>
<h5 style="color: white !important;" class="display-5"> *Your text here*</h5>
<p class="lead">The Algorithms that run our Universe</p>
{% block first_section_lower %}
{{block.super}}
{% endblock first_section_lower %}
{% endblock first_section %}
The h1 tag and p tags can be different for every new template. As far as i could understand, this might solve your problem.
