I have recently seen one HTML page.The code is embed with curly braces.Values for tags and loops are closed by curly braces.
{% if authenticated %}
<h1>Current User</h1>
<p>{{user}}</p>
{% else %}
<h1>Current User</h1>
<p>None</p>
{% endif %}
What is the actaul use of these type of code?
Is HTML embedded with any other language?
This may be Django script templates. Find more here.
This looks like the HTML is enriched with underscore.js or a similar templating engine.
It's used for displaying JavaScript data in your HTML without the need to know how JavaScript works.

I'd like to create something like a shortcode for a blockquote in Jekyll. It should include the quote source in a nicely formatted way.
The shortcode could look like this:
{% quote author="My Author" %}
This is the quoted content
spanning multiple lines
And paragraphs
{% endquote %}
What's the best way to achieve this in Jekyll? Can it be that there is no way to provide multiple arguments to a Jekyll tag plugin?
I have found a blog post that provides multiple attributes using string concatenation or JSON.
My Research
I have found two systems in Jekyll that can be used similar to shortcodes:
HTML Includes
Custom Tags
To summarize, both methods only provide a single attribute to the Ruby code, the content. Below, you will find the limitations of both solutions.
HTML Includes limiations
https://jekyllrb.com/docs/includes/
An include in use looks like this:
{% include note.html content=download_note %}
It is possible to use content from captures for parameters, so we could create the following include file:
<blockquote>
{{ include.quote | markdownify }}
<p><em>{{ include.author }}</em></p>
</blockquote>
And use it in a blog post like this:
{% capture quote %}
This is the quote content
spanning multiple lines
And paragraphs
{% endcapture %}
{% include quote.html quote=quote author="My Author" %}
It works, but in my opinion, it's not really a nice approach to use when writing blog posts.
Custom Tags limiations
https://jekyllrb.com/docs/plugins/tags/
Sounds promising, but the documentation only shows two ways to use them:
{% render_time page rendered at: %}
and
{% render_time %}
page rendered at:
{% endrender_time %}
I'm working on a personal Django project where my plan is to make some sort of function in my site in form of a CSS Marquee (scrolling text).
I was able to make a marquee.html file with the code from here, and use it on several pages on my site using {% include "marquee.html" %} blocks, but the displayed string in the marquee is within the HTML file itself (marquee.html) between <p>-tags
Is there any way to send a variable/string along with a {%include "" %} block that replaces/adds to the <p> tags at the end of the marquee code?
(e.g. {% include "marquee.html" {{ stringToDisplay }} %} )
The current context is available for the included template. You can use the "with" option to send any additional context.
{% include "marquee.html" with message="Hello" %}
and in your marquee.html template
<div>{{ message }}</div>
The include documentation is here
I'm trying to display some HTML markup in a blog, and would like to know if there is a way to wrap a section of my Django template directly, without putting it into a context variable.
For example, I would like to output a bunch of code, some of it JavaScript, and some of it HTML, and some of it CSS. If I enter in the code directly into my Django template, and wrap it in some pre tags:
<pre>
/* Here is the markup I want to display: */
... lots of HTML
</pre>
the HTML tags are rendered.
Of course, to display:
<
I should use
<
and to display
>
I should use
>
I tried adding the Django tag {% autoescape on %} around the code section, but it had no effect because I'm not rendering a context variable.
I would like to know if there is an easier way than replacing every occurrence of < with < and every occurrence of > with >
I also know that if I put the code that I want to display into a context variable, then in my template, just displaying that context variable would automatically escape the code.
But I would rather just be able to directly cut and paste the code I want to display into my template. Is there a way to do this and display the HTML tags (i.e.
<h1> Heading Level 1 </h1>
without writing it in my template as:
<h1> Heading Level 1 </h1>
You have to use xmp tags.
<xmp>
<h1>Testing Html</h1>
</xmp>
This question is old, but it pops on search engines and no answer is correct imo.
Sławek Kabik's is deprecated, Smit Patel's is overly complicated (it bloats views).
In order to do what OP asked for, you have to use the force_escape built-in filter in a {% filter %} tag.
Example:
<pre>
<code>
{% filter force_escape %}
<span class="hello">Anything HTML really</span>
{% endfilter %}
</code>
</pre>
Output:
<pre>
<code>
<span class="hello">Anything HTML really</span>
</code>
</pre>
NOTE: Before you try to implement manually, please have a look at ckeditor.

if this is not what you are looking for, then only proceed with answer.
Just Wrap your variable inside following Django template tag.
{% autoescape off %}
{{your_variable_here}}
{% endautoescape %}
put HTML code in "your_variable_here" variable And Django Will Display It as HTML. All HTML Tags will Work.
EDIT:
Sorry, I missed important part to mention.
in views do this
from django.template.loader import render_to_string
rendered = render_to_string('my_template.html', {'foo': 'bar'})
and pass this rendered string to template variable and render the given template inside other template by putting lines
{% autoescape off %}
{{rendered}}
{% endautoescape %}
This feels like a really silly issue, but I'm confused by the behavior of django-zinnia, a blog creation module.
When I test enter a plain text post, it appends each sentence with html < p > tags the browser doesn't read as html.
Example, if I enter this into the database (no html):
The entry from the db renders on page itself like this as if the < p > markup was plain text:
Within Zinnia, these html tags are being generated as part of the {{ object_content }} object in _entry_detail_base.html
<div class="entry-content">
{{ object_content }}
</div>
I've looked through the entry.py models within Zinnia and I'm having trouble identifying where these tags are coming from or how they're being passed in in a way the browser doesn't interpret them for what they are (html). Is there a filter I can apply that might solve this? thanks
That's the default behavior for Django templates. Use {{ object_content|safe }} or {% autoescape off %} {{ object_content }} {% endautoescape %} (for multiple variables) to prevent html entities from being escaped.
Note that using the safe filter doesn't automatically mean the output is not escaped if you use another filter after it.
Check the Zinnia's source code: https://github.com/Fantomas42/django-blog-zinnia/blob/master/zinnia/templates/zinnia/_entry_detail_base.html
It's using |safe template tag:
<div class="entry-content">
{{ object_content|safe }}
</div>
When DEBUG=True a variable containing HTML is just printed in the template and not interpeted as HTML. This is the correct behavior.
On the other hand, when DEBUG=False (just changing this) the variable's content is interpreted as HTML and I cannot understand why. I'm not using the safe filter.
My template is as follows:
<pre id="copy-source-{{ forloop.counter }}">
<code>{{ code }}</code>
</pre>
In one case, code happens to be HTML code, specifically:
<img src="bblabla" />
and the page displays the image instead of the code, even if it's inside a pre-code!?
Try this
{% autoescape off %}
{{var_containing_html}}
{% endautoescape %}
I hope this will help.
Good luck.
