I am learning Django framework, I setup Django on my local host and successfully run my first app, and i downloaded some web app from git and then i tried to understand it but when i opened template html the format used their was completly different from original html format, so i just want to know what scripting, or language they are using to build html files, Here is a sample code
{% extends "admin/change_list.html" %}
{% load i18n %}
{% block object-tools-items %}
{% if not is_popup %}
<a href="{{ recoverlist_url }}" class="recoverlink btn">
<i class="icon-repeat"></i>
{% blocktrans with cl.opts.verbose_name_plural|escape as name %}Recover deleted {{ name }}{% endblocktrans %}</a>
{% endif %}
{{block.super}}
{% endblock %}
I am unable to get what {% %} doing here, Is it a scripting tag just like jsp or something else, If it is a scripting that what kind of script is it ? because normally html files starts with
<head>
tag.
Is it a scripting tag just like jsp or something else
Yes.
If it is a scripting that what kind of script is it ?
Django Template language
because normally html files starts with <head> tag.
It's not HTML. It's a template language that render and outputs HTML.
I'd suggest you go through the Django tutorial.

I have a regular website where HTML5, CSS3, JQUERY and static images have been used.
I also have a Blog written in Django and I would like to integrate it in the website.
I am really new to Django so I was wondering which is the best approach to use.
Should I integrate the website code as part of the Django project or there are some other solutions?
thanks!
You have 2 ways of integrating your current site with Django.
1) You can write API with DjangoRestFramework and make requests with jQuery AJAX in order to get content from Django.
2) You can use your current HTML files as your Django project templates for rendering content from Django.
You can use a Django template. The template defines placeholders and various bits of basic logic (template tags) that regulate how the document should be displayed. Usually, templates are used for producing HTML, but Django templates are equally capable of generating any text-based format.
If you've used a templating engine like ''. They look somehow similar.
<html>
<head>
<title>Ordering notice</title>
</head>
<body>
<h1>Ordering notice</h1>
<p>Dear {{ person_name }},</p>
<p>Thanks for placing an order from {{ company }}. It's scheduled to ship on {{ s\
hip_date|date:"F j, Y" }}.</p>
<p>Here are the items you've ordered:</p>
<ul>
{% for item in item_list %}
<li>{{ item }}</li>{% end for %}
</ul>
{% if ordered_warranty %}
<p>Your warranty information will be included in the packaging.</p>
{% else %}
<p>
You didn't order a warranty, so you're on your own when the products inevitably stop working.
</p>
{% endif %}
<p>Sincerely,<br />{{ company }}</p>
</body>
</html>

I recently started with django and I have experience with angularJS. I got pretty confused by the static media rendering of Django which uses the same moustache ({{ }}) as angular. So how to use angular expressions while working with django..
<body>
<h1>Including Static Media</h1>
<img src="{% static "rango.jpg" %}" alt="Picture of Rango" /> <!-- Images -->
</body>
Instead of using the rendering as it is, can i use something like
image src="/static/images/xyz.jpg"
However if I want to load my images or js script dynamically or if I have to make URL's dynamically using something like ng-href="#!/{{redirectService(parameters)}}". It seems that syntax of both frameworks conflict alot. Can anyone help me regarding this.?
Check out the {% verbatim %} tag and/or the {% templatetag %} tag.
From the docs:
verbatim
Stops the template engine from rendering the contents of this block
tag.
A common use is to allow a JavaScript template layer that collides
with Django’s syntax. For example:
{% verbatim %}
{{if dying}}Still alive.{{/if}}
{% endverbatim %}
You can also designate a specific closing tag, allowing the use of {% endverbatim %} as part of the unrendered contents:
{% verbatim myblock %}
Avoid template rendering via the {% verbatim %}{% end verbatim %} block.
{% endverbatim myblock %}
templatetag
Outputs one of the syntax characters used to compose template tags.
Since the template system has no concept of “escaping”, to display one
of the bits used in template tags, you must use the {% templatetag %}
tag.
The argument tells which template bit to output:
Argument | Outputs
————————————————|————————
openblock | {%
closeblock | %}
openvariable | {{
closevariable | }}
openbrace | {
closebrace | }
opencomment | {#
closecomment | #}
Sample usage:
{% templatetag openblock %} url 'entry_list' {% templatetag closeblock %}
I was working on an old django-cms project and was trying to edit base.html file and no changes are reflected when I reload the page.
But if I delete all the lines in that file the django runserver refuses to start showing error
django.core.exceptions.ImproperlyConfigured: The 'js' and 'css' sekizai namespaces must be present in each template, - or a template it inherits from - defined in CMS_TEMPLATES. I can't find the namespaces in 'project/cms/home.html'.
They why isn't other changes like adding a new class not reflected in the page reload or server restart.
NOTE:
The project is working good as it is. I was trying to modify it a little bit. Changes I made in the css pages are getting reflected when I reload the page. Issue is only when I try to edit HTML pages
For base.html, you need to have {% load cms_tags sekizai_tags %} in the file. Add {% render_block "css" %} to <head></head> and {% render_block "js" %} somewhere between <body></body>. Depending on the template files that inherit from base.html, certain portions may have been overwritten. For example, if you had:
{# base.html #}
{% block content %}
<div class="example-class"></div>
{% endblock %}
But in another file say:
{# layout.html #}
{% extends "base.html" %}
{% block content %}
{% endblock %}
The div would not appear.
If however, you are talking about missing CSS files, you still need to include them in <head> for it to be displayed. render_block "css" is for django-cms css files that are included in plugins etc. I usually use a LESS or SCSS compiler to include CSS into my projects.
Hope that helps. Post more details for a better diagnosis.
In my django model I have to store html data as string like
item = RocketuItem(text=text, page_url=url, page_number=page_number, page_down=page_down)
and text =
<section> <h2>Object-oriented Python and Beginner Django</h2> <ul>
When i pull this in template i use ..
{% for page in pages %}
<div>{{ page.page_url|safe }}</div>>
<div>
{{ page.text|safe }}
I m using safe as it dosent display $lt etc [basically '<' gets converted to < if i dont use it]
This is wht i see at output on the page
<section> <h2>Object-oriented Python and Beginner Django</h2> <ul>
What i really want is for the code fro 'text' to be a part of the div so that it well get that formatting and show..
Object-oriented Python and Beginner Django
How do i do that ..
The safe filter should be enough to render the text as html in recent versions of Django. Try using:
{% autoescape off %} {{ content }} {% end autoescape %}
tags and see if that works for you.
Use this:
{% autoescape off %}{{ page.text }}{% endautoescape %}
Autoescape documentation
I have installed django-page-cms successfully i think. Like other cms, it is also for creating new pages. But I already have html pages in my project. How to integrate with that?
They want me to put place holder in html page, like:
{% load pages_tags %}
but I think this will bring the content from the already created page in admin
Can anyone tell me how to integrate with my existing pages?
First you need to create page in admin console. Then add the placeholder in your template
like what tutorial saying
{% get_page "news" as news_page %}
{% for new in news_page.get_children %}
<li>
{{ new.publication_date }}
{% show_content new body %}
{% endfor %}
