Use less files in django templates - python

I've got some trouble to load and compile a less file in my django template.
First of all I load one main less file in my header.html :
header.html
<link rel="stylesheet" href="/static/lib/bootstrap-.3.2/css/bootstrap.min.css" type="text/css">
<link rel="stylesheet" href="/static/lib/select2-3.5.2/select2.css" type="text/css"/>
<link rel="stylesheet" href="/static/lib/magnific-popup/magnific-popup.css" type="text/css">
<link rel="stylesheet/less" href="/static/less/style.less" type="text/css">
The less is loading without any problem.
Now I want to load specific less file for a specific django app. For example, I have an app named "helpdesk" and I want to do something like this :
helpdesk.html
{% block header %}
{{ block.super }}
<link rel="stylesheet/less" href="/static/helpdesk/less/style_helpdesk.less" type="text/less">
<script type="text/javascript" src="/static/helpdesk/js/helpdesk.js" charset="utf-8"></script>
{% endblock %}
In this case, less is not loading or compiling. I tried to use some django modules like django-compressor or django-static-precompiler but I was not able to make them work.
I looked after this for hours so any help would be really appreciated. Thank you.

Alright, I retried to use the django-compressor module and it worked !
I followed this link which is well explained : http://marklmiddleton.com/2013/using-less-with-django-on-heroku/

Django base.html extended to homepage.html, static images appear, but home.css does not works

Problem: As the title says I am building a django project the base.html extended to homepage.html and works fine, static images appear, but home.css does not works anywhere.
Update
I have switched in the base.html
from this <link rel="stylesheet" href="{% static 'css/home.css' %}">
to this <link href="css/home.css" rel="stylesheet" />
than I have also tried this: <link rel="stylesheet" type="text/css" href="{% static 'css/home.css' %}" />
It deletes a formatting on -s that was caused by another previously used .css that has been deleted since but the formatting sticked on.
I have called this css property thickkk{color: red;}
many places in both base.html and home.html and it still not working.
I have also get the following error message if I inspect the site with/F12/consol/ 127.0.0.1/:1 Refused to apply style from 'http://127.0.0.1:8000/css/home.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
Update ERROR message

base.html
I have created a base.html that hold the navbar and the footer.
This also has the CSS imported from a static css and also from bootstrap
It finds the static files because it imports the images that are appearing both here and in the home page

I have read the following articles but they haven't answered my question:

As you have STATICFILES_DIRS remove STATIC_ROOT then type python manage.py collectstatic, then yes, then run your server again.
The server should respond with the correct MIME Type for JSONP application/javascript and your request should tell jQuery you are loading JSONP dataType: 'jsonp'
Please see this answer for further details ! You can also have a look a this one as it explains why loading .js file with text/plain won't work.

Configuring output of % static in django

I'm experimenting with django-distill (https://github.com/mgrp/django-distill) to generate a static site from a django project. i'm using django 1.10.8 . My main template contains:
<!-- Bootstrap Core CSS -->
{% load staticfiles %}
<link href="{% static "css/bootstrap.min.css" %}" rel="stylesheet" />
<!-- Custom CSS -->
<link href="{% static "css/landing-page.css" %}" rel="stylesheet" />
<link rel="stylesheet" type="text/css" href="//cdn.jsdelivr.net/jquery.slick/1.5.0/slick.css"/>
The paths to the css and js files are correct when I run the project locally on my windows system. However when I look at the source html I see:
on my windows system this works with a running sever, i.e.
http://127.0.0.1:8000/static/css/bootstrap.min.css
but it breaks with static files and I have to change these to
<link href="./static/css/bootstrap.min.css" rel="stylesheet" />
Is there any way to set % static to render to
./static/ instead of /static/

Adding documentation to django app - conflict with angular

I have created documentation for my Django app using apidoc library.
It creates docs using angular. App is running on Heroku.
Docs are working nicely when I open index.html file, but I cannot open them via http://localhost:5000/docs.
Firstly I got this error:
"Variables and attributes may not begin with underscores: '__' "
, which I was able to bypass by putting {% verbatim %} and {% endverbatim %} into the index.html file. (Which I'm not very happy with in the first place and would like to do it some other way).
Then the page is stuck on the loading screen, but when I open it in Chrome I have the following error:
"Uncaught SyntaxError: Unexpected token <" in polyfill.js:1 and
require.min.js:1
And also 3 warnings:
"Resource interpreted as Stylesheet but transferred with MIME type
text/html"
in vendor/bootstrap.min.cs, vendor/prettify.css and css/style.css
We are using apidocs also in other project with Node where it works perfectly, so I think it's an issue with Django. Since the documentation is generated automatically, I would prefer to introduce changes into the app, not docs.
I tried it on Chrome and Safari.
My questions
1. What can I do to make it work?
2. How can I make Django compatible with Angular without putting {%verbatim%} tags into index.html?
Here is my controller:
from django.shortcuts import render
def show_docs(request):
return render(request, 'index.html')
and url_pattern:
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
import my_app.controller
from django.views.decorators.csrf import csrf_exempt
urlpatterns = [
url(r'^docs/', my_app.controller.show_docs),
]
index.html head:
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<title>Loading...</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link href="vendor/bootstrap.min.css" rel="stylesheet" media="screen">
<link href="vendor/prettify.css" rel="stylesheet" media="screen">
<link href="css/style.css" rel="stylesheet" media="screen, print">
<link href="img/favicon.ico" rel="icon" type="image/x-icon">
<link href="css/apidoccustom.css" rel="stylesheet" media="screen, print">
<script src="vendor/polyfill.js"></script>
</head>
edit:
Thanks to answer from hubert, I was able to find the source of the problem.
It turns out, that Django doesn't work that good with RequireJS, which is used by api docs.
I had to add the following changes to the generated code to make it work:
Points 1-4 are for index.html, point 5, 6 are for main.js:
Add this line above tag:
{% load static %}
Add "{% static" + " %}" tags to all tags so it looks like this:
<link href="{% static "vendor/bootstrap.min.css" %}" rel="stylesheet" media="screen">
Add the same static tags to tags with polyfill.js and require.min.js:
<script src="{% static "vendor/polyfill.js" %}"></script>
<script data-main="{% static "main.js" %}" src="{% static "vendor/require.min.js" %}"></script>
Add {% verbatim %} at the beginning of and {% endverbatim %} at the end of , BUT BEFORE with require.min.js!
In main.js add following lines to paths at the beginning of the file:
apiProject: './api_project.js',
apiData: './api_data.js',
Change lines:
'./api_project.js',
'./api_data.js',
to:
'api_project',
'api_data',
From this two errors:
"Uncaught SyntaxError: Unexpected token <" in polyfill.js:1 and require.min.js:1
"Resource interpreted as Stylesheet but transferred with MIME type text/html"
I would assume that there is something wrong with loading your static files. Probably you have 404 or 500 on them and django loads then default route.
Check if you have correct routing for static files.

Django template: Embed css from file

I'm working on an email template, therefor I would like to embed a css file
<head>
<style>{{ embed 'css/TEST.css' content here }}</style>
</head>
instead of linking it
<head>
<link href="{% static 'css/TEST.css' %}" rel="stylesheet" type="text/css">
</head>
Any ideas?
I guess you could use include
<style>{% include "/static/css/style.css" %}</style>
https://docs.djangoproject.com/en/1.9/ref/templates/builtins/#include
But it might be better to load the contents of the css file in your view, and put it in the context of your view to send it to the template
You can use django-compressor package. It will add {% compress %} template tag that can join together bunch of JS or CSS files (or inlined code) and put it into template as new, big file or inlined code. For example to inline one CSS file, you can use:
{% compress css inline %}
<link href="{% static 'css/TEST.css' %}" rel="stylesheet" type="text/css">
{% endcompress %}
You can add more CSS files into one compress tag, they will be concatenated together and wrapped into one <style>tag.
Check usage examples for more details.
On solution would be the use of include:
<head>
<style>{% include "../static/css/TEST.css" %}</style>
</head>
But it is kind of messy!
You have to place a copy or link to your css-file in your templates directory. Or you use a hardcoded link as above, which may break in production.

Adding Google Fonts to Flask

So with flask I know that I can add CSS with
<link ... href="{{ url_for('static', filename='stylesheets/style.css') }}" />
but if I am adding a google font which usually in HTML looks like
<link href='http://fonts.googleapis.com/css?family=PT+Sans:400,700' rel='stylesheet' type='text/css'>
what do I need to edit/add for it to work with Flask?
Add the google font link to your index.html or any page that you want like this:
{% extends "base.html" %}
{% import "bootstrap/wtf.html" as wtf %}
{% block styles %}
{{ super() }}
<link rel="stylesheet" href="{{ url_for('static', filename= 'mystyle.css') }}">
<link href='http://fonts.googleapis.com/css?family=Open+Sans+Condensed:300' rel='stylesheet' type='text/css'>
{% endblock %}
Then, add the CSS font statement to your custom CSS file (mine is static/mysyle.css) :
body {
font-family: 'Open Sans Condensed', sans-serif;`
}
You can't use static here like you would normally for a link to a resource on the webserver. Your link is still essentially static but not related to anything you are serving. So you either put the Google font link directly in the HTML template, or as a variable expanding to the full link (which would be convenient if you aren't using the same header template everywhere and may change the font later).
