CSS showing on local computer, but not on Heroku (Python, Django)
I have built a website using both bootstrap styling, and also a stylesheet for other changes I wish to make along the way. I have it displaying a certain way on my local machine, but I can't get it refelected on my site. Is there something that I need to add to my settings.py file to know that it should read the static css file? Here is my html file for this one: {% load static %} <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <title> Insure Need </title> {% bootstrap_css %} {% bootstrap_javascript jquery='full' %} <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> </head> <body> <nav class="navbar navbar-expand-md navbar-light bg-light mb-4 border"> <a class="navbar-brand" href="{% url 'website:welcome' %}">InsureNeed</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span></button> <div class="collapse navbar-collapse" id="navbarCollapse"> <ul class="navbar-nav mr-auto"> <li class="nav-item"> <a class="nav-link" href="{% url 'website:insureNeeds' %}">InsureNeed</a> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'website:learn' %}">Learn</a> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'website:contact' %}">Contact</a> </li> </ul> </div> </nav> <main role="main" class="container"> <div class="pb-2 mb-2 border-bottom"> {% block page_header %}{% endblock page_header %} </div> <div> {% block content %}{% endblock content %} </div> </main> <!--{% include 'website/footer.html' %}--> </body> … -
Dockerfile - activate Python virtualvenv - ubuntu
I am trying to create an Docker Image that contains an Apache Webserver with Django. I am using virtual environments in my production environment and I don't know how to activate it in a Dockerfile.

How do I get my CreateAPIView to recognize the "validate' seciton of my serializer?

How to translate text in an external javascript file? (Django)
I have a JavaScript file that appends elements to the body according to the user interaction. Right now in my index.html template I'm declaring global variables with the translated text: {% block main %} <script> let TRANSLATION = {% trans "my text" %} </script> {% endblock %} So after Django translates the text in my index template, my JavaScript file can take the translated text and append it using something like: element.innerHTML = TRANSLATION; I know this is a very dirty way of translating the text that JavaScript will use because some users won't need that text and in those cases I'll be wasting resources with variables that I won't be using. So the question is: What is the clean and correct way to translate text for external JavaScript files? -

I am creating a simple login form using tailwind.css. I want the form to take up the full height of the screen, but for some reason, it doesn't and leaves white space at the bottom: I don't understand why this is happening, but I think it has something to do with the second div, which has the lg:w-1/2 property. Here is my HTML code (I'm including all of it, just in case my issue has is being caused by another HTML element): <div class="" id="content"> <section class="relative bg-white overflow-hidden"> <div class=> <nav class="flex justify-between p-6 px-4" data-config-id="toggle-mobile" data-config-target=".navbar-menu" data-config-class="hidden" style="background-color: #2A3342 !important;"> <div class="flex justify-between items-center w-full"> <div class="w-1/2 xl:w-1/3"> <a class="block max-w-max" href="{% url 'home' %}"> <img class="h-8" src="https://i.ibb.co/LRCrLTF/Screenshot-2022-04-03-140946-removebg-preview.png" alt="LOGO" data-config-id="auto-img-1-2" style="transform: scale(2); padding-left: 30px"> </a> </div> <div class="w-1/2 xl:w-1/3"> <ul class="text-slate-400hidden xl:flex xl:justify-center"> <li class="mr-12"><a class="text-slate-400 font-medium hover:text-white transition ease-in-out delay-150" href="#" data-config-id="auto-txt-1-2" style=" font-size: 18px">About</a></li> <li class="mr-12"><a class=" text-slate-400 font-medium hover:text-white transition ease-in-out delay-150" href="{% url 'classes' %}" data-config-id="auto-txt-2-2" style=" font-size: 18px">Classes</a></li> <li class="mr-12"><a class=" hover:text-white font-medium text-slate-400 transition ease-in-out delay-150" href="{% url 'resources' %}" data-config-id="auto-txt-3-2" style=" font-size: 18px">Resources</a> </li> <li><a class=" hover:text-white font-medium text-slate-400 transition ease-in-out delay-150" href="#" data-config-id="auto-txt-4-2" style=" font-size: 18px" id = "responsivehide">Upcoming</a></li> </ul> …
