Django REST Framework: Strange behaviour in unit tests

Django Template request.GET.value don't work
I need to set selected="selected" for a select field. <form action="{% url 'books:book_detail' book.pk %}" method="get"> {% csrf_token %} <select name="country"> {% for shop_country in shop_countries_list %} {% if request.GET.country == shop_country.pk %} <option value="{{ shop_country.pk }}" selected="selected">{{ shop_country.name }}</option> {% else %} <option value="{{ shop_country.pk }}">{{ shop_country.name }}</option> {% endif %} {% endfor %} </select> <button class="button" type="submit">Search</button> </form> But it's not working. I think that request.GET.country inside the if statement is null or empty. But if I to put request.GET.country in some other place of my code like this: {{ request.GET.country }} - it give the correct value. So the question is why it doesn't give any value inside the if statement? -

On Raw HTML, website looks as I intend it. But on Django, there is some blank space created during the for loop
<div id="Project" class="bg-white fnt-white brdr project-div "> <div class="float-left image-for-project-container brdr"> <img src="{% static './Images/manworking.webp' %}" alt="manworking" height="630px"> </div> {% for project in project_details %} <div class=" project-container inline-block "> <h2 class="text-center fnt-black head-portfolio"> {{project.project_name}} </h2> <br> <br> <p class="margin-auto txt-portfolio roboto hover-orange fnt-black"> {{project.project_details}} </p> <br> <a href="#" class="buttons read-more fnt-black">Read More</a> </div> </div> Issue: The project container when receiving dynamic entries from Django model, creates multiple project containers as executed by the forloop. However, as evident from the image attached, as each project container is created, it is creating an unwanted upward indentation or margin successively. What am I doing wrong? This is the HTML code. I do not think there is any requirement for my CSS stylesheet as when I view the HTML file without Django, it's absolutely alright. I have also attached an image to show the space that is being created. In case the Imgur is not being shown here is the link (https://i.stack.imgur.com/EnUUG.png). -

Django production multiple post request
I have a question regarding the multiple handling of django. I have read the answers to this question How does Django handle multiple requests?. I wrote a django application and it is deployed which takes POST request and do some string splitting in the background and returns the results on the side. My problem would be that if two users sent two POST request (from two different clients), then the process is slowed down dramatically and I only see one process in my Apache server. I am not sure whether Django handles just a request at a time and I could not distribute the process properly. Is a asynchronical restructuring necessary? Thanks -

django and mypy with apps in a subfolder
We have a Django project with the following setup: We have our apps in an apps folder. We added all those apps to the python path at settings.py level. We then can refer and import these apps like so: from apps.booking.models import Booking # or from booking.models import Booking Now, we want to use mypy for type checking purposes. The issue is that mypy does not recognize the import from booking.models import Booking and complains about missing stubs for this module. This make the typing very unreliable and not very useful as Booking is then typed as Any. It works fine with an import as follow however from apps.booking.models import Booking Is there a way to make mypy understand the path without the prefix apps. ? I tried to use mypy_path = $MYPY_CONFIG_FILE_DIR/apps in mypy.ini but without any success... -
