Django per-site cache is not working properly
I'm facing some difficulties caching my website (JS, CSS, fonts, images). When I use lighthouse, I got these results [Cache TTL are all None] while I'm already applying the per-site caching as described in Django documentation. `MIDDLEWARE = [ ... 'django.middleware.cache.UpdateCacheMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.cache.FetchFromCacheMiddleware', ... ] CACHE_MIDDLEWARE_ALIAS = 'default' CACHE_MIDDLEWARE_SECONDS = 2 592 000 # for 1 month ` Is there any help in order to well cache the website?

Only the first Django site to be loaded works
I recently submitted a problem to stackoverflow titled Django infinite loading after multiple requests on apache using mod_wsgi. Anyways, I have recently changed a lot of that code and now I have a new problem. The first Django website I request works, however, the second one points to the first one I loaded and gives the response DisallowedHost because obviously it is trying to access that Django application with a different domain name. I obviously want it to do that it should do so if anyone can help me that would be great. Here is all my code.

What happens line by line after I register a model in django
I'm new to programming and I don't really understand what's going on line by line in the code For example: to register a model in Django, we can register the class “class Genre(models.Model)” and specify only one field, for example “models.Charfield.” In turn, the parent class “Model(metaclass=ModelBase) (django.db.models.base)” contains about 50 methods. Most of them are private Questions: Were these 50 methods called when I registered the model? If “yes”, which line of code is responsible for this call? Or which principle of OOP? Could you recommend any article or book to delve into this topic? Thanks in advance! -

Custom template tag wont assign to {% with %} context
I'm in need of a custom tag where multiple keyword arguments can be passed in for the purpose of creating an unique id for a given object instance. Whatever string the tag returns it assigns the string as a context variable to the included template. Yet the id context variable remains empty. In this case, the ids for the SVG elements only return the hardcoded strings upvote_ and downvote_. How can I fix this so that the id context variable is interpolated into the string of the SVG id attributes? An example being: upvote_queston101 {% for answer in question.answers.all %} {% include "./posted.html" with post=answer id=set_id question=question.id answer=answer.id %} {% endfor %} <div class="rating_box"> <div class="vote"> <svg id="upvote_{{ id }}" class="vote_button"> </svg> <p>{{ post.score }}</p> <svg id="downvote_{{ id }}" class="vote_button"> </svg> </div> <p class="post_body_content">{{ post.body }}</p> </div> from django import template register = template.Library() @register.simple_tag def set_id(*args, **kwargs): if kwargs['question'] and kwargs['answer']: q_id, a_id = kwargs['question'], kwargs['answer'] return f"question{q_id}_answer{a_id}" q_id = kwargs['question'] return f"question{q_id}" -
Flutter Web on Firebase hosting refused to make API Calls
I have a Flutter Web application that I have deployed on Firebase Hosting. I have a Django backend that I have deployed on an EC2 instance and is running on http. I have CORS enabled in the backend, tried accessing endpoints via browsers and it works just fine. But, when I try to make the same call using FlutterWeb, it fails. And error type of blocked:mixed content appears. (See image below) I want to call those HTTP endpoints and I don't want an SSL certificate mess because this is just a college project. How do I fix this? I am using Dio on Flutter Web to make requests. What would be causing this problem? -

Getting top 3 most enrolled course by students
I am building a website where an instructor can create courses and students can enroll the courses. I wanted to display top 3 most enrolled courses/popular courses. I tried to filter the courses that the instructor has, find the number of students that has enrolled to the courses and ordered them by descending which means it will display from highest to lowest number of enrolled students per course.

Formatting Django test output
I would like to format the output of test output in my Django app because I have a lot of tests and at this point there is so much output that it is unreadable. I have read Django docs on logging and I understand that I would need to configure LOGGING dict in my settings and use Loggers, Handlers, and Formatters, along with Python's native logging lib doing majority of heavy lifting. The problem is that I don't know where to begin. Here is what I would like to achieve in terms of output: TOTAL tests run: 123 Failed: 4 Skipped: 5 Passed: 114 APP2 tests run: 34 Failed: 0 Skipped: 1 Passed: 114 APP3 tests run: 67 Failed: 5 Skipped: 0 Passed: 62 According to Django docs logging is fairly customizable with something like this (taken from official docs, closer to the bottom of the page): LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': '{levelname} {asctime} {module} {process:d} {thread:d} {message}', 'style': '{', }, 'simple': { 'format': '{levelname} {message}', 'style': '{', }, }, 'filters': { 'special': { '()': 'project.logging.SpecialFilter', 'foo': 'bar', }, 'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', }, }, 'handlers': { 'console': { 'level': 'INFO', 'filters': ['require_debug_true'], … -

How to use row_factory with a non-default Sqlite database in Django
