Static files are not being loaded correctly in the browser when I access my site
Problem Description: I'm trying to set up a directory structure in my Django project where the static folder is inside the user folder, which is in turn inside the templates folder. My intention is to have static files located close to the template files. However, I'm having difficulties getting Django to properly serve static files from this directory structure. Directory Structure: project/ ├── templates/ │ └── user/ │ ├── index.html │ └── static/ │ └── css/ │ └── main.css └── ... Additional Details: I've configured STATIC_URL in settings.py: STATICFILES_DIRS = [os.path.join(BASE_DIR,'/templates/user/static/')] STATIC_URL = '/static/' In my index.html file, I'm using the <link rel="stylesheet" href="{% static 'css/main.css' %}"> tag to reference static files. Issue Faced: Despite adjusting the settings, I'm unable to make Django serve static files properly from this specific directory structure. I've tried different configurations, such as changing STATIC_URL, but I still haven't succeeded. Any help would be greatly appreciated. -
Wagtail always uses default site for URLs
I am using the Django site framework with wagtail. Wagtail correctly gives me the settings I specified for each site. I as of now have 2 sites registered: 127.0.0.1 172.1.16.155 So, when I visit 127.0.0.1, I get all the site settings for 127.0.0.1, and vice versa. The issue is, I have 172.1.16.155 as my default site. When I navigate to a URL from 127.0.0.1, (example: 127.0.0.1/home/) it will go to 172.1.16.1 (172.1.16.155/home/), and the same thing the other way around if I set the default site to the loopback addr. I have tried using both page.full_url and page.url, but to no avail. I have tried adding http://127.0.0.1 to the site settings (though I know this is incorrect), also to no avail. Some possibly relevant Django settings: # SECURITY WARNING: keep the secret key used in production secret!

Isolating User Sessions for AWS Credentials in a Django-Kubernetes Web Application
I am currently developing a web application using Django that takes AWS credentials from the user and retrieves data from their specific AWS bucket. Each user has distinct AWS credentials and accesses different AWS buckets. The AWS credentials are used temporarily for the duration of the user session until logout. The application is set up such that it uses the AWS credentials to retrieve data through Python code, using these credentials for the duration of the session. The goal is to deploy this application on a Kubernetes cluster. Now, I am facing a scenario where multiple users could be accessing the application simultaneously. Here are the specifics: User 1 logs in to the application on Computer 1 using AWS Credentials 1. User 2 logs in to the application on Computer 2 using AWS Credentials 2. In the given scenario, it is crucial that User 1 only sees data from the AWS bucket associated with AWS Credentials 1, and User 2 only sees data from the AWS bucket associated with AWS Credentials 2. The data shown to one user should not be mixed up or reflected on the other user's screen, even upon page refreshes. My question is, how can I … -

UUID value as function argument - Uncaught SyntaxError
Good day dear Community! I have a simple JS function which takes an "id" as argument: <script> function deleteBl(id){ fetch('', { method: 'DELETE', headers: { 'X-CSRFToken': '{{ csrf_token }}' }, body: JSON.stringify({ 'id': id }), credentials: 'same-origin', }) } </script> and below Django template: {% for item in bl_query_set %} <tr> <th scope="row">{{ forloop.counter }}</th> <td>{{ item.bl_number }}</td> <td class="text-center">{{ item.cargo_name }}</td> <td>{{ item.cargo_quantity }} {{ item.cargo_measurement }}</td> <td> <a onclick="deleteBl({{ item.id }})"> <i class="fas fa-trash-alt"></i> </a> </td> </tr> {% endfor %} and it works pretty well, there are no any console errors if I use default Id as primary key. But I need to use UUID as a primary key and in that case I get an error: "Uncaught SyntaxError: Invalid or unexpected token". See below screenshot please So, how I can resolve mentioned issue? Thanks for any help in advance! -

Django HttpResponse takes much CPU time
Django takes way too much CPU time to send response to localhost using the development server (same thing happens with gunicorn but a worker timeout occurs). The response size shouldn't be more than 15KB so the content size isn't the problem. I am using a virtual environment (venv) on Ubuntu 22.04.

TailwindCSS grid-columns don't apply in Django Template
I'm using TailwindCSS in a Django template. I want to display all elements of a form in 3 columns, but somehow they all get displayed within one column.

How to get a react page in my django backend to send it in mail
I have a backend server using Django framework and frontend using React.js I have a page that shows some statistics and wish to export this page in my backend so that I can send it in mail for recipients every interval (15 minutes, 30 minutes..). The page changes every minute so that I can't upload the page as pdf once in backend and use it later. I found that I can use headless browser to make a request to frontend to get the page but I have concerns about this appoach.. Or how heavy it is to add a headless browser in my backend server. And I don't want to recreate the page again in Django using templates because I won't be able to copy the design and also it is extra development time and duplicated code. I can see that those who use server side rendering can acheive this task easily while the page is renedered in backend.. that means they can use the page to send it in mail as pdf or to send it as a response to clients. I expect to have a good performance and wish to have some overview if this task already exist … -
How to get values with a different "path" in the database?
I want to get values from a table (the end goal is to create a dataframe out of a queryset). Those values depend on a form submitted by a user. Here is a simplified snippet of my models: class Report_Sample(models.Model): assay = models.CharField(max_length=50) samtools_data = models.ForeignKey( "Samtools_data", on_delete=models.DO_NOTHING, blank=True, null=True ) picard = models.ForeignKey( "Picard", on_delete=models.DO_NOTHING, blank=True, null=True class Samtools_data(models.Model): total_passed = models.IntegerField(null=True) total_failed = models.IntegerField(null=True) class Picard(models.Model): sample = models.CharField(max_length=10) library = models.CharField(max_length=10) read_group = models.CharField(max_length=10) picard_hs_metrics = models.ForeignKey( "Picard_hs_metrics", on_delete=models.DO_NOTHING, blank=True, null=True ) class Picard_hs_metrics(models.Model): bait_set = models.CharField(max_length=10) bait_territory = models.FloatField() Using the form, the user can select a subset of Report_sample objects and a metric to look at. So let's say the user wants the Samtools total_passed field. I can do: subset_report_samples = Report_sample.objects.filter(whatever_filter_the_user_wanted) metric_filter = None for model in apps.get_models(): for field in model._meta.get_fields(): if field.name == metric: metric_filter = f"{model.__name__.lower()}__{metric}" break subset_report_samples.objects.values(metric_filter) If we want to access the Picard_hs_metrics table however this breaks because of the intermediary table Picard. I thought about using a try/except block using from django.core.exceptions import FieldError but it feels horrible to use. So i was wondering if there was a Django method to find that metric_filter string given the field … -
How to create models for quiz application in django?
I'm working on a quiz app in django. I don't really know how to create the models for that. Basically, I need a quiz in sometimes questions are 'multiple choice', but sometimes they are 'short answer'. models.py class Quiz(models.Model): question = models.CharField(max_length=200) opt1 = models.CharField(max_length=100, null=True) opt2 = models.CharField(max_length=100, null=True) opt3 = models.CharField(max_length=100, null=True) opt4 = models.CharField(max_length=100, null=True) short_answer = models.CharField(max_length=100, null=True) def __str__(self): return self.question This is what I've already done. I don't know how will I understand if the current question is short answer or multiple choice. I think that if the short_answer field is empty, I can render the multiple choice. If it's not empty, I render short answer. Is it correct to do so? -

Django request.session.get() returns None across different view classes
I am working on a Django project and I'm encountering an issue with session variables. I set a session variable in one view, but when I try to access it in another view, it returns None.

Template variable for email in Django allauth socialaccount signup
