How to display a pdf in django and not let it download
I have a pdf file uploaded to the site (the Internet library and the pdf file of the book in it), how can I allow viewing this file while only on the site, and prohibit printing or downloading it. I will be grateful for tips or links to articles on how to do this. Everything I found on the Internet is not suitable, because the file can be downloaded and printed. I'm a beginner, so please don't laugh at my question. -
Static file error on Django windows server
I installed my project on Windows server, but it cannot see the static files. I tried many examples on the internet, but I could not solve the problem. please guide me on this Settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, "/static/") #STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') urls.py path('sitemap.xml', sitemap, {'sitemaps': sitemaps}, name='django.contrib.sitemaps.views.sitemap'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) + static(settings.MEDIA_URL, document_root=settings.STATIC_ROOT) if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) python manage.py collectstatic This is the result I get when I do it: You have requested to collect static files at the destination location as specified in your settings: C:\inetpub\vhosts\demo.com.tr\httpdocs\static This will overwrite existing files!

How to run Celery and Django web app simultaneously on Railway?
I'm trying to deploy a Django web application along with Celery for background task processing on Railway. I've configured my railway.json deployment file as follows: { "$schema": "https://railway.app/railway.schema.json", "build": { "builder": "NIXPACKS" }, "deploy": { "startCommand": "celery -A core worker --loglevel=INFO && python manage.py migrate && python manage.py collectstatic --noinput && gunicorn core.wsgi --timeout 60", "numReplicas": null, "healthcheckPath": null, "healthcheckTimeout": null, "restartPolicyType": "ON_FAILURE", "restartPolicyMaxRetries": 10, "cronSchedule": null } } However, with this configuration, only Celery starts, and the Django web server (gunicorn) doesn't seem to run. How can I adjust my deployment configuration to ensure that both Celery and the Django web app start and run simultaneously? I've tried rearranging the startCommand, placing celery at the end, but it doesn't seem to work. Any guidance or best practices for configuring Celery and Django web app deployments on Railway would be greatly appreciated. Thank you! -

Dynamically add/remove DateFields in Django formset
I have a very specific problem which is related to the package django-bootstrap-datepicker-plus. In my Todo list application I want to have the possibility to have tasks pop up on a number of specific dates. I got my model set up, I got my form including a formset set up, and I even have a JavaScript that handles the dynamic add/remove procedure. The problem that I have is that the cloning process of my DateField somehow messes with the DatePicker divs - see the outcome in the last code block below. # model.py from django.db import models from datetime import time # Create your models here. class Task(models.Model): id = models.AutoField(primary_key=True) title = models.CharField(max_length=50, default="") description = models.CharField(max_length=500, default="") entry_date = models.DateTimeField(auto_now_add=True) last_updated = models.DateTimeField(auto_now=True) specific_dates = models.ManyToManyField('SpecificDate', blank=True) due_until = models.TimeField(auto_now_add=False, default=time(12, 0)) class SpecificDate(models.Model): todo = models.ForeignKey(Task, on_delete=models.CASCADE) date = models.DateField(auto_now_add=False, blank=True, null=True) class Meta: # ensure each specific date is unique per task unique_together = ('todo', 'date') # forms.py from bootstrap_datepicker_plus.widgets import DatePickerInput, TimePickerInput from django import forms from .models import Task, SpecificDate class TaskForm(forms.ModelForm): class Meta: model = Task fields = [ 'title', 'description', 'due_until', ] widgets = { 'due_until': TimePickerInput(options={'stepping': 5, 'format': 'HH:mm'}), 'description': forms.Textarea({'rows': … -

Python / Django deploy issue on Heroku

Challenge with Ordering Django Signals and Celery Tasks for Group Operations
I'm facing an issue in my Django project where the execution order of Django signals and Celery tasks is causing complications, particularly in managing group operations asynchronously. Specifically, when there's a change in group administrators triggering the update_group_admins signal, the create request task (create_group_async) should ideally be executed before the tasks for adding or removing group members (add_group_admins_async and remove_group_admins_async). However, despite my meticulous planning, the sequence of execution remains incorrect, leading to errors and inconsistencies in the system. To address this issue, I've attempted various approaches to reorder the tasks and signals within my codebase. My expectation was that by ensuring the correct sequence of execution, the create request task (create_group_async) would be processed before the tasks for adding or removing group members (add_group_admins_async and remove_group_admins_async). However, despite my efforts, the execution sequence remains erroneous, and I haven't been able to achieve the desired outcome. -
How to solve logout error when using Django-Jazzmin?
I hope you are doing fine! I have built a django project recently, and while searching for methods to customize the admin panel, I found Django-Jazzmin. It is working and cool and all that, but I have one single problem with it, whenever I try to logout from the admin page, it returns the error 405, a.k.a "method not allowed". I am working with the Django 5.0.2 framework. Did someone find the solution for this problem? I tried to go to "my-virtual_env\Lib\site-packages\jazzmin\templates\admin\base.html" and modify the logout block to : <form method="post" action="{% url 'admin:logout' %}"> {% csrf_token %} <button type="submit" class="dropdown-item"> <i class="fas fa-users mr-2"></i> {% trans 'Log out' %} </button> </form> but it didn't help! -
Django - How to use AJAX within a form
I'm trying to use AJAX for the first time as we have a Django project but a required feature is for one form to behave more like a react app or SPA so I'm trying to use AJAX to add that functionality. I have the following template for the page. It has a form to let the user select from a dropdown what their highest education is and should have a modal appear to let the user input a qualification at a time to be added to the database and displayed on the table. The issue is when the user fills out the modal and clicks submit it seem's to perform just a normal GET request as can be seen below rather than the API request to create qualifications from the modal. AJAX seemingly isn't intercepting the request.

Filebeat CPU throttle in kubernetes with django logging
I have a simple Django API served with gunicorn on a Kubernetes cluster. And after long time of running the pod seems to CPU throttle. So I tried to investigate, I used Lucost to swarm my API of requests to see how it handles a unsual amount of requests. Here is a recap of normal activity of the API: 60 requests per hour 10 lines of log per request 600 lines of logs per hour So it's not an intensive requested API. Internally the API will check the body and make a request to CosmosDB server to retreive some data and then format it to send it back to the caller. Less than 200ms requets with very few memory needed. When doing a swarm with locust, I see that the cpu throttles and when using top command in the pod, I see that filebeat uses 40-60% of the cpu. While in normal activity it stays at 0.1-0.5% CPU. I kill -9 the PID of the filebeat, did the same swarm, and everything was smooth. I thought that my log file was too big and filebeat had issue with reading the file. Here is how my django logger is defined: "app_json_file": … -

A lightweight approach to processing Django Queryset data
I am looking for a optimal way to perform simple data processing from Django Queryset. I would like to not need to install libraries with high volumes like Pandas or numpy. The number of rows in Queryset should not exceed 2000. The idea is to perform basic functions such as x1, x2, x3 below. I want to avoid a separate database query for each of them so I'm thinking to get all this data once from the database, convert it to a standard data structure and calculate the results. Queryset Sample: T1_id T2_id T1_value T2_value 1 2 2 0 3 5 0 0 4 1 1 1 2 7 0 3 Pandas code equivalents: data = [[1, 2, 2, 0], [3, 5, 0, 0], [4, 1, 1, 1], [2, 7, 0, 3]] df = pd.DataFrame(data, columns=['T1_id', 'T2_id', 'T1_value', 'T2_value']) x1 = df[df['T1_id'] == 1]['T1_value'].mean() # Mean of T1_value from rows where T1_id == 1 x2 = df[df['T1_id'] == 1]['T2_value'].sum() # Sum of T2_value from rows where T1_id == 1 x3 = len(df[df['T1_id'] == 1]) # Number of rows where T1_id == 1 -
Django application deployed on Railway.app experiencing repeated worker timeouts and SIGKILL signals
I have deployed a Django application on Railway.app, utilizing Gunicorn 21.2.0 as the WSGI server. However, I'm encountering a persistent issue where the workers are timing out and subsequently being terminated with a SIGKILL signal. Here's a snippet of the logs: [2024-02-13 07:26:54 +0000] [7] [CRITICAL] WORKER TIMEOUT (pid:22) [2024-02-13 07:26:55 +0000] [7] [ERROR] Worker (pid:22) was sent SIGKILL! Perhaps out of memory? ...

This pattern repeats consistently, with workers timing out and subsequently being killed. The application appears to be experiencing memory issues, as suggested by the error message. I've tried adjusting various configurations, such as increasing worker timeouts and tweaking memory allocation, but the problem persists. My suspicion is that the application may be exceeding the memory limits imposed by the hosting environment. Has anyone encountered similar issues while deploying Django applications on Railway.app? Any insights or suggestions on how to diagnose and resolve this problem would be greatly appreciated. Thank you! -
