Django model not Associating with another model object
I am using Django to create an application where I have an Employee model that needs to be associated with a Company model. I am able to associate the User model with the Employee model correctly, but I am having trouble associating the Company object with the Employee object. My view: from django.shortcuts import render from django.http import HttpResponse from company.models import Company from .models import Employee from .forms import UserForm, CompanyForm from django.contrib.auth.models import User import random, string from django.db import IntegrityError def new(request): # Initialize forms user_form = UserForm(request.POST or None) company_form = CompanyForm(request.POST or None) # Check if the request is a POST request if request.method == 'POST': # Check if both forms are valid if user_form.is_valid() and company_form.is_valid(): email = user_form.cleaned_data['email'] # Check if a user with this email already exists try: user = User.objects.get(email=email) user_created = False except User.DoesNotExist: user = User(username=email, email=email) random_password = User.objects.make_random_password() user.set_password(random_password) user.save() user_created = True # Save the company form data company = company_form.save() # Check if an Employee already exists for this user try: employee = Employee.objects.get(user=user) employee_created = False except Employee.DoesNotExist: employee = Employee(user=user, company=company) employee.save() employee_created = True # Return appropriate response based on what was … -

celery redis key unacked issue
I am using the Glitchtip service, which employs Celery to initiate worker processes for job processing. This setup involves a combination of Celery and Redis, where Redis serves as a message broker. Upon sending a substantial number of requests, I've noticed a spike in the Redis key named "unacked," which eventually causes Redis to run out of memory. In my environment configuration, I have set the following parameters: CELERY_ACKS_ON_FAILURE_OR_TIMEOUT is set to False. CELERY_ACKS_LATE is set to True. I'm wondering if there are any additional environment parameters that I should consider setting in order to better control the processing rate. Your assistance in this matter is greatly appreciated.

Django Polymorphic behaviour (Custom ForeignKey) without using GenericForeignKey
I'm working with a legacy DB that has fields like edited_by_type, and edited_by_id in many tables. This is basically a polymorphic relation for RubyOnRails persons. This represents a FK relation to multiple models using combinations of these two fields. for example, the value of edited_by_type can be either user, admin, or client. These are 3 different tables. so now you can guess that it's basically a unique constraint of edited_by_type, and edited_by_id together, where edited_by_type is used to determine the type of person (table) and then query that table using edited_by_id. I have a fairly good understanding of Django's GenericFK field that uses the contentType table internally. but since this is a legacy DB and I don't want to use the ContentType table at all it requires creating migrations and entries in the contenttype table. What I'm looking for is a customFk or (even customGenericFK) solution that somehow manages this and allows us to query the db as easily as we can. e.g something like the below (open to any other approach that doesn't involve creating a CustomFK). here is what I've tried so far. class CustomFK(models.ForeignKey): def __init__(self, fk_models, on_delete, **kwargs): for model in fk_models: super().__init__(to=model, on_delete=on_delete, **kwargs) # … -

Django form field feed with javascript produced list
I'm learning Django through a recipe posting website, in the recipe form I want to pass an ingredient list that is created with a java script function on the fly. I have two buttons, one to create the list, and the final submit button when the recipe form is ready. The problem is that every time the ingredients "adding ingredient button" is clicked, the form is submitted, since it is not valid it resets the whole form. How can I integrate the java script without submitting the form? I've tried many solutions that I've seen everywhere to no avail, so any help is welcome. Model. class Recipe(models.Model): """Represents the whole recipe description""" recipe_name = models.CharField(max_length=100, default=None) user_name = models.ForeignKey(User, on_delete=models.DO_NOTHING) description = models.TextField(max_length=500, help_text='Enter a brief description of the recipe') ingredients = models.TextField(max_length=1000, help_text='enter all the ingredients with quantities') cooking_time = models.CharField(max_length=50) preparation = models.TextField(max_length=3000, help_text='Enter the steps to prepare the recipe') date = models.DateField(auto_now_add=True) script. class Recipe(models.Model): """Represents the whole recipe description""" recipe_name = models.CharField(max_length=100, default=None) user_name = models.ForeignKey(User, on_delete=models.DO_NOTHING) description = models.TextField(max_length=500, help_text='Enter a brief description of the recipe') ingredients = models.TextField(max_length=1000, help_text='enter all the ingredients with quantities') cooking_time = models.CharField(max_length=50) preparation = models.TextField(max_length=3000, help_text='Enter the steps to … -
Django blog UserProfile model
I am creating a Django blog app and I already set up a Post and Comment model both linked with the built in Django User model via these fields below: POST MODEL writer = models.ForeignKey( User, on_delete=models.CASCADE, related_name="blogs" ) COMMENT MODEL writer = models.ForeignKey( User, on_delete=models.CASCADE, related_name='user_comments') If I add a UserProfile model to this blog app, would I need to change the foreign key relationship in my post model to this: writer = models.ForeignKey( UserProfile, on_delete=models.CASCADE, related_name="blogs" ) Thanks P.S. I want only admin users to have profiles and to be able to click on their profiles to view the posts they have created. Regular users do not have the ability to create posts. They can only comment and like the posts. -
Urls in CSS files not getting signed through django-storages
For example, my css code has this image file: background: url('/static/studyspot5/images/shapes/footer_sass.png'); And it does not render on my AWS site I have the following relevant code in my settings.py: if USE_S3: STATICFILES_LOCATION = 'static' MEDIAFILES_LOCATION = 'media' MEDIA_URL = f'https://{CLOUDFRONT_DOMAIN}/{MEDIAFILES_LOCATION}/' MEDIA_ROOT = f'https://{AWS_S3_CUSTOM_DOMAIN}/static/{MEDIAFILES_LOCATION}/' STATIC_URL = 'https://%s/%s/' % (CLOUDFRONT_DOMAIN,STATICFILES_LOCATION) STATIC_ROOT = 'https://%s/%s/static/' % (AWS_S3_CUSTOM_DOMAIN,STATICFILES_LOCATION) STORAGES = { "default": {"BACKEND": 'custom_storages.MediaStorage'}, "staticfiles": {"BACKEND": 'custom_storages.StaticStorage'}, "OPTIONS": { "bucket_name": AWS_STORAGE_BUCKET_NAME, "region_name": AWS_S3_REGION_NAME, # "verify": AWS_S3_VERIFY, "signature_version": AWS_S3_SIGNATURE_VERSION, "cloudfront_key_id": AWS_CLOUDFRONT_KEY_ID, "cloudfront_key": AWS_CLOUDFRONT_KEY, "custom_domain": CLOUDFRONT_DOMAIN, }, } The CSS file (and all other static content) is served as a signed URL just fine, e.g. using the following code: <link rel="stylesheet" href="{% static 'studyspot5/css/style.css' %}"> But for those urls inside of CSS files, it will only pass the url of the file, without signing it (no parameters). Here is the resulting request headers. Note the referer URL is signed, but the darn background image from the CSS is not! -

Django Email Configuration Issue: ConnectionRefusedError [WinError 10061]
Question: I'm encountering a ConnectionRefusedError in my Django project when trying to send emails.

Django dev server only allowing 1 user concurrently? Local host allows more
The problem that I am having is solely on my development server when two users execute POST requests back to my server concurrently (or at any point), in doing so one of the two users is logged off. I am wondering if anyone has any thoughts as to what would cause multiple users to not be able to interact with the server? The error occurs in this situation: I open two browsers on the same machine or different and go to my dev URL. I log into two different user accounts (held in my database) on each of the browsers. I am able to navigate fine on both to get to a spot to submit a POST request. I submit a basic HTML form for each of the users. One of the users (generally the second to request), is logged out and sent back to the login page when the POST request returns to that user. The other users post request is fine but he is then also forced to logout. I am building an app in django. I am using the session engine SESSION_ENGINE='django.contrib.sessions.backends.signed_cookies'. So far I thought that it was a database connectivity or cookie issue but that … -

Cannot send message from Django to Telegram (telegram-send)
I want to send a message from Django to Telegram bot when a user submits a form. Following this short instruction (in Russian) I created a Telegram bot with a certain name, got an API token, installed telegram-send: pip install telegram-send then configured it: telegram-send --configure On request of the program I provided the API token and got a numerical password, which I entered in the Telegram bot channel and got a success message, which says that I can write to the channel with telegram_send. It really works! When I type directly in the terminal telegram-send "Hello!" I see my message popping in the bot channel. But then I stuck, trying to send message from one of my views. According to the instruction, I should import the package in my views.py module: import telegram_send and then use it somewhere in views and functions: telegram_send.send(messages=["Hello!"]) I tried to insert this code in different parts of my ListView, but cound't make it work. For example, I tried to add it to standard method get_context_data, which should be implemented each time the corresponding web page is requested class PropertyListView(ListView): def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) ... telegram_send.send(messages=["Hello!"]) return context But the message does … -
Django Admin autocomplete field selector unidesirable behavior
I have an enterprise project based in Django which is stuck in version 3.1.7 due to unexpected behavior of autocomplete field admin selector. In former versions, when you click in the combobox, the text input editor is autoselected so once you click the first time, you can automatically start writing for searching in the list of fereign key values. I tried to update to newer version of Django, but certain users have complained that now they have to make the extra step of clicking in the text input editor, because it does no longer automatically write once you click the combobox. Ever if this is a minor nuance for computer versed users, workshop users (who lest's be honest, many of them are quite dumb with tech stuff) complain because it does not longer does the usual "easier" stuff and have to be more careful. Anyway, I do not understand why the change of this behavior in newer versions, it is a loss even if it is a small one. Is there any way to force the admin template component to work as it preivously did? -

Set a list of available times in jquery timepicker
I am trying to set a list of predefined times in a jQuery timepicker. It should run from 10am to 12 midnight. I am also trying to highlight certain times that there is no availability.
