How to format (succinctly) a date when returning django validation?
For a string type foo, you can write print('The value is %s' % foo) But how do you do this if foo is a datetime? from datetime import date foo = date.today() print('The value is %?' % foo) i.e. what do you write in place of ? to format as a date; preferably dd-mmm-yyyy say? Here is what I'm really trying to do. In django, I'm validating a date: if start_date < date.today(): raise ValidationError( _('%(start_date)s must be on or after today.'), params={'start_date': start_date}, ) But I need something better than s -

Handle IntegrityError on signup for allauth Django
I'm using Django allauth for google user signup and login. Now I wanted to have unique email address for each user that tries to signup be it through google or normal django signup.

Gunicorn - ModuleNotFound crispy_forms (But is installed)
I am trying to setup Crispy Forms on my Django environment. I have installed Crispy Forms using pip3 install --user django_crispy_forms and I have added the 'crispy_forms' to the INSTALLED APPS within my settings.py file. Although, I am unable to boot up my gunicorn service file, as an error is displaying "ModuleNotFound Error crispy_forms" Just to ensure that Crispy Forms is installed, I tried to rerun the installation to which I receive a message "requirements are already satisfied". Any ideas to what could be causing this behaviour? Edit: If I remove 'crispy_forms' from the INSTALLED APPS area, my gunicorn service boots up perfectly fine. Thanks! -
Django + Bootstrap collapsed table front-end issue?
I have been trying to figure out a front-end issue I've been on for a few days. I am using Django + Bootstrap collapsed accordion. What I am trying to do is completely hide a div, and all spacing until the collapsable button is clicked (eyeball). For some reason it's throwing a couple weird front-end issues like below. Basically what the collapsed div does, is show details if the user provides them which are new table rows. But on page load it shows all of this extra spacing where the collapsed rows are, and also throws some odd border issues? The first entry with the issue is an instance where a user has provided Address Phone Position Concern This is the HTML I have in place as of now, <style> .hiddenRow { border-top-style: hidden; border-bottom-style: hidden; } </style> <div class="table-responsive"> <table class="table small"> <thead> <tr> <th></th> <th>Entry Date</th> <th>Employee First Name</th> <th>Employee Last Name</th> </tr> </thead> {% for employee_entry in employee_entries %} <tbody> <tr data-toggle="collapse" class="accordion-toggle" data-target=".employee-entry-{{ employee_entry.id }}"> <td><button><span class="glyphicon glyphicon-eye-open"></span></button></td> <td>{{ employee_entry.created_at|date:'M d, Y' }}</td> {% if employee_entry.first_name %} <td>{{ employee_entry.first_name }}</td> {% else %} <td></td> {% endif %} {% if employee_entry.last_name %} <td>{{ employee_entry.last_name }}</td> {% else … -

How to test image upload on Django Rest Framework
i'm on a struggle. The problem is with the unit testing ("test.py"), and i figured out how to upload images with tempfile and PIL, but those temporary images never get deleted. I think about making a temporary dir and then, with os.remove, delete that temp_dir, but the images upload on different media directorys dependings on the model, so i really don't know how to post temp_images and then delete them. This is my models.py class Noticia(models.Model): ... img = models.ImageField(upload_to="noticias", storage=OverwriteStorage(), default="noticias/tanque_arma3.jpg") ... test.py def temporary_image(): import tempfile from PIL import Image image = Image.new('RGB', (100, 100)) tmp_file = tempfile.NamedTemporaryFile(suffix='.jpg', prefix="test_img_") image.save(tmp_file, 'jpeg') tmp_file.seek(0) return tmp_file class NoticiaTest(APITestCase): def setUp(self): ... url = reverse('api:noticia-create') data = {'usuario': usuario.pk, "titulo":"test", "subtitulo":"test", "descripcion":"test", "img": temporary_image()} response = client.post(url, data,format="multipart") ... So, to summarize, the question is, ¿How can i delete a temporary file from different directories, taking into account that those files strictly have to be upload on those directorys? -

Handling complex computation on a web app involving data from a database
Just some background. This question is to help my team and I make a decision on how to handle an app we are working on. Currently the application is hosted locally in ASP.NET C# and the complex calculations that are done are handled in SQL as a stored procedure. The data is pulled into queries and the server will handle all the calculations and return a recordset which is written to a table and the front end can access that table. So moving forward, we're thinking of moving the application to the web with Django and deciding how to handle the server side of things. So what we really wanted to understand is, how do others handle situations like these? Do we continue with the same idea and build a SQL server and do the same thing or is there a better way to solve this problem? We want to the user to be able to kick the calculations off and do other things while it runs in the background. The user shouldn't have to sit on the page because these calculation can take an hour or more depending on the complexity. We'd appreciate the thought and ideas. Thank you … -

Redis wrong version number
I am very new to deploying my Django site on Heroku. I was trying to get Celery to work (as my Django has long processes). I was following a tutorial on how to set up Redis on Heroku. The issue now is that I am getting this error: Error accepting a client connection: error:1408F10B:SSL routines:ssl3_get_record:wrong version number (conn: fd=11) There are not many solutions online, I only kind of understand that I will need to downgrade this somehow, any suggestions on how to overcome this problem?

Django Abstract User - how to implement it and adapt to current signal
I don't have the standard Django User model to rely on, I don't know how to refer to the instance below. Before changing to the Abstract User Model I would refer to (user=instance). I was attempting to adapt a functioning e-commerce site by removing/including aspects, one of these adaptations was a Custom User model. Could it be true that I wouldn't need the "create_or_update_user_profile" function anymore since User is now the model that is used as the AUTH_USER_MODEL? When attempting to log in as admin, this error fires: File "/workspace/Project-Saasy/profiles/models.py", line 48, in create_or_update_user_profile instance.userprofile.save() AttributeError: 'User' object has no attribute 'userprofile' So I wondering either how to add the attribute to the 'User' object, or if there another way around all of this models.py from django.db import models from django.contrib.auth.models import AbstractUser from django.db.models.signals import post_save from django.conf import settings from django.dispatch import receiver class User(AbstractUser): """ A user profile model for maintaining default delivery information and order history """ is_volunteer = models.BooleanField(default=False) is_organisation = models.BooleanField(default=False) default_phone_number = models.CharField(max_length=20, null=True, blank=True) default_street_address1 = models.CharField(max_length=80, null=True, blank=True) default_street_address2 = models.CharField(max_length=80, null=True, blank=True) default_town_or_city = models.CharField(max_length=40, null=True, blank=True) default_county = models.CharField(max_length=80, null=True, blank=True) default_postcode = models.CharField(max_length=20, null=True, blank=True) class Volunteer(models.Model): user … -
How to get last element in a ForeignKey relation?
To describe my problem I will use basic models : class Chatroom(Model): date_created = models.DateTimeField(auto_now_add=True) name = models.CharField(max_length=3000) class Message(Model): date_created = models.DateTimeField(auto_now_add=True) text = models.CharField(max_length=3000) room = models.ForeignKey( Chatroom, on_delete=models.CASCADE, related_name='messages' ) I want to display every last messages sent to a room ordered by date of creation. In practice, the user connect to the page and he can see the messages ordered by date, but only the last message of each room. Example : in the database we have: rooms = [RoomA, RoomB] messages = [ { text: 'firstA', date_created: 01/05/21, room: RoomA }, { text: 'secondA', date_created: 03/05/21, room: RoomA }, { text: 'firstB', date_created: 02/05/21, room: RoomB }, { text: 'secondB', date_created: 06/05/21, room: RoomB }, ] As a result of my queryset, I want to get last messages of each room, meaning messages [secondB, secondA]. Currently I am doing the following : messages_uids = Message.objects \ .order_by('room_id') \ .distinct('room_id') \ .values_list('pk', flat=True) queryset = Message.objects \ .filter(pk__in=messages_uids) \ .order_by('-date_created') return queryset I have only one message per room (good point), messages are ordered by date_created (good point), but I do not have the last message of each room.

DisabledBackend Error with every second reload with Django, Celery and RabbitMQ
I am using django, celery and RabbitMQ for a webserver. On my development server everything works fine.

What to use instead of DO_NOTHING to only delete one field?
I want to link two models like this class t_data(models.Model): receiver = models.TextField() file_desc = models.TextField() file = models.FileField(upload_to='files') another model : class transaction_detail(models.Model): transaction_id = models.ForeignKey( t_data, on_delete=models.DO_NOTHING, ) sender=models.TextField() receiver = models.TextField() *yes i am using DO_NOTHING and i have read that it is wrong to use it. But it is not working. now when a user tries to delete his file, The t_data object should be deleted but the transaction_details should not change.There is nothing specific on my view for deleting objects. Yet, simple example would be def delete_request(request,id): requested = t_data.objects.get(id=id) requested.delete() return HttpResponseRedirect('/requests') When I try to delete the t_data object it throws an Integrity Error. How to solve it? Or what to use in place of DO_NOTHING? We can also use OneToOneField if you want to solve this problem. Thank you :) -

Django : Run task in background immediately
Similarly to this question, I don't understand how the django-background-tasks module works. What I want is to have a button which would start a task in background so it doesn't block the front. The task has to be run as soon as the click occurs. Reading the docs I thought that I only had to define my task as a function preceded by the decorator @background(schedule=1) then calling the function would start the task one second after the click handler was run. Calling notify_user as normal will schedule the original function to be run 60 seconds from now: However this is not what happens. What happens is that a new task is created after each click (I could understand that by requesting the background_task database thanks to this answer) but none ever runs. The command python manage.py process_tasks seems to run one task defined previously before stopping. If no task has been defined, then it waits for a task to be defined for up to duration seconds (specified when running the command). This behavior is not what I expected while reading the documentation. duration - Run task for this many seconds (0 or less to run forever) - default is … -
