Is it possible to find out why Heroku cannot find Django templates?
I have tried everything that I've found before and nothing helped me. I deployed my project on Heroku and I get this error. My templates in other apps begin with {% extends 'base/base.html' %} This template is located in a base templates folder(you can see it below) But I got this error: settings.py BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'templates') ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] import dj_database_url DATABASES['default'] = dj_database_url.config(conn_max_age=600, ssl_require=True) STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static') ] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' MEDIA_URL = "/media/" MEDIA_ROOT = os.path.join(BASE_DIR, 'media') import django_heroku django_heroku.settings(locals()) I don't know why Heroku cannot find my base template. If I remove extends, it'll render an app template, but without styles. But it'll render and it's the most important. -

Django How to pass variable from a view to a form view
I have two models. One is project and another is todo. The todo model has a foreign key that is the related project's id. I have a template that displays the individual project and generates a link to a form to add a todo list. How do I pass the project id to the todo form? I guess I could simply pass the project id in the URL but is that the best way? My current views.py class CompanyProjectsDetailView(DetailView): model = Project id = Project.objects.only('id') template_name = 'company_accounts/project_detail.html' class TodoCreateView(CreateView): model = ProjectTodo template_name = 'company_accounts/add_todo.html' fields = ['title', 'notes', 'status'] -

Is it possible to filter django Many-To-Many QuerySet fields by checking if they're intersection is not empty?
Doing an exercise about creating a Django service that given a certain job returns the best candidates. Sure it's a Machine Learning problem, and the scoring algorithm here is very simple. Frankly, this is the first time I'm using Django and I'm having some issues to filter out objects from one of the models. This is my model class: from django.db import models class Skill(models.Model): name = models.CharField(max_length=100) def __str__(self) -> str: return f'Skill name: {self.name}' class Candidate(models.Model): title = models.CharField(max_length=100) name = models.CharField(max_length=100, default='') skills = models.ManyToManyField(Skill) def __str__(self) -> str: return f'Name: {self.name}, title: {self.title}' class Job(models.Model): title = models.CharField(max_length=100) skills = models.ManyToManyField(Skill) def __str__(self) -> str: return f'title: {self.title}' Given a job name, I would first like to filter by the skills i.e., go over the given Candidates and filter out the ones that don't have a mutual skill with the given job. In a more mathematical approach - the job_skills_set and the candidate_skills_set intersection is not empty. Something likes this: (I mixed Python syntax) Candidate.objects.filter(len(set.intersection(set(skills), set(job.skills))) > 0) Is there a way I can do that in Django? Tried multiple ways and did not succeed. Thanks in advance! -

Catch-22 when trying to create two-way Django relationship
I want to allow my users to be able to have a selection of avatars and (crucially) force every user to have one which will be used as the main one. With that in mind, I've got the following (slightly cut down) models:- class Avatar(models.Model): user = models.ForeignKey(User, related_name="avatars", on_delete=models.CASCADE) image = models.ImageField() class User(AbstractUser): avatar = models.OneToOneField(Avatar, related_name="+", on_delete=models.CASCADE) The problem is, I now can't create a User without first creating an Avatar for that User. But I can't create an Avatar without a User. Having spent ages looking at it, I can't see how I can do this without allowing one of these relationships to be null, which seems wrong somehow. Is there another way to do it? -

django view creates new object instead of replacing it
I wrote a function like this which takes care of user payment information: def PaymentView(request): template = loader.get_template('reg/payment.html') payment = PaymentInfo.objects.get(user=request.user) if request.method == 'GET': if payment and payment.isPaid: return redirect('/dashboard') return HttpResponse(template.render(request=request)) if request.POST.get('proceed'): return redirect('/dashboard') else: payment = PaymentInfo(user=request.user) price = 252000 order_id = jdatetime.datetime.now().isoformat().replace(":", "").replace(".", "").replace("-", "") hyperlink = proceed_to_payment(payment, order_id, price) return redirect(hyperlink) and this is the object that it creates for users every time its called: class PaymentInfo(models.Model): id = models.AutoField(primary_key=True) user = ForeignKey(User, on_delete=models.CASCADE) isPaid = BooleanField(default=False) payment_number = CharField(max_length=32, null=True, default=None) order_id = CharField(max_length=32, null=True, default=None) track_id = CharField(max_length=50, null=True, default=None) card_no = CharField(max_length=16, null=True, default=None) hash_card_no = CharField(max_length=64, null=True, default=None) payment_date = DateField(auto_now_add=True, null=True) payment_verification_date = DateField(auto_now_add=True, null=True) it works just fine but imagine if a user clicks a certain button to get redirected to the payment page and cancel that payment and repeat this one more time. now the user has two seperate paymentInfo object. I want the first one to be updated with new info. what statement should I add to the views functiona? something like if payment.exists(), delete it or replace it some how!? -

Does transaction.atomic roll back increments to a pk sequence
I'm using Django 2.2 and my question is does transaction atomic roll back increments to a pk sequence? Below is the background bug I wrote up that led me to this issue I'm facing a really weird issue that I can't figure out and I'm hoping someone has faced a similar issue. An insert using the django ORM .create() function is returning django.db.utils.IntegrityError: duplicate key value violates unique constraint "my_table_pkey" DETAIL: Key (id)=(5795) already exists. Fine. But then I look at the table and no record with id=5795 exists! SELECT * from my_table where id=5795; shows (0 rows) A look at the sequence my_table_id_seq shows that it has nonetheless incremented to show last_value = 5795 as if the above record was inserted. Moreover the issue does not always occur. A successful insert with different data is inserted at id=5796. (I tried reset the pk sequence but that didn't do anything, since it doesnt seem to be the problem anyway) I'm quite stumped by this and it has caused us a lot of issues on one specific table. Finally I realize the call is wrapped in transaction.atomic and that a particular scenario may be causing a double insert with the same … -
