Celery second unregistered task
I have a doubt regarding the implementation of celery with rabbitMQ since only the first function (debug_task()) that I have defined in celery.py is executed. The problem is that send_user_mail(randomNumber, email) is not working. debug_task is working, so it's registered. This is the celery console [2022-10-08 22:28:48,081: ERROR/MainProcess] Received unregistered task of type 'callservices.celery.send_proveedor_mail_new_orden'. The message has been ignored and discarded. Did you remember to import the module containing this task? Or maybe you are using relative imports? Why it's unregistered? celery.py from __future__ import absolute_import, unicode_literals import os from celery import Celery from django.conf import settings from django.core.mail import EmailMultiAlternatives, send_mail os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'callservices.settings') app = Celery('tasks',broker='pyamqp://guest@localhost//') app.config_from_object('django.conf:settings') app.autodiscover_tasks(settings.INSTALLED_APPS) @app.task() def debug_task(): print("hi all") @app.task() def send_user_mail(randomNumber, email): subject = 'email validation - ServicesYA' cuerpo="Your number is: "+str(randomNumber) send_mail(subject, cuerpo ,'xxx.ssmtp@xxx.com', [email],fail_silently = False) return 1 This is init.py # This will make sure the app is always imported when # Django starts so that shared_task will use this app. from celery import app as celery_app __all__ = ('celery_app',) and in settings.py I add this line: BROKER_URL = "amqp://guest:guest@localhost:5672//" -
How to view multiple images under separate posts in profile page
I am building a social media website. On the profile page and home page are different posts. Each can have multiple images. I created a different model for images and set ForeignKey to Post model. The form for uploading text and images works fine because the images attach to each post in the database. However, I am having issues writing the views code for the page they are to display. I am getting just text with no images. I am trying to add an Id to each post in the views but I have no idea how to do that since they are all in one page and therefore have no separate urls. I don't know if that is the right approach. Help me please. Thanks. -
Suddenly ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable?
Suddenly my Django project showed me the following ImportError: "ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?". It ran fine before. I work on Mac m1 using PyCharm Professional. My Django is installed. My venv is activated. So, I guess I have problem with PYTHONPATH . My interpreter is exactly I would like to use: Actually I have some versions of Python. which Python shows me: (venv) user_name@computer_name project_name % which python python: aliased to /usr/bin/python3 (venv) user_name@computer_name project_name % which python3 /Users/user_name/PyCharmProjects/TrainingProjects/project_name/venv/bin/python3 (venv) user_name@computer_name project_name % which python3.9 /opt/homebrew/bin/python3.9 python3 -c "import sys; print(sys.path)" shows me: /opt/homebrew/Cellar/python@3.10/3.10.7/Frameworks/Python.framework/Versions/3.10/lib/python310.zip /opt/homebrew/Cellar/python@3.10/3.10.7/Frameworks/Python.framework/Versions/3.10/lib/python3.10 /opt/homebrew/Cellar/python@3.10/3.10.7/Frameworks/Python.framework/Versions/3.10/lib/python3.10/lib-dynload /Users/user_name/PyCharmProjects/TrainingProjects/project_name/venv/lib/python3.10/site-packages If I understand this output correctly, it means that there is no python 3.9 in my PYTHONPATH for now. In my settings.py, there are: import os import sys #not active from pathlib import Path BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) which $PYTHONPATH brings me PYTHONPATH not found. echo $PYTHONPATH brings me nothing. The export: export PYTHONPATH=$PYTHONPATH:/Library/Frameworks/Python.framework/Versions/3.9/bin/python3 didn't help. Any help is highly appreciated. -
Django One-To-Two Relation
I want to implement a case where model A has exactly two B instances and model B has exactly one A instance. What is the best way to implement this? class A(Model): b1 = OneToOneField(B) b2 = OneToOneField(B) If I use this I have to provide two different related names to b1 and b2 fields. I want be able to simply say b.a_set.first() and get the object since I know B will have single A. And this is not really oneToTwo I think, b1 and b2 could point to the same B object although this is not critical at the moment. class B(Model): a = ForeignKey(A) If I use this then it is OneToMany, I want to be explicit about relation, and be able to use a.b1 and a.b2. Also I will be accessing model B from model A frequently so this is very inefficient. It doesn't make sense to search through table B when I know there are exactly two related B instances. I should be able to store the corresponding B ids in table A like in the previous case. What would be a good way to implement this? -
Django Autocomplete Light not working with Bootstrap 5 Modal
I am newbie to Python and Django. This is my first post. Sorry if I omit relevant information. I'm using DAL on a form inside a Bootstrap modal. Clicking the dropdown list appears behind the modal. The autocomplete function works correctly if I do it outside of the modal. I'm using: Django: 4.0.5 django-autocomplete-light: 3.9.4 Bootstrap 5.2.2 Python 3.10.4 To try to fix it, I have created a style.css file with the following code, as indicated in: bootstrap modal with select2 z-index .select2-container { z-index: 9999 !important; } Now the list appears in front of the modal, but it doesn't allow typing in the search box. I've tried doing the following, but it doesn't work: https://select2.org/troubleshooting/common-problems $(document).ready(function() { $("#codigo_emplazamiento").select2({ dropdownParent: $("#FormularioCrear") }); }); I've tried removing tabindex="-1" from the modal, but it doesn't work. It seems to be related to this, but I can't get it to work: https://lightrun.com/answers/yourlabs-django-autocomplete-light-search-input-not-receiving-focus I really appreciate your help.

Why Is Ajax Creating a New Comment When I'm Trying To Edit An Existing One?
I am trying to do a Django Blog in Class Based Views. They're proving very difficult to me anyway. I feel like I'm pretty close...I suspect it's creating a new one because I'm combining DetailView and trying to include an UpdateView in my page. I'm overriding POST on the DetailView...and perhaps that's why when I try to do my Update of the comment the overriden Post on DetailView is overriding that action? Here's my code.... HTML... <!DOCTYPE html> <form method='POST' class="comment-form"> {% csrf_token %} <div class="spacer284"> {{ form.comment }} </div> <button class="button7" type="submit">Submit</button> </form> <div class="spacer285"> {% include 'suggestion_comments.html' %} </div> </div> {% endblock %} Note that I'm doing an include so that I can loop through the comments more easily... Here's the include template... {% if suggestion_comments %} <h2>Comments</h2> {% for comment in object.suggestion_comments.all %} <div class="spacer291"> <p><a href="{% url 'Main:associate_directory_associate_detail' pk=comment.author.id %}">{{ comment.author }}</a> {{ comment.created_on }}</p> <p class="spacer290">{{ comment.comment }}</p> <div class="spacer289"> <div class="upvote-comment-count">{{ comment.total_comment_upvotes }}</div> <div class="hide-delete"> <button type="button" class="button6" data-href="{% url 'Suggestions:suggestion_comment_like' comment.id %}">Like</button> </div> <div class="hide-delete"> <button type="button" class="button2" data-href="">Reply</button> </div> {% if comment.author == request.user %} <button type="button" class="button4" id="{{ comment.id }}" pk="{{ object.pk }}" href="{% url 'Suggestions:suggestion_comment_edit' object.pk comment.id %}">Edit</button> <div class="spacer159" … -
Accessing TemporaryFilePath in form_valid Django
Currently my users are able to upload files, as I am deployed via Heroku I am using Django-storages to upload to AWS S3 buckets. I am using a CreateView/UpdateView as below, this works well however I now want to be able to run an operation on the file before uploading to AWS, my research insofar suggests that I can use temporary_file_path() to do this in the form_valid however I am getting an error, UpdateView/CreateView class project_update(LoginRequiredMixin, UpdateView): model = Project form_class = ProjectForm template_name = "home/update_project.html" context_object_name = 'project' success_url = reverse_lazy("project-list") def form_valid(self, form): handle_uploaded_boq(form['boq_file'].temporary_file_path(), form.cleaned_data['project_title']) return super(project_update, self).form_valid(form) However I am getting the following error: 'BoundField' object has no attribute 'temporary_file_path' So what is the best way to run the operation handle_uploaded_boq() before the file is uploaded to AWS? -

Django/Gunicorn Request Takes Long Time To Begin Processing View
Looking into optimizing my application's request times and have done a lot of work to implement caching, reduce duplicate db calls, etc. However looking at our monitoring tools I see sometimes it looks like the request takes an exceptionally long time to even begin processing the view. Wondering if there is a way to explain this? Its making it hard to set a consistent SLO for API requests. My understanding of gunicorn workers and threads is admittedly limited but I don't believe we would be hitting any limits on our current setup. That is really the only place I can imagine the bottleneck on proccessing the request would be ex: no more threads or workers available to process. Django = 3.2.15 Django Rest Framework = 3.13.1 gunicorn = 20.0.4 Start Command "gunicorn", "--workers=4", "--threads=8", "--bind=0.0.0.0:8000", "--worker-class=uvicorn.workers.UvicornWorker", "webapp.asgi:application" This is running on ECS load balanced between 2 c6g.xlarge instances (4 vCPUs). -

Django Constructing Form With Multiple Dictionaries
I'm using FormWizard, which returns a list of forms once they have all been completed. I have split 1 model into multiple forms. I clean the data in the list of forms and store it in another list. Using: profile_data = [] profile_data += [form.cleaned_data for form in form_list] Which gives me data like: profile_data = [{'activity_level': 0}, {'date_of_birth': datetime.date(2022, 10, 1), 'gender': 'M', 'height_feet': 6, 'height_inches': 1}] I then want to use this data to construct the main Profile form: new_profile_form = ProfileForm(profile_data[0], profile_data[1]) This does not work, as it causes the form validation to fail. I am able to get it working by manually getting each item like: new_profile_form = ProfileForm({ 'activity_level': profile_data[0]['activity_level'], 'height_feet': profile_data[1]['height_feet'], 'height_inches': profile_data[1]['height_inches'], 'gender': profile_data[1]['gender'], 'date_of_birth': profile_data[1]['date_of_birth']}) Why am I unable to do it the first way mentioned? -
Serialise python object with other objects as properties
I have a custom written object to represent a computational graph. It has a two lists containg vertices and edges. I need to serialise this graph object in order to store it into a SQLite database. What's the best way to serialise this object? Do I need to make functions to return a dictionary in each child? The issue is that each vertex contains edges attached to itself. And each edge object contains their start and end vertex/node. Do I need to rethink my Graph class. My issue right know is I cant recursively serialise each object and it's child as would never meet a finished state/condition! Any help would be appreciated, or if you need more info let me know!
