Async tasks in Flask using rabbitmq and Celery
I created a Django restful API. I send a post request to my Django API which then sends a message to rabbitmq. I have a microservice(Flask) that listens to that queue and processes the information sent by the message broker. I want Flask to be able to process the messages in the queue sent by django asynchronously. I'm trying to use Celery for this but I'm stuck because I see that the task is received but not processed. Below is my code(Sorry for the mess): cel.conf.update(app.config, broker_url='amqp://guest:guest@localhost:5672/', result_backend='rpc://') @cel.task() def process_task(data): print("Processing task with data:", data) time.sleep(5) print("Processing task with data:", data) return "TASK IS DONE" @app.route('/persons/') def hello_world(): def test_x(ch, method, properties, body): decode_data = body.decode('utf-8') print("Process start") process_task.apply_async(args=('a',)) print("Done!") ch.basic_ack(delivery_tag=method.delivery_tag) connection_parameters = pika.ConnectionParameters('localhost') connection = pika.BlockingConnection(connection_parameters) channel = connection.channel() channel.queue_declare(queue='test_micro', durable=True) channel.basic_qos(prefetch_count=1) channel.basic_consume(queue='test_micro', on_message_callback=test_x) print('Started test creating Consuming') channel.start_consuming()``` -
AttributeError: 'HttpResponse' object has no attribute 'data'

Python multiple model files
This post is probably a bit more meta and less technical but.... I come from a background in C# and other C style languages. Been doing it a long time so old habits are hard to break. One of the hardest things about Python for me has been the lack of scope indicators for example. In C# there are curly braces and parenthesis and of course line break tokens all over the place. I get why python doesn't have them. But a thought occurred to me as I'm working on a django web app and the number of models I have is starting to pile up. So when I ask this question, it might just be a 'we've always done it this way' sort of thing on my part. In C# every class is generally expected to be in it's own .cs file. This does resort in large applications have hundreds of those files. Personally I find it easier to late stuff in multiple files inside visual studio, for example, than I do trying to find a single class inside one huge omnibus models.py file in pycharm. Obviously I know I can have my files any way I want. if … -
Exception Error on Password Reset loop for Django Project
I have created a login system with the ability to reset the password. The request is working perfectly when I click on "Forgot Password?"I receive the reset link however when I click the link in the email I get the error message. "Exception Type: TypeError at /accounts/reset_password_validate/MzM/brm129-52c795f84dc89b21234642b2166f5c4f/ Exception Value: reset_password() got an unexpected keyword argument 'uidb64'" I kept thinking the URL path was not routing but I have changed this twice and I am getting the same error message.

Different migration behavior when running with `--database`
We have a specific migration that fails when run with --database rather than running on the default connection. The migration attempts to insert a row omitting one of the fields. The model that has non-null fields and a default defined in the model. When run against the default database, this migration succeeds, but when run with --database it fails as it tries to insert null. This is not specific to the database being targeted. If I take the definition of this second database and plug it into default and run the migration, it succeeds. It only fails when it runs with a non-default database connection. This is happening on 2.2.28, but I tried upgrading up to 3.2.20 and the same behavior persists (not able to try with 4.x due to postgres version conflicts). -
FOREIGN KEY constraint failed when I'm creating a new category
I'm getting a FOREIGN KEY constraint failed error when I'm trying to create a new category in the admin panel, and this is the models.py file: `import datetime from django.db import models from UserAuthentication.models import User from shortuuid.django_fields import ShortUUIDField from django.utils.html import mark_safe STATUS=( ("Vente", "Vente"), ("Location", "Location"), ) Specification=( ("W/C douche", "W/C douche Interne"), ("W/C douche", "W/C douche Externe"), ("Eau", "Eau"), ("Cloture", "Cloture"), ("wifi", "Wifi"), ) Bookings_status = ( ("Accepter", "Accepter"), ("Refuser", "Refuser"), ("Traitement", "Traitement"), ) def user_directory_path(instance, filename): return 'user_{0}/{1}'.format(instance.user.id, filename) # Create your models here. class CategorieBienImmobilier(models.Model): cid1 = ShortUUIDField(unique=True, length=10, max_length=30, prefix="cbi", alphabet='abcdefg12345') title = models.CharField(max_length=200) picture = models.ImageField(upload_to='user_directory_path') class Meta: verbose_name_plural = "Categorie de bien Immobilier" def category_image(self): return mark_safe('<img src="%s" width="50" height="50" />' % (self.picture.url)) def __str__(self): return self.title class Ville(models.Model): Vid1 = ShortUUIDField(unique=True, length=10, max_length=30, prefix="vil", alphabet='abcdefg12345') title = models.CharField(max_length=200) picture = models.ImageField(upload_to='user_directory_path') class Meta: verbose_name_plural = "Ville" def ville_image(self): return mark_safe('<img src="%s" width="50" height="50" />' % (self.picture.url)) def __str__(self): return self.title class BienImmobilier(models.Model): Bid = ShortUUIDField(unique=True, length=10, max_length=30, prefix="bil", alphabet='abcdefg12345') title = models.CharField(max_length=200) proprietaire = models.ForeignKey(User, on_delete=models.SET_NULL, null=True) description = models.TextField(null=True, blank=True) categoriebienimmobilier = models.ForeignKey(CategorieBienImmobilier, on_delete=models.SET_NULL, null=True) ville = models.ForeignKey(Ville, on_delete=models.SET_NULL, null=True) status = models.CharField(choices=STATUS, max_length=30) picture = models.ImageField(upload_to='user_directory_path', default="Bid.jpg") Prix … -
How to add a custom display in Django admin UI for user with only "view" permission?
If I want to change how an object is added or changed in the Django admin UI, I can simply override the form (docs). For a user with only "view" permission (no add, no change, no delete), that form doesn't even show up. If I want to change how an object is displayed in the admin UI for a user with only "view" permission on the "detail page", what do I do? P.S. When I say "detail page" I mean the page rendered when you click on the object in the list view. The URL ends in "change", but nothing can be changed for a user without change permission. EDIT: Maybe change_form_template? EDIT 2: A related way to ask this might be: how are read-only fields shown on the change form, and how do I customize a read-only field display? I think if you don't have "change" permission, it's rendering the fields as read-only. EDIT 3: This answer says you can't customize read-only fields. So maybe this is not possible? -

How to redirect django to Google directly with Allauth
I don't have a code problem but a little aesthetic, I'm trying to make a simple login to an app with Django and be able to enter with Google and when I put the label to enter I would like it to direct the user directly to Google as it usually is, but the label sends them to an intermediate Allaut interface and then press another button and go, I would like to skip that interface but I've tried and it always directs me there Urls of proyect: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include("allauth.urls")), path('', include("pagina.urls")) ] Urls of app: from django.urls import path from . import views urlpatterns = [ path("", views.home), path("logout", views.logout_view) ] And the button's code: {% load socialaccount %} <h1>Google Login</h1> <a href="{% provider_login_url 'google' %}?next=/">Login with Google</a> -
Very slow queries in Django view for model with a lot of nested relationships
We have a dynamic endpoint that has a huge amount of nested aggregation before fetching all of the records. We've tried indexing the keys, but it didn't seem to make a difference on the speed. We looked at a few different methods of caching things, but because of the scale of the data, it's changing very frequently at a low level. Are there any other options or suggestions that we can try to do to optimize the aggregation of the records? For reference, we have a Job model with a bunch of data about that job. There are a few 1-to-many relationships between Job and some other models such as JobTask. There is also some data we need that has a 1-to-many relationship with JobTask. This means that there is a lot of essentially nested data we need for each job. As the database has grown, this query is getting noticeably slower for the users and we are trying to see if there is anything we can do to optimize it. We tried using the Prefetch() class in all of these prefetch_related() calls but that wasn't any help. Below are the views for the job and job list, which is … -
Considerations when replacing a Mixin with abstract Model subclass?
I have multiple Models that all need some shared functionality. My existing code uses a Mixin class: class MyMixing: some_class_variable = None @classmethod def get_headers(cls): return [field.name for field in cls._meta.fields] # ... and my models look like: class Something(models.Model): name = models.CharField(max_length=50) The above code shows an example, where my IDE shows error, because MyMixin doesn't have _meta. And there are multiple such issues, especially as I'm trying to add some more common functionality So I'm thinking it might be better to replace MyMixin with MyModel: class MyModel(models.Model): class Meta: abstract = True some_class_variable = None @classmethod def get_headers(cls): return [field.name for field in cls._meta.fields] then my models will look like: class Something(MyModel): name = models.CharField(max_length=50) Could this mess up my existing data? Other than database (and, of course, silly typos), is there anything else that might go wrong with that change?
