django access already existing table as you would a table created via a model
I am using the django-background-tasks packages to run a couple of tasks. This package creates two tables in my database (BackgroundTask & BackgroundTaskCompletedtask). I would like to create a page that reads the BackgroundTaskCompletedtask so I can check the status of of the background tasks. However I do not know how to access this database. For example, with a table I have created via model: class Set(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) code = models.CharField(max_length=64) ... I can used Set.objects.order_by('-releaseDate', 'name') to access that table. However when I try to use BackgroundTaskCompletedtask.objects... I can seem to import it in my views.py file. how to I access a table created via a package that doesn't exists in my model.py file. -

How to mock googleapiclient in a Django test environment

Unable to find root cause of warning message indicated as [django.request:230]
The log file contains warnings about "Unauthorized" access to certain API URLs. The warning's indicator says "[django.request:230]", and I suppose it means the trigger is line 230 of a source code file related to django.request. However, I'm unfamiliar with Django and PyCharm IDE, so I couldn't find out exactly which file. I hope to find out the root cause of this warning message and address it.

How can I optimise requests/second under peak load for Django, UWSGI and Kubernetes
We have an application that experiences some pretty short, sharp spikes - generally about 15-20mins long with a peak of 150-250 requests/second, but roughly an average of 50-100 requests/second over that time. p50 response times around 70ms (whereas p90 is around 450ms) The application is generally just serving models from a database/memcached cluster, but also sometimes makes requests to 3rd party APIs etc (tracking/Stripe etc). This is a Django application running with uwsgi, running on Kubernetes. I'll spare you the full uwsgi/kube settings, but the TLDR: # uwsgi master = true listen = 128 # Limited by Kubernetes workers = 2 # Limited by CPU cores (2) threads = 1 # Of course much more detail here that I can load test...but will leave it there to keep the question simple # kube Pods: 5-7 (horizontal autoscaling) If we assume 150ms average response time, I'd roughly calculate a total capacity of 93requests/second - somewhat short of our peak. In our logs we often get uWSGI listen queue of socket ... full logs, which makes sense. My question is...what are our options here to handle this spike? Limitations: It seems the 128 listen queue is determined by the kernal, and the … -
Optimize code of a function for a search filter in django with variable numbers of keywords - too much code, i'm a beginner
Hello great community, i'm learning django/python development, i'm training myself with development of a web app for asset inventory. i've made a search filter, to give result of (for example) assets belonging to a specific user, or belonging to a specific department, or belonging to a specific brand, model or category (computers, desks, ecc..) now (after a lot) i've done with multiple keyword search (for example) if somebody type in the search box the department and the category and obtain the relative results (for example all desk in a specific department, or all computer of a specific model in a specific department). i've made it in a "if" check form that split the keyword in single words, count it and apply progressive filtering on the results of the previous keys in sequence. but i'm not satisfact of my code, i think it's too much "hardcoded" and instead of creating an IF condition for each number of keyword (from 1 to 3) i wish like to code something that is not so dependent in the number of keyword, but is free. Here's the code of the view, i hope someone can give me the right direction. def SearchResults(request): query = request.GET.get('q') … -
How to display pdf from an HttpResponse in Django after jquery post request?

Generate Random String for Model Field in Django
I am using DRF and have a couple models where I want to generate unique numbers separate from ID's. For example, one model would have a number like PRJ023400 and another would be TSK2949392. I created a utility function to generate random numbers and as the field and attempted to use this function as the default. number = models.CharField(max_length = 10, blank=True, editable=False, default='PRJ'+create_new_ref_number()) The problem I am facing is that this only generates a new string when running a migration. What would be the best approach to make this work? Cheers!
