Why does my dependent dropdown form act up?
I am attempting to implement a dependent dropdown form for my project. I want the makes dropdown to be dependent of the year of the vehicle. The models dropdown entries should be dependent on the year and make dropdown entries selected. Finally, the repairs dropdown should be dependent on the year, make, and model selected. However, this is not the case. In my django database, I have two entries titled "Chevrolet" that are connected to years 1980 and 1981 via ForeignKey. Both of these entries are connected to an entry titled "Camaro". Another entry I have stored in my backend database has 1981 as the year, "Ford" as the make (connected to 1981 via ForeignKey), and "LTD Crown Victoria" and "F-150" as models. While the year and makes appear as they should, the other entries do not. I can only get the appropriate models to appear in the dropdown box after I select 1981 as the year and "Ford" as the model. Afterwards, I am able to see the models connected with the 1981 entry for "Chevrolet". Code from my Home.html file {% load static %} <!doctype html> <html lang="en"> <link rel="stylesheet" href="{% static 'css/edits.css' %}"> <head> <meta charset="UTF-8"> <meta … -

Django - combining querysets from different models and serializing them
I am a newbie trying to build an e-commerce website for fun. Firstly, I take the query parameters from the url, then find the fitting products and then try to find the corresponding images. However I cannot find a way to: combine a queryset of products and a queryset of images (connected with each other by a foreign key) serialize them into a JSON, to show on the frontend I am using postgresql.

Django reverse accessor clash - multiple uses of a model
I have two models, Photo and Story. The Story model uses the Photo a couple different ways - for a thumbnail, a header photo, and a gallery. I am storing an optional Story reference in the Photo model. This was causing a E.304 error: (fields.E304) Reverse accessor for 'stories.Story.header_image' clashes with reverse accessor for 'stories.Story.thumbnail'. I added related_name='+' to both the thumbnail and header_image fields. This disallows the backward relation and got rid of my reverse accessor clash issue. I was able to set up a PhotoInline in the Django admin, but also realized that there is now no way for a user to add a thumbnail or header_image inline - the typical "edit" and "add" options aren't available. What do I need to change about my models or admin config to allow for that? I tried changing the related_name params to name the relationships instead of disallowing them, but that didn't seem to help - not sure if I would need to use those values somewhere. class Story(models.Model): title = models.CharField(max_length=200) author = models.CharField(max_length=200) thumbnail = models.ForeignKey('Photo', on_delete=models.CASCADE, null=True, blank=True, related_name='+') header_image = models.ForeignKey('Photo', on_delete=models.CASCADE, null=True, blank=True, related_name='+') content = tinymce_models.HTMLField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) created_by = … -

504 Gateway Timeout in Kubernetes Deployed Django Application with Nginx Ingress
I am facing a 504 Gateway Timeout issue with my Django application deployed on Kubernetes. The application is running behind an Nginx ingress controller. My longer running requests keep timing out after 1 minute exactly. I'm not sure what could be causing the issue as i've altered the timeouts. My Ingress resource has the following annotations: Annotations: ingress.kubernetes.io/proxy-body-size: 100m ingress.kubernetes.io/proxy-connect-timeout: 1000 ingress.kubernetes.io/proxy-read-timeout: 1000 ingress.kubernetes.io/proxy-send-timeout: 1000 ingress.kubernetes.io/send-timeout: 1000 ingress.kubernetes.io/uwsgi-read-timeout: 1000 Additionally, I have the following Nginx ConfigMap settings: allow-snippet-annotations: "true" client-max-body-size: 100m hsts-max-age: "1" max-fails: "100" proxy-buffering: "off" proxy-connect-timeout: 610s proxy-read-timeout: 600s proxy-send-timeout: 300s uwsgi_connect_timeout: 600s worker-shutdown-timeout: 86400s I run Django using gunicorn like this: /usr/local/bin/gunicorn config.wsgi -w 2 -b 0.0.0.0:5000 --chdir=/app --timeout 1000 --limit-request-line 0 The application works fine locally and doesn't have any performance issues. I have tried increasing the timeouts and resources for the application, but the issue persists. I would appreciate any suggestions on how to resolve the 504 Gateway Timeout error or any tips on how to further debug this issue. -

Draft.objects.filter(data__communications__*__name__in=['john', 'erin']).count() How can I write a Django/Postgres query to return DRAFT1 and DRAFT2 as the result? -

Point custom domain to a different website Django
I have a Django project deployed to a ubuntu server from digital ocean, using Apache as the web server and mod_wsgi, a custom domain name from Namecheap, and an SSL certificate. It has everything needed to be a solid website. But I also have a flask app deployed on an EC2 instance from AWS, besides changing the name servers on NameCheap to point to my EC2 instance, what else should I do for my domain to point to my Flask app instead of my Django app? Is it just as simple as removing the domain name from ALLOWED_HOST in Django settings.py? or is this more complex now that I have an SSL certificate? I hope it's not a meaningless question.
