Cannot route traffic with Minikube + ingress + Django
In my local development setup, I'm using Django as the webserver (a-la python manage.py runserver 8000) and I'm able to kubectl port-forward <django_pod> 8000 my traffic to my local dev machine so I can interact with my site by browsing to http://localhost:8000/whatever. I've configured my ALLOWED_HOSTS to include localhost to enable this. However, I'd like to avoid using port-forward and go the more proper route of running my traffic through the Kubernetes ingress controller and service. On the same Minikube cluster, I have ingress configured to point certain traffic urls to a very rudimentary nginx pod to confirm that my ingress+service+pod networking is working properly. All other urls should route to my Django app. In my ingress controller logs, I can see the traffic being sent to the service: 192.168.64.1 - [192.168.64.1] - - [22/Nov/2019:03:50:52 +0000] "GET /test HTTP/2.0" 502 565 "-" "browser" 24 0.002 [default-django-service-8000] [] 172.17.0.5:8000, 172.17.0.5:8000, 172.17.0.5:8000 0, 0, 0 0.000, 0.000, 0.000 502, 502, 502 aa2682896e4d7a2052617f7d12b1a02b When I look at the Django logs, I don't see any traffic hitting it. My ingress servicePort is 8000, the django-service port is 8000 (I've just let it default to ClusterIP), the pod's spec.containers.ports.containerPort is 8000, and the process has … -

Django auto-populating form field from API call
I am trying to auto-populate one field of a Django form based on the query response of an entry into another field. I would like to do so before the form is submitted, displaying the autopopulated value in the field and maintain the user's ability to edit. (Example, I type 'a handful of bananas' into the name field, when that field blurs it queries the api and fills the carbs field with the # of carbs a handful of bananas has) Right now I have the ajax function to query: $('#recipe-query').on('blur', function(event){ event.preventDefault(); console.log("blur") query_macros(); }); function query_macros(){ var dataStr = "APIKEYREDACTED" var ingredParam = encodeURI($('#recipe-query').val()) dataStr = dataStr + ingredParam if($('#recipe-query').val() && $('#should-query').val()){ $.ajax({ url: "https://api.edamam.com/api/nutrition-data", data: dataStr, type: "GET", dataType: "json", success : function(json){ console.log(json); console.log(json.totalNutrients.CHOCDF.quantity) $('#carbs-query').value = json.totalNutrients.CHOCDF.quantity; }, error : function(xhr, errmsg, err){ console.log(xhr.status + ": " + xhr.responseText); } }); } } this is the form class NutritionForm(forms.ModelForm): class Meta: model = Nutrition fields = ('food_name', 'autofill_macros', 'grams_of_fat', 'grams_of_protein', 'grams_of_carbs', 'date') widgets = { 'food_name': forms.TextInput(attrs={ 'id': 'recipe-query' }), 'autofill_macros': forms.CheckboxInput(attrs={ 'id': 'should-query' }), 'grams_of_fat': forms.TextInput(attrs={ 'id': 'fat-query' }), 'grams_of_protein': forms.TextInput(attrs={ 'id': 'protein-query' }), 'grams_of_carbs': forms.TextInput(attrs={ 'id': 'carbs-query' }) } and model class Nutrition(models.Model): food_name … -

Extend a model using OneToOneField
I'm trying to extend django-taggit Tag model to have an added_by (ForeignKey to User) field on it, so I can query all tags added by a particular user. So, I have created an app and in models.py there I have created another model, called MyTag and I have a OneToOneField to Tag on it: from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from django.dispatch import receiver from taggit.models import Tag class MyTag(models.Model): tag = models.OneToOneField(Tag, on_delete=models.CASCADE) added_by = models.ForeignKey(User, on_delete=models.CASCADE) @receiver(post_save, sender=Tag) def create_tag(sender, instance, created, **kwargs): if created: MyTag.objects.create(tag=instance, added_by=???) @receiver(post_save, sender=Tag) def save_tag(sender, instance, **kwargs): instance.mytag.save() The issue is, I can't access request.user from inside models.py. How do I overcome the issue, i.e. how do I properly extend django-taggit's Tag model to have added_by field on it? -
Hosting Django Rest framework on its own server
So I have an angular front end with an Django rest framework backend that's hosted on a single ubuntu 18.04 VPS box running apache. The front end is hosted on port 80 and the backend is at port 8000 and we noticed it seems like a lot of networks block port 8000. So what happens is if I logon on a public wifi you can see the front end but you can't access the backend. I need some guidance on how to make this work. Right now it's setup like so Api requests are: http://myapp.com:8000 In the future all API quests should be: http://myapp.com/api or maybe even a separate server that's http://api.myapp.com I'm asking for some guidance on this issue. Is there anyway to just make apache think that all requests are on port 80/443 and i don't need the 8000 anymore? and for a small app is that an okay practice? OR should I just run the backend on a separate server and if so how do I set that up? all guides seem to point to putting that on 8000. Any links and guidance on this issue would be appreciated. -

How to do backward relationships lookup for all model objects in Django?
I want to have a list view of all products from Product model with their own image URLs from ProductImage model. Each product may have multiple images. models.py: class Product(models.Model): product_id = models.CharField(max_length=6) material = models.ForeignKey(Material, on_delete=models.SET_NULL, null=True) name = models.CharField(max_length=50) created_at = models.DateTimeField(auto_now_add=True) enabled = models.BooleanField(verbose_name='Active') def __str__(self): return self.name clsas ProductImage(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) url = models.URLField(max_length=250) created_at = models.DateTimeField(auto_now_add=True) enabled = models.BooleanField(verbose_name='Active') def __str__(self): return self.url I've been trying to implement the queries from this Django documentation. But the example specifically target an object by its id. How to do the same thing with all objects? b = Blog.objects.get(id=1) b.entry_set.all() # Returns all Entry objects related to Blog. Is it possible to do it without changing the Foreign Key relation into productimage = models.ManyToManyField(ProductImage) in Product model ?

Multi-tenant redirect to sub-domain based on User Id
I am implementing Django-tenant-schemas on a SaaS website I am building and am wondering how to allow users to login at the main site and be redirected to the tenant specific subdomain their user account exists at. e.g. User goes to www.mysite.com and tries to log in - because, after all, this is the site they expect to log in at - but their user account is actually associated with www.tenant1.mysite.com. How do I go about redirecting the user automatically when they attempt to log in at the main domain? I assume there is something very simple that I am not seeing. Thanks in advance! Note: I want the user to log in to their sub-domain and only their sub-domain, not as a user across all domains (which is what SESSION_COOKIE_DOMAIN does I believe). -
Why does Django tell me that a field clashes with a field in the base class when that field only exists in the subclass?

Django Users, groups and organizations for multi vendor app, how to?
I'm building a marketplace that allows users to sign up with a company or organization, add or invite other users to that company and manage those users. All users can create listings (products or service). Currently I have an abstract user model and a company model with a foreign key to the user, which works well if a company only has one user, it looks like this: class User(AbstractUser): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) phone_number = models.CharField(max_length=15) email = models.EmailField(unique=True) objects = UserManager() def __str__(self): return self.first_name class Company(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) company_name = models.CharField(max_length=100, unique=True) company_address = models.CharField(max_length=100, unique=True) company_website = models.URLField() company_verified = models.BooleanField(default=False) def __str__(self): return self.company_name What would be the best way to accomplish this, without giving the users permissions to the admin site? I've looked at using django-organizations, but the documentation seems poor and they don't support postgresql. -
Populate added_by field from CreateView
I have extended django-taggit TagBase model to include an added_by field as a ForeignKey to User: class TagBase(models.Model): name = models.CharField(verbose_name=_("Name"), unique=True, max_length=100) slug = models.SlugField(verbose_name=_("Slug"), unique=True, max_length=100) added_by = models.ForeignKey(User, on_delete=models.CASCADE) Everything works great, however I'm having an issue with populating that field from my CreateView.

Django Stripe Fake Card Causes TemplateDoesNotExist Error
When a person types in a fake credit card into my Stripe payment form, I get an error page saying "TemplateDoesNotExist at /memberships/payment/ followed by membership/membership_payment.html". The following lines of code get executed: views.py: https://dpaste.de/8EUX#L77,78,79,80,81,82,83,84,85 html files: https://dpaste.de/2Y37 I need a way to not show that error page and redirect the user back to /memberships/ and display a card decline message instead. However, if a user types in a valid card, that redirect is correct. Otherwise maybe I need a way to validate the card is able to be charged to see if it is a real one before being able to submit the form. Traceback has been included in the dpaste link. I am using this github project as a baseline so all files are mostly the same (except for my dpaste code updates): https://github.com/danialbagheri/video-membership Any help would be greatly appreciated. -

defautl image in the field "ImageField" - Django
I try to put an image in an ImageField by default. But I can't solve the problem. My first attempt at solution was the following: from django.contrib.staticfiles import finders result = finders.find('img/image.png') models.ImageField(upload_to = user_model_custom_upload, default = result) My second attempt at solution was the following: from django.conf import settings import os DEFAULT_AVATAR_PATH = os.path.join(settings.MEDIA_ROOT, 'images/no-avatar.png') models.ImageField(upload_to = user_model_custom_upload, default = DEFAULT_AVATAR_PATH) neither solution worked But something curious happens with the second method, is that at the time that Django searches for the image, the image path for Django is as follows: Not Found: /media/home/lcteen/Documents/Programming/Frameworks/Django/ibme_project/media/images/no-avatar.png I don't know what is currently happening, it's like the structure of my directories is in the media folder or something ... but my media folder doesn't change at all.

HTML5 video elements loading time
I just want to figure out why my website is serving video files without coherence. First of all, I have created my website on ODROID-XU4 and OS is Ubuntu. Also, using Django and Apache2 as Framework Anyway, here is my problem. Videos won’t start instantly when I click the play button But, funny thing is some video files with big size do play instantly. For example, when I upload 3GB of video(mkv) and click play button, it plays instantly. However, another video file which is only 1.8GB uploaded won’t be played before fully loaded. Please, I am waiting for answer from someone who had similar experience -
How do I create a Django admin section for managing content on an individual page, such as homepage?
I would like to allow an admin to edit content sections on a homepage, about page, or contact page. A content section with a changeable background image, or a content section with changeable text. Is there a built-in Django package that addresses this? If not, would you recommend another third-party Django integration? I have searched using similar questions and have found that there are very few related answers. -
