What is a strategy of deploying Django + Vue with docker?
I don't fully understand how should I build and deploy the docker container with my app. I have an app which has two parts - REST API with Django REST Framework and SPA with Vue.js. API is connected to Postres. The question is, should I build a single container where I install SPA, API and database, or have app-container linked with a separate database container. I plan to build containers with gitlab ci and deploy to heroku. Or what is the best practice? -

Is there a simple way to handle SECRET_KEY update for encrypted fields?
Let's begin with two assumptions: Some of database fields like third party access tokens are encrypted using e.g. Fernet and SECRET_KEY as encryption key. SECRET_KEY needs to be changed, because of security problem. What would be the best thing to do in such situation? I assume that I should change the SECRET_KEY immediately after I've fixed the security hole, however if I do that I'll essentially lose access to all of the encrypted data. What I have came up with is to first do a migration, which would temporarily replace encrypted fields with simple charfields/textfields + data migration to unencrypt stored values. Then change the SECRET_KEY. Finally bring the encrypted fields back, again with a data migration to encrypt stored values. It seems like a great hassle though, is there a better/simpler/faster way to handle such situation? -
Django/rest: return user's data plus one more json in one response
I'm using django rest-framework in python 3.5. When User.objects.filter(uid = data['id']).exists() I want to combine user's data and {"isnew":"TRUE"} in one json string and return it as response. User's data have this structure: I have the following view function. class UserRegister(CreateAPIView): permission_classes = () serializer_class = RegisterUserSerializer def post(self, request): serializer = RegisterUserSerializer(data=request.data) # Check format and unique constraint if not serializer.is_valid(): return Response(serializer.errors, \ status=status.HTTP_400_BAD_REQUEST) data = serializer.data if User.objects.filter(uid = data['id']).exists(): user = User.objects.get(uid = data['id']) json_resp = { "user":JsonResponse(user), "isnew":"TRUE"} return Response(json_resp, status=status.HTTP_200_OK) else: u = User.objects.create(uid=data['id'], firstname=data['firstname'], yearofbirth=data['yearofbirth'], \ lastname=data['lastname'], othernames=data['othernames']) u.save() return Response(serializer.data, status=status.HTTP_201_CREATED) Then I get the error TypeError: <User: User object> is not JSON serializable.

How can I serialize a single Django object to geojson?
I'm trying to serialize a single Django object to geojson format. I was able to do this if multiple objects is given: test = Test.objects.all() test_json = serialize('geojson' , test, fields=('test_type', 'wkb_geometry')) test_geojson = json.loads(test_json) test_geojson.pop('crs', None) test_geojson = json.dumps(test_geojson) To make the serializer accept the single object I modify it to: test_json = serialize('geojson' , [test], fields=('test_type', 'wkb_geometry')) However, the error now would be Test is not iterable in my Django template leaflet map. How can I turn one object to geojson using serializers? Do I have to do it manually? -

Django Rest Framework Token for Vue js (with axios) requests
How can I pass the token in vue js requests, actually axios requests. For example, I need to specify: axios.defaults.headers.common['Authorization'] = "Token " + $how_can_i_get_the_token_here; I don't understand how can I get the token inside the template without some security risks (I'm just being paranoic here). The code that generates the token is: @receiver(post_save, sender=settings.AUTH_USER_MODEL) def create_auth_token(sender, instance=None, created=False, **kwargs): if created: Token.objects.create(user=instance) So, I need the token for the specific user that is logged in. For csrf, I have done this: # in template <script>window.csrf = "{{ csrf_token }}";</script> # in js file axios.defaults.headers.post['X-CSRFToken'] = window.csrf; Is this a good idea? What's the best approach? Thanks in advance for answers! -

many to many table in django without using manytomanyfield
rather than using the models.ManyToMany field in django i just set up a intermediary field with a bunch of foreign keys. is there any reason why this wouldn't work. I can't think of any but why not see if any of you have tried the same. class Authorization(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, ) permission = models.ForeignKey( 'venueadmin.Permissions', blank=True, null=True) #venue = models.ForeignKey(venue) <-- commented out cause I haven't made the model its referencing yet. -

Automatically update a field on one model after saving another [Django 1.11][Python3.x]
I am learning how to use the post_save signal on Django. Though I am not getting any errors, what I want to do will not work. I have a model (Model) that is supposed to aggregate and average the ratings from the Review model and saves that number in a field called "average_rating." I want the averaging to be done once a user provides a rating on the "Review" model and for the average rating to automatically be calculated and updated on the "Model" model. I know that I can do this with a post_save signal. But I am not sure how. How can I do what I am trying to do? Thanks in advance. models.py from django.db import models from django.db.models import Func, Avg from django.urls import reverse from django.template.defaultfilters import slugify from django.db.models.signals import post_save from django.dispatch import receiver class Model(models.Model): name = models.CharField(max_length=55, default='') slug = models.SlugField(unique=True) average_rating = models.DecimalField(decimal_places=1, max_digits=2, default=0.0, blank=True, null=True) def __str__(self): return self.name def save(self, *args, **kwargs): self.average_rating = self.review_set.aggregate( rounded_avg_rating=Round(Avg('rating')))['rounded_avg_rating'] self.slug = (slugify(self.name)) super(Model, self).save(*args, **kwargs) class Review(models.Model): RATING_CHOICES = [ (1, '1'), (2, '2'), (3, '3'), (4, '4'), (5, '5'), ] model = models.ForeignKey(Model, null=True) rating = models.IntegerField(choices=RATING_CHOICES, default=1) review_date … -
