Heroku CI Unable to initialize CI build environment,
I'm setting up Heroku CI for my app and I'm getting the following error: Could not create test run. Unable to initialize CI build environment, please try again. Problem is I have no idea why.

Django request.body has incomplete data
I am sending a large amount of data to server from Android App using volley. The request which I receive in Django, sometimes has incomplete data. While doing json.loads(data) it throws ValueError: Unterminated string starting at: line 1 column 278491 (char 278490). It doesn't happen every time. What can be the possible error in my Django or Android Code? Sample Code: request_data = request.body data = json.loads(request_data) I am using Python 2.7 -

Celery tasks when specifying custom vhost in rabbitmq is not running
I am using celery and rabbitmq as the broker to handle my async tasks in my django projects. When I was using the default broker url, everything was working fine, but in my production server, I needed to run two django projects both of which will need a async task manager. Now, to do this I created two vhosts in rabbitmq. Then, I changed my CELERY_BROKER_URL in settings.py to amqp://guest:guest@localhost:5672/vhost_name in both projects. Then, I ran it using supervisor worker with the command celery -A proj worker -l info. Weirdly, one of my project is working fine, but in the other one the task is being received but not being executed! So, for that project I changed it to the default CELERY_BROKER_URL and it started working, and also ran the tasks which weren't executed. To debug, I ran the same thing on my local machine and the same thing happened. The project configurations are mostly similar apart from the number of tasks. The first project (which worked) had 3 tasks while the other had 8 tasks. Is this a bug? If not can someone point me to the right direction? celery.py in project root import os import logging from celery … -

How to include a parent object when serializing a Django Model?
I have two simple models with a foreign key relation like this: class Foo(models.Model): code = models.CharField(max_length=255) class Bar(models.Model): foo = models.ForeignKey(Foo) description = models.CharField(max_length=255) The current rest_framework-based serializers look like this: class FooSerializer(serializers.ModelSerializer): class Meta: model = models.Foo fields = ('id', 'code') class BarSerializer(serializers.ModelSerializer): class Meta: model = models.Bar fields = ('id', 'foo', 'description') So a GET request for a Bar will return something like this: { "id": 1, "foo": 2, "description": "[…]" } How do I change BarSerializer to instead return the full Foo object, like this: { "id": 1, "foo": { "id": 2, "code": "[…]" }, "description": "[…]" } ? Keep in mind I still need to be able to create a Bar by providing only a description and Foo ID. -

Combining Grunt and Webpack in Django projects
I have a Django project that has both Vue.js for SPA but also uses allauth and built in templates. Library management in the templating system is currently done with Grunt + package.json, Vue.js uses WebPack. How do people usually approach these kinds of projects? Do they get rid of Grunt and template and try to rework everything using SPAs? Do they use one directory for Grunt/WebPack/JQuery? Am I committing some cardinal sin by leaving both in? One of the tricky things is that I currently have two package.json files and that does seem like a problem. -
Checking if relationship exists with query
I am trying to check whether or not a following relationship exists using a query. First, I get all of the followers the user has and then I check whether or not the user follows those followers. Here are my models: class Following(models.Model): target = models.ForeignKey('User', related_name='followers', on_delete=models.CASCADE, null=True) follower = models.ForeignKey('User', related_name='targets', on_delete=models.CASCADE, null=True) created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return '{} is followed by {}'.format(self.target, self.follower) class User(AbstractBaseUser): username = models.CharField(max_length=15, unique=True) email = models.EmailField(max_length=100, unique=True) I am using the Django Rest-Framework so I go to the specific URL to get the information I need. After going to the URL, the output is expected. I get all the followers the user has. def get_queryset(self): requested_user = get_requested_user(self) return User.objects.filter(targets__target=requested_user).order_by('-targets__created_at'). \ annotate(is_following=Count('followers__follower', filter=Q(followers__follower=requested_user), distinct=True)) def get_requested_user(self): filter_kwargs = {'username': self.kwargs['username']} return get_object_or_404(User.objects.all(), **filter_kwargs) However, the problem is in the is_following annotation. I'd like to see whether or not the user follows each specific follower. If they follow that follower, then is_following should be 1 if not, then it is a 0. I'm getting incorrect results in is_following is there a way I can check if the user follows each specific follower? -

Django Admin or Angular JS
Guys i have a very simple project where i need 2 main screens, let's see: 1- The main and first screen is where user select a BANK account, something like a "combobox" when user choose a BANK ACCOUNT and click in confirm. 2- The second screen is just a list that shows all Bank Account(Selected in step 1) movements. So, I'm just starting with Django and create a Admin Site is very very simple and useful. But my project is not like a CRUD, as you can see. I need only one CRUD (BANK ACCOUNT) but another screens is not crud. So, my questions are: 1) Is better customize Admin Django to my case or create this pages in another language more customizable like Angular JS ? Django give me some "ready-to-go" CRUD's but i have to customize index page, menu bar, colors and logo. 2) Is a good choice use Django Rest Framework to generate a Viewset and build my frontend using Angular JS to consume this backend ? -

urandom in django model / mySQL Database
I am trying to store a urandom value into the mySQL Database of my Django project. The value must be totally random for cryptography purposes. I am trying for hours and I am really frustrated. I googled some answers but the solutions wont work. If I try this as here suggested Store os.urandom variable to Sqlite database in Django def createkey(): random_bytes = urandom(16) return b64encode(random_bytes) key = models.BinaryField(max_length=16, default=createkey) ... i get this error message django.db.utils.OperationalError: (1067, "Invalid default value for 'key'") I also tried it with the binascii library os.urandom() decoding Issue like this def createkey(): return binascii.hexlify(urandom(16)).decode() With that above i get this error message: string argument without an encoding I am using Python 3.6, Django 1.11.5 and a MySQL Database. Is there any way to store the value of urandom into a Django Model? I would like to store it in a CharField but I am also glad if it works with other Fields.
