Django NUMBER_GROUPING is not applying THOUSAND_SEPARATOR
I'm using Django (1.11.7) with Python (2.7.1) and I have this set in my settings file. USE_I18N = False USE_L10N = False USE_TZ = False DECIMAL_SEPARATOR = ',' THOUSAND_SEPARATOR = '.' USE_THOUSAND_SEPARATOR = True NUMBER_GROUPING = 3 I would expect Django to group numbers in groups of 3 and add a THOUSANDS_SEPARATOR in between. When I print out variable in template I get 5172,00 where I'm expecting to get 5.172,00 How can I solve this and is this a bug in Django itself or a settings misconfiguration? -

Add items to manytomany field from views.py
I have a situation where i need a model that has a manytomany field that references other objects of the same class. This is because i have devices that have dependencies, which are each other. Is there a way to update an objects linked class manytomany field? models looks like this: class Device(models.Model): hostname = models.Charfield(max_length=50) class Dependency(models.Model: device = models.ForeignKey(Device, related_name='dependencies', on_delete=models.CASCADE) In the view it open a .yml file that has all the data of each device including which dependencies each device has. views.py def new_build(request): if request.method == 'POST': devices = Device.objects devices.all().delete() with open('device.yml', 'r') as data: device_data = yaml.load(data) for device in device_data: device.hostname = device_data[device]['hostname'] if device_data[device]['dependencies']: device.dependencies.add(device_data[device]['dependencies']) However, clearly this isn't working or i wouldn't be posting on here. Is there another way to achive this? can i have a manytomany field within the same 'Device' class referencing other objects of the same class? -

Docker + Django, docker-compose up does not seem to run migrate command
I am currently creating a Django app that is supposed to run a web scraping code as soon as it starts and then respond with certain data on requests via REST API. The requirement is that it must run on Docker which is causing me a following problem: when using docker-compose up the image is being built properly, db service runs but then I get an error saying that relations in my DB do not exist. I can rectify this by running docker-compose run [service] manage.py migrate but this is a manual solution and won't work when someone clones the app from git and tries to run it via docker-compose up. I have used command: python /teonite_webscraper/manage.py migrate --noinput in my docker-compose.yml but it does not seem to run for some reason. docker-compose.yml: version: '3.6' services: db: image: postgres:10.1-alpine volumes: - postgres_data:/var/lib/postgresql/data/ web: build: . command: python /teonite_webscraper/manage.py migrate --noinput command: python /teonite_webscraper/manage.py runserver 0.0.0.0:8080 volumes: - .:/teonite_webscraper ports: - 8080:8080 environment: - SECRET_KEY=changemeinprod depends_on: - db volumes: postgres_data: Dockerfile: # Use an official Python runtime as a parent image FROM python:3.7 # Set environment varibles ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 # Set the working directory WORKDIR /teonite_webscraper # … -

Python - Update HTML automatically when variable change
I want to use python to create a web-based user interface for an app. I've already worked with flask, but I would also change to Django or something similiar if necessary. The app I'm working on has got a background loop, that changes some global variables sometimes. I want my interface (webpage) to react to the variable changes, but just can't figure out how to do this. Again, I'm not limited to any specific framework. This should happen in real-time, so I don't want to periodically send AJAX-Requests to make this happen. Can someone help me out? Thanks in advance. -

POST request with nested JSON parameters malformed in request.POST
Inside integration tests, I try to make a POST request with a nested JSON parameter (this is just one of the approaches I tried): test_function(admin_client): admin_client.post(some_url, json.dumps(some_nested_json), content_type='application/json', headers={'Content-type': 'application/json; charset=utf-8'}) I've also tried all sorts of different combinations for the parameters etc., everything I could find on the web, but I can't get the proper JSON output in the received request.JSON. I get one of these three cases: request.POST contains the first level of JSON plus the arrays of second level JSON keys request.POST contains the first level of JSON plus an empty second level JSON request.POST is empty, but request.body contains the whole nested JSON, in expected format What am I missing here? I'm using Python 2.7. -

Missing default model permissions during unit testing in Django app
There are default model permissions for view/add/update/delete in database when applying migrations(it's working with my main DB): sadmonad=# select count(*) from auth_permission; count ------- 32 (1 row) But in django.test it is not so: it only creates permissions for django modules like auth, session, contenttype, etc: test_sadmonad=# select count(*) from auth_permission; count ------- 24 (1 row) I'm using Django 2.1.1(in my models I didn't specify custom permissions), so what should I do to fix this behaviour? -
Django Execute Function When DateTimeField Equals Current Date and Time
So I have implemented a subscription product to my website. When they start the subscription, the current date and time is stored into the database. When they cancel the subscription, a period of time is added onto the start date so I know when to cancel the subscription and change some values elsewhere. This is fine, I know how to use Django and Python, however, I am stuck on the last bit of, when the cancel date comes around in the future. Question: How do I execute a function when the cancel date (in the db) is equal to current date and time. Below is an simple example of the model I will be using: models.py class Subscriptions(models.Model): subscription_id = models.AutoField(primary_key=True) start_date = model.DateTimeField(auto_now_add=True) cancel_date = model.DateTimeField(auto_now_add=False) person_id = model.ForeignKey('Persons') class Persons(models.Model): person_id = models.AutoField(primary_key=True) value_to_change = models.BooleanField() Before you ask I have not attempted any code as I couldn't find a solution for this problem. Thanks <3 -
Removing built-in fields from wagtailstreamforms
I'm trying to remove the date, time, and multiselect fields from the wagtailstreamforms Admin page, such that they can't be used in any form site-wide. I've tried calling register('<field_name>', None) to get rid of it, but this doesn't work: # wagtailstreamforms_fields.py from wagtailstreamforms.fields import register @register('date', None) @register('time', None) @register('multiselect', None) And creating an AppConfig to manually purge the wagtailstreamforms.fields._fields dict of the entries, but that doesn't seem to work either. I've made sure that this AppConfig is part of an app that loads after wagtailstreamforms. class UpdatedConfig(AppConfig): name = 'my_new_app' def ready(self): from wagtailstreamforms.fields import _fields _fields.pop('date') _fields.pop('datetime') _fields.pop('multiselect') for x in _fields.keys(): print('{}: {}'.format(x, _fields[x])) Is there any way to do this, hacky or otherwise? I'm using Wagtailstreamforms 3.1 and Wagtail version 2.2.2. -
Change the uploaded image format in django
This is the model I am using to upload and rename image files in Django, @deconstructible class PathAndRename(object): def __init__(self, sub_path): self.path = sub_path def __call__(self, instance, filename): ext = filename.split('.')[-1] filename = '{}.{}'.format(uuid4().hex, ext) return os.path.join(self.path, filename) class Diagram(models.Model): diagram = models.FileField(upload_to=PathAndRename("diagrams/")) text = models.CharField(max_length = 48) date = models.DateTimeField(auto_now_add=True, blank=True, null=True) Now the images are saved in both .jpg and .png as per its original format. My question is how to make all the uploads, be it .jpg file or .png file to store in common format e.g. all images in .png file. -
Django REST framework not looking for URL encoded detail views
I have a model whose Primary Key is a TextField. This is a minimalistic reproduction of my issue: Model: class Filename(models.Model): path = models.TextField(primary_key=True) Serializer: class FilenameSerializer(ModelSerializer): class Meta: model = Filename fields = '__all__' View: class FilenameViewSet(ModelViewSet): queryset = Filename.objects.all() serializer_class = FilenameSerializer I'm using a DefaultRouter for URLs. Here is the problem: If I sent {"path":"test"} with a POST /filename/ I can perfectly retrieve my object with GET /filename/test/ as you would expect. However, if I POST /filename/ something like {"path":"c:\\test"} I would expect either GET /filename/c%3A%5Ctest/ or GET /filename/c%3A%5C%5Ctest/ to be the proper way to get it, but none of those works. Does anybody knows what's going on? -
Django, looking to change html for a variable class after Ajax function is successful. How can I pass a variable into the css class?
My button code is currently: <script type="text/javascript"> var forLoopCounter = '{{forloop.counter}}' function toggleLike(){ $.ajax({ url: "{% url 'photo_blog-post_like_api' post.id %}", success: function() { $("#likeCount").html(data.like_count + ' likes'); $('.imageElement').html(data.img); console.log(data); } }); }; </script> On the $('.imageElement') I actually want to pass in the forLoopCounter variable, so for the first loop it reads $('.imageElement1'), the second loop it reads $('.imageElement2'), etc. How do I pass this variable into the string? Thanks!
