App Services Docker container: didn't respond to HTTP pings on port: 80, failing site start
I'm having problems with deploying my Django Application to Azure App-services. I'm getting the error when checking the logs: didn't respond to HTTP pings on port: 8000, failing site start. See container logs for debugging. I've followed the instructions as stated here to resolve the problem, but still no luck: https://docs.microsoft.com/en-gb/archive/blogs/waws/things-you-should-know-web-apps-and-linux#NoPing This is my set-up I have this in my Dockerfile: EXPOSE 80 EXPOSE 8000 This is my dockercompose.yml version: '3' services: web: build: . command: bash -c "python projectile/manage.py makemigrations && python projectile/manage.py migrate && python projectile/manage.py runserver 0.0.0.0:8000" container_name: image_service volumes: - .:/image_service ports: - "80" - "8000" I have these settings in the App Service Config in the portal WEBSITES_PORT 8000 What's wrong here? Would be awesome if someone could help. me out. -
Does Cast Function perform rounding before casting Django?
I expect the Cast function of Django, to do only casting e.g 7.6 will be 7 without performing any rounding. For example in Mysql the following: select CAST(((<value> - 1) div 30) AS SIGNED INTEGER) With a value equal to 227 will produce 7. But with Django's Cast, the following: MyModel.objects.annotate(time_window = Cast((F('field') - 1) / 30, IntegerField())) will produce 8 for some record having the value 227 for field. Are my expectations are wrong, or there is some flag to prevent this rounding behavior? -

Django filter many to many relation, by its primary key in admin
How would you create a filter in django admin, that filters by the primary key of many to many relation? Example: I have 3 models: class Country(models.Model): name = models.CharField(max_length=30) class City(models.Model): country = models.ForeignKey(Country, on_delete=models.CASCADE) name = models.CharField(max_length=30) class Person(models.Model): favourite_cities = models.ManyToManyField(City) Now in the admin dashboard under Person, I want to filter favourite cities, by countries. I don't want to show all the cities, just cities that are for example in Germany, or France. Is this possible? Thank you for your answers -

How can I resolve a django.db.models.query.QuerySet error? I'm trying to use .groupby() to group my elements in my api response
I'm using django and I'm having trouble using the .groupby() method from the pandas library. The error message I'm getting in Postman is 'Value Error: Invalid file path or buffer object type: <class 'django.db.models.query.QuerySet'>'. I've tried searching for a sensible answer on Stack, the django docs and elsewhere but I don't understand what I'm looking for and what a potential solution could look like. Currently, returning serialize_user_logs give the API response below, however, returning the grouping_by_programme produces the QuerySet error. Desired outcome for the API response to group exercise data by type of programme as follows: User = { id: 1, username: 'asd', email: 'asd£gmail.com', programmes: { chest: [ { exercise_name: 'benchpress', weight: [0], lastweight_update: [] }, { exercise_name: 'fly', weight: [0], lastweight_update: [] } ], back: [ { exercise_name: 'rows', weight: [0], lastweight_update: [] }, { exercise_name: 'lat-pulldown', weight: [0], lastweight_update: [] } ], shoulders: [ { exercise_name: 'Overhead Press', weight: [0], lastweight_update: [] }, { exercise_name: 'lateral-raise', weight: [0], lastweight_update: [] } ], arms: [ { exercise_name: 'bicep-curl', weight: [0], lastweight_update: [] }, { exercise_name: 'dips', weight: [0], lastweight_update: [] } ], legs: [ { exercise_name: 'squats', weight: [0], lastweight_update: [] }, { exercise_name: 'leg-press', weight: [0], lastweight_update: … -

How can I send back an array from Django to React after fetching POST request?
So my web app is a combination of Django, React and BigQuery. What I want to do is to make a POST request from React to Django, and Django will fetch the table data from BQ before sending the table data back as an array to the React frontend. How can I achieve this? What I have so far: app.js const handleConfirm = () => { fetch("http://localhost:8000/get-data-instance/", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify(tableName), }); }; views.py def get_data_instance(request): client = bigquery.Client() if request.method == 'POST': table_requested = json.loads(request.body) query_string = f""" SELECT * FROM `project-id.dataset-id.{table_requested}` """ result = ( client.query(query_string) .result() ) records = [dict(row) for row in result] data_instance = json.dumps(str(records)) return render(request, 'frontend/index.html') I basically want to send back the data_instance created above. If I try to print data_instance, i get the correct output >> "[{'key': 1, 'Date': '2021-11-10', 'Hour': 1, 'Measurement': 2.0}]" So, now I'm just stuck on how can I pass this data back to React? Note: I'm not using DRF for this project. -
javascript exception Django [closed]
