`INSTALLED_APPS` from django's setting.py is not able to find my own pip package even though it is installed
I have created a pip package for my DRF application. I have tested the APIs of this package and it is working fine. Now I have decided to put it on PyPi so that my friends can also use it. This is how I uploaded my package to PyPi. (please note I already have an account on PyPi) Created source distribution - python setup.py sdist Check Manifest - check-manifest --create. Here I have made sure that all the module of my app are in the source distribution tar. The I created build distribution - python setup.py bdist_wheel sdit. wheel was already installed in my env. Then I installed twine and uploaded it to PyPi using command - twine upload --skip-existing dist/* Now to test this uploaded PyPi package I started a new Django Restframework project and installed it using pip install <package>. However when I mentioned it in the list of INSTALLED_APPS it return this error - ModuleNotFoundError: No module named. I have also check the virtual environment for the package at lib/python3.9/site-packages/ and yes I found the folder for my package. Where could I have possible went wrong. This is very weird problem. -

ValueError while migrating a model in DJango
I am trying to create a simple model in Django. The expected fields are some text and owner's user id. However, this is what happens when I execute manage.py migrate (makemigrations worked without an error). I would appreciate any clues to this!

Django form rendering api, custom renderer example
For pretty much all my Django forms, I loop through the fields and build the form HTML up manually. While reading the documentation I came across: https://docs.djangoproject.com/en/3.2/ref/forms/renderers/ I am not quite sure what the form renderer api is for. I have noticed I often style forms according to 2 different ways. Using the same Form, could I pass it into two different renderers to get the two different styles? Is my understanding correct? Can someone provide a minimum code example of how to implement the renderer API (which must at least implement render(template_name, context, request=None)). I don't quite understand how one implements the part to find the template from the template name. -
Django error: too many values to unpack (expected 2) after adding model record
The idea To make the code a bit more understandable, I will first explain what my code (from which the problem probably comes) is supposed to do in the first place: I save reports in my model. I give these reports their own ID or numbering, because this is absolutely necessary.This ID shall be structured as follows: <year><ascending number with leading zeros> Example: 2021001, 2021002, ..., 2022001 The code I have developed the following code for this purpose. Since the value is to be calculated automatically, I use the @property decorator. To be able to use the ID later more easily as a field and simply for my REST Api, I use the computed_property package. Extract from models.py: einsatznummer = ComputedTextField(blank=True, compute_from="einsatznummer_calc") @property def einsatznummer_calc(self): year_einsatz = self.einsatz_start.strftime('%Y') last_number = EinsatzPublic.objects.filter(einsatznummer__isnull=False, einsatz_start__year=year_einsatz).values_list('einsatznummer', flat=True) if EinsatzPublic.objects.filter('einsatznummer').count() >= 1: # if last_number == None : # last_number = 0 if last_number[:-1] != year_einsatz: last_number = 0 einsatznummer_gen = year_einsatz + (last_number + 1) return einsatznummer_gen else: einsatznummer_gen = (year_einsatz + 1) return einsatznummer_gen When I tried to add a record to the model (DeploymentPublic) I got the following error which I can't solve.

Intercepting a Django 500 error for logging, without creating/serving a custom 500.html
In order to log "some dependency, somewhere deep" errors that trigger a server error 500, without stack traces in the console log on production instances due to DEBUG=False, I implemented the standard custom 500 handler that a fair number of Stackoverflow questions about printing a stack trace for a 500 error recommend: import sys import traceback def server_error_500_handler(request): type, value, tb = sys.exc_info() print('\n----intercepted 500 error stack trace----') print(value) print(type) print(traceback.format_exception(type, value, tb)) print('----\n') However, these then also all say to end with render(request, '500.html'), whereas I don't want to serve a custom 500 page, but want the code to go "back" (if there is such a thing) to just serving whatever Django itself does already. Is there some way to make it do that? Or, is there some way to listen for the 500 event without hijacking the 500 error return codepath? -
After a post request redirect to the previous inputted selection
I have a single-select dropdown menu that allows a user to choose what table they want to display. For example, Student Info College Info Career Info I get the user's input with the following post request and by default 'student_info' is displayed: > table_input_selection = request.POST.get('table_selection', 'student_info') Using django's formset, each table is dynamically populated by a df depending on which table is selected by the user. Each table allows the user to make updates to the existing table on the gui. Issue: A user can select the 'college_info' (non-default) table and make updates to the table. However, when 'Update' is clicked a redirect will default to the 'student_info' (default) table. How can I make it so that on a redirect it will not redirect to the default 'student_info', but the previous selected 'college_info' table? -

Django queryset to return all values matching a specific field name
I'm using Django and Django REST, and I'm looking for the syntax to be able to run a queryset again some JSON data stored in one of my fields in my database to pull out certain bits of data into a list.

I will also have potential other rows in my database where the field_b__field_b_6 data may only have one "id" key.

How to automatically generate django rest framework documentation with parameters?

""" permission_classes = [permissions.IsAuthenticated] def list(self, request): id_machine = self.request.query_params.get('id_machine') name = self.request.query_params.get('name') queryset = TechnicalData.objects.all() if id_machine: queryset = queryset.filter(machine__id=id_machine) if name: queryset = queryset.filter(name=name) serializer = TechnicalDataSerializer(queryset, many=True) return Response(serializer.data) def retrieve(self, request, pk=None): queryset = TechnicalData.objects.all() technical_data = get_object_or_404(queryset, pk=pk) serializer = TechnicalDataSerializer(technical_data) return Response(serializer.data) I don't see any mention of the parameters in the documentation. How can I add them? I don't know if this helps but here is how I implemented redoc: schema_view = get_schema_view( openapi.Info( title="test API", default_version='v1', description=f""" # Public API **Reserved to authenticated users** Token Lifetime : * ACCESS_TOKEN_LIFETIME : {duration(settings.SIMPLE_JWT.get('ACCESS_TOKEN_LIFETIME'))} * REFRESH_TOKEN_LIFETIME : {duration(settings.SIMPLE_JWT.get('REFRESH_TOKEN_LIFETIME'))} ### Links [Get access token](************) ### Format Use `?format=` option in url: * `?format=api` (default) * `?format=json` """, … -
Django simple-history how to track ForeignKey relations?
I am using django-simple-history to track changes to some fields on my models. My simplified model setup: class Collection(models.Model): description = models.TextField() # ... history = simple_history.HistoricalRecords() class Item(models.Model): content = models.TextField() collection = models.ForeignKey(Collection, related_name="items", on_delete=models.CASCADE) # ... history = simple_history.HistoricalRecords() Now ideally I would like to see Item changes reflected in Collection.history. For example, if a new Item is added to a collection, I would like to have a new entry in Collection.history. Is this somehow possible? -

Python Get year to date from now
I have a drop-down in django/python3 to return metrics based on 30, 60, or 90-day activity. Want to add a year-to-date option as well but having trouble with the implementation. Here is the code so far. def get_period_from_request(request) -> Tuple[datetime, datetime]: period = request.GET.get("period") right_now = timezone.now() # trying to get ytd from now() to 1/1/???? # ytd = datetime.now().date().replace(month=1, day=1) if period == 'last_60_days': return right_now + timedelta(days=-60), right_now elif period == 'last_90_days': return right_now + timedelta(days=-90), right_now #elif period == 'year_to_date': # return ytd, right_now else: return right_now + timedelta(days=-30), right_now -
Django unable to modify a row in SQL Server with multiple primary keys
I am using Django 3.0, DjangoRestFramework 3.12 and django-mssql-backend 2.8.1 to build a webapp version of a current desktop app that stores everything in a legacy MS SQL Server database. Due to this I am limited to database modifications that don't alter the table structure already in place. I built my Django models using the built-in legacy database model-generator and then made final modifications on my own. I've been following tutorials to build an API to handle data and everyone seems to recommend using DRF. All of my views use ListAPIView, RetrieveAPIView, and RetrieveUpdateAPIView. Now, when I try to build part of the API to allow me to alter settings in one of the tables, I'm running into an error about inserting a duplicate key value. Database Table: dbo.systemDateTimeSettings - LocationID (PK, FK, int, not null) - Setting (PK, nvarchar(50), not null) - Value (datetime, null) Model: class SystemDatetimeSettings(models.Model): location_id = models.OneToOneField(Locations, models.DO_NOTHING, db_column='LocationID', primary_key=True) setting = models.CharField(db_column='Setting', max_length=50) value = models.DateTimeField(db_column='Value', blank=True, null=True) def get_api_url(self, request=None): return reverse("api:datetime-settings-update", kwargs={ 'location_id': int(self.location_id.location_id), 'setting': self.setting }, request=request) class Meta: managed = False db_table = 'SystemDateTimeSettings' unique_together = (('location_id', 'setting'),) Serializer: class SystemDatetimeSettingsSerializer(serializers.ModelSerializer): url = serializers.SerializerMethodField(read_only=True) class Meta: model = SystemDatetimeSettings fields …
