django loading fixture "Cannot save object! The state has been changed since fetched from the database!"
I am loading a fixture to get content into the database while testing. The test case starts like this: class FirstTestCase(TransactionTestCase): fixtures = ['alldata.json'] I've created the fixture using a small version of my huge original database with a lot of content removed; this is also the version of the database i use for testing: if "test" in sys.argv: DATABASES = { 'default': { #the details of my smaller database } } when testing, I get the following error: Problem installing fixture '/path/to/my/fixture/alldata.json': Cannot save object! The state has been changed since fetched from the database! I haven't edited the .json file, how can I get this fixture to load -

The included URLconf '<rest_framework.routers.DefaultRouter object
This is my app route from .views import StudentView from rest_framework import routers router = routers.DefaultRouter() router.register('student', StudentView) and this is my project URLs file and I am trying to include the Student route in it from django.contrib import admin from django.urls import path, include from student_school.urls import router urlpatterns = [ path('admin/', admin.site.urls), path(r'', include(router)) ] But am getting this error django.core.exceptions.ImproperlyConfigured: The included URLconf '<rest_framework.routers.DefaultRouter object at 0x7fddc2abb520>' does not appear to have any patterns in it. If you see the 'urlpatterns' variable with valid patterns in the file then the issue is probably caused by a circular import. -

<HaltServer 'Worker failed to boot.' 3> - Heroku Crash --- Worker failed to boot
Every now and then with my Django project launched on Heroku, it crashes. I know it is a change I am making somewhere but I cannot figure out what I am doing that is causing it. It's not completely random but I set DEBUG = True and turned off collectstatic and it crashed. I don't know if it is totally that or something else that I am doing but I just want to educate myself on it. I'm posting the Heroku log tails below.

Problems using createview on heroku
I was working locally and 3 Create Views worked perfectly for me to upload data. I passed it to Heroku and sadly out of the 3, only one CreateView works for me, any idea what it could be? I already reviewed the code and it is very similar both in views and in the template. The problem is that when I click the save button it doesn't do anything, it doesn't save anything and it doesn't take me to any link, but it seems strange to me that locally it worked quite well and not on heroku models class Carro(models.Model): placas=models.CharField(max_length=255) año=models.IntegerField() marca=models.CharField(max_length=255) modelo=models.CharField(max_length=255) tipo=models.CharField(max_length=255) motor=models.CharField(max_length=255, default='0') vin=models.CharField(max_length=255) color=models.CharField(max_length=255) agente_seguros=models.CharField(max_length=255) compañia_seguros=models.CharField(max_length=255) no_politica=models.CharField(max_length=255) cliente= models.ForeignKey(Clientes, on_delete=models.SET_NULL, null=True) def __str__(self): return f'{self.placas} {self.año}{self.marca} {self.modelo} {self.tipo}{self.motor}{self.vin}{self.color}' \ f'{self.agente_seguros}{self.compañia_seguros}{self.no_politica}{self.cliente}' views class create_carros(CreateView): model=Carro form_class=CarroForm template_name='carros/carros-form-add.html' success_url=reverse_lazy('carros:list_cars') -

Passing OpenAPI specs to Frontend framwork using DRF
The DRF app is very transaction heavy, it has lots of POST endpoints which expect forms. Some of these forms are 30+ input fields long. My plan is to now request the form that is requiered by the endpoint before I render it in the frondend. I got this idea from learning about the OPTION request, it returns a json that looks as following: { "name": "Snippet List", "description": "", "renders": [ "application/json", "text/html" ], "parses": [ "application/json", "application/x-www-form-urlencoded", "multipart/form-data" ], "actions": { "POST": { <------------------------- "id": { "type": "integer", "required": false, "read_only": true, "label": "ID" }, "title": { "type": "string", "required": false, "read_only": false, "label": "Title", "max_length": 100 }, It gets really interesting in the POST section of the json. Here every field that the API expects is listed, with the label, the type and abviosuly the key. But how do I request this data in the frondend. Also, I don't believe the OPTION request is ment for this. That's why I want to use OpenAPI specs for this. I've read a bit in the Django Docs and was able to create OpenAPI specs for my entire website but I somehow need specs that I can request per endpoint. … -

Get latest related item for each item in QuerySet
I have a simple model of an Observation made by a Sensor: class Observation(models.Model): class ObservationType(models.TextChoices): PM25 = 'pm25_kal', 'PM2,5' PM10 = 'pm10_kal', 'PM10' RH = 'rh', _('Relative humidity') TEMP = 'temp', _('Temperature') date_time = models.DateTimeField() sensor = models.ForeignKey(Sensor, on_delete=models.CASCADE) obs_type = models.CharField(max_length=8, choices=ObservationType.choices) value = models.DecimalField(max_digits=6, decimal_places=3) What I want to do, is get a list or QuerySet with the latest Observation of a certain type that should at least have been created within 24 hours, for each sensor. I solved the problem using a model method for my Sensor model and a custom QuerySet for my Observation model, to filter recent observations. class ObservationQuerySet(models.query.QuerySet): def recent(self): return self.filter(date_time__gte=timezone.now() - timedelta(days=1)) def latest_recent_observation(self, obs_type): try: return self.observation_set.filter(obs_type=obs_type).recent().latest('date_time') except Observation.DoesNotExist: return None I can loop over all sensors and get the latest_recent_observation() for each of them, but for larger datasets it is pretty slow. Is there any way to make this more efficient? -

how to update an object when several other related objects get created
I have to add a progress_level field to my User model that shows where does this user stand at the moment so I added a field to the user model like this: progress_level = models.CharField(max_length=25, null=True, choices=USER_PROGRESS_LEVELS) I want this field to automatically update itself whenever an action gets done by the user. for instance, if the user completes their contact info and document info and submit their forms, the progress level should change to [1][0].
