POSTMAN -> DJANGO -- Upload Binary file (jpeg). Can't get it to work no matter what I do
to simplify: curl --location --request PUT 'https://myserver.com/upload' \ --form 'file=@/Users/myname/Desktop/bond.jpg' \ --form 'test=test' It gets to my Django App: class MyUploadView(APIView): parser_classes = [FormParser, MultiPartParser] def put(self, request, **kwargs): print(request.FILES) but gives out: <MultiValueDict: {}> nothing I do work, file is always empty. when I use Content-Type: multipart/form-data it doesn't work as well, and sometimes django would complain there is no boundary -- but any value there gives out the same error. MY GOAL IS SIMPLE: all I want it to upload a file to django and save it to disk on the backend. I cannot believe this i taking all day long with zero results and zero examples online that actually work. -

Django logging errors occuring in admin page
I face the following issue: I want to add a new instance of a model in the django admin page, but I do get an 500 error. Now I want to log all the errors occurring in the admin page to a file. Important details: website running in production, hence I do not get feedback in the browser or the console (since I use Gunicorn). this occurs only for one specific model. this only happens when adding a new instance for that model, not when changing exisiting instance logging in the view does not help, since error occurs within admin page I do not want you to help me debug my django code. I am only interessted for tips and a tutorial on how to log every error occuring no matter if it happens in the admin page or the actual site. I am happy for any tips and suggestions! Thanks! Thanks for any advice! -

PWA serviceworker.js being displayed on startup of website

Custom Django Form - modify cleaned data based on request
This has most likely already been asked before, but I could not figure out the right thing to google. I am creating a simple form for people to fill out a COVID screen for an event.

How can I filter objects in my model to only show those of my ForeignKey user?
Trying to filter objects in my view.py to only show items (in my case Buckets) owned by Users. I implemented the code below in my original Model [my model.py code is at the bottom of post] class PostObjects(models.Manager): def get_queryset(self): return super().get_queryset().filter(status=Bucket.owner) But I'm not sure if that is the correct procedure to list all items? Here is the view.py where I'm trying to filter data by User aka owner. Users should ONLY be allowed to view their own items. (I will deal with permissions later) class BucketList(generics.ListCreateAPIView): queryset = Bucket.objects.all() #INSERT FILTER HERE pass Here is the model I'm referring too. class Bucket(models.Model): options = ( ('personal', 'Personal'), ('social', 'Social'), ) class PostObjects(models.Manager): def get_queryset(self): return super().get_queryset().filter(status=Bucket.owner) owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='buckets') users = models.ManyToManyField(settings.AUTH_USER_MODEL) category = models.CharField(max_length=30, choices=options) name = models.CharField(max_length=35) created = models.DateTimeField(default=timezone.now) slug = models.SlugField(unique=True, blank=True) stock_count = models.IntegerField(blank=True, null=True) stock_list = ArrayField(models.CharField(max_length=6),size=10) objects = models.Manager() postobjects = PostObjects() class Meta: ordering = ('-created',) def total_stocks_calc(self): self.stock_count = Bucket.objects.aggregate(Sum('stock_list', distinct=True)) self.save() def get_absolute_url(self): return reverse("bucket:bucket-view", kwargs={"slug": self.slug}) def __str__(self): return self.stock_list To re-state my question, how can I filter objects owned by users in class BucketList for their private view only?

Django custom user model with password
Can Django use a password field from a legacy db for authentication? I have got all of my models working with my legacy postgresql database. I have implemented the custom user model as documented and switched the login to USERNAME_FIELD = 'email'. When running createsuperuser, I do not get prompted for password.

Create equivalent paths in Django urls.py
I am attempting to create 2 url prefixes that would be equivalent in my app (this is due to some aesthetic user requirements), and am unsure the best way to go about this. The most straightforward option would be to create another set of urlpatterns with the alternate prefix. However, this would be repetitive and make maintenance more difficult. Is there a simpler way to make foo/<str:key>/ equivalent to bar/<str:key> and staff/<str:key>/ equivalent to foo/<str:key>/staff/? Current URLS urlpatterns = [ path('foo/<str:key>/welcome/', views.welcome), path('foo/<str:key>/dashboard/', views.dashboard), path('foo/<str:key>/staff/dashboard/', views.staff_dashboard), ] Desired Patterns urlpatterns = [ # Original paths path('foo/<str:key>/welcome/', views.welcome), path('foo/<str:key>/dashboard/', views.dashboard), path('foo/<str:key>/staff/dashboard/', views.staff_dashboard), # Alternate paths to the same pages path('bar/<str:key>/welcome/', views.welcome), path('bar/<str:key>/dashboard/', views.dashboard), path('staff/<str:key>/dashboard/', views.staff_dashboard), ] -

How to avoid duplicate values from queryset
I am having three models class Records(Model): plan = models.ForeignKey(Plan, on_delete=models.CASCADE, related_name="records_plan", null=True) observation = models.CharField(max_length=255, blank=True) description = models.TextField(null=True, blank=True) rating = models.CharField(max_length=255, blank=True) class Plan(Model): plan_title = models.CharField(max_length=255, blank=True) plan_size = models.ForeignKey(Size, on_delete=models.CASCADE, related_name="%(class)s_size", null=True) description = models.TextField(null=True, blank=True) class Size(Model): value = models.CharField(max_length=255, blank=True) order = models.CharField(max_length=255, blank=True) In this I need to draw a chart of plan based on size of the plan my initial queryset is qs = Plan.objects.values('plan_size__value').annotate( count=Count('plan_size__value'), ).order_by("-plan_size__order").distinct() Using this query i'm able to get a queryset with data and field The same queryset I would like to apply a filter on later stages of my code qs = qs.filter(records_plan__rating = 'low') In this case I am getting the output , but values are duplicating (Example, if a plan having two records my chart need to consider it as a single plan , but here it comes as two plans),how to fix this Or how do I get the distinct value of plan while filtering it with record model -

Select multiple rows from list to perform action [closed]
I have a Table-List which is getting their values from the Database, where each row is a representation of a model in the DB. Now I want to make them selectable (checkbox), to multiple delete or submit entries. As now I can only delete entries by deleting them row for row. I dont have any idea at all how to achieve this, hopefully someone has an directional idea?
