Value Error: Cannot query "post": Must be "UserProfile" instance
I am getting the Value Error: Cannot query "post": Must be "UserProfile" instance when I make a get request to call PostListView.as_view(). Here is my model.py : from django.db import models from django.contrib.auth.models import User class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) username = models.CharField(max_length=30) first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) email = models.EmailField() password = models.CharField(max_length=100) def __str__(self): return self.user.username class Post(models.Model): user = models.ForeignKey(UserProfile, on_delete=models.CASCADE) title = models.CharField(max_length=100) text = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.title views.py : class PostListView(ListAPIView): serializer_class = PostSerializer permission_classes = [AllowAny] def get_queryset(self): """Returns only the object related to current user""" user = self.request.user return Post.objects.filter(user=user) Also, I want a Foreign key relationship exists between User and Post on Model-level, not on the Database level. -
Save .xlsx file to Azure blob storage
I have a Django application and form which accepts from a user an Excel(.xlsx) and CSV (.csv) file. I need to save both files to Azure Blob Storage. I found it to be trivial to handle the .csv file with the following code: from azure.storage.blob import BlobServiceClient blob_service_client = BlobServiceClient.from_connection_string(os.getenv('STORAGE_CONN_STRING')) blob_client = blob_service_client.get_blob_client(container="my-container-name", blob=form.cleaned_data.get('name_of_form_field_for_csv_file')) blob_client.upload_blob(form.cleaned_data.get('name_of_form_field_for_csv_file'')) However, I've been unable to figure out how to save the .xlsx file. I--perhaps somewhat naively--assumed I could pass the .xlsx file as-is (like the .csv example above) but I get the error: ClientAuthenticationError at /mypage/create/ Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. I found this SO Answer about the above error, but there's no concensus at all on what the error means and I've been unable to progress much further from that link. However, there was some discussion about sending the data to Azure blob storage as a byte stream. Is this a possible way forward? I have also learned that .xlsx files are compressed so do I need to first decompress the file and then send it as a byte stream? If so, has anyone got any experience with this who … -
Why do I get TCP/IP error when trying to create DB in my Lambda?
So I'm trying to deploy my Django project using lambda, with zappa. I'm using MySQL for DB engine. Now after doing some research, I realized that I needed to create a custom Django command to create DB, since I'm using MySQL. So I created crate_db command, zappa updated, then ran zappa manage dev create_db.

How to populate OneToOne field from template side in django?
I am working on a small django-python project which has two models "staff_type" and "staff". In the staff_type model, only designation and date fields are populated. And in the staff model, there is OneToOneField relation of staff_type. Means whenever a user want to add staff first he/she will have to add staff_type and then in the staff module, user will choose the staff type (designation) from a select menu in which all the staff_type are shown respectively. Now, whenever a user select any designation (staff_type) and fill the entire form, I want to store the selected staff_type id in the staff model/table. Note: I have tried this from django admin, and it works perfectly but I want to do the same work in my own designed templates. Modles.py class staff_type(models.Model): designation = models.CharField(max_length=50) salary = models.IntegerField() datetime = models.DateTimeField() entrydatetime = models.DateTimeField( auto_now=False, auto_now_add=False) class staff(models.Model): staff_type = models.OneToOneField(staff_type, on_delete=models.CASCADE) firstname = models.CharField(max_length=50) lastname = models.CharField(max_length=50) fathername = models.CharField(max_length=50) city = models.CharField(max_length=50) country = models.CharField(max_length=50) state = models.CharField(max_length=50) zip = models.IntegerField(blank=True) address = models.CharField(max_length=100) contact =models.CharField(max_length=20) cnic = models.CharField(max_length=14) photo = models.ImageField() cv = models.ImageField() otherfiles = models.ImageField() views.py def add_staff_type(request): if request.method == 'POST': designation = request.POST.get('designation') salary = … -

HOW TO CREATE FILTERED DROPDOWN IN DJANGO INLINE ADMIN FORM
I am seeking to add a dropdown to an inline form in DJANGO based on the user selection. I require a PYTHONIC solution no jquery or javascript please. I have read two approaches. The first being to create a second form and override the default formset and altering the init function. The second approach to make use of the formfield_for_foreignkey option on the inline. Neither work because I can't get the context data of the form. The use-case is that I need to grab a field on the form. I then wish to use that variable to a related model variable. In have uploaded a screen-shot here of the OrderItem admin form. I wish to grab the "PRODUCT" line on the orderitem. Using that instance of the PRODUCT I then want to access the "packaging" variable of that product instance. The issue I run into is that neither option described above provides easy access to the form values. Code is below: RELEVANT MODELS class OrderItem(models.Model): rx_written = models.DateField(default=datetime.date.today) order = models.ForeignKey(Order, related_name='items', on_delete=models.CASCADE) product = models.ForeignKey(Product, related_name='order_items', on_delete=models.CASCADE) doctor = models.ForeignKey(Practitioner, on_delete=models.CASCADE, blank=True, null=True) pet = models.ForeignKey(Pet, on_delete=models.CASCADE, blank=True, null=True) price = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) tax = models.DecimalField(max_digits=10, decimal_places=2, … -

django filtering optimization
I have a large database and want to filter it based on some optional values from user.

How do I create a bidding system using django?
I am currently interested in making a website that functions similar to freelancer.com. In the platform, I want to have two types of users: employers and employees. When an employer posts a job using a django model form, for example, someone looking for article writing services, it becomes visible to employees to bid. When the employer picks one employee, the job becomes invisible to other employees. It becomes a private communication between the employer and the employee. I am stuck in creating the bidding system. I don't know which django (python) function to use for bidding to display all the functions I have stated. I can so far create a job django model and employer forms to post the jobs to the available list of jobs on the website. I don't know what to do next for employees to start bidding on the job. I also want to know the python function I can use so that when the order is marked completed, the employee can no longer upload new files. Please advise. -
How to reconcile shared applabel in two third party apps in django?
I have a large django project I am working on, that is largely based around the wagtail CMS. I recently added the django-wiki app to my project, and ran into issues running makemigrations, getting the error: "Application labels aren't unique, duplicates: sites " It seems both wagtail and django-wiki have apps and applables called 'sites', which is causing a conflict. Given that these apps are not my apps, renaming them as though they were would seem like a bad approach, causing issues whenever I were to upgrade. What is the correct approach to deal with this problem without breaking the packages? -
Custom User Model with multiple Unique id - Django RestFramework
Hi StackOverFlow buddies, I have created a custom User model for my project and would like to register the Users with Restframework.

Issue connecting to secure websocket using Django/Nginx/Daphne
Having an issue using secure websocket (wss) with django, Nginx, Gunicorn, and daphne. My site is hosted through cloudflare which provides the SSL/TLS certificate. I'm using a linux socket in /run/daphne/daphne.sock, where I gave the user 'ubuntu' ownership of the daphne folder. The websockets work fine locally when it is not secured. When I tried hosting on my EC2 instance, I get the error- sockets.js:16 WebSocket connection to 'wss://www.mywebsite.com/ws/sheet/FPIXX8/' failed: Then it keeps trying to reconnect and fail again. It never sets up an initial connection since I don't get a ping.

How to dynamically filter with get_queryset on one of many queries based on if-logic using gt (greater than), lt
I have 3 dropdown boxes that allow the user to pass a parameter (1), operator (2), criteria (3) e.g "price (1) greater (2) than 200 day simple moving average (3)". I am overriding the get_queryset function from my views.py file and testing with user entering the query above into the dropdown boxes. The outcome I am seeking is simply to be able to catch all of the possible combinations in if-statements and only return the relevant filtered query that matches the 3 conditions selected.
