Recommendations on setting up models for Django social media app
I'm working on a personal social media project. Every user has a profile. --Profile model-- from django.db import models from django.contrib.auth.models import User from PIL import Image class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') background_image = models.ImageField(upload_to='profile_background_pics', blank=True, null=True,) bio = models.CharField(max_length=200, help_text="200 characters or less") In the profile, I want to have the option for the user to list all the tech stacks (programming languages and frameworks) that they work with and their level for each. Example pseudocode..: @testuser - Tech Stacks model - { Programming Languages: [Python (Intermediate), Java (Noob)], Frontend: [HTML (Intermediate), CSS (Intermediate), JS (Intermediate)], Frameworks: [Django (Getting there..)], Devops: [AWS (Noob), Heroku (Noob)], and so on... So each profile (since profile has OneToOne with contrib.auth.user) will have a tech stack model. The tech stack model will have multiple categories (languages, frameworks, etc). Each category has multiple objects. And each object will have user's level of proficiency. So if I query user.tech_stacks then it should return something like above. And user.tech_stacks.programming_languages should return [Python (Intermediate), Java (Noob)], I should also be able to query all the users that are Python (Intermediate) and Python (Advanced) Thanks for your help.. not really sure where to … -
How to call model method from serializer
I have method inside model: def has_midterm_contracts(self): """ Returns True if midterm contract has uploaded :rtype: boolean """ return MidtermContractFile.objects.filter( reservation_id=self.pk ).exclude( Q(attachment__isnull=True) | Q(attachment__exact='') ).exists() and how can I call it from serializer?

Django + Graphene + DjangoModelFormMutation : dissociating create and update
I am using a DjangoModelFormMutation from Graphene-python to expose a generic mutation for a model, like so : from graphene import Field from graphene_django.forms.mutation import DjangoModelFormMutation from django.db import models class Pet(models.Model): name = models.CharField() legs = models.PositiveIntegerField() class PetForm(forms.ModelForm): class Meta: model = Pet fields = ('name', 'legs') # This will get returned when the mutation completes successfully class PetType(DjangoObjectType): class Meta: model = Pet class PetMutation(DjangoModelFormMutation): pet = Field(PetType) class Meta: form_class = PetForm Then in my schema file, I register the mutation like this : create_pet = mutations.PetMutation.Field() update_pet = mutations.PetMutation.Field() This works, but there are two desired behaviors I can't achieve this way : Have two different mutations : one for create that can only create and not update, and one for update that can only update, and not create. Have the update mutation work partially as well , i.e only updating the client-provided fields. How can I achieve the desired behavior ? -

My django project is missing a lot of defaults and installed packages are not working
When I make my django app there is typically a default sqlite3 that comes with it but for some reason it does not show up so I created a database in the MySQL workbench and then in my settings.py I made sure to add the relevant info. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'nameofDB', 'USER': 'root', 'PASSWORD': 'mypassword', 'HOST': 'localhost', 'PORT': '3306', } } In my virtual environment 'env' after activating it I made sure to install everything django, django-admin, pip. The name of my project is 'studybud' and the directory is: C:\Users\User\Desktop\studybud After making my project, I worked on it for a little and checked how the html was rendered so it was activted and I ran the server but after I left it alone for a while my powershell froze so i simply exited out of everything. Not sure if this affects my current problem. I tried opening my project again but now I get this error: in my virtual environment i did make sure to install mysqlclient before creating the mysql database but as you see its installed in a completely different directory which is the global one. although i would have thought the python … -

Store Django filter_backends search keyword
I want to store the keyword that filter_backend uses to search. This is the class being used. class SearchListView(generics.ListAPIView): queryset = TrainingDetail.objects.all() serializer_class = TrainingDetailSerializer filter_backends = [filters.SearchFilter] search_fields = ['^course_name'] The URL being called is: http://localhost:8003/api/company/search/?search=Danphe&ordering=-created_date So, basically I want to store the word Danphe. How can this be achieved ?
