ModuleNotFoundError: no module named <projectname> Django Heroku
Help PLEASE!!! Newbie trying to put Django on Heroku... ~8-( Am I supposed to list my app somewhere else???? I just know it some foolish oversight.... I am trying to set up a Django site on Heroku free tier. It works locally (using Sqlite3) and I got it working on Azure - but after following many howtos for this I cannot get it to work and have found no answers (that worked). I am not great with Git and am pretty new to Django - but I think I have followed all the tutorials guidance. Heroku was set up with the same name as used in Git and is correct in wsgi.py. I have the requirements.txt(below), .gitignore, Procfile (web: gunicorn animalproject.wsgi --log-file -), .env ('DATABASE_URL=sqlite:///db.sqlite3' - just for local and this is in .gitignore) , runtime.txt (python-3.7.10), django-heroku, and settings.py correct I thought... I did install Postgresql per various tutorials and it shows as correct in Heroku. I am trying to use dj-database-url.And I do have a .env file with DATABASE_URL= postgres://@ec2-54-87-34-201.compute-1.amazonaws.com:5432/ Settings.py is: import environ import django_heroku import dj_database_url ... env = environ.Env() # allows use of env("x") environ.Env.read_env() ...

Django get specific users profile
I have a implemented a feature in my blog app that allows you to click on a user and view their profile / posts. I want to display information from the users profile such as the bio and profile picture. I was able to successfully display the username but nothing else. To solve this issue I need to get the specific users profile but I am unsure of the proper way to do this Been playing around with a few methods but haven't had anything work and all of the solutions I have found online are about getting the current user views.py class UserPostListView(ListView): model = Post template_name = 'blog/user_posts.html' # <app>/<model>_<viewtype>.html context_object_name = 'posts' paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) userBio = User.objects.get('bio') #not working return Post.objects.filter(author=user).order_by('-date_posted') models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') bio = models.CharField(max_length=200, null=True) def __str__(self): return f'{self.user.username} Profile' def save(self, *args, **kwargs): super(Profile,self).save(*args, **kwargs) img = Image.open(self.image.path) if img.height > 300 or img.width > 300: output_size = (300, 300) img.thumbnail(output_size) img.save(self.image.path) -
Edit permissions for Django Details View for api calls
I am very new to django and currently trying to generate api calls to localhost:8000/stateapi/id where id is an id for a single "State" object in a json (like 1, 2, etc). It is using token authentication by passing a username and password to the "get-token" endpoint and then using that token for calls to the stateapi endpoint. I mostly followed this tutorial https://scotch.io/tutorials/build-a-rest-api-with-django-a-test-driven-approach-part-2 and keep getting a "detail": "You do not have permission to perform this action." Here are the views where CreateView handles the "localhost:8000/stateapi" endpoint and DetailsView handles the localhost:8000/stateapi/id endpoint. class CreateView(generics.ListCreateAPIView): queryset = State.objects.all() serializer_class = StateSerializer permission_classes = (permissions.IsAuthenticated,IsOwner) def perform_create(self, serializer): """Save the post data when creating a new State.""" serializer.save(owner=self.request.user) class DetailsView(generics.RetrieveUpdateDestroyAPIView): """This class handles the http GET, PUT and DELETE requests.""" queryset = State.objects.all() serializer_class = StateSerializer permission_classes = (permissions.IsAuthenticated,IsOwner) I can't seem to figure out why the authenticated user has permission to access information from CreateView but not DetailsView. Here is the permissions code: class IsOwner(BasePermission): """Custom permission class to allow only bucketlist owners to edit them.""" def has_object_permission(self, request, view, obj): # Our problem is that we do not have a owner property for the object """Return True if … -
Django: Display Count of Ratings in ListView

Creating a multi-file uploader with Django Foreign Key

Two OneToOneFields for the same table are not allowed in Django models

Is there an easy way for someone completely naive to docker and web hosting to set up connectivity to their website?
I am very new to the whole development thing so I apologize for the simpleness of my question. I have been scouring the internet and reading articles and watching videos trying to to this docker/django combo I have going live. Everything I've looked at seems to be intended for people who know somewhat what they are doing. It's just not clicking for me reading the documentation and reading these articles. The leap to actually launching this kind of software is what's getting me. I tried AWS, DockerHub, and a few others. My goal is just to get this little Django app I have going so that I can connect to it from work in the web browser without having my laptop there. I want my coworkers to be able to use it as they are a bit technically illiterate and it really simplifies this one thing that they have to do semi-daily. I hope this is enough pertinent info, but let me know if not. I have two separate docker images. One for MariaDB and the other for Django.

Django Rest Framework specify that email must be unique

However, I can still make the emails the same which I don't want. Is there a way to get it so that I can also tell DRF that I would like the email to have to be unique as well? -

React + DRF API not working when using other device
I have two applications: React frontend (via create-react-app) on localhost:3000 Django backend (mainly django-rest-framework) on localhost:8000 I use JWT for authentication but I don't think that matters in this case. Those two apps interact like this: React app has only two routes available to everyone: login page and register page After logging in, login page sends a request to generate JWT which is saved in localStorage From now on each request has a header with JWT in it - done with axios.interceptors So this is how I log in: async function loginUser(email: string, password: string) { try { const response = await axios.post("/api/token/", { email, password, }); setToken(response.data); return true; } catch (error) { return false; } } It works because I have a following setting specified in my package.json: "proxy": "http://localhost:8000" This is my authRequest function which returns axios object to communicate with the API in an authenticated mannner: const baseURL = "http://localhost:8000/api"; export const authRequest = () => { const axiosInstance = axios.create({ baseURL, timeout: 5000, headers: { Authorization: getAccessToken() ? `JWT ${getAccessToken()}` : null, "Content-Type": "application/json", accept: "application/json", "Access-Control-Allow-Origin": "*", "Access-Control-Allow-Headers": "Origin, X-Requested-With, Content-Type, Accept", }, }); return applyInterceptors(axiosInstance); }; The applyInterceptors function add some interceptors which … -

How can I dynamically create multi-level hierarchical forms in Django?
I'm building an advanced search page for a scientific database using Django. The goal is to be able to allow some dynamically created sophisticated searches, joining groups of search terms with and & or. I got part-way there by following this example, which allows multiple terms anded together. It's basically a single group of search terms, dynamically created, that I can either and-together or or-together. E.g. <field1|field2> <is|is not|contains|doesn't contain> <search term> <-> <+> ...where <-> will remove a search term row and <+> will add a new row. But I would like the user to be able to either add another search term row, or add an and-group and an or-group, so that I'd have something like: <and-group|or-group> <-> <field1|field2> <is|is not|contains|doesn't contain> <search term> <-> <+term|+and-group|_or-group> A user could then add terms or groups. The result search might end up like: and-group compound is lysine or-group tissue is brain tissue is spleen feeding status is not fasted Thus the resulting filter would be like the following. Data.objects.filter(Q(compound="lysine") & (Q(tissue=brain) | Q(tissue="spleen")) & ~Q(feeding_status="fasted")) Note - I'm not necessarily asking how to get the filter expression below correct - it's just the dynamic hierarchical construction component that I'm trying … -

How to create a Parent/Child relationship with Django REST models?
I am new to Django REST and want to basically create a join table like this. One Page (txt doc) can have a parent and child Page. Each and every Page can be a parent and child of multiple other pages. Both the Page Entity and PageToPage Entity have an implemented model & serializer in the backend, where the serializer looks like this: class PageToPageSerializer(serializers.ModelSerializer): parent_page = PageSerializer(many=True, read_only=True) child_page = PageSerializer(many=True, read_only=True) class Meta: model = PageToPage fields = ['pkid', 'parent_page', 'child_page'] When entering the manage.py shell and create a PageToPage object, it just yields empty results: # Create Pages p1 = Page(title="Parent Page 1", text="Once upon a time, there was a young man...", page_of_user=u2) p1.save() p3 = Page(title="Child Page 1", text="Once upon a time, there was a young man...", page_of_user=u2) p3.save() # Create Page Relationships ptp = PageToPage(parent_page=p1, child_page=p3) ptp.save() # Select all Pages print("Created Pages:") ser2 = PageSerializer(Page.objects.all(), many=True) print(ser2.data) # Select all Page to Page relationships ser_ptp = PageToPageSerializer(PageToPage.objects.all()) print("Created Page relationships:") print(ser_ptp.data) Output: >>> Created Pages: >>> [OrderedDict([('pkid', 1), ('title', 'Test Page number 1'), ('text', 'Just some sample text'), ('creation_date', '17.06.2021'), ('page_of_user', UUID('eeec0437-75f2-44ba-935d-96fcb78e38c6'))]), ...] >>> Created Page relationships: >>> {} What am I doing wrong? …
