Django: prevent making migrations for some models
Django 3.2.6 I'd like some models not to made migrations at all. Is it possible? I tried: 1. https://docs.djangoproject.com/en/3.2/ref/models/options/#managed class Meta: managed = False 2. class PrimaryReplicaRouter: special_model_names = {'generalsettings', 'generalsettings', } def allow_migrate(self, db, app_label, model_name=None, **hints): if model_name in self.special_model_names: return False return True It doesn't help: migrations are created.It doesn't migrate. But migrations become unnecessarily noisy. I quote from here: https://docs.djangoproject.com/en/3.2/topics/db/multi-db/#allow_migrate makemigrations always creates migrations for model changes, but if allow_migrate() returns False, any migration operations for the model_name will be silently skipped when running migrate on the db. Well, I don't want to make migrations for some models. Is it possible? -

React + Django send raw password in HTTP request, security discussion
I am new to Django and I am working on the user authentication part. I used the Django provided User model, and use auth() and login() method when the user login. I have a question about the password security and hope have some discussion here. When the auth() function hashed the raw password and then compares the username and the hashed password. That means the front end needs to send the password in raw data. (Otherwise, it will be hashed twice). Is it not safe to send the password in raw data? If I want to hash the password in the frontend then send the request to Django, what can I do in this case? -

django let's me save a model correctly via admin but not form/shell
I am having difficulty saving a Django model instance into my db. The instance consists of a FileField, which I think is what is causing the difficulty. My model is as follows: class initial_settings(models.Model): name = models.CharField(max_length=30, unique=True) epsilon = models.FloatField(default = 0.3) document = models.FileField(upload_to='documents/') def __str__(self): return self.name And when I open up a shell, create an instance, and save, I then run the command test = initial_settings(name = 'test1234', epsilon = 3, document = 'doc.csv').save() pd.DataFrame(csv.reader(open(test.document.path, 'r'))) Gives me an error, No such file or directory . But, if I open up the admin console and create an instance, it saves correctly and I am able to load it from shell. In the admin console, I can see that the instance created in shell is not being saved to the correct location ('media/documents') but instead direct to root dir, but I am not sure why. Any assistance is appreciated! P.S: Settings.py MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') -

Django - Fastest way to query multiple primary keys in order to create a list of model attribute and uuid to return?
So I have a functionality that should return a list of a user's followers, with the uuid and follower username. The reason the User username isn't the PK is because I'm using amplify and it returns a UUID for user id. As you can see below I'm just querying for all followers of a user then doing a for loop to get each followers user name and creating a dict with uuid and username that goes into a list. I have concerns this will be pretty slow. Is there a quicker way to do this? Model.py class AbstractBaseModel(models.Model): uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) created = models.DateTimeField('Created at', auto_now_add=True) updated_at = models.DateTimeField('Last updated at', auto_now=True, blank=True, null=True) class Meta: abstract = True def __repr__(self): return f'<{self.__class__.__name__} {self.uuid}>' class User(AbstractBaseModel): username = models.CharField(max_length=255, unique=True) email = models.EmailField(max_length=255, unique=True) class FollowUser(AbstractBaseModel): follower_id = models.ForeignKey(User, on_delete=models.CASCADE, related_name="follower_following") followee_id = models.OneToOneField(User, on_delete=models.CASCADE, related_name="followee_followed_by") View.py @api_view(['GET']) def get_followers(request, followee_id): try: followers = FollowUser.objects.filter(followee_id=followee_id).values_list('follower_id', flat=True) followers_list = list(followers) data = list() for follower_uuid in followers_list: try: username = User.objects.get(pk=follower_uuid).username except User.DoesNotExist: return Response(dict(error=f'follower id: {follower_uuid} does not exist in User model'), status=status.HTTP_400_BAD_REQUEST) data.append(dict(username = username, id = follower_uuid)) response_data = dict(followers=data) return JsonResponse(response_data, status=status.HTTP_200_OK) except FollowUser.DoesNotExist: return … -

Creating a Jira issue through OAuth 2.0 (3LO) app fails with the error {"code":401,"message":"Unauthorized"}
I’m an intern developer and I’m integrating a product with the Jira software (cloud). I’m using python and Django web frameworks for development. I followed the https://developer.atlassian.com/cloud/jira/platform/oauth-2-3lo-apps/ documentation and successfully received the access token. The steps I followed are: Created an OAuth 2.0 (3LO) app in the developer console. Configured permissions for ‘Jira platform REST API’ and ‘User identity API’. I selected the rotating refresh tokens option. Added the callback URL as ‘http://localhost:8000/callback’ Direct user to authorization URL to get the authorization code. In the Authorization URL scope is defined as follows: scope = ['write:jira-work read:jira-user read:me read:jira-work'] As the response receives the code and state variables. Exchanged the code value to the access token. The received response is as follows: {"access_token":"token value appears here","scope":"write:jira-work read:jira-work read:jira-user read:me","expires_in":3600,"token_type":"Bearer"} Successfully received the clould_id using the access token. header = {'Authorization': 'Bearer {}'.format(client.token['access_token']), 'Accept': 'application/json'} response = requests.get('https://api.atlassian.com/oauth/token/accessible-resources', headers=header) Retrieved the public profile of the authenticated user successfully. response = requests.get('https://api.atlassian.com/me', headers=header) When I tried to create an issue, it ends up with the following error: {"code":401,"message":"Unauthorized"}.

why is django running extra queries (session, auth, time)

Utilizing a Django slug, getting a no reverse path error
My apologies if you've already read a previous post I made about my Django slug problem. I cleaned up my old code, and perhaps have a better understanding of what I'm doing but I'm still lost as how to get a URL generated from a slug to work on my main landing page. I'm working on a portfolio. I have a landing page where I'm going to link out to individual detail pages. I'm using get_absolute_url in my models to do this. When testing this out, I can get the link to work on the individual project detail page, but not on the main landing pages. Which is funny, because I don't need these links to work on the individual project pages. My guess is that something in my views is not set up correctly. My views.py is set up like this: from django.shortcuts import render, get_object_or_404, get_list_or_404 from .models import Project def home(request): projects = Project.objects.all() return render(request, 'portfolio/home.html', {'projects': projects}) def individual_project_view(request, project_id): projectpage = get_list_or_404(Project, slug=project_id) return render(request, 'portfolio/project_detail.html',{'projectpage':projectpage}) def project_home(request): portfolioprojects = get_list_or_404(Project) return render(request, 'portfolio/project_detail.html', {'portfolioprojects':portfolioprojects}) And here is my urls.py for the individual landing pages, which are in a separate app. from django.contrib import … -
Django builtin url 'logout' reverse URL is returning a relative path
Been searching but can't find this specific issue. I created a separate app for my user authentication (name: user) and included the URLS using django.contrib.auth.urls. Login works. Logout fails. When using the named view {% url 'login' %} the path is absolute, and works fine (i.e. http://host/user/login). When using the named view {% url 'logout' %} in the same template, it gets a relative path to my displayed app. (i.e. http://host/app1/user/login) Django Directory: - djangoProject - djangoProject - app1 - user Django app settings (djangoProject/settings.py): INSTALLED_APPS = [ 'crispy_forms', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'user', 'app1', ] Django app URLS (djangoProject/urls.py) urlpatterns = [ path('app1/', include('app1.urls')), path('admin/', admin.site.urls), path('user/', include("django.contrib.auth.urls")), path('user/', include("user.urls")) // in case I add custom pages ] User App URLS (user/urls.py - nothing added, as using from django.contrib.auth.urls): urlpatterns = [ ] User App Views (user/views.py - nothing added. using built in django.contrib.auth): Now, in app1/templates/base.html, I use the following: {% url 'login' %} - which generates the URL - http://host/user/login/ {% url 'logout' %} - which generates the URL - http://host/app1/user/logout If I manually enter the URL http://host/user/logout I get logged out and redirected correctly. Any thoughts? Thanks so much!
