How to restrict Django user account creation to given usernames / addresses / practical values?
We've set up Django user account creation / login through this tutorial, and we've restricted content to auth'd users only through the likes of {% if user.is_authenticated %} and if request.user.is_authenticated. All works great. But there's still nothing stopping anyone from going to the site and registering an account providing any values for username / email address / password. We want to restrict user account creation to specific usernames / emails / IPs / any practical value. Could we check if a value is in some whitelist by inserting something like if email in ['whitelistedemail@example.com']: somewhere? Something that emails out an invite link? We've found the docs on Permissions and Authorization and many SO questions on customizing functionality for types of users, yet we couldn't find any on restricting account creation itself, so perhaps we're missing something. We could start creating different types of users, but we're wary of getting ahead of ourselves by attempting a more advanced solution before figuring out this basic step. Are we approaching this in the right way? -
Django Dockerfile: the difference between Linux Run/Build dependencies

Django - How to filter queryset of model, using field two table away
I have three models: class Classroom(models.Model): classroom_subject = models.CharField(max_length=100) classroom_code = models.CharField(max_length= 5, default = '00000') teacher = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) student_name = models.CharField(max_length=100) classes = models.ManyToManyField(Classroom, blank = True) class WorkItem(models.Model): classroom = models.ForeignKey(Classroom, on_delete=models.CASCADE) work_description = models.CharField(max_length=500) date_assigned = models.DateField(auto_now_add=True, blank=True) time_assigned = models.TimeField(auto_now_add=True, blank=True) submission = models.ForeignKey(UserUpload, null = True, on_delete=models.CASCADE) I'm trying to return a queryset of WorkItem objects and filter the queryset through self.request.user. The model WorkItem is related to Classroom, and classroom is related to student. I have tried: x = WorkItem.objects.filter( classroom__student = self.request.user ) Basically the problem is how to reference a field two tables away, because from WorkItem, I need to reference Classroom, then from Classroom I need to reference Student. I don't know how to do this. Thanks for reading my question, any help would be greatly appreciated :). -

Is it possible to create a Django model from csv input with non-standardized column names/number of columns
I'm working on a project where the end user will provide a semi-standardized csv input to my program. By semi-standardized, I mean that most columns will always be present, but each csv has the potential to have an extra column or two that is unique to that csv alone. Because of this I don't think it's possible to pre-define an all encompassing Django model (I may be wrong, and would love to be shown otherwise), so my question is: is it possible to update/change the Django model's structure from views.py (or in some other way), based on the csv input file, to capture these non-standard columns and store the uploaded CSV to my db? If not, is there another way to go about solving this problem? -

Django : How do you check if an user has the rights or not to Url
I am a newbee in django. In my website, when the user logs in, he is redirected to a page with a dropdown menu where he has to choose a contract on which he wants to work. After selecting the contract he is redirected to the specific homepage define with a pk value in the url.The pk value comes from the ID of the contract in the database. How can I check by a function or a decorator that the user has the rights to this ID. Because any user could right the numbers in the url and access to the page. Here is my view of the dropdown menu : @authenticated_user def selectcontrat(request) : context = initialize_context(request) form_client = SelectClient(request.POST, user=request.user) if form_client.is_valid(): id_contrat = request.POST.get("ID_Customer") return redirect(reverse('home', args=(id_contrat,))) context['form_client'] = form_client return render(request, 'base/selectcontrat.html', context) Here the views of the home page : @authenticated_user def home(request, id_contrat=None): context = initialize_context(request) return render(request, 'home.html', context) The urls : from django.urls import path from . import views urlpatterns = [ path('home/<int:id_contrat>/', views.home, name="home"), path('', views.loginAD, name="login"), path('signin', views.sign_in, name='signin'), path('callback', views.callback, name='callback'), path('selectcontrat', views.selectcontrat, name='selectcontrat') The model is the relation between a user and a group. which group the user … -
Django complex annotation comparing childrens
I have a DJANGO Profiles model and a Answer model with a foreignkey to Profile Imagine that every Profile will have multiple Answers like lists of integers What I want is to order my queryset by the most similar answers to mine. So I found this method (rmse) to compare arrays: np.sqrt(((list_a - list_b) ** 2).mean()) If the arrays are equals this returns 0 and so on..

Django redis cache cannot access redis cache set outside of django
I'm setting up redis as a docker service and connect to it through django-cache and python redis library. First: from django.http import HttpResponse from django.core.cache import cache def test_dj_redis(request): cache.set('dj_key', 'key_in_dj', 1000) return HttpResponse("Redis testing\n" "- in dj view: {}\n" "- in other: {}".format(cache.get('dj_key'), cache.get('py_key'))) Second: import redis r = redis.Redis( host='redis', port=6379 ) def cache_it(): r.set('py_key', 'key in py', 1000) print(r.get('py_key')) print(r.get(':1:dj_key')) print(r.keys()) If I run both of them first one by refresh the web page related to that django view second one by python cache_it(). In first, I cannot access 'py_key', it will return None. But second, I can see the cache set in django view. Django cache added a prefix to it and turn 'dj_key' into ':1:key_in_dj', but I can access it nonetheless. Also in second, the redis_r.keys() return [b'py_key', b':1:key_in_dj']. The value of the key 'py_key' remained the same, so how come I can't access it through django cache.get('py_key') -

Django project on Cloud Foundry not loading admin interface CSS
I have a simple Django project deployed with Cloud Foundry. The admin interface (the only interface used by my simple project) looks fine when running locally. When deployed, however, the CSS is visibly broken. The URLs for the CSS and JS assets return 404. Other answers to similar questions say that the solution is the collectstatic command. To run this in the context of Cloud Foundry, I type the following (obviously with the real app name and path): cf run-task app-name -c "python app-path/manage.py collectstatic" The output logged from this looks very promising: 128 static files copied to '/home/...path.../settings/static'. Yet, in spite of this apparent promise, the CSS is still broken. FYI, my settings include this: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] STATIC_URL = '/static/' PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(PROJECT_DIR, 'static') -

When I create a class/new course it creates an object of that.Now I am trying to add students/users in a particular course/class object by inviting students or students can enroll using "clasroom_id"(a unique field I used in the model) just like we invite people in google classroom to join classes. How to do that? How to add course material to an individual course I added the models and views of the course object below. models.py class course(models.Model): course_name = models.CharField(max_length=200) course_id = models.CharField(max_length=10) course_sec = models.IntegerField() classroom_id = models.CharField(max_length=50,unique=True) created_by = models.ForeignKey(User,on_delete=models.CASCADE) def __str__(self): return self.course_name def is_valid(self): pass views.py def teacher_view(request, *args, **kwargs): form = add_course(request.POST or None) context = {} if form.is_valid(): course = form.save(commit=False) course.created_by = request.user course.save() return HttpResponse("Class Created Sucessfully") context['add_courses'] = form return render(request, 'teacherview.html', context) def view_courses(request, *args, **kwargs): students = course.objects.filter(created_by=request.user) dict = {'course':students} return render(request, 'teacherhome.html',dict)
