What is the correct way to implement Django password history?
I have implemented a solution for checking a new password against the last 5 passwords like so: Created 5 fields in a user profile table to store the encrypted passwords On creating a new user, I stored the initial password in encrypted form in all the 5 fields On reset, I changed the views.py from Lib>django>contrib>auth directory from my virtual environment like so: def form_valid(self, form): #all initial code to get the keys etc goes here newpwd = form.cleaned_data['new_password2'] #get the unencrypted passwords from history p1 = cipher.decrypt(b64decode(user.pwd1)) p2 = cipher.decrypt(b64decode(user.pwd2)) p3 = cipher.decrypt(b64decode(user.pwd3)) p4 = cipher.decrypt(b64decode(user.pwd4)) p5 = cipher.decrypt(b64decode(user.pwd5)) #check if the password is already used and redirect with error message if newpwd == p1 or newpwd == p2 or newpwd == p3 or newpwd == p4 or newpwd == p5: messages.error(self.request, _('New Password should be different from old password')) return redirect('password_change') else: #store the password in the password history user.pwd5=user.pwd4 user.pwd4=user.pwd3 user.pwd3=user.pwd2 user.pwd2=user.pwd1 user.pwd1=newpwd user.save() form.save() messages.error(self.request,'Password Changed Successfully') return redirect('/user/login') form.save() # Updating the password logs out all other sessions for the user # except the current one. update_session_auth_hash(self.request, form.user) return super().form_valid(form) This works fine. But it feels incorrect editing the existing contrib>auth files like this. Is … -
How do I properly type annotate ForeignKey for Django Mixins?
I would like to use this solution to annotate mixins for models. So I need ForeignKey: from django.db import models class MultiplicatorMixin(models.Model): foo: models.ForeignKey def multiply(self, m: int) -> int: return self.foo.value * m Please note that foo: models.ForeignKey works. However, I want the type of the foreign key as well. So I need something like foo: models.ForeignKey[Foo]. Is it possible to also give the information to which type the foreign key belongs? -

Migrating Django app to use online media storage
I have a Django app running on a server. Currently user uploads are stored on the server filesystem. I already know how to set up S3 storage. What is the best way to migrate existing uploads to S3 without breaking the API and having existing uploads still available? These files are served to the front end in two ways: Directly through a /media/path/to/upload endpoint: /media/<path> django.views.static.serve Through a viewset: /api/v1/users/<user_pk>/items/<item_pk>/attachments/<pk>/ project.app.views.ItemAttachmentsViewSet Does the following make sense: Change the storage backend Go through all model objects Save each model object to get the files uploaded Have /media/path go to a new view that will serve the files similar to how ItemAttachmentsViewSet does it. ? Or is there a better way? -

Django signals: Check if the data inside of ManyToManyField is change/updated
how can I check if the objects inside of ManyToManyField is change or updated while still accessing the main Model where the manytomanyfield is placed.

I want to get the Room model where the student is selected at students field. s1 = Student.objects.first() s1.name = "John Doe" s1.save() '''prints the data with Room model on it.''' -
Is there a way to iterate through all the fields in a Django database object and display them through a template HTML?
I have this HTML code for my template HTML file: name : {{object.name}} age : {{object.age}} gender : {{object.gender}} name, age, gender etc are stored in a MySQL database. Instead of listing every field, which is a lot, I want to generalize the code like this: {% for field in object %} {{field.field_name}} : {{field.field_value}} {% endfor %} My problem is that I have multiple tables and each table has lots of fields. I cannot generalize the table. How do I generalize my template the way I've shown in the latter code snippet? -

For login, request provides user details in Django
I am trying to create a Django todo app by using the Django rest framework where I ran into this problem. I am authenticating the user via the rest framework so that I am able to get an authentication token, for the user. My views.py... def login(request): print("\n\n", request, "\n\n") if request.method == "POST": username = request.POST.get('username') password = request.POST.get('password') user = authenticate(username=username, password=password) if user is not None: login(user) response = requests.post("http://127.0.0.1:8000/api/login/", data={"username":username, "password":password}) token = json.loads(response.text).get("token") request.session["token"] = f"Token {token}" request.session.modified = True # r = requests.get("http://127.0.0.1:8000/api/", headers={"Authorization":request.session["token"]}) return redirect("home") else: return render(request, "todo/login.html", {"message":"Your entered credentials are wrong"}) else: return render(request, "todo/login.html") In which I have figured that when my user input is invalid, the request parameter carries the value <WSGIRequest: POST '/login'>. But when the user input is valid the request parameter carries my user details (the value najaaz - my username). This output was figured out using the print statement in line 2. Since it carries my user details I get the following error 'User' object has no attribute 'method', since the line if request.method == "POST": would be invalid then. This is something new for me, and I am a bit unsure of how … -

chartjs datalabels not showing anything with django template
I tried so many time to ask this question but no one was able to help me so I decided to deleted the previous question and reask with taking into considerations the answers that I received. I have this chart created with chartjs, as you can see you can hover over points to see their coordinated or data, I would like to have an option to show them without having to hover. The reason why I want to do this is because I am going to add export to pdf, and it exports whatever it can see on the HTML , and exporting a chart without its values would be unreadable to the end user. Note (I don't know if this matters but I am using django and I did not do any npm installation of datalabels) Another Note : I was told that I have to register the plugin before using it, with Chart.register(ChartDataLabels); but adding it the chart script just causes the chart to disappear. .cann { border: 3px solid darkgrey; padding: 10px; box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24); transition: all 0.3s cubic-bezier(.25,.8,.25,1); width: 650px; height: 250px; margin-left: 3em; } <!-- Required meta tags --> … -

How to render Django UTC time in local time
I have USE_TZ = True enabled in my settings.py file, so dateTime values are stored as UTC. When I want to display these dates/times on a template, they will be displayed in whatever timezone I have set in setings.py with TIME_ZONE = 'America/Toronto'. But what if my users are in different timezones and I want it to automatically change the time based on the users timezone? I found that using javascript I can do : new Date(djangoDate)).toLocaleString() will format the date and time to my timezone, regardless of what I have in TIME_ZONE = 'America/Toronto' But is there a way to do this in python/Django? Everything I have tried, like {% load tz %} relies on TIME_ZONE = 'America/Toronto'. in settings.py. I have also tried: timezone.activate(pytz.timezone('America/Winnipeg')) in my view, which seems to display the dates as intended, but found that this will actually change the UTC value in the database when using forms to update dateTime data, which is behavior I do not want. I want to store in UTC, and render/display in local time, automatically without the user having to tell the application what timezone they are in. Is this possible? -

How to copy staging database to Heroku review app
A similar thread to this one already exists (see link), but I do think that my case is a bit different - my main issue is that heroku.yml's release section doesn't play nicely with app.json's postdeploy script. heroku.yml: ... release: command: - python manage.py migrate image: web app.json: { ... "environments": { "review": { "addons": [ "heroku-postgresql:hobby-dev", ], "scripts": { "postdeploy": "pg_dump $STAGING_DATABASE_URL | psql $DATABASE_URL && python manage.py migrate" } } } } During a deploy, the release from heroku.yml gets executed before the postdeploy script, which introduces a bunch on conflicts when psql is called because the tables already exist. Does anybody know how to handle this? release shouldn't be ignored as it's run on every new release, whereas postdeploy is run only once. But at the time that postdeploy is being run, the database should be empty for psql to succeed without errors. -
