Using django forms with separate models for labels and fields
I apologize in advance if this ends up sounding cryptic... I'm building a site using Django where users can select a topic from a list and then fill out a form that contains questions specific to that topic. I have 2 models: the Topic model is for the different topics and contains the specific questions for each. The Answers model is for the answers that are submitted in the form. The Answers model is linked to the Topic model with a foreign key. I currently have everything working the way that I want it to, but very messily. I am using purely html forms, and each input label is populated with the question text saved in the Topic model. What I am doing is running JavaScript when the form is submitted, querying all the form fields, and then using fetch to send a POST request with all the field text. Then in my views.py, I receive the request, get all the data, and save a new instance of the Answers model. I'm not well versed in form security, other than knowing to use a csrf token. Out of consideration for any SQL injection vulnerabilities, I started doing some research and … -
How to redirect http://127.0.0.1:8000/ to login page if the user is not logged in
In my Django project I am trying to make the http://127.0.0.1:8000/ which is the home page to redirect to the Login in Page if user is not logged in however there is a user who is logged in I want http://127.0.0.1:8000/ to become http://127.0.0.1:8000/username/ I have tried different answers but nothing specific lead to this answer: Here is the login view after login: class LoginView(LoginView): template_name = 'login.html' def get_success_url(self): user=self.request.user.username return f'/{user}/' Here is the login urls: path('accounts/login/', LoginView.as_view(redirect_authenticated_user=True,template_name='users/login.html'), name='login'), Here is the home views: class home(LoginRequiredMixin, ListView): model = Item template_name = 'app/home.html' context_object_name = 'items' Here is the app urls: path('<str:username>/', home.as_view(), name='home'), My question: How to redirect home page to http://127.0.0.1:8000/username/ if user is logged in and if not to login page -
Django tests not isolated when testing authentication
I am testing my authentication with the django.test.Client and two tests cases fail because once I test my test_login_success test case, the other tests fail because the user remains authenticated, even when I am instantiating a new client in the class setUp and even deleting the user in the tearDown. My code: from django.test import Client, TestCase from app.users.models import User class TestLogin(TestCase): def setUp(self): super().setUp() self.email = 'test@test.com' self.password = 'SomeRandomPass96' User.objects.create_user(email=self.email, password=self.password) self.client = Client() def tearDown(self): User.objects.filter(email=self.email).delete() super().tearDown() def test_not_authenticated(self): # success the first time, fails after test_login_success is executed for the first time. user = User.objects.get(email=self.email) assert not user.is_authenticated def test_login_success(self): # always success self.client.post( '/users/login/', {'email': self.email, 'password': self.password} ) user = User.objects.get(email=self.email) assert user.is_authenticated def test_login_wrong_credentials(self): # success the first time, fails after test_login_success is executed for the first time. self.client.post( '/users/login/', {'email': self.email, 'password': 'wrongPassword123'} ) user = User.objects.get(email=self.email) assert not user.is_authenticated -

Django Dynamic URL from Forms
TL;DR - I failed implementing dynamic urls for too long. My plan is: Whenever the form is submitted, it would redirect you to a page (with a pk as the url), that sums up your choices. I'm aware that this was asked multiple times and I was able to implement Dynamic URLs perfectly fine with a new project. Yet, my current one is simply not making any sense to me. I have a simple form with CharField as fields. It renders them from the Models file which states pretty much the same. I added to the Models.py: > task_id = models.AutoField(primary_key=True) The form is inside "hunting.html", and you access it through the navbar: > <a class="nav-link {% if 'hunting' in segment %} active {% endif %}" href="/hunting.html"> My view is quite simple, I recently opted to Class-based (when using function-base it did not work as well): app/views.py class Hunting(LoginRequiredMixin, View): def get(self, request): form = HuntForm() print('Access Hunting') return render(request, 'home/hunting.html', {'form': form}) def post(self, request): form = HuntForm(request.POST, request.FILES) name = request.POST['name'] limit = request.POST['limit'] os = request.POST.getlist('os') mal = request.POST.getlist('mal') my_type = request.POST.getlist('my_type') if form.is_valid(): form.save() print('Hunt information is saved') return redirect('home/index.html') return redirect('home/index.html') app/urls.py: path('', views.index, name='home'), … -
Custom User class, password isn't saved from the form

DJANGO: How can I create a custom User with a OneToOne relationship to Person
I have a custom user model, I would like my CustomUser model to have a OneToOne relationship with the Person model; Since I want to first register persons and then create a username for them, since not all registered people need to have a username.

How oauth works for saving users data?

How to make nginx serve static files from multiple directories for django project?
I have a django project. It has static files in multiple applications, that I can put together by running python3 manage.py collectstatic. All files will be moved to the static folder, which is located in the root folder of my project. Additionally, I have 200GB pictues, located in another folder /var/images/user-profile-images/subfolder/image.jpg. In both cases image url is like so: /static/path-to-image. So in first case I have static folder, in second case I don't have. this is my location block: location ~ ^\/static\/(.*) { try_files /project-root-folder/static/$1 /var/images/user-profile-images/$1; } it is supposed to serve urls /static/style.css and /static/subfolder/image.jpg respectively, but doesn't work in both cases. I have double checked everything many times, searched around stackoverflow, but no answer. Seems it's also not possible to debug this, since nginx is not logging not found cases. Actually, I see django 404 error, so probably it does not even match. -
Django static css doesn't make any change and images don't appear
Django static files are not working in my application, I defined STATICFILES_DIRS, STATIC_URL, and STATIC_ROOT in settings.py: STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = 'static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'social_media') ] and here's base.html: {% load static %} <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" type= "text/css" href="{% static 'style.css' %}"> </head> <body> {% block navbar %} {% include 'parts/navbar.html' %} {% endblock %} {% block content %} {% endblock %} </body> </html> I use this in my pages: {% extends 'base.html' %} {% load static %} {% block content %} <!--stuff--> {% endblock content %} I tried using InPrivate(incognito but MS Edge version) window and nothing changed, I also tried deleting style.css file and making it again and collecting static files again but it also didn't work. -
How can I ensure enough space is left to avoid content moving down the page if a warning message appears?
I have a server-side rendered application (Django) with a login page which provides a username and password field, submit button, instructions for forgotten password and so on. This is what I will call the "main content". Sometimes, there will an extra div above the main content with a message such as "Invalid username or password". I would like it so that if the user submits an invalid login and this message appears, the main content doesn't move. (I'm aware that this will involve leaving a white space above the main content, but there's a lot of blank space on this page anyway so it doesn't matter) I considered rendering <div class="warning-message">Invalid username or password</div> if required and some kind of placeholder <div class="placeholder"></div> otherwise, but I was struggling to style them so that the empty div would always be the same height as the warning message one. I did also consider positioning either the main content or the warning message with position:absolute, but this sometimes leads to overlapping on small screens. -

Django hide password fields on user creation form
I have a custom user model and a form that allows admins to add users without having to go to the admin section. I want hide the password fields and set the password to a random generated string. Then send an email to the new user with a link to reset their password. So far I haven't been able to figure out the first part - hiding the password fields. The form.py: from django.contrib.auth.forms import UserCreationForm, UserChangeForm from .models import CustomUser class AddCompanyEmployeeForm(UserCreationForm): class Meta: model = CustomUser fields = UserCreationForm.Meta.fields + ('email', 'full_name', 'age') the view: from django.views.generic import CreateView, ListView from django.urls.base import reverse from .forms import CustomUserCreationForm, AddCompanyEmployeeForm from .models import CustomUser class SignUpView(CreateView): form_class = CustomUserCreationForm success_url = reverse_lazy('login') template_name = 'registration/signup.html' class AddCompanyEmployee(CreateView): model = CustomUser template_name = 'manage/add_employee.html' form_class = AddCompanyEmployeeForm #success_url = reverse_lazy('directory') def get_success_url(self): return reverse('userprofile_detail', kwargs={'pk': self.object.userprofile.pk}) I have tried a number of approaches including changing the form to class AddCompanyEmployeeForm(UserCreationForm): class Meta: model = CustomUser fields = ('email', 'full_name', 'age') So far the password fields continue to be visible regardless of what I try. Any suggestions? -

Trigger python script with Django user input
I am trying to trigger a pyfirmata script that will load onto an arduino device when a user checks a checkbox on a django view. I am trying to implement some comparison code in my view that will check if user submitted check box is true then trigger pyfirm.py. Background: Py firmata will drive the arduino pins directly without needing an arduino IDE. Should I hard code my pyfirmata in my view or can I trigger a full script some how? Iam using a raspberry pi as a single board computer that is connected to arduino as a device driver. I am considering the pi device as a user. Any tips on this? I have my check box working and i am printing the POST results to the terminal. just need to check if box is true and trigger script some how. Haven't had any luck triggering a script. I see a couple questions related to this but i am curious for pyfirmata specific directions on this. -
