Can't login my users, they don't seem to be registering properly
I'm trying to login the users I registered in my registration view (where I get a 200 code that says POST request was successful) but I get "Unable to log in with provided credentials." when I try to log them in. When I check in the shell with User.objects.all(), I only get my superuser back so I think the users are not being saved to the database. I don't understand why this is happening so if anyone has an idea, it'd be appreciated. Here's the code.

How can I allow a user to upload the template for a landing page for another user in Django?
I have the admin user able to upload via forms a landing page for a selected role (Student, Advisor, Admin) and I want to be able to get it to render properly. Right now, it renders properly the html and the css but prints out in plain text the {{ }}'s and the {% %}'s which isn't helpful. The view for the roles landing pages as of right now sends the plain text html (context['page'] = LandingPage.objects.get(role='adm', live=True)) stored in the database to the html stored in templates which has nothing in it except {{ page| safe}}. -

django-channels: PUT request info not saving when user disconnects from websocket then reconnects
I have a problem. The app in question is basically complete, but there's a bug with the user PUT endpoint to edit the user info. If the websocket is disconnected, the endpoint works well. same if the websocket is connected. But If I edit the profile with the websocket connected, disconnect the websocket and connect it again, the changes I made are reverted. anyone know why? What's also weird is that the websocket is used only in chat, not for profile editing (chat is an entirely different app) Any help is appreciated -

removing default --------- option from radio button rendering in template
I am trying to remove the -------- value in my radio button display. The field is declared like this in models.py my_field = models.CharField(max_length=50, choices=MY_CHOICE, blank=True, null=True) I am using this ModelForm to apply some custom CSS forms.py class MyAppForm(ModelForm): class Meta: model = MyApp exclude = [] def __init__(self, *args, **kwargs): super(MyAppForm, self).__init__(*args, **kwargs) self.fields['my_field'].empty_label = None for i, f in self.fields.items(): f.widget.attrs['class'] = 'custom-class' I have seen this line self.fields['my_field'].empty_label = None suggested in multiple Answers on StackOverflow, but, it seem to have no effect in my setup. I am getting the value of the selected choice using this piece of code in views.py def app_view(request, fk_id): app_value = MyApp.objects.get(my_fk=fk_id) # my_fk is a fk from another model app_form = MyAppForm(instance=app_value) I am rendering this form by simply {% for value, text in my_field.my_field.field.choices %} <li> <input id="{{ value }}" name="{{ app_form.my_field.name }}" type="radio" value="{{ value }}" {% if app_value.my_field == value %}checked="checked"{% endif %}> <label for="{{ value }}">{{ text }}</label> </li> {% endfor %} What could I be doing wrong in this setup that is not removing the default select option, ------? -

I can't use cookies sent by a Django server
I created an authentication API on Django that sends csrf token in the response cookie when you send a request to a login endpoint. But it only works when I make these requests with Postman or directly from the browser: Postman login Postman Profile page access Response from a server to an axios request Here we see that there are no cookies in the browser: Cookies stored in the browser after request But here we clearly can see that server sent me cookies with csrf token and session id.

Django, use timedelta to add follow-up date to an invoice date
I've got this simple model that I'm using to practice various Django stuff: class Receivables(models.Model): agent = models.ForeignKey(Agents, on_delete=models.CASCADE, related_name='invoices') invoice_number = models.CharField(max_length=50) invoice_amount = MoneyField(decimal_places=2, default=0, default_currency='USD', max_digits=11) invoice_date = models.DateField() invoice_due_date = models.DateField() total_invoices = models.IntegerField(null=True) And I'm trying to create a follow-up date that is calculated to be 60 days from the invoice date. As I understand from researching, I need to use 'annotate' on my queryset, and so I tried this first: qry = Receivables.objects.annotate(follow_up_date=Receivables.invoice_date+timedelta(days=60)) And that threw a a TypeError for an unsupported operand for +: 'DeferredAttribute' and 'datetime.timedelta'. I found an anser on StackOverflow (to use an ExpressionWrapper), that I tried to work into my query like this: qry = Receivables.objects.annotate(follow_up_date=models.ExpressionWrapper(Receivables.invoice_date+timedelta(days=60))) But that throws the exact same error. Please help me understand what I'm doing wrong here. -

Stripe PaymentIntent credit card payment form refreshing the page instead of processing
would really appreciate the help. Everytime I hit the submit form on the Sripe credit card form, it simply refreshes the page and attaches the stripe token and card fields onto the URL instead of processing the payment. I checked on the Stripe dashboard, and the payment does not go through. The payment intent item gets captured in the models fine, but the payment status is None, presumably because the form is doing nothing. Previously it was not redirecting anywhere (which is fine, I have a fix planned for that), but the payment was going through on Stripe. After I fixed the form.submit() issue (had to change the button id), now the form is simply refreshing itself. The form html <section class="hero py-5"> <div class="container"> <div class='col-10 col-md-6 mx-auto'> <form id="payment-form"> <div id="card-element" class="form-control"><!--Stripe.js injects the Card Element--></div> <button class="btn btn-success" id="stripe-submit"> <div class="spinner visible" id="spinner"></div> <span id="button-text">Pay now</span> </button> <p id="card-error" role="alert"></p> <p class="result-message hidden"> Payment succeeded, see the result in your <a href="" target="_blank">Stripe dashboard.</a> Refresh the page to pay again. </p> </form> </div> </div> </section> The Javascript: <script src="https://js.stripe.com/v3/"></script> <script type="text/javascript"> var stripe = Stripe(XXXXX); var elements = stripe.elements(); var card = elements.create('card', { style: { base: … -

Django API Deployment to Heroku "ProgrammingError"
Please refer to this thread with a very similar issue that was not solved I created a web API through Django in order to service a mobile app that I am developing. Within that API, I configured an external MySQL database that is hosted on a remote server. The API runs fine locally. I pushed this API to a GitHub repository and deployed it through Heroku using a Heroku app. The app launches successfully, however when I try to access a path which I have defined in my API, for example "/guests" (accessing this path is supposed to collect data from a "guest" table in my external database, and return it), I get an error. From what I can gather, it seems that it's as if I don't have an external database configured. The comments in the thread which I referenced above seem to say the same thing.

How to I send an external POST request to a Django app?
I need to send a POST request to a Django app to update a dictionary that the app references. The urls.py file looks like: from django.conf.urls import url from . import views urlpatterns = [url(r'^post/', views.receive] and the views.py file looks like: from django.shortcuts import render, HttpResponse import json def receive(request): if request.method == 'POST': contents = json.parse(request.body) When I try to send a POST to the url in urls.py with a simple body, I get a forbidden error. How do I structure my code/app to receive and record data from a POST? Is Django able to do this? -

Python - Reactivating my virtualenv for django project
(Beginner) I am working with a virtualenv for a django project using my Macos terminal and Visual Studio Code. Recently, my terminal disappeared where I was running all of my code and I do not know how to reenter my virtualenv or my project that I still have on Visual Studio Code. I have tried everything including: source virtualenv/bin/activate Or, virtualenv/source/activate Or, cd my_project_name and then trying to enter my virtualenv following this step (^) with the commands above. Nothing is working and when I run "python manage.py runserver" it says there is no such file or directory. I am struggling and do not know how to continue my current project on django before getting back to my project and virtualenv. Any help is greatly appreciated! -
How to deal with foreign keys in the model adding form on the admin panel?
I have three based models with Foreign keys relations, defined as follows: class User(AbstractUser): username = None email = models.EmailField(('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] def __str__(self): return self.email class Product(models.Model): id = models.CharField(primary_key=True, max_length=255) user = models.ForeignKey( User, on_delete=models.CASCADE, related_name="products", null=True, blank=True, ) class Viewer(models.Model): id = models.CharField(primary_key=True, max_length=255) product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name="viewers" ) What I want is, instead of having a form for each model registered in the administration panel, to have a single common form, in which I can fill in the id of the models and these are created in the database if they do not exist. For this purpose, I have defined a new model with foreign keys to these fields: class Register(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) viewer = models.ForeignKey(Viewer, on_delete=models.CASCADE) What I would like is for the registration form to have only 3 charfields, one to enter the user's email, one for the product id and the last one for the viewer id. However, when I define a form in the following way: class RegisterForm(forms.ModelForm): user = forms.EmailField() product = forms.CharField(max_length=255) viewer = forms.CharField(max_length=255) class Meta: model = Register fields = ("user", "product", "viewer") …
