Custom template tag and CSRF protection
Django 3.2.6 emails/subscribe.html <form action="{% url 'emails:subscribe_result' %}" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> This works fine: class SubscribeFormView(FormView): template_name = 'emails/subscribe.html' form_class = SubscribeForm success_url = 'emails/thanks/' But this does not: from django import template from django.utils.safestring import mark_safe, SafeString from django.template import Context, Template from django.template.loader import get_template register = template.Library() from emails.forms import SubscribeForm @register.simple_tag def subscribe() -> SafeString: template = get_template("emails/subscribe.html") context = {"form": SubscribeForm(), } result = template.render(context) return mark_safe(result) I get: Forbidden (403) CSRF verification failed. Request aborted. Help Reason given for failure: CSRF token missing or incorrect. Could you help me understand why custom template tag can't be used here? Maybe a request via AJAX can help? ///////////////////////////// -
Foreign key with multiple models?
I am creating ecommerce website. There are multiple categories. For example, phones, computers and others. I created a model for each of them. In OrderItems I want to foreign key each of them.

Django forms.DateTimeField change input type
I want to change forms.DateTimeField input type to "d/m/y H:M". How can I do that? I tried this but didn't work: travel_on = forms.DateTimeField(input_formats='%m/%d/%y %H:%M') Here's my Ticket Model: User = settings.AUTH_USER_MODEL class Ticket(models.Model): from_station = models.CharField(max_length=30) to_station = models.CharField(max_length=30) purchased_on = models.DateTimeField(default=timezone.now) travel_on = models.DateTimeField() customer = models.ForeignKey(User,on_delete=models.CASCADE) def __str__(self): return f"Customer:{self.customer.username},From:{self.from_station},To:{self.to_station},Travel on:{self.travel_on},Purchased on:{self.purchased_on}" My TicketForm: from .models import Ticket from django import forms class TicketForm(forms.ModelForm): travel_on = forms.DateTimeField(input_formats='%m/%d/%y %H:%M') class Meta: model = Ticket fields = ('from_station','to_station','travel_on') -
How can I add new URLS to Django 3.2 under /admin?
I am working on upgrading an old Django project to 3.2. Previously, our urls.py for the main project included the following so that the urls from impersonate were below /admin url(r"^admin/", include(admin.site.urls)) url(r"^admin/impersonate/", include("impersonate.urls")), When I update this code to django 3.2, I don't seem to be able to include any urls beneath /admin. The following code: re_path(r"^admin/", admin.site.urls), re_path(r"^admin/impersonate/", include("impersonate.urls")), does not work, but it does work if I modify the impersonate line to: re_path(r"^impersonate/", include("impersonate.urls")), Basically, I want to preserve all of the impersonate urls to be beneath /admin, if this is still possible. I understand that this does not make them require admin permissions, rather this is just to group all the admin views of the project together. I have seen that I can write a custom ModelAdmin also, but this will still move the urls to under /admin/myapp/mymodel/my_view/. I do not want the extra part of the path mymodel here. -
Azure app service SSH connection refused. not using Docker. Django not installing from requirements
I followed the steps in https://docs.microsoft.com/en-us/azure/app-service/tutorial-python-postgresql-app?tabs=bash%2Cclone&pivots=postgres-single-server#4-deploy-the-code-to-azure-app-service to deploy my Django app to Azure.

How to perform an http post request to a device behind a router using DDNS & Python
For faster prototyping of my code, I would like to provide my laptop address as an endpoint to the http webhook API (Base URL) of the website cloud.thethings.network. For this, I setup a ddns on noip.com and connected my tp-link router with my noip-account. So right now, I have sth. like myneedddns.ddns.com that forwards to my router. I’ve also set port forwarding in my router to access my laptop and reserved a static IP for the laptop: However, I can not provide a format like xxx.ddns.com:801 on thethingsstack. From there I can probably handle how to receive the request with flask or django. How would you approach my goal? -
Unique Class or extend Class or Subclass in Python Django?
Unique Class or extend Class or Subclass in Python Django? In the following situation, I have a feeling I need to ?extend? the Migration class instead of re-stating it in the second module. Or is a child class needed? A goal here: To create a postgres table called venues.

How to obtain a user instance using django rest framework
Perhaps the question is wrongly worded. I created user profile using Django through the following blocks of code: models.py class = Profile (models.Models): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) first name = models.CharField(max_length=50) ••• serializer.py class profile_serializer(serializers.ModerlSerializer) class Meta: model = Profile fields = '__all__' views.py class profile_view(generics.ListCreateAPIView) queryset = Profile.objects.all().filter(user=instance) urls.py urlspatterns = [path('profile', profile_view.as_view(), name='user_profile) I definitely do not know how to implement the filter method to ensure that only the logged in user is retrieved. Or is there a better approach to obtain a specific user? If I use Project.objects.all() without the filter I get all the registered user as expected. But I don't know how to retrieve a particular user. -
Problem with progress upload bar using XMLHttpRequest in Django
I have an issue with a progress upload bar in Django when the site is deployed to Heroku, when I click on the upload button the progress bar shows up at 10% then doesn't change or count up to 100%, when the upload is finished, it redirects as instructed in my views.py , the function runs fine locally, but after deploying to heroku it doesn't work. I think it may be something to do with the deployed url using 'https', but not sure and how to fix it? appreciate any help. custom.js function progressBar() { progressBox.classList.remove('not-visible') cancelBox.classList.remove('not-visible') const upload_data = input.files[0] const url = URL.createObjectURL(upload_data) // console.log(upload_data); const fd = new FormData() fd.append('csrfmiddlewaretoken', csrf[0].value) fd.append('track', upload_data) $.ajax({ type: 'POST', enctype: 'multipart/form-data', data: fd, beforeSend: function(){ }, xhr: function(){ const xhr = new XMLHttpRequest(); xhr.upload.addEventListener('progress', e=>{ // console.log(e); if (e.lengthComputable) { const percent = (e.loaded / e.total) * 100; // console.log(percent); progressBox.innerHTML = `<h5 style="text-align:center;">${percent.toFixed(1)}%</h5> <div class="progress" style="height: 30px;"> <div class="progress-bar bg-success" role="progressbar" style="width: ${percent}%" aria-valuenow="${percent}" aria-valuemin="0" aria-valuemax="100"></div> </div>` } }) cancelBtn.addEventListener('click', ()=>{ xhr.abort() progressBox.innerHTML="" cancelBox.classList.add('not-visible') window.location.reload(); }) return xhr; }, success: function(response){ // console.log(response); uploadForm.reset() cancelBox.classList.add('not-visible') }, error: function(error){ console.log(error); }, cache: false, contentType: false, processData: false, }) } -

Granting access to other class views upon successful authentication Django REST

Django Rest Framework request unauthorized on all but one address
I'm trying to access django hosted at 192.168.x.x:8000 on a React frontend server on port 5002, when attempting to access the frontend with localhost, 127.0.0.1 or ip's outside of the home network, it gives following result in console: Unauthorized: /api/any_endpoint HTTP POST /api/any_endpoint 401 [0.03, 127.0.0.1:12345] However when accessing trough 192.168.x.x:5002, it just works. the /admin/ endpoint seems to work no matter the ip address (ip_address:8000), so it's either django-rest-framework or React that is causing this issue. I have no idea where to start debugging this, so any comment on what I should check would be appreciated -

Is it possible to reorder the content_panels in Wagtail admin?
I am creating a Wagtail application where some models inherit fields from a base model. Unfortunately, these base fields are always displayed first in the form generated by Wagtail. For example: class BaseModel(models.Model): some_attribute = models.TextField() class Meta: abstract = True content_panels = [ FieldPanel('some_attribute'), ] @register_snippet class ChildModel(BaseModel): title = models.TextField() content_panels = Page.content_panels + [ FieldPanel('title'), ] In Wagtail admin in the ChildModel editor, some_attribute would be displayed above title now, which is not very intuitive to users. Is there a way to change this behaviour? -

Django: Add objects.all.count() to aggregate?
I've been searching how to add X.objects.all().count() result to an existing aggregate logic.
