How is this possible that the same serializer produces different results in Django?
I am facing a rather annoying issue than a difficult one. The problem is the following: a given djangorestframework ModelSerializer class called UserSerializer serializes the authenticated user instance with proper image result from the model's FileField attribute when calling some generic API view of djangorestframework, and using the exact same serializer, the image path receives a domain address by default Django version: 4.2.2, Django REST Framework version: 3.14 What I do want to receive in output: the path of the stored file as mentioned in Django documentation (MEDIA_URL is 'media/'), without the localhost domain appended to it. The below image shows that in the RootLayout, I receive the correct path starting with /media/etc. so I append domain address from environmental variable depending on mode, while in UsersLayout, each user gets my MANUAL appended domain and an automatic one from somewhere. This is my urls.py from django.urls import include, path from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView from .views import * urlpatterns = [ path('change-password/<int:pk>', UserChangePasswordView.as_view(), name='auth_change_password'), # ---- Untestable path('languages/', LanguagesL.as_view()), # ----------------------------------------------------------- Tested path('password_reset/', include('django_rest_passwordreset.urls', namespace='password_reset')), # ----- path('payment/barion/ipn/', PaymentBarionIPN.as_view()), # -------------------------------------------- Untestable path('payment/barion/start/<int:pk>', UserSubscriptionCreateStart.as_view()), # ----------------------- Untestable path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), # ---------------------------- path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), # --------------------------- path('user-factor-relation-strategies/', UserFactorRelationStrategiesLC.as_view()), # … -
The Spotify API callback url has '#' in it instead of '?' how to access parameters in python django
I am using the Implicit grant authorisation (1 of 3) types of authorisation provided by Spotify. The callback url looks something like this http://localhost:8000/callback/#access_token=BQDRRPQ1Nulwcxx...mFNtnTsVUNlkCg&token_type=Bearer&expires_in=3600&state=NtiLgMVtLPx926Ay If it was http://localhost:8000/callback/**?**access_token Then I am able to obtain the query parameters using request.GET in my view, but since it has #, request.GET returns empty dictionary. I also tried request.build_absolute_uri(), but it returns just http://localhost:8000/callback/ Here is how my view looks def callback(request, format=None): print(request.GET) if "access_token" in request.GET: print(request.GET["access_token"]) return HttpResponse("Callback") I was expecting request.GET to have the access_token, expires in and the parameters that are in the uri, but I'm getting empty dict. -
Best approach for implementing configurable permissions and roles in Django
I'm working on a Django application and I need to implement configurable permissions and roles. I want to be able to add new roles and associate multiple tasks with each role for specific modules in my Django app. What would be the best approach to achieve this? I would like to have the flexibility to define different roles with specific permissions and assign them to users. Additionally, I want to be able to manage these roles and permissions easily, preferably through my application not django admin. Any insights, recommendations, or examples of how to implement this functionality in Django would be greatly appreciated. Thank you! -
can't find the object in discount system in django

Any ideas how can I export schemas of all the django model's inside a django project into an external format?
I got a requirement from my manager that they require a generic python script that export schemas of all the model present in the django project into excel. Generic because we want to do the same for multiple microservices running on django in our company. Each row in excel is supposed to contain infromation about field in that model. Each model is supposed to be represented in new sheet. I can't seem to figure out what would be a good way to do this. One approach I can think of is using recursion to iterate inside all the files inside the codebase and look for files names like models.py and iterate inside of them to find different classes and extract info like field type, constraints, max length/size, nullable or not, etc. but not sure if this would be a good approach because edge case handling would be hard in the case I think. -
How to change SpectacularSwaggerView's authentication_classes in drf_spectacular?
I have a class that inherits from SpectacularSwaggerView. When I call that view, it shows two authentication methods. basicAuth and cookieAuth. I want to use a custom authentication or maybe use no authentication at all. but when I set authentication_classes attribute like this: class CustomSpectacularSwaggerView(SpectacularSwaggerView): authentication_classes = [ CustomAuthentication, ] it shows the same two authentication methods. How can I change that? -

How to make a web app running on a local server secure?
I wish to create an app using Django, which users can use on their respective local networks. I want to make this secure, and I have trouble finding a way. Most answers point to using self-signed certificates on the server followed by installing certificates on each individual device on the network. However, this might be complicated and too much effort for the users, who may not be so tech savvy. Is there a simpler, cleaner way of making this app secure within the local network? Something I can automate as well. -

Issue with Loading HTML Template After Sending Email in Django
I'm working on a Django project where I need to send an email after a form submission. I have implemented the email sending functionality using the smtplib module. The email is sent successfully, but after that, I'm unable to load the corresponding HTML template (delivery_email_success.html). Here's the relevant code in my view: def enviar_email(request): if request.method == 'POST': # Process data and prepare the email try: # Email setup and sending # ... server.quit() except smtplib.SMTPException as e: return render(request, 's3_error.html') print('Now rendering the success') return render(request, 'delivery_email_success.html') else: return HttpResponse(status=405) And here's the HTML part that submits the form and calls this function: const emailForm = document.getElementById('email-form'); emailForm.addEventListener('submit', (event) => { event.preventDefault(); const visibleRows = document.querySelectorAll('.result-row'); const data = []; visibleRows.forEach(row => { const rowData = { title: row.querySelector('td:nth-child(2)').textContent, catalog: row.querySelector('td:nth-child(3)').textContent, folder: row.querySelector('td:nth-child(4)').textContent, assets: row.querySelector('td:nth-child(5)').textContent, package: row.querySelector('td:nth-child(6)').textContent, sk: row.querySelector('td:nth-child(7)').textContent }; data.push(rowData); }); const emailBody = tinymce.activeEditor.getContent({ format: 'html' }); const formData = new FormData(); formData.append('email_body', emailBody); formData.append('data', JSON.stringify(data)); const csrfToken = document.querySelector('input[name="csrfmiddlewaretoken"]').value; formData.append('csrfmiddlewaretoken', csrfToken); fetch("{% url 'email_delivery' %}", { method: 'POST', body: formData }) .then(response => response.json()) .then(result => { // Manejar la respuesta del servidor }) .catch(error => { // Manejar errores }); }); I have verified that … -
How to pass Ajax POST request with GeoJSON or simply JSON data in Django view?
I am learning how to use jQuery Ajax and how to combine it with my Django project. My Django template comes with a JS source that adds a Leaflet EasyButton to my map with an Ajax POST request to pass some JSON data that is then processed on the Django side: // Create a button to process Geoman features var btn_process_geoman_layers = L.easyButton('<img src="' + placeholder + '" height="24px" width="24px"/>', function (btn, map) { var csrftoken = jQuery("[name=csrfmiddlewaretoken]").val(); function csrfSafeMethod(method) { return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function (xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); // Retrieve all Geoman layers var geoman_layers = map.pm.getGeomanLayers(true).toGeoJSON(); // Process only layers that are feature collections if (geoman_layers["type"] === "FeatureCollection") { // For every feature (e.g. marker, polyline, polygon, circle) for (feature_idx in geoman_layers["features"]) { var feature = geoman_layers["features"][feature_idx]; // pass the feature using Ajax to Django switch(feature["geometry"]["type"]) { case "Polygon": console.log("Polygon"); $.ajax({ url: "", data: { "feature": feature }, datatype: "json", type: "POST", success: function (res, status) { //alert(res); alert(status); }, error: function (res) { alert(res.status); } }); break; default: console.log("Other feature: " + feature["geometry"]["type"]); break; } } } }); btn_process_geoman_layers.addTo(map).setPosition("bottomright"); Currently the data is all features of … -
Django - Includes with blocks inside?
How would you go about creating an include which takes HTML such as templates with blocks? The idea being to pass some blocks into a reusable component e.g. {% include 'banner.html' %} {% block text %} Christmas Sale! {% endblock %} {% block bodyCopy %} When checking out apply the <underline>discount</underline> code <span>F5000</span>! {% endblock %} {% end include %} This would allow you included component to take these different blocks and render as expected e.g. <header> <h1>{% block text $}</h1> <div> <p> {% block bodyCopy %} </p> </div> </header> Symfony has a similar concept called "embeds" -> https://twig.symfony.com/doc/2.x/tags/embed.html -

Django 4.2 : `receiver` Decorator Does Not Receive Signal
I am experimenting with Django Signals. In the documentation, it is written that there are two ways to connect a receiver to a signal. Using Signal.connect method Using receiver decorator Here's what I have implemented: # models.py from django.db import models from django.dispatch import receiver from .signals import demo_signal class Demo(models.Model): demo = models.CharField("demo", max_length=50) def send_signal(self): demo_signal.send(self) print('signal sent') def connect_receiver(self): demo_signal.connect(signal_handler, sender=self) @receiver(demo_signal, sender=Demo) def signal_handler(**kwargs): print('signal handled') # signals.py from django.dispatch import Signal demo_signal = Signal() However, when I call send_signal method, I don't get signal handled printed out unless I call connect_receiver method first. In [1]: demo = Demo.objects.get(pk=2) In [2]: demo Out[2]: <Demo: Demo object (2)> In [3]: demo.send_signal() signal sent In [4]: And Interestingly enough, after implementing pre_delete_handler as follows, without connecting, calling delete method does call pre_delete_handler @receiver(pre_delete, sender=Demo) def pre_delete_handler(instance, **kwargs): print(instance, kwargs) print('pre delete') Receiver does receive the signal without sender argument: @receiver(pre_delete) def pre_delete_handler(instance, **kwargs): print(instance, kwargs) print('pre delete') But how can I make it listen to a specific Model? Why does sending signal does not call its receiver(decorated signal_handler) in my case? -
