CORS Headers not Working ony With One Specific Endpoint on Django Rest
I have a django 1.10 app with django-cors-headers version 2.0.2. I have set up the settings like this: ALLOWED_HOSTS = ['*'] CORS_ORIGIN_ALLOW_ALL = True INSTALLED_APPS = [ ... 'corsheaders', ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] I have a frontend server on localhost:8080. When I use my local server everything works fine. But when I try to hit my staging server on AWS I get: Access to fetch at 'MY SERVER URL' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. However, the weird thing is that it only happens on one specific endpoint. All the other endpoints work fine on staging server. The endpoint is a basic put() method from a ModelViewSet from the Django Rest Framework. I've tried tweaking the settings in every possbile way I can imagine but I cannot make it work with this endpoint. The endpoint is this one, specifcally the PUT methods is what's throwing the CORS error: class StudentProfileModelViewSet(viewsets.ModelViewSet): queryset = StudentProfile.objects.all() serializer_class = StudentProfileSerializer filter_backends = ( … -
Django rendering context to a header template?
Here is my main.html, i am currently including the header and the footer {% include "store/header.html" %} {% block content %} {% endblock content %} {% include "store/footer.html" %}``` my header.html sample: this is where I am trying to render my cart <div class="shopping__cart"> <div class="shopping__cart__inner"> <div class="offsetmenu__close__btn"> <a href="#"><i class="zmdi zmdi-close"></i></a> </div> <div class="shp__cart__wrap"> {% for item in items %} <div class="shp__single__product"> <div class="shp__pro__thumb"> <a href="#"> <img src="{{item.product.imageURL}}" alt="product images"> </a> </div> <div class="shp__pro__details"> <h2><a href="product-details.html">{{item.product.title}}</a></h2> <span class="quantity">QTY: {{item.quantity}}</span> <span class="shp__price">${{item.product.price|floatformat:2}}</span> </div> <div class="remove__btn"> <a href="#" title="Remove this item"><i class="zmdi zmdi-close"></i></a> </div> </div> {% endfor %} </div> <ul class="shoping__total"> <li class="subtotal">Subtotal:</li> <li class="total__price">${{order.get_cart_total|floatformat:2}}</li> </ul> <ul class="shopping__btn"> <li><a href="cart.html">View Cart</a></li> <li class="shp__checkout"><a href="checkout.html">Checkout</a></li> </ul> </div> </div> I'm trying to render the items to my cart. here is my view: def header(request): category = None categories = Category.objects.all() products = Product.objects.all() if category_slug: category = get_object_or_404(Category, slug=category_slug) products = products.filter(category=category) data = cartData(request) cartItems = data['cartItems'] order = data['order'] items = data['items'] context = {'items':items, 'order':order, 'cartItems':cartItems, 'categories':categories, 'products':products, 'category': category} return render(request, 'store/header.html', context) but I'm not sure how to render it since it's just a header. perhaps I should approach it differently in views. -
Django MFA query
I have a button within my application which is visible to authenticated users (not general public). That button is used to download data to excel. I want to apply extra authentication on that button so that my superuser gets notification before download. I thought of implementing Django MFA so that that authentication code will go to my superuser. But I am stuck at a logic as to how to tie my MFA to this specific button click as oppose to general site authentication. Can you please guide? -
Django - [Errno 13] Permission denied - Win10
I am currently trying to install and set-up Django. I am using windows 10 and python 3.9. When i run pip install django I get the following error: ERROR: Could not install packages due to an EnvironmentError: [Errno13] Permission denied: 'c:\\python39\\Scripts\\django-admin.py'. From reading other questions, adding --user to the command works. However, the command django-admin is still not recognised. Any ideas on how to fix the error? -

Django easy-thumbnails getting weird naming with duplicate extensions
I'm using easy-thumbnails, the original file is saved correctly but the thumbnails are being saved with a duplicate file extension: File.jpg File.jpg.100x100_q85.jpg I would like the thumbnails to be named like this: File.100x100_q85.jpg My model looks like this: def image_filename(instance, filename): folder = 'posts/image' _, ext = os.path.splitext(filename) new_name = str(instance.id) + ext return os.path.join(folder, new_name) class Post(models.Model): name = models.CharField(max_length=255, unique=True) image = ThumbnailerImageField(upload_to=image_filename, null=True, blank=True) Since im using Django Rest Framework I created a serializer following this post: Django easy-thumbnails serialize with Django Rest Framework class ThumbnailSerializer(serializers.ImageField): def __init__(self, alias, *args, **kwargs): super().__init__(*args, **kwargs) self.read_only = True self.alias = alias def to_representation(self, value): if not value: return None url = thumbnail_url(value, self.alias) request = self.context.get('request', None) if request is not None: return request.build_absolute_uri(url) return url Does anyone know how I can get the correct naming on my thumbnails?

How can I add an auto increment field in a model based on total count of objects with same field value?
I'm new to the whole Django thing and a bit lost. Sorry if the title is a bit confusing I'll try to clear things out. So basically I have two models (Folder and Document). A Document can have a single Folder as one of its fields using a Foreign Key. Now I have another field in Document that needs to get the value of the total Document objects that share the same Folder and increase by one. I've tried things I read on the docs (aggregation, F() objects, overriding model's save() function) as well as some answers is read here but didn't manage to get it right so I'm posting to get some help. Below is my models.py file with the two models and some comments for better understanding. class Folder(models.Model): category = models.IntegerField() subCategory = models.IntegerField() name = models.CharField(max_length= 50) desc = models.TextField() class Document(models.Model): folder = models.ForeignKey(Folder, on_delete=models.CASCADE) date_created = models.DateField() date_added = models.DateTimeField() #The field below needs to sum all Document objects that share #the same folder value in the database + 1 and set it as its default value f_no = models.IntegerField(default=lambda: Document.objects.aggegate(Count('folder')) + 1) Thank you in advance, any leads or clues are most welcome -
Django - Can't Disable CORS
I'm trying to send a post request to an API using ajax, but when I do it, the error: Access to XMLHttpRequest at 'url' from origin 'http://192.168.0.9:8000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Searching, I've found this question, and tried literally all solutions in there, but got no success. So, I started thinking that this should be a problem from the API. But I made the request with Postman Desktop and got success. I'll leave my code here: settings.py ALLOWED_HOSTS = ["*"] INSTALLED_APPS = [ "corsheaders", "administrator", "authentication", "oticket", "clients", "crispy_forms", "django.contrib.postgres", "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", ] MIDDLEWARE = [ "corsheaders.middleware.CorsMiddleware", "django.middleware.security.SecurityMiddleware", "django.contrib.sessions.middleware.SessionMiddleware", "django.middleware.common.CommonMiddleware", "django.middleware.csrf.CsrfViewMiddleware", "django.contrib.auth.middleware.AuthenticationMiddleware", "django.contrib.messages.middleware.MessageMiddleware", "django.middleware.clickjacking.XFrameOptionsMiddleware", ] CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = False Of course there are more settings, but there's no need for it. views.py [...] response = render(request, "payment/finish.html", context) response[ACCESS_CONTROL_ALLOW_ORIGIN] = ( "*" if (settings.CORS_ORIGIN_ALLOW_ALL and not settings.CORS_ALLOW_CREDENTIALS) else origin ) return response view.js $.ajax({ type: "post", url: sessionUrl, crossDomain: true, dataType: "xml", headers: { "Access-Control-Allow-Origin": "*", }, complete: (data, status) => { sessionId = $(data.responseXML).find("id").text(); }, }); -
Django 1.10 ./manage.py shell imports different than virtual env imports
Not quite sure how to word this better, however let me provide an example. I am trying to work with a library called django_nested_admin and am getting an inconsistent error. I am currently using Django 1.10 installed via pip. After reading the django-nested-admin release log, I've decided to use a compatible version of the library (3.0.21). pip install Django==1.10 pip install django-nested-admin==3.0.21 When I navigate in my browser to my admin panel, I receive the follow error: ImportError: no module named admin. A template debug traceback gives me further clues: from django.contrib.contenttypes.admin import GenericInlineModelAdmin /env/lib/python2.7/site-packages/nested_admin/nested.py Immediately, I begin to think that the version of Django I am using does not support the attribute access that is being used for import in the venv filesystem. I decide to verify this hypothesis by using the Django shell. ./manage.py shell from django.contrib.contenttypes.admin import * To my astonishment, everything imports just fine. What exactly is going on here? -
In Wagtail v2 API, how do I filter by a foreign key's string (provided by the __str__ method)
So I have a blog type of website where I'm trying to use the API to get a list of articles filtered by their topic. Here is the relevant portion of my ArticleDetailPage() class with the API field: class ArticleDetailPage(Page): """Article detail page.""" ... topic = models.ForeignKey('articles.ArticleTopic', null=True, blank=True, on_delete=models.SET_NULL) ... api_fields = [ ... APIField('topic', serializer=serializers.StringRelatedField(many=False)), ... ] And here's my ArticleTopic() class: @register_snippet class ArticleTopic(models.Model): """ Article topics that resides in Snippets. """ name = models.CharField(max_length=100) slug = AutoSlugField( populate_from='name', editable=True, max_length=100, verbose_name='slug', allow_unicode=True, help_text='A slug to identify articles by this topic.' ) panels = [ FieldPanel('name'), FieldPanel('slug') ] class Meta: verbose_name = 'Article Topic' verbose_name_plural = 'Article Topics' ordering = ['name'] # Alphabetial ordering def __str__(self): return self.name So far so good, when I take a look at the API list of posts, instead of showing the topic attribute as its ID and other data, it's represented as its string representation (i.e. a topic like space or comets). However, when I try to filter the API by appending: &topic=space to the HTML, I get an error saying: Field 'id' expected a number but got 'space'. Instead of using the StringRelatedField(many=False) serializer, I switched to APIField('topic', serializer=serializers.PrimaryKeyRelatedField(many=False, read_only=True)) … -

Django Opening Hours With UTC Support/Timezone Issue
I have a Django application where users can setup stores. I recently added functionality to support opening hours following the advice on this thread - Business Opening hours in Django. My model is almost identical to the one given except each is attached to a "Location" object. Process goes like this - these times are put in in local time by the end user, most datetimes/times being used in my application are in UTC. Originally, I thought I could figure out the timezone of each location object, then whenever I compare something to these OpeningHours, I can just use the given time and the tz (on the associated Location object) to calculate the time in UTC and then it's just a regular datetime comparison. My problem is two fold: I'm not sure this is the best solution, it already feels like I'm overthinking it a bit. The bigger problem - I'm setting the timezones on the Location objects using pytz at the time of object creation. This is to say, it will not auto update for DST or anything like that as far as I know. I could calculate the exact timezone/DST at the time of comparison every time but … -
Django: Parse HTML (containing form) to dictionary

devtools: Open response HTML in new tab
I an ajax/fetch request fails, my framework (django) does display a nice debug page, which contains a lot of useful information. In chrome devtools I can see a preview of this debug page.

But the GET does not trigger the exception which I would like to debug. -
Django API didn't detect a field in my database

Django: Unique ID's across tables
I was curious if there was a good solution to implement unique ID's between tables. class Voice(models.Model): id = .. <------| slug = ... | name = .... |-- No duplicate IDs | class Group(models.Model): | id = .. <------| slug = ... name = .... My hope is that when I get an ID in a view, selecting from one model will give me None but the other will always return the object (and vice versa). If there is a better approach feel free to share. Right now I am using the slug+id as query filters but would like to move away from that. -
(Django) Value set in session disappears after i render the request through the same view a second time
Here's what's happening: HTML Template "A" has a form that passes a variable with name="var1" to URL1. URL1 sends the request to VIEW1. VIEW1 then checks for and thereafter "gets" the "var1" variable successfully, and sets it in a session variable (request.session['variable'] = "var1" VIEW1 then renders the request to HTML Template "B", which has another form that passes a variable with name="var2" to URL1 again. URL1 sends the request to VIEW1 again. This time, "VAR1" is no longer available to "GET", but "VAR2" is. However, when i print the session variable (print(request.session['variable])), it no longer exists. My question is: Does passing a request back into the same VIEW a second time clear out any session variables you have set on the first pass? It certainly appears to be the case, but i can't figure out why. Before, I was using a global dictionary variable to store everything in, and it worked well, but it would expire if i didn't navigate quickly enough. Accordingly, i switched to storing my dictionary in the session. Thanks! -

Translation key-based internationalization with Django
Django's default i18n system uses the code language (for instance, English) as translation keys; translations into other languages must be written from that base language. For instance, in a Django template, you would write {% trans "Hello" %} and then translate "Hello" into "Bonjour" or "Hola" in the French or Spanish translation file. This has a major flaw: words that are spelled the same in English cannot be translated differently in other languages. For instance, if I use {% trans "Fire" %} in two places of my code, one of which meaning the thing that burns, and the other using a cannon, I would need "Feu" and "Tirer" respectively in French; but Django's i18n forces me to choose a single translation for "Fire". The translation keys pattern solves this: I use translation keys such as {% trans "campsite.fire" %} and {% trans "cannon.fire" %} in my code, that I translate as "Fire" in an English translation file and as "Feu" and "Tirer" respectively in the French file. Is this a supported use of Django's i18n system? How do I inject variables into such translations? -
Django: Return back from POST-redirect in Chrome without dublicate pages
I have a detail-page, with a button that submits a GET or a POST request (tried both). This request performs an action and redirects to the same detail-page (thus refreshing it). Everything seems to be fine in Firefox, but in Chrome when I press Back Button, I get back on the same page again (so redirecting to the same page creates dublicates of this page in browser history). Can I somehow change this behaviour and remove those dublicates in Chrome also? -
