How change Schemes from HTTP to HTTPS in drf_yasg?
I'm using drf_yasg for swagger documentation. When I publish my DRF app behind AWS Application Load Balancer and set listener to listen on 443 HTTPS and redirect to my EC2 on which DRF is running, swagger UI is trying to send a request to endpoint http://example.com/status rather than e.g. https://example.com/status. This creates a Google Chrome error: swagger-ui-bundle.js:71 Mixed Content: The page at 'https://example.com/swagger#/status/status_list' was loaded over HTTPS, but requested an insecure resource 'http://example.com/status'. This request has been blocked; the content must be served over HTTPS. So my solution to solve this was to explicitly set my server URL in drf_yasg.views.get_schema_view. So my code looks like: schema_view = get_schema_view( openapi.Info( title="Server Api Documentation", default_version="v1", description="", url="http://example.com/status" ) # noinspection PyUnresolvedReferences swagger_patterns = [ path("", schema_view.with_ui("swagger", cache_timeout=0), name="schema-swagger-ui"), I would like to be able not to explicitly set URL string but rather choose Schemes between HTTP or HTTPS. Is it possible in drf_yasg? -
How to create nested foreign key relations in Django Rest Framework
I have multiple foreign key relationships as defined in my Models: class Order(models.Model): total_price = models.DecimalField(decimal_places=2, max_digits=4, null=False) status = models.ForeignKey(OrderStatus, related_name='order', on_delete=models.CASCADE, null=False) customer = models.ForeignKey(Customer, related_name='order', on_delete=models.CASCADE, null=False) placed_datetime = models.DateTimeField(null=False) delivery_datetime = models.DateTimeField(null=True) class Pizza(models.Model): order = models.ForeignKey(Order, related_name='pizza', on_delete=models.CASCADE) quantity = models.IntegerField(null=False) size = models.CharField(max_length=2, null=False) price = models.DecimalField(decimal_places=2, max_digits=4, null=False) class PizzaIngredient(models.Model): pizza = models.ForeignKey(Pizza, related_name='pizzaingredient', on_delete=models.CASCADE) ingredient = models.ForeignKey(Ingredient, related_name='pizzaingredient', on_delete=models.CASCADE) class Ingredient(models.Model): display_name = models.CharField(max_length=255, null=False) code = models.CharField(max_length=10, null=False) price = models.DecimalField(decimal_places=2, max_digits=4, null=False) My POST request will look like so: { "customer":123, "pizzas":[ { "quantity":1, "size": "M", "ingredients":[ "PEPPERONI", "GROUNDBEEF", "ONION", "GREENPEP", "PINEAPPLE", "TOMATO" ] } ] } Where the array ingredients refers to the code column in Ingredients table. On a POST of an Order, I want to create a Pizza entry and the PizzaIngredient entries. Is there an easy way to do this, or am I going have to manually create them? I currently have the following for my Order view: class OrderListCreateView(generics.ListAPIView): # GET order/ # POST order/ queryset = Order.objects.all() serializer_class = OrderListSerializer def post(self, request, *args, **kwargs): try: total_price = random.uniform(5.00, 50.00) order_status = OrderStatus.objects.filter(label='Placed').first() placed_datetime = datetime.datetime.now() customer = Customer.objects.get(id=request.data['customer']) order = Order.objects.create( total_price=total_price, status=order_status, … -
How can I construct a Django model whose fields are dependent upon another model's fields
I currently am making a simple newspaper Django application, and am working on the Articles model which looks as follows: class Article(models.Model): title = models.CharField(max_length=255) body = models.TextField() #date = models.DateTimeField(auto_now_add=True) author = models.ForeignKey( get_user_model(), on_delete=models.CASCADE, ) topic = models.CharField(max_length=255) score_choices = [(-5,'-5'), (-4, '-4'), (-3,'-3'), (-2, '-2'), (-1,'-1'), (0,'0'),(1,'1'), (2,'2'), (3,'3'), (4,'4'), (5,'5')] score = models.IntegerField(choices=score_choices, default=0) I am attempting to create another model that looks something like this: class Topic(models.Model): topic_name = models.CharField(max_length=255) average_score = Within the topic model, what I would like to do is somehow query all the Articles that have topic_name as their topic, and then return a list of scores that have been entered for Articles with that topic. I'm currently pretty lost on this issue and I'm not even sure anymore if using the Django models is the best route. I've been reading through the Django Documentation as well as Third-Party books for a while but I can't find any reference here. To summarize, I have two models: Article and Topic. Article has a field called 'topic' as well and I would like to create a field for my Topic class that is a function of the score field for all Article objects … -
Javascript modal to crop existing images ? how ti iterate through list of modals to handle them?
I have a page that has multiple images uploaded by user and user could select a part of these images to submit in a form ( just the coordinates x,y,h,w ) so I made a modal for every image but my problem is with the javascript function as it doesn't trigger the modal to show and I'm not really familiar with javascript yet. I use cropper.js to grab the cropping data and it loaded successfully when I tried it on a regular file upload form where there was one form in the page and the modal was triggered by the file field but now I want to use it with already existing image. the images list: <div class="row"> {% for image in Patient_detail.images.all %} <div class="col-md-4 img-box"> <div class="card mb-4 shadow-sm"> <a href="{{ image.pre_analysed.url }}" data-lightbox="patient's images" > <img src="{{ image.pre_analysed.url }}" class="img-thumbnail" id="img{{image.pk}}" > </a> <div class="card-body"> <div class="d-flex justify-content-between align-items-center"> <div class="btn-group"> {% endif %} <form method="POST" enctype="multipart/form-data" action="{%url 'patients:image_crop' pk=image.pk %}" id="formUpload{{image.pk}}"> <input type="hidden" name="x" id="id_x{{image.pk}}"> <input type="hidden" name="y" id="id_y{{image.pk}"> <input type="hidden" name="width" id="id_width{{image.pk}"> <input type="hidden" name="height" id="id_height{{image.pk}"> </form> <button type ="button" class="btn btn-sm btn-outline-defaul" id="crop{{image.pk}}">Crop</button> </div> </div> </div> </div> </div> {% endfor %} </div> and the … -

Autocomplete Address Fill in Django CreateView

How to blacklist a JWT token with Simple JWT (django rest)?
I'm using Simple JWT to use JWT tokens in my Django rest API. It works great but I would like to be able to blacklist a token when a user logs out. In the documentation, it is said: If the blacklist app is detected in INSTALLED_APPS, Simple JWT will add any generated refresh or sliding tokens to a list of outstanding tokens. It will also check that any refresh or sliding token does not appear in a blacklist of tokens before it considers it as valid. The Simple JWT blacklist app implements its outstanding and blacklisted token lists using two models: OutstandingToken and BlacklistedToken. Model admins are defined for both of these models. To add a token to the blacklist, find its corresponding OutstandingToken record in the admin and use the admin again to create a BlacklistedToken record that points to the OutstandingToken record. However, I didn't find any code example and I'm not sure how this should be implemented. An example would be greatly appreciated. -
