How to implement autocomplete user search in React and Django Rest Framework
So basically I'd like to implement a user search system in react which would send an api request to my django backend which would send back the results. This is an easy implementation if I wanted the results once I hit search but I want the results displayed as autocompletes. For example in Twitter it autocompletes what you are searching for. How would I implement this. I am using axios for my requests if that helps. A side note would be that I'd like to wait maybe a second or 2 before sending the request because I would want to send to many requests and slow down the server. Thank you! -
Display User's 'is_active' status in TabularInline Django
I have a Client object that has a User and a Company objects as FKs class Client(models.Model): user = models.OneToOneField(User) company = models.ForeignKey(Company, blank=True, null=True) In my CompanyAdmin, I want a list of all clients as a TabularInline, including the active status of each client (based on user object) class CompanyClients(admin.TabularInline): model = Client fields = ('user', 'master') class CompanyAdmin(admin.ModelAdmin): inlines = [CompanyClients] I want to add a column in my TabularInline to indicate that that user is active or not. I tried using 'user__is_active' to my fields but I get this error: Unknown field(s) (user__is_active) specified for Client I just want an indication even if read-only (which I tried by putting a readonly_fields and it didn't work too), not looking to save/edit each client user's active status value from the Tabular form. How can I approach this? Thanks in advance. -
User avatar not displayed in Django

So I created the model and the form. Image is not displaying on the page. But form saves the image to folder. Where is mistake? request.user.avatar.url doesn't work. Maybe the image is not attached to User? Thanks for the help P.S. djagno-avatar is not good for me. -
autocomplete in django-admin site for every foreign-key field
What could be the way to make every foreign-key field searchable/autocomplete in django-admin site in general? Means whenever I define a foreign-key field in model, i would need nothing more to make it autocomplete. I could not find any such module because the module like https://django-autocomplete-light.readthedocs.io/en/master/gfk.html facilitate with even complicated way, and do not provide a thing like odoo where developer would not need to code for each field to make it autocomplete I have using odoo, where I define a field in any child_model1 like parent_id = fields.Many2one('my_module.parent_model1') I simply get a searchable and autocomplete select list in my child_model1's form, I have nothing to add more anywhere. But in contrast with django when i define a filed on child_model1 like parent_id = models.ForeignKey(ParentModel1) First i would need to define on_delete=?, even I have no option to set anywhere globally that hello django please always restrict on delete until I tell you to make a field on_delete=cascade Then I need that all of my foreign-key fields in any model need to be autocomplete but I always have to write each field in each each child model's admin like autocomplete_fields = ['parent_id'] also I have to give something like search_fields … -
How to use Cross Site Request Forgery protection correctly?
I've only started getting into web programming with Django recently. In order to make my website more secure, I used csrf_token when sending POST request, followed what I saw in https://docs.djangoproject.com/en/3.1/ref/csrf/. However, as I included <script src="https://cdn.jsdelivr.net/npm/js-cookie@rc/dist/js.cookie.min.js"></script> in my HTTP file from Javascrip Cookie Library, I can get the csrf_token directly from my browser in Inpsect>console. I am not sure if I did this correctly or not, please give me some pointers. -

Delete method is not allowed when calling api endpoint in Django Rest Framework using DestroyModelMixin
I have imported DestroyModelMixin in UpdateAPIView so that I can use both PUT and DELETE methods in the same api endpoint. It works for PUT and can be updated, but when I call DELETE in postman, it says DELETE is not allowed. But, when I make a separate view using just DestroyAPIView, it works fine. I want to have a single api for both update and delete. My models: class CartItem(models.Model): cart = models.ForeignKey(Cart,on_delete=models.CASCADE, related_name='cartitems') item = models.ForeignKey(Product,on_delete=models.CASCADE) quantity = models.IntegerField() def __str__(self): return self.item.name My view: class CartItemUpdateAPIView(UpdateAPIView,mixins.DestroyModelMixin): permission_classes = [IsAuthenticated] queryset = CartItem.objects.all() serializer_class = CartItemSerializer def perform_update(self, serializer): serializer.save() def perform_destroy(self, instance): instance.delete() My serializer: class CartItemSerializer(serializers.ModelSerializer): class Meta: model = CartItem fields = ['id','cart', 'item', 'quantity'] depth = 1 My urls: path('api/cartitemupdate/<int:pk>', views.CartItemUpdateAPIView.as_view(), name='api-cartitem-update'), -

Can I create a model Class in django dynamically?
So I have a tools/model.py Where I add all the tools that I will be using. The thing is each tool has to be a table its self so I can create more than one tool of each and to link that tool to the project that it is being used in. I am using MYSQL database For example: Tools Table must have: tools_ID tools_name tools_quantity now according to the tools_name I want to create a model or a table for it. For example: If I added ScrewDrivers to the Tools table I want it to create a ScrewDrivers Table automatically, Where all the child tables that inherit from Tools tables has the same structure and can't add ScrewDrivers more than the quantity that is specified in the Tools table. ScrewDrivers table: Rows = Quantity in Tools table ID ScrewDrivers_name ScrewDrivers_status (Available or being used in a project) -

Declare dynamic variable in django template
I'm currently passing via the context a variable named image_1, image_2, etc. I'm unsure how many images there. So I'm trying to make a for loop to go through the total count and make variables, {{ image_1 }}, {{ image_2 }}, etc. But the only thing I can think to try is this, and it's not working. {% for i in 10 %} {{ image}}{{ i }} {% endfor %} Of course the 10 being another variable I am passing. So in summary I'm trying to make {{ image}}{{ i }} instead be the equivalent of {{ image_1 }} via the for loop. -

How can I fix my PATCH request to append to ArrayField, rather than delete and replace the whole object?
I have a problem with my PATCH request instance. Currently, data that is being PATCHED and sent from a request is overriding every item in my list of strings ArrayField inside my model object. I need my patch request behavior to append to the rest of the items in ArrayField object, not delete/override. How can I go about doing that? I assume I need to override the patch method within RetrieveUpdateAPIView, so I've started out here: def patch(self, request, **kwargs): item = self.kwargs.get('slug') serializer = StockListSerializer(item, data=request.data, partial=True) if serializer.is_valid(): serializer.save() Response(serializer, status=status.HTTP_200_OK) return Response(status=status.HTTP_400_BAD_REQUEST) serializer.py: class StringArrayField(serializers.ListField): def to_representation(self, obj): obj = super().to_representation(obj) return ",".join([str(element) for element in obj]) def to_internal_value(self, data): data = data.split(",") return super().to_internal_value(data) class StockListSerializer(serializers.ModelSerializer): stock_list = StringArrayField() class Meta: model = Bucket fields = ("stock_list",) view.py class EditBucketSymbols(generics.RetrieveUpdateAPIView): permission_classes = [IsAuthenticated] serializer_class = StockListSerializer queryset = Bucket.objects.all() def get_object(self, queryset=queryset, **kwargs): item = self.kwargs.get('slug') return get_object_or_404(Bucket, slug=item) url.py: path('bucket/symbols/<str:slug>/', EditBucketSymbols.as_view(), name='editsymbols') model.py: stock_list = ArrayField(models.CharField(max_length=6,null=True),size=30,null=True, blank=True) -
