How to set lookup_field of GenericViewSet with JSONfield key?
How do I set the lookup_field with a key in JSONField model? The model: exchange = models.ForeignKey(StockExchange, on_delete=models.CASCADE, related_name='tickers') fundamentals = models.JSONField(null=True, blank=True) The viewset: class StockCardsV2ViewSet(BaseGetViewSet): search_fields = ('^fundamentals__General__Name', '^fundamentals__General__Code') filter_backends = (filters.SearchFilter,) queryset = Ticker.objects.all() serializer_class = StockCardsV2Serializer lookup_value_regex = '[0-9a-zA-Z_.]+' lookup_field = 'fundamentals__General__Code' The Serializer: class Meta: model = Ticker fields = ('id', 'url', 'name', 'ticker', 'logo_url', 'currency_symbol', 'sector', 'industry', 'esg_rating', 'weekly_prices', 'monthly_prices', 'yearly_prices', 'two_yearly_prices', 'ad', 'in_watchlist') lookup_field = 'fundamentals__General__Code' extra_kwargs = { 'url': {'lookup_field': 'fundamentals__General__Code'}, } There are no problems with search_fields but I get this error for the lookup_field.

DRF - Upload a valid image
Hope someone would be able to help me out here. I am trying to update an image on a table called MyCards, when updating this image the system should then look to see if this image contains certain word, if so then the field points would be increased by one. But, when trying to update the image I get the following error { "image": [ "Upload a valid image.

DRF: Overwrite inculded default endpoints to custom views
So I am using dj-rest-auth with Simple-JWT. My urls.py is: urlpatterns = [ path('dj-rest-auth/', include('dj_rest_auth.urls')), ] But I want to update a specific endpoint of dj-rest-auth.urls to a custom view: path('dj-rest-auth/login/', views.MyTokenObtainPairView.as_view(), name='token_obtain_pair') Simply adding both the lines together ain't doing the job. dj-rest-auth/login/ gives the default view only. How shall I overwrite it? -
Django lookup by JSONField array value
Let's say I have MySQL database records with this structure { "id": 44207, "actors": [ { "id": "9c88bd9c-f41b-59fa-bfb6-427b1755ea64", "name": "APT41", "scope": "confirmed" }, { "id": "6f82bd9c-f31b-59fa-bf26-427b1355ea64", "name": "APT67", "scope": "confirmed" } ], }, { "id": 44208, "actors": [ { "id": "427b1355ea64-bfb6-59fa-bfb6-427b1755ea64", "name": "APT21", "scope": "confirmed" }, { "id": "9c88bd9c-f31b-59fa-bf26-427b1355ea64", "name": "APT22", "scope": "confirmed" } ], }, ... Any way I can filter all of the objects who's actors name contains '67', for example? Closest variant I have is that I got it working like that: queryset.filter(actors__contains=[{"name":"APT67"}]) But this query matches by exact actor.name value, while I want to to accept 'contains' operator. I also have it working by quering with strict array index, like this: queryset.filter(actors__0__name__icontains='67') But it only matches if first element in array matches my request. And I need that object shall be returned in any of his actors matches my query, so I was expecting something like queryset.filter(actors__name__icontains='67') to work, but it's not working :( So far I have to use models.Q and multiple ORs to support my needs, like this - search_query = models.Q(actors__0__name__icontains='67') | models.Q(actors__1__name__icontains='67') | models.Q(actors__2__name__icontains='67') | models.Q(actors__3__name__icontains='67') queryset.filter(search_query) but this looks horrible and supports only 4 elements lookup(or I have to include more … -

Django- Template not found
I can't seem to get my delete, edit and add review functionality working. The errors come as soon as I try to navigate to the urls I have set up. When I try and add a new review using my link on the reviews page I get the below message: TemplateDoesNotExist at /reviews/add I don't understand why because I have linked the url above to the template, which I have created. The issue I have with my edit/delete views is that the url it searches for when I click the button is just /edit/ or /delete/ rather than reviews/edit/int:pk or reviews/delete/int:pk as per my urls. I have pasted my code below, any help would be much appreciated!

Problem of signature with webauthn on django with djoser
I'm working at the moment on an implementation of webauthn on a project. The main point is to give the possibility to user to use FaceId or fingerprint scan on their mobile on the website. I tried the djoser version of webauthn but I wanted to give the possibility to user that already have an account so I took the implementation of webauthn of djoser and I updated it to make it working with already created account. I can ask for the signup request of a webauthn token and create the webauthn token with the front (Angular) where I use @simplewebauthn/browser ("@simplewebauthn/browser": "^6.3.0-alpha.1") . Everything is working fine there. I use the latest version of djoser by pulling git and the version of webauthn is 0.4.7 linked to djoser. djoser @git+https://github.com/sunscrapers/djoser.git@abdf622f95dfa2c6278c4bd6d50dfe69559d90c0 webauthn==0.4.7 But when I send back to the backend the result of the registration, I have an error: Authentication rejected.

Products are not displayed when simple search on django
I do search on Django and faced with a problem: products are not displayed. I dont understand why views class SearchView(ListView): template_name = 'store/products.html' def get_queryset(self): query = self.request.GET.get('search', '') if query: products = Product.objects.filter(Q(name__icontains=query) | Q(description__icontains=query)) else: products = Product.objects.all() return products search template <form class="form-inline mb-3" action="{% url 'search' %}" method="get"> <div class="form-group col-8 col-md-10 pl-0"> <input class="form-control w-100" type="search" placeholder="Поиск по сайту" name="search"> </div> <div class="form-group col-4 col-md-2 pl-0"> <button class="btn btn-info" type="submit">Найти</button> </div> </form> products template {% extends 'base.html' %} {% block title %} List {% endblock %} {% block content %} <body style="background-color: whitesmoke;"> {% for product in products %} <main class="container mt-3" style="text-align: center; max-width: 500px;"> <div style="border: 5px solid white; background-color: white;"> <a href="{% url 'product_detail' product.id %}"> <img src="{{ product.image.url }}" style="width:15vh; height:auto;"><br> </a> <p style="font-size: 20px">{{ product.name }}</p> <p style="font-size: 22px">{{ product.price }} руб.</p> <form method="post" action="{% url 'cart_add' product.id %}"><br> <p style="display: none"></p> {{ form }} {% csrf_token %} {% if request.user.is_authenticated %} <input type="submit" value="Add to cart"> {% else %} <p></p> {% endif %} </form> </div> </div> </div> </main> {% endfor %} </body> {% endblock %} I did the same search and all good.

create Model objects inside another models's Adminview
I'm trying to generalize access permissions to certain Nodes for each of my Groups. I have an Access Model model with three different fields: access_type, group and node. Each group can have either Source, Destination or Bidirectional Access to a node which has a name: class Access(models.Model): class AccessType(models.TextChoices): BIDIRECTIONAL = "bi", "Bidirectional" SOURCE = "src", "Source" DESTINATION = "dst", "Destination" access_type = models.CharField(max_length=3, choices=AccessType.choices) group = models.ForeignKey(Group,on_delete=models.CASCADE, related_name='GroupAccess') node = models.ForeignKey(DicomNode, on_delete=models.CASCADE) name = models.CharField(unique=True, max_length=128, null = True) Similar to the common permission view inside the adminView I'd like to create Access objects inside the GroupView, so that they are created with the group which I am inside at the moment. Also, I'd like them do be displayed on the left side with all available Accesstypes and nodes, seperated with an '|' just like all the available permissions: enter image description here I have done the same already with a form to add existing users to a group: class GroupForm(forms.ModelForm): users = forms.ModelMultipleChoiceField( label='Users', queryset=User.objects.all(), required=False, widget=admin.widgets.FilteredSelectMultiple( "users", is_stacked=False)) class Meta: model = Group exclude = () # since Django 1.8 this is needed widgets = { 'permissions': admin.widgets.FilteredSelectMultiple( "permissions", is_stacked=False), } class MyGroupAdmin(GroupAdmin): form = GroupForm list_display … -
