Can't load static image in django when using a loop
I cant get an image to load in django when i use a for loop, the image will load if i specify the path for each file. Works: when I try to use a loop it won't load the images. view.py: operators = [] directory = os.path.join(os.path.join(os.path.join(os.path.join(settings.BASE_DIR) ,'static'),'images'),'operators') for file in os.listdir(directory): if file.endswith(".png") or file.endswith(".jpg"): operators.append(file) then i try to return image using context. html file: {% if operators %} There are {{ operators|length }} records: {% for operator in operators %} <div class="media"> <img src="{{operator}}" class="align-self-center mr-3" alt="..."> </div> {{operator}} {% endfor %} {% else %} There are no records in the system {% endif %} It would be amazing if someone had an idea on how to fix my code. settings.py: STATIC_URL = '/static/' # Pointing django to the static file location. STATICFILES_DIRS = ( os.path.join(BASE_DIR,'static'), ) -
Is there a way to add an aggregated field to an annotated Queryset
I have a queryset with two objects in it like below: fake = queryset({'id':1, 'price': 10, 'relation_field_id':5}, {'id':1, 'price': 15, 'relation_field_id':5}) All relation_field_ids have number 5. I want to have a Queryset or Dic that aggregated with sum of the price field and just one of the relation_field_id in it like: queryset({'total_price': 25, 'relation_field_id':5 }) I would be glad anyone answer to this question. Thank you. -

Any tip? Thanks -
How do I universally connect to Redis both in Docker and PyTest?
One of the Django views in code I test connects to Redis using a redis.Redis class. red = redis.Redis(host='redis-map', port=6379) Obviously, this method isn't good when testing because it uses the same DB as when opening it outside of testing. I found a library called pytest-redis and replaced all the redis.Redis constructors with calling a function I created: import sys, redis from pytest_redis import factories def create_redis(): if not 'pytest' in sys.modules: return redis.Redis(host='redis-map', port=6379) else: return factories.redisdb('redis_proc')() However, when I run the test, it returns this error: web_1 | Failed: Fixture "redisdb_factory" called directly. Fixtures are not meant to be called directly, web_1 | but are created automatically when test functions request them as parameters. web_1 | See https://docs.pytest.org/en/latest/fixture.html for more information about fixtures, and web_1 | https://docs.pytest.org/en/latest/deprecations.html#calling-fixtures-directly about how to update your code. I don't want to rewrite what is pretty much all of my code - lots of code in my WebSocket consumer in Django Channels also uses Redis. What should I do? -
How dynamically define and create custom "through" model with specific fields and structure for all custom manytomanyfield
I have a model with a lot of m2m fields: class Model1(models.Model): useful_data = models.TextField(null=True) class Model2(models.Model): useful_data = models.TextField(null=True) class Entity(models.Model): field1 = CustomManyToManyField('entities.Model1') field2 = CustomManyToManyField('entities.Model2') field3 = CustomManyToManyField('entities.Model2') ... I want dynamically created model "through" for all CustomManyToManyField with specific fields. So for every CustomManyToManyField I need to dynamically create new model with this structure. For example for field1 field this model will be created: class CustomThroughModel(models.Model): entity = models.ForeignKey('entities.Organization') model1 = models.ForeignKey('entities.Model1') data_source = models.CharField() updated_at = models.DateTimeField(auto_now=True) deleted_at = models.DateTimeField(null=True) created_at = models.DateTimeField(auto_now_add=True) I don't want to copy paste similar models for every manytomanyfields -
How to convert this category_detail function-based view to a CBV (DetailView)
I have this function-based view doing what I need it to do - get the list of all Posts filed under s specific Category and reach that list by going to example.com/economics/ (where economics is the slug od that specific Category). There I would find the list of all my posts filed under Economics category and create links so I can click on them and go to a single post page. Currently, my FBV looks like this: def category_detail(request, category_detail_slug=None): categories = Category.objects.all() #Show only published posts posts = Post.objects.filter(status__exact='1') if category_detail_slug: category = get_object_or_404(Category, slug=category_detail_slug) posts = posts.filter(category=category) return render(request, 'blog/category/single.html', {'category_detail_slug': category_detail_slug, 'category': category, 'categories': categories, 'posts': posts}) I started creating my CBV like this: class CategoryDetailView(DetailView): model = Category template_name = 'blog/category/single.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) return context I know I need to pass some context, but somehow this keeps failing me. My URL for this is defined as such: path('<slug:category_detail_slug>/', views.CategoryDetailView.as_view(), name="single_category") -

Django pre_save or post_svae is not triggered on through model but post_delete is
So I am working on a google calendar integration. I have users and shifts and in the through model I want to add a google_calendar_id. So right now I have a through model class ShiftUser(models.Model): shift = models.ForeignKey("shift.Shift", models.DO_NOTHING, related_name="shift_users") user = models.ForeignKey(User, models.DO_NOTHING, related_name="user_shifts") google_calendar_id = models.CharField(max_length=1024, null=True) class Meta: unique_together = (("shift", "user"),) But the save method does not work on through model so I added a pre_save on the model: @receiver(pre_save, sender=ShiftUser) def shift_user_change(instance, **kwargs): GoogleIntegration.create_event(instance) I tried this approach with pre_save and post_save but both are not triggered. But when I use post_delete it does work. Does anybody know why this is? For the record. I tried m2m_changed but I need to know which users changed and from what I gathered I can't do that without doing two queries per change in the relationship. This is of course not the worst but I think the pre_save is a cleaner solution. -

Override generics.RetrieveAPIView called with slug field
I'm using generics.RetrieveAPIView in DRF to return details using a slug lookup field. I get the slug from the url www.../slug, and then fetch the required data from the API: http://...api/slug/. It works fine when the user enters the 'slug' in the url however when they login, they don't enter the slug so I set it with code. In my code, I set the slug to anonymous. At this points, I use the User in request to fetch the details but it's not working. Please help. Here's my generics view: class StoreDetail(generics.RetrieveAPIView): lookup_field = 'slug' serializer_class = StoreSerializer def get_queryset(self): if self.kwargs: slug = self.kwargs['slug'] if slug != 'anonymous': # means slug is in URL return Store.objects.filter(slug=slug) else: # manually get slug from db id = self.request.user.id store = Store.objects.get(account=id) slug = store.slug # Everything up to here works however it returns 404(Not found) return Store.objects.filter(slug=slug) -
Updating User and extended User Profile in one API Call in Django Rest Framework
I have a form on my frontend where the user can update some info - part of the fields are supposed to update the default Django User Model, while others should update the User Profile model, which has a One-To-One Relationship to the User. I am running the code below but get the following error: AttributeError: 'str' object has no attribute '_meta' api.py # Get and Update User API class UserAPI(generics.RetrieveUpdateAPIView): permission_classes = (permissions.IsAuthenticated,) serializer_class = UserSerializer def retrieve(self, request, *args, **kwargs): serializer = self.serializer_class(request.user) return Response(serializer.data) def update(self, request, *args, **kwargs): user_data = request.data['user'] profile_data = request.data['profile'] user_serializer = self.serializer_class(request.user, data=user_data, partial=True) user_serializer.is_valid(raise_exception=True) user_serializer.save() if profile_data: profile_serializer_class = ProfileSerializer profile_serializer = ProfileSerializer(request.user.username, data=profile_data, partial=True) print(profile_serializer) profile_serializer.is_valid(raise_exception=True) profile_serializer.save() response = {'user': user_serializer.data, 'profile': profile_serializer.data} return Response(response) # UserProfile API class ProfileAPI(generics.RetrieveAPIView): lookup_field = 'user' serializer_class = ProfileSerializer queryset = Profile.objects.all() serializers.py # User Serializer class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'username', 'email', 'first_name', 'last_name') # Profile Serializer class ProfileSerializer(serializers.ModelSerializer): user = serializers.SlugRelatedField(read_only=True, slug_field="username") class Meta: model = Profile fields = '__all__' I am making a patch request in the following format: { "user": { "username": "testuser" }, "profile": { "bio": "hello this is my bio" } … -
Form attributes not displaying on webpage
I am trying to add classes to my forms but the classes are not being applied. I cannot find what I'm doing wrong. Any help would be greatly appreciated. I'm hoping to set bootstrap classes, so I'd like , if possible. class PersonalInformation(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=200, default='') surname = models.CharField(max_length=200, default='') dob = models.DateTimeField('Date of birth (mm/dd/yyyy)', null=True, default=now) preferred_subjects = models.CharField('Are there subjects you would prefer doing?', max_length=200, default='') class PersonalInformationForm(forms.ModelForm): OPTIONS = ( ("ANI", "Animals"), ("ART", "Art"), ("COM", "Communication"), ) preferred_subjects = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple( attrs={ 'class' : 'not working', 'id' : 'not working' } ), choices=OPTIONS) class Meta: model = PersonalInformation fields = ['first_name', 'surname', 'dob', 'preferred_subjects'] widgets = { 'dob': DatePickerInput( options={ "format": "MM/DD/YYYY", "showClose": False, "showClear": False, "showTodayButton": False, } ), } Thank you. -
