Django Traverse Foreign Keys
I have 3 models and I am trying to create a dashboard with a list of Trials that spans all Client Sessions for a specific client chosen via a filter. Here are the models: class Trial(models.Model): behavior_name = models.ForeignKey(Behavior, on_delete=models.CASCADE) client_session = models.ForeignKey(Client_Session, on_delete=models.CASCADE) frequency_input = models.PositiveIntegerField(default=0, blank=True) duration_input = models.DurationField(blank=True, default=timedelta(minutes=0)) class Meta: verbose_name_plural = 'trials' def __str__(self): return str(self.id) class Client_Session(models.Model): name = models.CharField(max_length=200, null=False) session_date = models.DateField(blank=False,null=False) client = models.ForeignKey(Client, on_delete=models.CASCADE) behaviors = models.ManyToManyField(Behavior, null=False) therapist = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) class Meta: verbose_name_plural = 'clientsessions' def __str__(self): return self.name class Client(models.Model): #user = models.ForeignKey(User, on_delete=models.CASCADE) first_name = models.CharField(max_length=200) last_name = models.CharField(max_length=200) date_of_birth = models.DateField(blank=True, null=True) gender = models.CharField(max_length=10, choices=GENDER_CHOICES,blank=True) gaurdian_first_name = models.CharField(max_length=200, blank=True) gaurdian_last_name = models.CharField(max_length=200, blank=True) diagnosis = models.CharField(max_length=200, choices=DIAGNOSIS_CHOICES, blank=True) therapist = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) def __str__(self): return self.last_name Here is the view that im trying to create def dashboard(request): # filter list of client sessions by selected client client_sessions = Client_Session.objects.filter(therapist=request.user) client = DashboardClientFilter(request.GET, queryset=client_sessions) client_sessions = client.qs #Create list of Trials across Client Sessions for the filtered client trial_list = Trial.objects.filter(client_session__client=client) -
method to test get_queryset using Pytest
I've created a get_queryset function in order to fetch multiple product Id's filter_fields = ( "id", "name", "mass", ) ordering_fields = ( "id", "name", "mass", ) def get_queryset(self): queryset = Product.objects.all() id_value = self.request.query_params.get('id') if id_value is not None: queryset = queryset.filter(id__in = id_value) return queryset I would like to test this in test.py using pytest to check if the code is actually working with multiple id's. I am not very fond of django testing so how could I test this code out by creating a def test function in test.py The current approach to test function is def test(self, client, authenticated_headers): request = RequestFactory().get('/views/ProductsView') view = ProductsView view.request = request input_data = [ { "id": "1" * 100, "name": "Test Product1111111", "mass": 100, }, { "id": "1" * 100, "name": "Test Product1111111", "mass": 100, }, ] qs = view.get_queryset() res = client.post( reverse("______"), data=input_data, **authenticated_headers, ) self.assertQuerysetEqual(qs, Product.objects.all()) assert res.status_code == 200 -
Two querysets in one view in Django

Django PermissionError: [WinError 32] The process cannot access the file because it is being used by another process

Extending multiple CustomViewsets - as readonly with Django
in our project, our lead developer assigned a task to refactor some viewsets in our project. Create a readonly Asset view that will return all defaults and romy assets So the original code looks like this class DefaultAssetViewSet(viewsets.ModelViewSet): queryset = DefaultAsset.objects.all() serializer_class = DefaultAssetSerializer permission_classes = [IsAdminUser] filter_backends = [DjangoFilterBackend, OrderingFilter, SearchFilter] filterset_fields = ['name'] search_fields = ['name', 'default_value'] @action(detail=False, methods=['get']) def defaults(self, request): defaults = {} for d in self.queryset.all(): defaults[d.name] = d.default_value return Response({'defaults': defaults}) def destroy(self, request, *args, **kwargs): try: return super().destroy(request, *args, **kwargs) except models.ProtectedError: return Response( {'detail': ErrorDetail('Unable to perform this action.')}, status=status.HTTP_403_FORBIDDEN) class RomyAssetViewSet(viewsets.ModelViewSet): queryset = RomyAsset.objects.all() serializer_class = RomyAssetSerializer permission_classes = [IsAdminUser] filter_backends = [DjangoFilterBackend, OrderingFilter, SearchFilter] filterset_fields = [ 'romy', 'default_asset' ] search_fields = [ 'romy', 'default_asset' ] So my first idea to come to my mind is to extend these two Views into AssetViewSet class class AssetViewSet(RomyAssetViewSet, DefaultAssetViewSet,viewsets.ReadOnlyModelViewSet): """ some code here""" Is it possible to extend custom viewsets like these? And also how to implement get or list for both RomyAssetViewet and DefaultAssetViewset inside AssetViewsetClass? -

Heroku Posgres' DATABASE_URL cannot be loaded in Django's setting.py and application error occurs
When building an API server using Django+REST framework and uploading it to Heroku, hard-coding Heroku Postgres' DATABASE_URL in the DATABASES of setting.py as follows will work on Heroku without problems. (xxx is originally the information of DATABASE_URL, but we dare to hide it this time) DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'xxx', 'HOST': 'xxx', 'PORT': '5432', 'USER': 'xxx', 'PASSWORD': 'xxx, } } However, you can add a .env file to your Django project, stating the following (where xxx is the information originally entered for the DATABASE_URL, but we've dared to hide it this time) DATABASE_URL=postgres://xxxx In setting.py import dj_database_url from dotenv import ( find_dotenv, load_dotenv, ) load_dotenv(find_dotenv()) DATABASES = { 'default': dj_database_url.config(conn_max_age=600), } If I put something like this, it works in the local environment, but when I upload it to heroku, I get an application error. Do you know the cause? -
Don't know how to query a complex SQL in django
I have these two models below class Category(models.Model): id = models.AutoField(primary_key=True) cate_id = models.CharField(max_length=16, editable=False, default=utils.generate_random_str) name = models.CharField(max_length=64, default="") class Record(models.Model): id = models.AutoField(primary_key=True) record_id = models.CharField(max_length=16, editable=False, default=utils.generate_random_str) count = models.IntegerField(blank=True) user = models.ForeignKey(Profile, on_delete=models.CASCADE, null=True) And I want to make SQL Query distinct cate_id and Sum their values and Group them like this: SELECT B.name , SUM(A.count) AS count_sum FROM app_record AS A, app_category AS B WHERE A.`user_id` = 1 AND B.cate_id IN ( SELECT DISTINCT(B.cate_id) FROM app_record AS C, app_category AS D WHERE C.category_id = D.id ) AND A.category_id = B.id GROUP BY B.cate_id; I expect the results should be like this: +---------+-----------+ | name | count_sum | +---------+-----------+ | Test1 | 494 | | Test2 | 18 | | Test3 | 269 | +---------+-----------+ 3 rows in set (0.001 sec) I want to make that query in Django but I couldn't work out on my own. I have tried this but it didn't seem to work out: Record.objects.filter( user=user ).distinct().annotate( record__category_id=F('category__id') ).aggregate( count_sum=Sum('count') ) I don't know how to do that, hope someone can solve this.Thanks a lot. -
How to write an ajax like button for django like object that uses foreign key?
So I have been trying to write a jquery ajax button that would stop page reload effect when a post object is liked, As I'm having a challenge doing so because my like model object is using a foreign key on my webapp, As I can do this with a many to many field but my challenge is when I change my like button to a ManyToMany field i wouldn't be able to recover already liked post on my app and I find it would be much convenient if I could write jQuery ajax to handle the foreign key like object instead. This is what i have been able to come up with , but it doesn't trigger the like button ! #Model for like class Like(models.Model): user_like = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='user_likes', on_delete=models.CASCADE) product = models.ForeignKey(Product, related_name='user_likes', on_delete=models.CASCADE) like_date = models.DateTimeField(auto_now=True) View.py def like_button(request, pk, c_slug=None): user = request.user if request.method =="POST": if request.POST.get("operation") == "like_submit" and is_ajax(request=request): content_id=request.POST.get("content_id",None) content=get_object_or_404(Like,pk=content_id) if liked.likes.filter(id=request.user.id): #already liked the content content.likes.remove(request.user) #remove user from likes liked=False else: content.likes.add(request.user) liked=True resp = { 'liked':liked,'like_id':content_id, } response = json.dumps(resp) return HttpResponse(response,content_type = "application/json") product = Product.objects.get(pk=pk, slug=c_slug) liked= False like = Like.objects.filter(user_like=user, product=product) if like: like.delete() else: … -

Problem with .only() method, passing to Pagination / Serialization --- all fields are getting returned instead of the ones specified in only()
I am trying load some data into datatables. I am trying to specify columns in the model.objects query by using .only() --- at first glance at the resulting QuerySet, it does in fact look like the mySQL query is only asking for those columns. However, When I try to pass the QuerySet into Paginator, and/or a Serializer, the result has ALL columns in it. I cannot use .values_list() because that does not return the nested objects that I need to have serialized as part of my specific column ask. I am not sure what is happening to my .only() db_result_object = model.objects.prefetch_related().filter(qs).order_by(asc+sort_by).only(*columns_to_return) paginated_results = Paginator(db_result_object,results_per_page) serialized_results = serializer(paginated_results.object_list,many=True) paginated_results.object_list = serialized_results.data return paginated_results -

Stripe Checkout with django-stripe: how pass fees on to customers (surcharging)?
I am using django-stripe to generate Stripe Checkouts. I would like to pass the Stripe fees on to my customers ("surcharging"). I found a help article from stripe regarding this. It says in general how to calculate the fees to put on top of the price of the product. The problem is, that different payment methods have different fees. And when creating the Checkout, I must calculate the final price (including the fees I want to pass on) before I know what payment method the customer will select (and therefore what fees the customer will have to pay). So I don't know the fees when I must put them on top of the price the user has to pay in the Checkout. Is there a way out of this dilemma? -

Django - compare values of keys in dictionaries in two different lists
I have two lists of dictionaries that I have pulled from an XML file using elementtree. Each list of dictionaries contains dozens of keys/values but for simplicity sake let's say it's similar to the below: list1 = [{'id': '100', 'first_name': 'john'}, {'id': '101', 'first_name': 'joe'}] list2 = [{'id': '100', 'last_name': 'doe'}, {'id': '101', 'last_name': 'bloggs'}] I'm using Django to build a table with the data and want to put the first names (from list1) and last names (from list2) on the same row of the table where there's a match in the 'id' values, but I can't figure out how to do this. If I wanted to list them in python I would use: for v in list1: print(v['id']) print(v['first_name']) for i in list2: if i['id'] == v['id']: print(i['last_name']) But I can't figure out how to write this with django tags in the HTML template. Here's what I've tried (and variations thereof): {% for v in list1 %} <tr> <td>{{v.id}}</td> <td>{{v.first_name}}</td> {% for i in list2 %} {% if {{v.id}} == {{i.id}} %} <td>{{i.last_name}}</td> {% endif %} {% endfor %} </tr> {% endfor %} -
Django notification hq mark_as_read
I am using django-notifications-hq for make notifications working on a Django app. I am having problems with the function "mark_as_read". What I am trying to achieve is to have a notification list and, when clicking on a notification, mark it as read and redirect to the url of the post. The problem is that, basically, I am having problems with that. I tried many different ways on the template such as: <a href="{% url 'main:question_details' pk=notification.target.question.id slug=notification.target.question.slug %}?next={{notification.mark_as_read}}" class="text-reset notification-item"> {% if notification.unread == True %} <div class="d-flex alert-warning"> {% else %} <div class="d-flex"> {% endif %} <div class="flex-1"> <span class="text-dark small">Commento</span> <span class="text-dark small float-end"><i class="mdi mdi-clock-outline"></i> {{notification.timestamp|naturaltime}}</span> <h6 class="mb-1">{{notification.verb}}</h6> <div class="font-size-12 text-muted"> <p class="mb-1">{{ notification.target.comment }}</p> </div> </div> </div> </a> In this case the redirect works but, as soon as I press the dropdown menu, the notification is already marked as read. If I remove the ?next={{notification.mark_as_read}} the redirect works but the notification isn't marked as read. Anyone has ever worked with django notifications had an issue like that? -

The question is how do I get the file that I got from request.FILE['file'] to upload to google drive? this my code user = request.user.social_auth.get(provider='google-oauth2') tfile = request.FILES['file'] drive = build('drive', 'v3', credentials=Credentials(user)) media_metadata = { 'name': tfile, 'parents': [folder.objects.filter(user__username=user)[0].id_folder] } media = MediaFileUpload(tfile, mimetype='image/jpeg') upfile = drive.files().create(body=media_metadata, media_body=media, fields='id').execute() -
Django - Can't import other app's model from same directory
I've got a problem with importing model from another app for Foreign key. I tried two ways to use field from other model: Import it as a string, it doesn't provide any errors before migrating model: from_city = models.ForeignKey('cities.City', blank=True, null=True, related_name='from_city_set', on_delete=models.CASCADE) It provides an error when i'm trying to use "makekigrations" or "migrate" command Import it as python object, but there is a strange moment. It tries to import 'city' app from src folder like that: from src.cities.models import City from_city = models.ForeignKey(City, blank=True, null=True, related_name='from_city_set', on_delete=models.CASCADE ) Both variants provides the same traceback: Traceback (most recent call last): File "C:\TrainProject\src\manage.py", line 22, in <module> main() File "C:\TrainProject\src\manage.py", line 18, in main execute_from_command_line(sys.argv) File "C:\TrainProject\venv\lib\site-packages\django\core\management\__init__.py", line 446, in execute_from_command_line utility.execute() File "C:\TrainProject\venv\lib\site-packages\django\core\management\__init__.py", line 440, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "C:\TrainProject\venv\lib\site-packages\django\core\management\base.py", line 402, in run_from_argv self.execute(*args, **cmd_options) File "C:\TrainProject\venv\lib\site-packages\django\core\management\base.py", line 448, in execute output = self.handle(*args, **options) File "C:\TrainProject\venv\lib\site-packages\django\core\management\base.py", line 96, in wrapped res = handle_func(*args, **kwargs) File "C:\TrainProject\venv\lib\site-packages\django\core\management\commands\makemigrations.py", line 196, in handle loader.project_state(), File "C:\TrainProject\venv\lib\site-packages\django\db\migrations\loader.py", line 361, in project_state return self.graph.make_state( File "C:\TrainProject\venv\lib\site-packages\django\db\migrations\graph.py", line 329, in make_state project_state = self.nodes[node].mutate_state(project_state, preserve=False) File "C:\TrainProject\venv\lib\site-packages\django\db\migrations\migration.py", line 89, in mutate_state operation.state_forwards(self.app_label, new_state) File "C:\TrainProject\venv\lib\site-packages\django\db\migrations\operations\models.py", line 724, in state_forwards state.alter_model_options( File "C:\TrainProject\venv\lib\site-packages\django\db\migrations\state.py", line … -
Django Unit Tests - Changes to self properties are persisting from test to test
I have a test class that has a setup like this. We import a dictionary from a test_helpers file that has some default data. The data is set as FORM_DATA['value_A'] = 0 and FORM_DATA['value_B'] = 1000000 from the start. Whether I set FORM_DATA to a self.form_data value, or assign it to a variable in each test, doesn't matter. The 2nd test seems to persist the dictionary changes from the 1st test, which is not ideal for testing. I added a bunch of print debug statements to show what is happening. Even in the setUp() for the 2nd test, it shows the values from the previous test! What is happening here? Why can't the dictionary self.form_data be the default imported data every time I have a new test? from test_helpers import FORM_DATA class TestBaselineScenarios(TestCase): @classmethod def setUpClass(cls): super(TestBaselineScenarios, cls).setUpClass() long_running_data_setup() def setUp(self): self.form_data = FORM_DATA print("setUp", self.form_data['value_A'], self.form_data['value_B']) def test_one(self): print("1") print(self.form_data['value_A'], self.form_data['value_B']) self.form_data['value_A'] = 25000 self.form_data['value_B'] = 700000 print("2") print(self.form_data['value_A'], self.form_data['value_B']) simulation = test_helpers.create_simulation(form_data=self.form_data) simulation.run() self.assertEqual(0.8416667, round(simulation.success_rate(), 7)) def test_two(self): print("3") print(self.form_data['value_A'], self.form_data['value_B']) self.form_data['value_A'] = 10000 print("4") print(self.form_data['value_A'], self.form_data['value_B']) simulation = test_helpers.create_simulation(form_data=self.form_data) simulation.run() self.assertEqual(0.9916667, round(simulation.success_rate(), 7)) setUp 0 1000000 1 0 1000000 2 25000 700000 setUp 25000 700000 3 25000 … -
