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? -

Django - Can't import other app's model from same directory

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 … -

Django-rest framework and Client Credentials grant type with no user
I am using the Django-rest framework for implementing a set of APIs using the Client Credentials grant type.The Client Credentials grant type is used by clients to obtain an access token outside of the context of a user. My " authenticate" method isn't tied to a user, nor should be. However, Django rest according to the documentation expects a user. "If no class authenticates, request.user will be set to an instance of django.contrib.auth.models.AnonymousUser, and request.auth will be set to None." This means that even tho my token is valid Django rest will still give permission denied. For example: class TokenAuthentication(BaseAuthentication): """ https://www.oauth.com/oauth2-servers/access-tokens/self-encoded-access-tokens/ """ keyword = 'Bearer' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.user_model = get_user_model() def authenticate(self, request): token = get_authorization_header(request).split() if not token or token[0].lower() != self.keyword.lower().encode(): return None if len(token) == 1: raise InvalidTokenHeaders() if len(token) > 2: raise InvalidTokenHeaders() token = token[1] unsigned_claims = self.decode_token_claims_no_key(token) client_id = unsigned_claims.get('sub',None) client = self.get_application_by_client_id(client_id=client_id) if client is None: raise InvalidToken() trusted_cliams = self.verify_token_cliams(token, client.client_secret) request.user = None request.auth = trusted_cliams.get('client_id') return request.user,request.auth -

Django - request.user returns AnonymousUser with custom user
I am having some problems on the authentication part for my Django app, using a CustomUser. The logic is the following: I need to send credentials (email/password) to an external API, from which I retrieve the access token which will be used on the later requests. During the process, I also create (or update, if it's already there) a CustomUser inside my local db, with the same credentials as in the external database. Then I try to authenticate the user in my app with the same credentials.

But i noticed later the 2 functions were similar. def upload_path(instance, fl_file_name): supplier = str(instance.fl_supplier).replace(' ', '-') return ('sources/{0}/{1}'.format(supplier.lower(), fl_file_name)) def upload_path_stock(instance, fl_file_name): supplier = str(instance.fl_st_supplier).replace(' ', '-') return ('sources/{0}/{1}'.format(supplier.lower(), fl_file_name)) A bit lower, my model was written like this class Flow(models.Model): [...] fl_file_name = models.FileField( max_length=50, upload_to=upload_path_stock, verbose_name='Nom fichier') I tried to comment the function def upload_path_stock and changed the property of my model like this : class Flow(models.Model): [...] fl_file_name = models.FileField( max_length=50, upload_to=upload_path, verbose_name='Nom fichier') # <<<< HERE But when saving, an error raised : File "/Users/[...]/migrations/0063_auto_20220822_1834.py", line 27, in Migration field=models.FileField(max_length=50, upload_to=flows.models.upload_path_stock, verbose_name='Nom fichier'), AttributeError: module 'flows.models' has no attribute 'upload_path_stock' This line prevents saving the file to be saved because upload_path_stock is mentioned there: migrations.AlterField( model_name='flowstock', name='fl_st_file_name', field=models.FileField(max_length=50, upload_to=flows.models.upload_path_stock, verbose_name='Nom fichier'), ), So I uncommented the unwanted function and proceed again with a new migration. Now the last migration is #64. But even though the migration 64 is applied, the error is still mentioned in the 63 when I comment out the function again and try to save my model. Can I modify the new path directly in migration 63 file or should … -
Spotipy not changing users
So I am making a Spotify statistics app which just shows some stats about the user's Spotify account using the Django and the Spotipy python module. I made the user's first name a required field and labeled it Spotify Username so that the user enters their Spotify username and it is stored in the users table as the first_name (I realize the flaws with this approach, I am just trying to get everything up and running). My problem is that no matter how many times I logout and switch users, the responses from the Spotify api don't change. Take for example this function: @login_required def recents(request): token = spotipy.util.prompt_for_user_token( username=request.user.first_name, scope=SCOPE, client_id=CLIENT_ID, client_secret=CLIENT_SECRET, redirect_uri=REDIRECT_URI) session = spotipy.Spotify(auth=token) recents = session.current_user_recently_played(limit=8) recents = recents["items"] return render(request, 'stats/recents.html', { "recents": recents }) I specify username=request.user.first_name but the recents page for every user shows the recent songs on my own Spotify account. I have a hunch that this is because my REDIRECT_URI is http://localhost:8080/ so it is automatically signing into my own account, however I'm not sure.
