how to use the ‘problems’ field in pycharm?
pycharm keeps finding ‘problems’ in the project. it's all completely useless and unfounded. don't know how it works. does anyone use it ? for example, here he found an ‘indent expected’ problem and here's the code: class ProductForm(forms.ModelForm): or here, there's a mistake in the middle of nowhere. code: And so on throughout the project. found 18 errors, looked through each one - all to no avail. is it me who doesn't know how to use it, or it doesn't work? does anyone use it? -
How check if user is logged in on server side React, Django, JWT
I have set up authorization using the JWT token. Now I want to give the user access to the protected view, which requires authorization. class GetUser(APIView): authentication_classes = [JWTAuthentication] permission_classes = [IsAuthenticated] def post(self, request): return Response({'username': request.user.username}) How do I check if the user is logged in on the server side? I wrote an asynchronous function that accesses the django rest framework api. But this function always returns a promise no matter what I do. function saveToken(data) { localStorage.setItem('access_token', data.access) localStorage.setItem('refresh_token', data.refresh) return true } async function isLoggedIn() { return await axios.post('api/getuser/', {}, {headers: {Authorization: 'Bearer ' + localStorage.getItem('access_token')}}) .then(async function (response) { return true }) .catch(async function (error) { return await axios.post('api/token/refresh/', {refresh: localStorage.getItem('refresh_token')}) .then(async function (response) { return saveToken(response.data) }) .catch(async function (error) { return false }) }) } As I understand it, I can't get the value from promise in any way. That's why I decided to write the component this way, but React throws an error. const ComponentMainArea = () => { const location = useLocation() const element = useOutlet() return isLoggedIn().then((value) => { if (!value) { return (<Navigate to="/proxy/8000/login"/>) } else { return ( <div className='mainarea'> <AnimatePresence mode='wait' initial={true}> {element && React.cloneElement(element, { key: … -
https to http nginx works partially
I can use http and https connection to my router(to which connected server) through KeenDNS. I have nginx with following config on the server server { listen 80; server_name example.com; location /static/ { alias /app/staticfiles/; } location / { proxy_pass http://web:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } } so when I go to /static/ urls over https everything works, but / urls doesn't and I'm getting 400 bad request. Btw I'm having Django in docker with gunicorn behind proxy_pass's web url. Over http everything works fine. What could be the problem? -
Supporting Apple sign-in for mobile and web using dj_rest_auth, allauth
We are looking to implement Apple sign-in from both the web and mobile using this stack. React SPA using Django 4.2 / DRF 3.15.2 / dj_rest_auth 6.0.0 / allauth 0.61.1 backend Due to the different Client ID for web and mobile, we had to configure two separate apps in SOCIALACCOUNT_PROVIDERS[”apple”] as recommended by allauth. To make this work for the version we are using, we had to manually apply the following patch to 0.61.1 and set the “hidden” property on the mobile app. My impression was that this property is needed to make it work with some admin interface, but maybe not. The explanation is not clear - “For the app specifying the bundle ID, add the following to the settings so that this app does not show up on the web”. We use the same settings for both APPS - secret, key, settings, except for client_id. When we set this property, the “hidden” app (mobile) never gets used and we get a client_id mismatch error when logging in from mobile. So I guess I am not sure I understand the purpose of having that property. Or maybe we are missing some other patch(es) that make this work. In short, … -
Memory Leak When Using Django Bulk Create
I have the following code that constantly checks an API endpoint and then if needed, adds the data to my Postgres database. Every iteration of this loop is leaking memory in the postgresql\operations.py file. Im not sure what data is still being referenced and isnt clearing, so realistically what could be causing this issue? class DataObject(models.Model): raw_data = models.TextField() name = models.TextField(null=True) def post_process(self): data = json.loads(self.raw_data) self.name = data['name'] def do_from_schedule(): api = API() loads = api.grab_all_data() del api datas_to_create = [] for load in loads: data = DataObject() data.raw_data = json.dumps(load) data.post_process() datas_to_create.append(data) DataObject.objects.bulk_create(datas_to_create, ignore_conflicts=True, batch_size=200) del datas_to_create gc.collect() while True: do_from_schedule() time.sleep(5) Here are the results of tracemalloc. Theres a consistent, and unending memory leak. #1: postgresql\operations.py:322: 156.9 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 235.3 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 313.7 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 392.0 KiB return cursor.query.decode() #1: postgresql\operations.py:322: 470.4 KiB return cursor.query.decode() I found this for someone using MySql https://stackoverflow.com/a/65098227/8521346 But im not sure how to even test/ fix this if it was the issue with the postgres client. -

Inline Images Displayed as Attachments in iOS Mail App
I'm using Django to send HTML emails that include an inline logo image using the cid (Content-ID) method. The email is sent and rendered correctly in most email clients, but in the iOS Mail app, the logo appears also as an attachment at the bottom of the email and than inline within the HTML content. Additionally, the attachment icon is visible in the email list view. Here is the code I’m using (Written in Python/Django): from django.core.mail import EmailMultiAlternatives from email.mime.image import MIMEImage # Sending the email email = EmailMultiAlternatives( subject=subject, body=html_content, from_email=from_address, to=to_email ) email.attach_alternative(html_content, "text/html") # Adding logo as inline attachment with open(self._get_logo(domain), 'rb') as logo_file: logo = MIMEImage(logo_file.read()) logo.add_header('Content-Disposition', 'inline') logo.add_header('Content-ID', '<logo>') # Important: Set CID here email.attach(logo) In the HTML content, I reference the image like this: <img src="cid:logo" alt="Logo"> Is there a known workaround or a specific way to ensure that inline images are displayed correctly in the iOS Mail app without showing them as attachments? Any advice on handling this issue within Django or HTML emails in general would be greatly appreciated. -

How to resolve web app on azure portal gives sometimes the error: Is the server running on host "localhost" (127.0.0.1) and accepting..?

How to use self-singed certificates on DDG iOS browser
I cannot access a local website I built with Django on my iPhone using DuckDuckGo browser because it does not trust the self singed certificate even though I manually installed it on my iPhone. The error message that I get says: "The certificate for this server is invalid. You might be connecting to a server that is pretending to be "192.168.1.128" which could put your confidential information at risk." I used mkcert on my macBook to generate the certificate, uploaded it to the “server” (everything is running locally on my macBook) and installed it on my iPhone. When using Safari everything is working fine. The certificate is a .pem file. After researching the internet, I tried to follow these instructions on apple.stackexchange.com - but I don’t have the option to "Enable full trust for root certificates" for the newly-installed certificate as it is shown here on support.apple.com. -
Docker fist implementation: not showing Angular frontend
I am trying to set up Docket in this stack: Angular 18.2, Python 3.12.5, Django 5.1, Posgres 16.4. I tried setting up a Dockerfile in each of the Backend and Frontend folders, also I created docker-compose.yaml and .dockerignore in the root folder. After solving various problems it seems to be working, the problem is that I can't see the frontend DOM. The localhost is not reachable. But if I try to run the payers separately I am able to see. So I definitely made some mistakes along the way. I share the files and the folders tree.

Django ORM - Prevent null field being included in the insert statement
I have a Django model resembling the following: class SomeClass(CoreModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) auto_increment_id = models.BigIntegerField(null=True, blank=True, db_index=True) I want to increment the auto_increment_id field directly in the database using DEFAULT value. In fact I modified my table in the test db and when I manually insert a row, this works as expected. When I insert a new record through Django though, this field remains as Null, because the SQL that Django produces includes this field as well with a NULL value. I've tried setting this field to a BigAutoField but it seems this field should be used as a primary key and since I have another primary key, this is not an option. Needless to say, this is a production code and I cannot change my primary key. Any methods to prevent this behaviour? -
Django Form Wizard Not Executing done() Method Despite Valid Form Submission
I’m using the SessionWizardView to implement a multi-step form process for signing documents. However, I’m encountering a perplexing issu where the done() method is not being executed, and as a result, no data is being saved to the database. Im using django 5.0.6. The form process involves 3 steps: User inputs personal details User reviews the document title and details User signs the document, and the signed document should be saved Now after submitting the final form (Step 3), the wizard redirects to the thank_you page as expected. However, none of the participant data, including the signed document, is saved to the database. Additionally, the done() method does not seem to be executed, as none of the print statements or debugging logs inside this method appear in the console.Here is the current implementation of the SignMyselfWizard view: class SignMyselfWizard(SessionWizardView): form_list = FORMS_MYSELF file_storage = file_storage def get_template_names(self): step = self.steps.current if step == 'user_details': return 'sign/user_details_form.html' elif step == 'review': return 'sign/review_document.html' elif step == 'sign_document': return 'sign/sign_myself_wizard.html' return 'sign/default.html' def get_context_data(self, form, **kwargs): context = super().get_context_data(form=form, **kwargs) if 'unique_link' in self.kwargs: document = get_object_or_404( Document, unique_link=self.kwargs['unique_link']) context.update({ 'document': document, 'document_url': self.request.build_absolute_uri(document.docfile.url), 'company': document.company, }) if self.steps.current == 'sign_document': user_details … -
Django migrates data, and an error is reported during the migration, but a table appears in the database, what is going on?
I will connect to three MySQL databases, generally connect to the local database, and then test the database, and there is the online database, if I connect to the local database migration model to generate the migration data successfully, but when I connect to the online database, the field is displayed when the data is migrated (it is a failure during migration), but the corresponding table is generated in the online database, and then I use MySQL When I execute the python manage.py migrate command again, it will show that the table already exists, and it stands to reason that these generated tables will not be recognized by Django, how should this problem be solved? I tried to use --fake to get him to force the endorsement, but it still failed, and now it shows that this table already exists, and deleting the table is not good to delete because of the online database I have a version of Django that is 3.2.3 -
