How do i record an audio in .wav file format that would meet the standard of Google Speech To Text API in React Native Expo
I have a function that starts and stops recordings, when the recording stops, i can playback the recording and everything works well, but whenever I upload the audio file to Google for transcription, I get an empty response. But when i upload another .wav file (downloaded online, not the recording). I get the transcription of that audio. const startRecording = async () => { try { console.log("Requesting permissions.."); const { status } = await Audio.requestPermissionsAsync(); if (status !== "granted") { alert("Sorry, we need audio recording permissions to make this work!"); return; } console.log("Starting recording.."); await Audio.setAudioModeAsync({ allowsRecordingIOS: true, playsInSilentModeIOS: true, }); const { recording } = await Audio.Recording.createAsync({ android: { extension: ".wav", outputFormat: Audio.RECORDING_OPTION_ANDROID_OUTPUT_FORMAT_DEFAULT, audioEncoder: Audio.RECORDING_OPTION_ANDROID_AUDIO_ENCODER_DEFAULT, sampleRate: 16000, numberOfChannels: 1, bitRate: 128000, }, ios: { extension: ".wav", audioQuality: Audio.RECORDING_OPTION_IOS_AUDIO_QUALITY_HIGH, sampleRate: 16000, numberOfChannels: 1, bitRate: 128000, linearPCMBitDepth: 16, linearPCMIsBigEndian: false, linearPCMIsFloat: false, }, }); setRecording(recording); } catch (err) { console.error("Failed to start recording", err); } }; const stopRecording = async () => { console.log("Stopping recording.."); if (recording) { await recording.stopAndUnloadAsync(); const uri = recording.getURI(); setRecording(null); uploadAudio(uri); } }; function getOtherUser(data, username) { if (data.receiver.username !== username) { return data.receiver; } if (data.sender.username !== username) { return data.sender; } return null; } … -

Django OperationalError: MySQL Connection not available
I am encountering an issue while trying to connect my Django project to a MySQL database hosted on cPanel using "mysql-connector-python". Despite configuring the settings correctly, I consistently receive an OperationalError: MySQL Connection not available when attempting to run my Django application. Database Settings in settings.py: DATABASES = { 'default': { 'ENGINE': 'mysql.connector.django', 'NAME': 'the name', 'USER': 'the user', 'PASSWORD': 'the pass', 'HOST': 'localhost', 'PORT': '3306', } } I am using mysql-connector-python version 8.4.0 to connect to the MySQL database. Verified database credentials and ensured they match those configured in cPanel. Checked MySQL server status and confirmed it is running without issues. Error Message: django.db.utils.OperationalError: (-1, 'MySQL Connection not available.', None) The Django application and MySQL database are hosted on separate servers, with cPanel managing the MySQL instance. The MySQL user has been granted all privileges (ALL PRIVILEGES) for the specified database. -
Serving media files in Django using whitenoise for simple blog application
I am building a simple blog application where only I would be uploading the images and text of the blog from admin dashboard. I used whitenoise in production, with static files like css js and logo images etc. were loading correectly, but the media files of the blog were not being served. I explore the web and got to know that due to security considerations, static files and media files are separated with media files being loaded from storage services like S3 bucket etc. But in my case, only me, not any external user would be uploading the images for the blog from admin dashboard, so the security risk doesn't seem to apply here. (correct me if I am wrong here). So, to serve the media files from whitenoise what I did was to make static root and media root as same location, and used {% static %} to serve the blog images instead of media url. Now the application is working as it should, but I am concerned whether this approach is suitable in the long run or not. Please advise if there is any downside of using this approach for simple application like blogging websites. -
Admin page not found (404) in Django project?
I'm using a shared hosting with cPanel but without Terminal access. It was hard to find tutorial for this situation. After struggling to make it work. The website shows the home page at : https://mywebsite.com but not found (404) for the url: https://mywebsite.com/admin or https://mywebsite.com/admin/ I didn't touch anything in urls.py. The homepage is showing the famous green rocket and the message "The install worked successfully! Congratulations!" What I did is to run manage.py migrate and collectstatic and set STATIC_ROOT = 'home/mywebsite/dj/static/' in setting.py. But all of the above haven't improve the situation. Feel free to edit or improve the title of my question. -
Is it possible to change the url in view (Django) after a certain operation?
Let's say there is a page of a separate blog article with this url (aviary-ensemble is the slug of the article): http://127.0.0.1:8002/articles/article/aviary-ensemble/ Now I'm making a comment system and the form for writing a comment is on the same page. The view for creating a new comment I have formalized as follows: if there is no submitted data, then load the page, if there is - then based on this data create a comment and load the page. def details(request, slug, author=None): article = models.Article.objects.get(slug=slug) print(author) if request.method == 'POST': if author is not None: user = User.objects.get(username=author) print(user.username, type(user)) comment_author = UserProfile.objects.get(user=user) comment = request.POST['comment_area'] if comment[0] == '@': receiver = comment[1:].split(', ')[0] comment_text = comment[1:].split(', ')[1] models.Comment.objects.create(article=article, author=comment_author, receiver=receiver, text=comment_text) else: models.Comment.objects.create(article=article, author=comment_author, text=comment) article_comments = models.Comment.objects.filter(article=article) context = { 'article': article, 'article_comments': article_comments } return render(request, 'articles/article.html', context=context) else: article.views = article.views + 1 article_comments = models.Comment.objects.filter(article=article) context = { 'article': article, 'article_comments': article_comments } return render(request, 'articles/article.html', context=context) I set the url itself as follows: urlpatterns = [ path('', views.index, name='articles_catalog'), path('article/<slug:slug>/<str:author>/', views.details, name='comment_creation'), path('article/<slug:slug>/', views.details, name='details'), ] The nuance is that after submitting the form the url changes to http://127.0.0.1:8002/articles/article/aviary-ensemble/admin/ (admin is the username of … -

reasons for using rust api over django, node?
Has anyone made a large scale rust web api and if so why did you choose it over easier languages like python. Is there significant performance, lower response times, concurrency, etc from using rust compared to python or is it negligible. Assume we’re talking about a social media app which wouldnt be heavy mathematically. It was suggested to me that a web api is dominated by the speed and efficiency of database operations and this using a faster language like rust compared to python has negligible benefits in real world, is this true in your experience? -

API for dota player information using Django
Good afternoon, I might be mistaken as I am new to Django and API, but hopefully someone can correct me if I am wrong. I have this task to create a webpage here is the sample https://impactosolardota.com/.

As far as my understanding goes, I need an API to send information from another website to mine. My plan is to build a Django website and the frontend in React. However, I am starting to think that I might not need Django at all and maybe do only with React?. -
Django Admin automatically logs me out when i click the save button and won't allow me log in again
Whenever I click the save button to add user on the django admin interface, it automatically logs me out and won't re-authenticate me despite being the superuser.

I tried clearing the browser cache or opening the page in an incognito/incognito window. -
How to make content fetched during login persist even if the user logs out and logs in again?
I currently am working on a project where a user authenticates, and when they are redirected to the home page, a GET request to an API is made: def home(request): url = f'https://icanhazdadjoke.com/' headers = { "Accept": "application/json" } #Putting the application/json in the header to get a JSON result r = requests.get(url,headers=headers) #Making a get request to get a random dad joke data = r.json() #Converting JSON data to a python dictionary required_joke = {'joke': data['joke']} return render(request,'test_section/Home.html',required_joke) Now, I mainly have two requirements: When the user presses the refresh button, a new joke should be generated (satisfied). If the user logs out, and logs back in again, the same joke that was being shown on the screen previously should be shown. For example, if the user logs out now, and logs back in, he should see this same joke displayed. I will be very grateful if someone can guide me regarding how to tackle this. It looks simple but I do not understand where to start. -
Updating a django table, hashing a specific field in a table
I have a table that looks something like class PodUsage(models.Model): pod_id = models.CharField(max_length=256, db_index=True) pod_name = models.CharField(max_length=256) start_time = models.DateTimeField(blank=True, null=True, default=timezone.now) end_time = models.DateTimeField(blank=True, null=True) anonymised = models.BooleanField(default=False) user = models.ForeignKey("accounts.ServiceUser", null=True, blank=True, on_delete=models.CASCADE) As part of our GDPR requirement, we need to anonymize data after a certain period, which I could absolutely do as a loop: count = 0 records = PodUsage.objects.filter( anonymised=False, start_time__lte=timezone.now() - timedelta(weeks=settings.DATA_ANONYMISING_PERIOD_WEEKS) ) for record in records: record.pod_name = hashlib.sha256(record.pod_name.encode('utf-8')).hexdigest() record.user = None record.anonymised = True record.save() count += 1 # Log count somewhere however I think I should be able to do it with an update function: count = PodUsage.objects.filter( anonymised=False, start_time__lte=timezone.now() - timedelta(weeks=settings.DATA_ANONYMISING_PERIOD_WEEKS) ).update( pod_name = hashlib.sha256(pod_name.encode('utf-8')).hexdigest(), user = None, anonymised = True ) # Log count somewhere ..... but I can't figure out the correct incantation to reference the field in the update portion as given, pod_name is not defined sha256("pod_name".encode('utf-8')) obviously just encodes the string "pod_name" sha256(F("pod_name").encode('utf-8')) breaks the code with 'F' object has no attribute 'encode' Any suggestions? -
Django: Preload query from django-simple-history
I need to preload the update history queries saved with django-simple-history, to significantly improve the query execution time, for example, I have these models in my application: class Staff(models.Model): registration = models.CharField(max_length=100, unique=True) identification_type = models.CharField(max_length=2, choices=( ('V', 'V'), ('E', 'E'), ('J', 'J') ), default='V') identification_number = models.CharField(max_length=100, unique=True) first_names = models.CharField(max_length=100) last_names = models.CharField(max_length=100) birth_date = models.DateField() hire_date = models.DateField() hire_date_to_public_administration = models.SmallIntegerField(default=0) termination_date = models.DateField(null=True) sex = models.CharField(max_length=10, choices=( ('F', 'Femenino'), ('M', 'Masculino') )) address = models.TextField() marital_status = models.CharField(max_length=15, choices=( ('Soltero/a', 'Soltero/a'), ('Casado/a', 'Casado/a'), ('Divorciado/a', 'Divorciado/a') )) education_level = models.CharField(max_length=100) department = models.ForeignKey( Department, on_delete=models.RESTRICT, related_name='staffs' ) position = models.ForeignKey( Position, on_delete=models.RESTRICT, related_name='staffs' ) payroll_type = models.CharField(max_length=10, choices=[ ('Empleado', 'Empleado'), ('Obrero', 'Obrero'), ], default='Empleado') worker_type = models.CharField(max_length=10, choices=[ ('Fijo', 'Fijo'), ('Contratado', 'Contratado'), ('Pensionado', 'Pensionado'), ('Jubilado', 'Jubilado'), ], default='Contratado') status = models.CharField(max_length=100, choices=( ('Activo', 'Activo'), ('Inactivo', 'Inactivo'), ), default='Activo') bank = models.CharField(max_length=100) bank_number = models.CharField(max_length=100) concepts = models.ManyToManyField( Concept, related_name='staffs', blank=True ) salary = models.DecimalField(max_digits=8, decimal_places=2) children_number = models.SmallIntegerField(default=0) is_disabled = models.BooleanField(default=False) receive_complement = models.BooleanField(default=False) history = HistoricalRecords() class Meta: ordering = ['identification_number'] class Payment(models.Model): date = models.ForeignKey( Calendar, on_delete=models.RESTRICT, related_name="payments" ) staff = models.ForeignKey( Staff, on_delete=models.RESTRICT ) total = models.DecimalField(max_digits=8, decimal_places=2, default=0) total_deduction = models.DecimalField(max_digits=8, decimal_places=2, default=0) … -
creating custom validators for fields in Django REST framework serializers.Serializer
I am writing a serializer for a complicated put API with a large validate function. To simplify the logic and make it more readable, I want to create validators for individual fields (I want to make my serializer class as small as possible and hence don't want to write individual validate methods for each field). I am passing context to my serializer from the view and each of my fields share a common context. I want to use that context in the validator to perform the required checks. This is how I am attempting to create custom validators: My validator class: class MyCustomValidator: requires_context = True def __call__(self, value, serializer_field): context = serializer_field.context print(f"got this context: {context}") my serializer: class MySerializer(serializers.Serializer): my_field = serializers.IntegerField(required=True, validators=[MyCustomValidator()]) sending context in my view: def get_serializer_context(self): context = super().get_serializer_context() context.update({'test_context': {'key': 'value'}}) return context But when I am calling this API, I get the following error: __call__() missing 1 required positional argument: 'serializer_field' Can someone please tell me what am I missing here? Thank you...
