CommandError: No fixture named 'fixture' found
I'm trying to use loaddata to load some fixtures into a Django 2.2.10 project. According to the documentation, the command should look like this: python manage.py loaddata fixture app/fixtures/*.json However, when I run this command I get the following error: CommandError: No fixture named 'fixture' found. I figured the word "fixture" was being interpreted as a path to the fixture, so I removed it and it worked: python manage.py loaddata fixture app/fixtures/*.json I still find it weird though that the documentation tells me to do something that doesn't work. Am I missing something? I'm worried that I might have something wrong in my setup that is going to come back to haunt me in the future. -

How to convert drop down choice column to text field in Django forms

Django migrations with Docker compose and volumes
I am using Django with Docker compose and all the persistent files are saved in a volume. My issue is that I am also saving my database in the volume: how does this influence migrations? I've added an new schema and there seems no way to reflect this change in the DB. When I apply the migrations on my local environment, it works, the migrations are correctly applied and I can see the new db schema, but this is because I've created a local folder app/static, which reflects the volume name of the docker-compose. Now, since the db is in that folder, it works, as the migrations are applied to the db. When I deploy my application, the db inside of the app/static remains the same old db, with the same old entries and the same old schemas. How can I apply the migrations so that the db inside of the volume app/static reflects the new changes, without losing the old entries? As a practical example I have added a new model Action, which is not existent on the server. So the DB has all the schemas but Action. Locally, I run makemigrations and migrate, producing the migration files (which … -

Python regEx won't identify whitespace
I'm trying to replace some keywords in a document using Django Template, but unfortunately i'm dealing with normal user data, so my function receives a dictionary with keys that i'm pretty sure will contain a space. To deal with this risk i'm trying to do this workaround using regEx: from typing import Dict, List from django.template import Context, Template import docx from docxcompose.composer import Composer import re import django from django.conf import settings settings.configure(TEMPLATES=[ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['.'], 'APP_DIRS': False }, ]) django.setup() def combine_documents(documents: List[dict], template_data: Dict): document_paths = [] placeholder = docx.Document() composer = Composer(placeholder) for i in range(len(documents)): document_paths.append(docx.Document(documents[i]["path"])) composer.append(document_paths[i]) composer.doc.add_page_break() context = Context(template_data, autoescape=False) document = composer.doc pattern = re.compile(r"\{{[\s\S]*\}}", re.IGNORECASE) for paragraph in document.paragraphs: for word in paragraph.text.split(): matches = pattern.finditer(word) # print(word) for match in matches: print(match.group()) if " " in match.group() and match.group() == word: print(match.group()) print("it's here") paragraph.text = paragraph.text.replace(" ", "_") template = Template(paragraph.text) print(template.render(context)) return "Ok!" combine_documents(documents = [{ "title": "Titulo", "path": "libs/plugins/signature/signature_providers/documents/Contrato de Prestação de Serviço - Exemplo.docx" }, { "title": "Outro título", "path": "libs/plugins/signature/signature_providers/documents/Contrato de Prestação de Serviço - Exemplo.docx" }], template_data={"Empresa": "FakeCompany", "Endereço Completo": "Rua 1", "Cidade": "São Paulo", "Estado": "São Paulo", "CEP": "12345678", "CNPJ": "317637667-0001", … -
Getting forbidden error when fetching endpoint when logged into account
Using React for the frontend and Django for the backend. I have a page in my website that displays all the user settings. When they load the page it fetches the data from the backend and fills out the form, when they submit the updated form it posts it to the backend. When I go to post this data when I'm logged into an account it gives me a forbidden error but when I'm logged out and post the form it goes through. Why would it be doing this? react post const onSubmit = async (e) => { e.preventDefault() const res = await fetch('/api/account/updatesettings', { method: "POST", headers: { 'Content-type': 'application/json' }, body: JSON.stringify({ "test": "test" }) }) const data = await res.json() } api endpoint: class UpdateSettings(APIView): serializer_class = AccountSettingsSerializer def post(self, request, format=None): print("test") serializer = self.serializer_class(data=request.data) print(serializer.data) if serializer.is_valid(): pass -
Transcribe Streams of Audio Data in Real-Time with Python
I developed a web app using Django as a backend and a Frontend library. I have used django-channels, for WebSocket and I am able to record the audio stream from the front end and send it to Django over WebSocket and then Django sends it to the group. So I'm able to do live audio calls (let's say) but I have to transcribe the audio at the backend. (the main goal of the project) Things I'm looking forward to use this package to achieve transcription. I send base64 encoded opus codecs string from the front end to Django every second. It sends recorded audio every 1 second. My doubts - If we play Audio streams independently, we are only able to play the first string. We are not able to play 2nd, 3rd .... independently (padding issues or maybe more I'm not aware of), so I have used MediaSource at front end to buffer the streams and play. The question is can we convert this 2nd 3rd audio stream into text using the above-mentioned package? or I will have to do something else. (I'm looking for ideas here on how will this work) Also, the above-mentioned package uses a wav …
