Streaming LLM output in Django
Im planning to develop Django framework for the LLM fine-tuned model based on HuggingFace models, I want the text to be streamed from model to the Django. My issue is that model streams the output in the terminal but not sure how to make it in a stream in a variable so that I can transfer it to the end-user I tried using pipeline with TextStream but it only output the text in the terminal model_id = "model_a" model = AutoModelForCausalLM.from_pretrained( model_id, torch_dtype=torch.bfloat16, device_map="auto", trust_remote_code=True, # attn_implementation="flash_attention_2" ) tokenizer = AutoTokenizer.from_pretrained( model_id, trust_remote_code=True ) streamer = TextStreamer(tokenizer) pipeline = pipeline( "text-generation", model=model, tokenizer=tokenizer, model_kwargs={"torch_dtype": torch.bfloat16}, streamer=streamer ) -
Why no pip packages accessible from any new directory wheras it is accessible from existing directories while in venv
I am working on a Django project. Recently while working on my new project, I had to delete py an open project folder. Now I am not able to access the list of pip packages from any of the newly created directories except being shown pip version number when I activate venv. However the pip list is accessible from any of the previously created directories even if create a venv in that foldeer and activate that venv. My file directory structures are as given below: pip list accessible in records_log folder of the following directory: C:\Users\abc\Projects\Python_proj_1\Python_proj_ml\records_log pip list is not accessible in newly created sub directory projects_practice folder: C:\Users\abc\Projects\Python_proj_1\Python_proj_ml\projects_practice\records_log The mini conda is installed at the following location: C:\Users\abc\miniconda3 I am able to mitigate this issue by changing the following line in pyvenv.cfg to True, which is supposed to remain default remains 'false' in all normally working directories. include-system-site-packages = true But as I know that there is something amiss. I do not wish to resort to using this work around like the one mentioned above. I need help to fix this issue and get the system as it was before I deleted the project file which led to this … -
Django form with MediumEditor not honoring required attribute
In Django, I have a TextField called 'description' in a model with null and blank set to False (for server side and client side validation). I'm using forms.ModelForm to pull the field and I'm using forms.Textarea to assign attributes. In the attributes, I'm assigning the medium-editor-textarea class attribute to leverage MediumEditor. This field is working as intended and the MediumEditor js is indeed called so that a user can leverage the MediumEditor wysiwyg in the text area; I also have a script in my form template that initializes a new instance of the MediumEditor class with all elements that have the class 'editable': var editor = new MediumEditor('.editable');. The one problem I'm having is that while the div and textarea both contain the required attribute, this is not prompting on the client side that this field is required when a user submits the form. Rather, I continually get the following error message in the console: An invalid from control with name='description' is not focusable, and this points to the textarea tag. In short, even with the required attributes, the browser prompt that the field cannot be empty is not firing on the client side. Here is the relevant code, trimmed … -

Django rest framework's ModelSerializer missing user_id field causing KeyError
My ModelSerializer is getting a KeyError when I call .data on the serializer and I'm not sure how to properly fix this error. Knox's AuthToken model looks like this class AuthToken(models.Model): objects = AuthTokenManager() digest = models.CharField( max_length=CONSTANTS.DIGEST_LENGTH, primary_key=True) token_key = models.CharField( max_length=CONSTANTS.TOKEN_KEY_LENGTH, db_index=True) user = models.ForeignKey(User, null=False, blank=False, related_name='auth_token_set', on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True) expiry = models.DateTimeField(null=True, blank=True) def __str__(self): return '%s : %s' % (self.digest, self.user) I created a Model serializer class AuthTokenResponseSerializer(serializers.ModelSerializer): class Meta: model = AuthToken fields = "__all__" However, when I create a token_serializer, I get this error >> token_serializer.data *** KeyError: "Got KeyError when attempting to get a value for field `user` on serializer `AuthTokenResponseSerializer`.\nThe serializer field might be named incorrectly and not match any attribute or key on the `dict` instance.\nOriginal exception text was: 'user'."

Django - Editing/updating records on formset triggering duplicate error
In Django, I have this FBV that updates selected records: def edit_selected_accountsplan(request): selected_items_str = request.GET.get('items', '') selected_items = [int(item) for item in selected_items_str.split(',') if item.isdigit()] accountsplan_to_edit = AccountsPlan.objects.filter(id__in=selected_items) AccountsPlanFormSet = formset_factory(form=AccountsPlanForm, extra=0) if request.method == 'POST': formset = AccountsPlanFormSet(request.POST) if formset.is_valid(): for form, accountplan in zip(formset, accountsplan_to_edit): accountplan.subgroup = form.cleaned_data['subgroup'] accountplan.name = form.cleaned_data['name'] accountplan.active = form.cleaned_data['active'] accountplan.save() return redirect('confi:list_accountsplan') else: initial_data = [] for accountplan in accountsplan_to_edit: initial_data.append({ 'subgroup': accountplan.subgroup, 'name': accountplan.name, 'active': accountplan.active, }) formset = AccountsPlanFormSet(initial=initial_data) return render(request, 'confi/pages/accountsplan/edit_selected_accountsplan.html', context={ 'formset': formset, }) Everything works as expected (the page loads, the form is filled correctly etc.) except when saving the data. The 'name' field is defined as unique in the database, so when I try to change other fields but don't change the name, it gives me a duplicate error. If I change the name to anything else that is not already in the database, it updates the current name correctly, so it's not creating a new record. I've tried to change the loop block to this just to see if I could save: for form, accountplan in zip(formset, accountsplan_to_edit): form.instance = accountplan form.save() return redirect('confi:list_accountsplan') But again, the duplicate error is triggered. I don't understand why this … -

Static files path generated incorrectly in Django project
Description: In my Django project, the static files path is generated incorrectly, appending the current page URL before the static URL. For example, when I'm on the about page, the path becomes http://127.0.0.1:8000/about/static/images/bg/17.jpg instead of http://127.0.0.1:8000/static/images/bg/17.jpg. This causes issues with serving static files. How can I debug and fix this issue? STATIC_URL = '/static/' #Location of static files STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static/'), ] MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), path('', include('home.urls')), ]+static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) I've checked my settings.py file and ensured that STATIC_URL = '/static/'. My static files are located in the correct directory (static/images/bg/17.jpg). I'm using the {% static %} template tag in my templates to reference static files. I've also run collectstatic after making changes to my static files. Expected Behavior: I expect the static files path to be generated as http://127.0.0.1:8000/static/images/bg/17.jpg regardless of the current page URL. -
Nginx + React + Django: Understanding CORS Request Headers
I'm hosting a React frontend app and Django backend API on Nginx in a single local Raspberry Pi, on ports 80 and 8000, respectively, with the following config: // REACT APP server { listen 80; listen [::]:80; root /link-to/build; index index.html; server_name pinode; location / { try_files $uri /index.html; } } // Django APP/Gunicorn server { listen 8000; server_name localhost; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /link-to/myproject; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } For my use case, I'd like all internal requests between react and django to use localhost. However, the user can access the react front end using the Raspberry Pi's hostname (in this case, http://pinode/ as seen in nginx config above). In react, all API calls use http://localhost:8000/api/*. During my testing of the above, I had some level of success. However, one of the following always fails exclusively: During login, I get a response from http://localhost:8000/api/login/, but the Set-Cookie fails due to Cross-Site policy. Attempting to add headers to nginx backend config results in requests being rejected due to CORS policy. Post requests are rejected due to a missing csrftoken, despite axios is setup with X-CSRFToken header … -

Forbidden (CSRF cookie not set.) when trying to connect from a desktop app
I'm developing a desktop application where users can log in using credentials from my Django website's database. The goal is for users to be able to create posts on the Django website (forum) through the desktop application.

Pipenv skipped update of package, Django 4.2 -> 5

Django-Oscar / Can't subscrive templates from costumer folder
I'm using django and oscar to create an ecommerce site. I'm trying to add allauth, and i need to add buttons to login_registration.html template. I set the templates dir to my custom template folder and already subscrived the oscar/base.html template and oscar/partials/brand.html template without any issue. Now i'm trying to subscrive the oscar/costumer/login_registration.html template but without any success. It simple does not go into my templates/oscar/costumer folder to look for the login_registration.html first, no matter what i do. I've tried deleting the original oscar login_registration.html to force it to look in my custom templates folder, no joy. I've tried with other html files from original oscar costumer folder, no joy. I've tried cleaning the cache, no joy. It works fine when subscriving base.html and partials/brand.html, but not inside costumer folder. -

Can't pass instance while creating an DB entry in django
I have two models, DocumentData & RecurringInvoice, which have a one to one relationship with each other. When I create an entry in the RecurringInvoice table, I want to pass in the DocumentData instance, instead of the id. But I get an error saying: {'document_data': [ErrorDetail(string='Incorrect type.

Models.py: class File(models.Model): topic = models.ForeignKey(Topic, related_name='files', on_delete=models.CASCADE, null=True) submission = models.ForeignKey(Submission, related_name='files', on_delete=models.CASCADE, null=True) filename = models.FileField(upload_to='submissions/', null=True) upload_date = models.DateTimeField(auto_now_add=True) is_accepted = models.BooleanField(default=False) def __str__(self): return f"File: {self.filename.name} for Topic: {self.topic.name}" Forms.py: class UploadFileForm(ModelForm): class Meta: model = File fields = ('filename',) Views.py: def upload_file(request, subm_id, topic_id): submission = get_object_or_404(Submission, pk=subm_id) topic = get_object_or_404(Topic, pk=topic_id) form = UploadFileForm() context = {'submission':submission, 'topic':topic, 'form': form} if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): file_instance = form.save(commit=False) file_instance.topic = topic file_instance.submission = submission file_instance.save() messages.success(request, 'File succesfully uploaded') return redirect('upload_file', subm_id=submission.id, topic_id=topic.id) else: print(request.FILES) messages.error(request, 'No file was uploaded') form = UploadFileForm() return render(request, 'users/upload_file.html', context=context) Settings.py: MEDIA_URL = '/media/' MEDIA_ROOT = BASE_DIR / 'media' Template: <form method="POST" action="" enctype="multipart/form-data"> {% csrf_token %} <div class="mb-3"> <label class="form-label" for="{{ form.filename.id_for_label}} " >Загрузите файл</label > {{ form|crispy }} </div> <input class="btn btn-secondary" type="submit" value="Submit" /> </form> What could be causing …
