How do I resolve "Serverless Function has exceeded the unzipped maximum size of 250 MB" error on Vercel?
I have a personal project that I am building in Python using Django. When deploying it to Vercel, it worked fine until eventually the amount of libraries that I imported (included in my requirements.txt file) became too large, I assume, and now I face the "Serverless Function has exceeded the unzipped maximum size of 250 MB" error. The library that takes up the most space is Wordcloud (and botocore / boto3). Surely there must be a way around this? As far as I'm aware, paying for a higher tier of Vercel will not resolve this issue. Is there any workaround to this issue, or is the best option to just use a different service other than Vercel? This is my requirements.txt: Django==4.2.8 psycopg2-binary==2.9.8 Pillow==8.2.0 django-storages==1.14.2 boto3==1.34.4 botocore==1.34.4 Pyrebase4==4.7.1 regex==2020.11.13 python-dateutil==2.8.2 textblob==0.17.1 nltk==3.6.3 json5==0.9.14 jsonpath-ng==1.5.3 jsonpointer==2.4 jsonschema==4.19.0 jsonschema-specifications==2023.7.1 wordcloud==1.9.2 matplotlib==3.7.2 matplotlib-inline==0.1.6 Obviously when I remove the libraries from my project that takes up the most space, it does build successfully. So the problem is not with my code itself, and it does build and start up successfully when I open a local instance. I'm still relatively new with Python, so I would appreciate any help, even if it is "basic" - … -
hello I’ve got big problem when I open my site I’ve got “SyntaxError at / invalid syntax (views.py, line 78)” for review
It does not tell me which of my views has this problem. It is strange that there is no problem in http://127.0.0.1:8000/, but there is a problem in the host I bought.

How to make an ajax jquery request to get data from a Django ListView?
I have a base template in which I have a header and in that header, there are some link buttons that I would like to change the appearance of when clicked, for this it would be necessary to use ajax to avoid reloading the page. The request must be a GET to display the updated page data. That is, the ajax script must be done in my base.html at the button click event, to load the template that extends the base. Right? The view: class HomeListView(ListView): model = Cars template_name = 'cars.html' context_object_name = 'cars' def get_queryset(self): cars = super().get_queryset().order_by('model') return cars The data in the template cars.html (which extends base.html) is processed in this way: <div class="car-grid"> {% if cars %} {% for car in cars %} <div class="car-card"> <img src="{{ car.photo.url }}" alt="{{ car.model }} - {{ car.brand }}"> <h2> {{ car.brand }} {{ car.model }} </h2> <p> {{ car.factory_year }} - $ {{ car.value }} </p> </div> {% endfor %} {% else %} <p class="no-results">No results found. </p> {% endif %} </div> What is the smartest way to make this ajax request to get the updated cars context variable? Is there any way to pass it to … -
How to create a Django queryset based on values of recursive ManyToManyField?
I have a dictionary app where words (Lemma) can be optionally composed of other words. In my models.py, this looks like: cf = models.CharField(max_length=200) #citation form pos = models.ForeignKey(Pos, on_delete=models.CASCADE) #part of speech components = models.ManyToManyField("self", symmetrical=False, blank=True) #component Lemma I want to return two query sets: All compound verbs: Lemma that have values in self.components and where self.pos.term="verb" All unique components of compound verbs that are nouns: Lemmas that are values of some other Lemma's self.component_set() and which themselves have self.pos.term="noun". I want to use views to pass these two lists to a template. I'm able to get queryset 1 pretty easily, but my solutions for queryset 2 are all quite convoluted. The relevant class in my views.py looks like this: model = Lemma queryset = Lemma.objects.filter( Q(pos__term="verb") & ~Q(components=None) ).order_by("cf") #queryset 1, compound verbs def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) nouns = self.queryset.values_list("components") nouns = set([Lemma.objects.get(pk=l[0]) for l in nouns]) nouns= [l for l in nouns if l.pos.term == "noun"] context["nouns"] = nouns #queryset 2, nouns that are components of compound verbs return context This also leaves me with a regular list for my verbs variable rather than a proper queryset where I can use the .order_by() method … -

How can I assign a url to a button that redirect users to an external website when the data is split up into two data frames?
I have function in my view that fetches data from multiple spreadsheets and normalizes said data into one single data frame via Pandas. This df1 is eventually rendered and displayed in a webapp in the form of a bootstrap table using Django. For the sake of simplicity, let’s say this table has two columns: “Games” and “Link”. “Games" shows all the soccer matches for today and “link” simply has a button for each of the games. This button does nothing for now. Now, I have another function that fetches data from a different source and again, normalizes the data using Pandas creating a df2 with three columns: “Games”: shows some soccer matches for today (this column has some but not all the games in df1 with exactly the same format). “Id”: a 4-digit identifier that is unique to each of the games above. “Url”: a url that contains the “id” and redirects the user to an external website that provides the user with extra information about that particular match. I’m trying to figure out a way where the users can click on the buttons available in the webapp (which are linked to the games in df1) and get redirected to … -
Django display DateFormat as dd/mm/yyyy
I have a form in Django where the user needs to select the date. When the user selects the date the date is displayed in the following format mm/dd/yyyy (eg. 02/29/2024). I want the date in the form to be displayed as dd/mm/yyyy (eg. 29/02/2024 ). This is the date field in my form: date = forms.DateField( widget=forms.DateInput(format='%d/%m/%Y', attrs={'type': 'date', 'min': str(timezone.now().date()), 'max': str((timezone.now() + timedelta(days=365)).date())}), help_text='Select a date', input_formats=['%d/%m/%Y'], validators=[validate_future_date], ) I also tried: In settings.py: DATE_INPUT_FORMATS = ('%d-%m-%Y',) USE_I18N = True USE_L10N = True In the form: input_formats=settings.DATE_INPUT_FORMATS, After both of these approaches the format was still displayed as dd/mm/yyyy. -
Django View to return template with refreshed modal window
I'm using Django form in modal window where core content (in container) generated by JS. On submit django model instance saved without any issues if form.is_valid() == True a modal window closes with switching focus on current background page. However if form.is_valid() == False the modal content just opens in separate URL instead and takes all browser screen as View renders just a short code fragment in .html file. The goal is to refresh the modal window on current condition in case if form_is_valid() == False with form errors. Template "accounts/profile_settings.html" contains a form and submit button which renders inside <div class="preferences_content"> {% comment %} JS generated dynamic content depends on tab pressed. {% endcomment %} </div> My JS knowldge is very basic so I appreciate any suggestion on this topic. The View : def profile_update_view(request): """ Updates current Profile instance.""" if request.method == "POST": current_profile = request.user.profile profile_form = ProfileUpdateForm(request.POST, request.FILES, instance=current_profile) if profile_form.is_valid(): profile_form.save() return HttpResponseRedirect(request.META.get('HTTP_REFERER', "/")) else: profile_form = ProfileUpdateForm() return render(request, "accounts/profile_settings.html", {'profile_form': profile_form}) else: profile_form = ProfileUpdateForm() return render(request, "accounts/profile_settings.html", {'profile_form': profile_form}) document.addEventListener("DOMContentLoaded", function() { var openModalLink = document.getElementById("openPreferencesModal"); var modal = document.getElementById("preferencesModal"); var span = modal.querySelector(".close"); var preferencesContent = modal.querySelector(".preferences_content"); var tabs = modal.querySelectorAll(".tab"); … -
Django losing session state?
I have a VPS running apache. Apache is serving two domains, my homepage (django, django-cms, zinnia) and a prod site (django, oscar). I use falkon browser. When I change the items in site's admin (I change values in a row, it's list_editable, and then click Save), sometimes (quite often), the response returned is a redirect to login, as if the session cookie is not passed. What is interesting, if I save the POST request as curl and retry it, it succeeds. Since there are several redirects after I hit save, I've seen it failing on the first one (so the item is not saved), or the second one (the item is therefore saved, but I find myself not on the list page, but on the main admin page). How do I debug it? I suspect it may be a browser issue, I'll try mitmproxy now to see what's really hitting the network. But maybe someone has seen this behaviour before. -

Django mocking a function in a View does not work
Ok so here is the situation. I'm using Django, DRF and for tests django.test and unitest.mock I have a View which executes a method inside a post request sending a message to Kafka (send_message_to_kafka). This method is not in a viewset and I am trying to mock it. I wrote 2 tests. to call a method wrapper_send_message_to_kafka() which calls send_message_to_kafka inside it. self.client.post("/viewset/", data=payload). Both of these tests mocks the function send_message_to_kafka bypassing the actual publish to Kafka. @mock.patch('utils.send_message_to_kafka', return_value={"success": True, "message": "Message sent to Kafka successfully!"}) But the first works as expected and the second is not mocked. View @api_view(["POST"]) def example_view(request): if request.method == "POST": ... result = send_message_to_kafka(json.dumps((message))) Tests from django.test import TestCase import unittest.mock as mock ... @mock.patch('utils.pubsub.send_message_to_kafka', return_value={"success": True, "message": "Message sent to Kafka successfully!"}) def test_send_message_to_kafka(self, send_message_mock): result = wrapper_send_message_to_kafka() self.assertTrue(result["success"]) @mock.patch('utils.send_message_to_kafka', return_value={"success": True, "message": "Message sent to Kafka successfully!"}) def test_start_run(self, send_message_mock): response = self.client.post( "/execute/", data=payload, format="json", ) -
Django Register View not Saving User Model to Database

Parsing nested JSON in Django Rest Framework
I am trying to serialize a geometry dict which also contains a location dict and map that dictionaries values to my model. The data comes in two levels deep and is mapped to a single model, because its from an external API. How I've done it so far is with source='*' but this requires a new ModelSerializer for every nested object. Is there a way to "skip" to the nested object I want? For example here is some input data: { ... geometry: { location: { lat: ..., lng: ..., } } ... } Then I map it to a model like this: class MyModel(models.Model): ...other attributes from 1 level deep latitude = CharField() longitude = CharField() And my current serializer do that like this: class GeometrySerializer(serializers.ModelSerializer): latitude = serializers.DecimalField(max_digits=globals.MAX_DECIMAL_DIGITS, decimal_places=globals.MAX_DECIMAL_PLACES) longitude = serializers.DecimalField(max_digits=globals.MAX_DECIMAL_DIGITS, decimal_places=globals.MAX_DECIMAL_PLACES) class Meta: model = models.Location fields = ['latitude', 'longitude'] class GeometryLocationSerializer(serializers.ModelSerializer): location = GeometrySerializer(source='*') class Meta: model = models.Location fields = ['location'] class LocationSerializer(serializers.ModelSerializer): # Nested obj from json req, geometry: { location: { lat: ..., lng: ...} ....} #latitude = serializers.DecimalField(max_digits=globals.MAX_DECIMAL_DIGITS, decimal_places=globals.MAX_DECIMAL_PLACES, source='geometry.location.lat') #longitude = serializers.DecimalField(max_digits=globals.MAX_DECIMAL_DIGITS, decimal_places=globals.MAX_DECIMAL_PLACES, source='geometry.location.lng') geometry = GeometryLocationSerializer(source='*') class Meta: model = models.Location fields = ['id', 'addr_address', 'business_status', 'formatted_address', 'formatted_phone_number', 'icon', … -

I have gotten the error 'Operational Error: No Such Table main_enroll' In Django, and I do not understand why as I have defined it properly: Main/Models.py: from django.contrib.auth.models import AbstractUser from django.conf import settings from django.db import models class Course(models.Model): course_name = models.CharField(max_length=30) course_slug = models.CharField(max_length=70) # Other course-related fields def __str__(self): return self.course_name class Enroll(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) course = models.ForeignKey('main.Course', on_delete=models.CASCADE) Accounts/Models.py: from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): pass Screenshot of error: Copy & Paste view of error: Environment: Request Method: POST Request URL: http://127.0.0.1:8000/account/me/ Django Version: 5.0.2 Python Version: 3.11.5 Installed Applications: ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_extensions', 'main', 'welcome', 'userprofile', 'accounts'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware'] Traceback (most recent call last): File "C:\Users\shaur\BrainBall\Website\venv\Lib\site-packages\django\db\backends\utils.py", line 105, in _execute return self.cursor.execute(sql, params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\shaur\BrainBall\Website\venv\Lib\site-packages\django\db\backends\sqlite3\base.py", line 329, in execute return super().execute(query, params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The above exception (no such table: main_enroll) was the direct cause of the following exception: File "C:\Users\shaur\BrainBall\Website\venv\Lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) ^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\shaur\BrainBall\Website\venv\Lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = … -

Incoming file from post is "fakepath"
Brand new to react. My file is sending as a fakepath. I know this is for browser sercurity but I expected it to be different in my view. When I deserialize the request.body with json.loads I get this FileNotFound error. fitz.FileNotFoundError: no such file: 'C:\fakepath\HW 3 CPSC 332.pdf' When I deserialize the body with my own serializer it returns that the object is not valid.
