Django App running on Google Cloud Run fails SignatureDoesNotMatch with SignedUrl Storage upload
I am creating signed_urls using a Django app running on Cloud Run. def get_signed_url_for_upload(path): blob = settings.STORAGE.bucket.blob(path) expiration_time = timezone.now() + timedelta(minutes=120) signed_url = blob.generate_signed_url(expiration_time) return signed_url I am trying to use the SignedURL created with a Curl command : curl -X PUT --upload-file /Users/utku/Desktop/cat.mp4 "https://storage.googleapis.com/development-videoo-storage/d340a0e21c6b4681a1c26a46a6c30fee?Expires=1654985178&GoogleAccessId=videoo-348016%40appspot.gserviceaccount.com&Signature=delh%2BHVpqzaYl%2BGb%2FndhJbY5d7RtI4RH4q12BTd1NJoK9iU6%2BlE%2FrWAaBvdxgarafKIRH0PFpFfsFvYa4%2BauehUwaOWaY46e93fl3Cdok6Q%2BklVjQLrdAMS%2BT38YTDPdSTp1BGJir2UfsCFmjTJR7eul29y%2BjxrSZtAgUHc6%2Fym7%2FAjLuOheeKZauJAk1LmLejxPt8%2FsKm3jgHxtdAmq45OFZKVvCuYXmNghSBDTBPHOND%2BSmOyC1OXMOCFBjwgNGKziypf2OJpdQWe4iV4z9r2Afa9HYE5uHMB67ahBRip03LVCZApSnAZM7OaJrQaCPWk9pDQLaUu2rZYG49%2B9HA%3D%3D" Here is below the output that I get from curl command : <?xml version='1.0' encoding='UTF-8'?><Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided.

Variables only receive if in debug mode (Django).. WHY?
I have the following assignments to do in my code: else: form = SourceForm(request.POST) form.instance.Id = x form.instance.Sheet_name = Sheet_name form.instance.User = User_ #form.instance.Project = proj.set() form.instance.Person = p form.instance.Role_type = Function_ form.instance.Institution = inst form.instance.Survey = surv if form.is_valid(): form.save() However, if I'm in debug mode running line by line, all variables receives values correctly. But if I'm running normally it seems it doesn't perform the assignments, just the first two: form = SourceForm(request.POST) form.instance.Id = x I've never seen this before. Why do variables only receive values in debug mode? I'm using PyCharm and Django Framework -
Celery tasks not running in docker-compose
I have a docker-compose where there are three components: app, celery, and redis. These are implemented in DjangoRest. I have seen this question several times on stackoverflow and have tried all the solutions listed. However, the celery task is not running.

How to ensure only one entry is True in a Django model?
I'm stuck on thinking about implementing a "only one entry might be True for one combination". A Project has n members (Guards) through an intermediate table. every Guard may be member of n Projects only one combination of Guard <-> Project is allowed (unique_together) a MemberShip might be the 'Main' one (is_main) BUT: Only one of the memberships may be Main. Do I oversee something or do I have to implement a custom validation on my own? To complete this, see the given Model: class Project(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE) shortname = models.CharField(_('shortname'), max_length=50) description = models.TextField(_('description'), blank=True) members = models.ManyToManyField(Guard, through='ProjectMembership') class Meta: unique_together = ['client', 'shortname'] class ProjectMembership(models.Model): guard = models.ForeignKey(Guard, on_delete=models.CASCADE) project = models.ForeignKey(Project, on_delete=models.CASCADE) is_main = models.BooleanField(_('is main project'), default=False) class Meta: unique_together = ['guard', 'project'] -
Boost Django Queryset with NumPy and Numba
Please I need your help! I have a large Query set (20 million rows) at views.py and for each row I want to compare the author's value with an input value added by "author_value_input". The comparison is made in the def levenshteinDistance method. My problem is that it takes too long to complete. I tried numpy without success. Could you tell me the changes I need to make to make it more effective? Can I use Numpa jit and if so how?

Using self.object in CreateView to create objects in other tables
When a user makes a new listing using a CreateView, I am trying to use this new object to create a Bid in the Bids table. class ListingCreateView(CreateView): model = Listing fields = ['title', 'description', 'starting_bid', 'url'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def post(self, request, *args: Any, **kwargs: Any): self.object = self.get_object() starting_bid = self.request.POST['starting_bid'] Bids.objects.create(bid_value=starting_bid, bidder=self.request.user, item=self.object) return super().post(request, *args, **kwargs) But it returns the error Generic detail view ListingCreateView must be called with either an object pk or a slug in the URLconf. The docs say that "When using CreateView you have access to self.object, which is the object being created. If the object hasn’t been created yet, the value will be None." When using a CreateView, when would self.object contain the object being created? How would I work with the object that has just been created in a CreateView? -
Is there a way to have just one function in views and then put a lot of categories in it with just one path in URL?

How to get a Django form to save every time (not just the first time it's submitted)?
I am trying to make an e-commerce site (CS50 Project 2) that allows its users to save bids on different listings through a Django form. The bid should only save if it is equal to or greater than the listing price or greater than all other bids. The code was previously working, but now the form only saves the first time it is submitted. How do I get it to save every time if it meets the requirements? views.py def listing(request, id): #gets listing listing = get_object_or_404(Listings.objects, pk=id) listing_price = listing.bid sellar = listing.user bid_form = BidsForm() #code for the bid form bid_obj = Bids.objects.filter(listing=listing) other_bids = bid_obj.all() max_bid =0 for bid in other_bids: if listing.bid > max_bid: max_bid = listing.bid if request.method == "POST": bid_form = BidsForm(request.POST) if bid_form.is_valid(): new_bid = bid_form.cleaned_data.get("bid") if (new_bid >= listing_price) and (new_bid > max_bid): bid = bid_form.save(commit=False) bid.listing = listing bid.user = request.user bid.save() else: return render(request, "auctions/listing.html",{ "auction_listing": listing, "form": comment_form, "comments": comment_obj, "bidForm": bid_form, "bids": bid_obj, "message": "Your bid needs to be equal or greater than the listing price and greater than any other bids." }) else: return redirect('listing', id=id) return render(request, "auctions/listing.html",{ "auction_listing": listing, "bidForm": bid_form, "bids": bid_obj }) (There … -
About disabling autocomplete in UserCreationForm
I long searched the internet and this site looking for a solution but nothing work. The problem is that in any registration form I make in Django, each time a user click on a username or password field, a list of previously entered values is shown and this behaviour is not desirable. The raw fact is that, if I directly comment this line widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}), in # UserCreationForm, auth/form password1 = forms.CharField( label=_("Password"), strip=False, #widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}), help_text=password_validation.password_validators_help_text_html(), ) everything work as I want including the username. But I don't want to touch the Django UserCreationForm in auth/forms. The ideal would be subclass it, and customize it. Here what I did class CustomUserCreationForm(UserCreationForm): def __init__(self, *args, **kwargs): super(CustomUserCreationForm, self).__init__(*args, **kwargs) # prevents the form to automatically autofocus self.fields['email'].widget.attrs.pop("autofocus") self.fields['username'].widget.attrs.pop("autocomplete") #self.fields['password1'].widget.attrs.pop("autocomplete") #self.fields['password1'].widget.attrs.update({'autocomplete':'off', 'maxlength':'32'}) ... I tried it with many combinations, including with new-password, off, None, or even empty strings, everything is ignored. I repeat, the only way to not autocomplete the username and password fields is to comment the widget line in the original class, but this would be a very bad idea and, especially, it would break every time I will upgrade Django. Any other reasonable solutions? -

Django Template: Dynamic template variable inside another variable
I hope this makes sense... I am building a crypto asset list page (easy); however, in the {% for %} loop I would like to include a variable inside a variable. Showing the code will make more sense: Tempalte.html {% for crypto_asset in objects__list_cryptoAssets %} <tr role="row" class="body-row"> <td role="cell">{{ api_external_prices.bitcoin.usd }}</td> </tr> {% endfor %} So the {% for %} loop grabs all the crypto assets and then I can use Django template {{ asset_class.slug }} to grab all slugs... nothing exceptional here. This variable {{ api_external_prices.bitcoin.usd }} grabs external USD prices for Bitcoin, {{ api_external_prices.bitcoin.eur }} prices in EUR, and so forth... nothing exceptional here either. Here is where the question comes :: the idea would be to have something like {{ api_external_prices.{{ asset_class.slug }}.usd }}... so each crypto would have its own price FX fetched correctly. Is it possible to have a variable inside a variable? -
Django Subquery Sum with no results returns None instead of 0
I have a Django Subquery which returns a Sum. If the subquery finds at least one result, it works fine. But, if the subquery finds no records, it returns None which then causes any other calculations using this result (I use it later in my query in an F expression) to also result in None. I am trying to Sum all non-null 'consumed' values - sometimes, they are all null and therefore there are no rows upon which to sum. I would like this to result in a 0 instead of None ... annotate(tapx=Subquery(InvTrx.objects.filter(job=OuterRef('job')).\ filter(consumed__isnull=False).\ filter(inventory__inv_type='APX').\ values('job__job').\ annotate(tot_cons=Sum('consumed', default=0)).\ values('tot_cons') )).\ ... I've tried Coalesce with and without Value(0) annotate(tot_cons=Coalesce(Sum('consumed', default=0)), 0).\ annotate(tot_cons=Coalesce(Sum('consumed', default=0)), Value(0)).\ the value of tapx (which I reuse in F expressions in another part of the query) = None if no rows are returned. If at least one row is returned, this works fine. If no rows are returned, I would like the value of tapx to be 0 instead of None so that the value of fg_total in the following annotation results in a number and not None: annotate(fg_total=F('fg') + F('tapx')) Doing this outside a subquery, I have used "or 0" to force the value … -

Django Rest Framework Tests Failing When Using PostgreSQL
I'm new to Django and I recently changed the database from SQLite to PostgreSQL (first time using postgreSQL). I updated the settings with the below: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'DB_NAME', 'USER': 'DB_USER', 'PASSWORD': 'DB_PASSWORD', 'HOST': 'localhost' } } For the user, I'm not using the default postgress user, instead I created a new user (for which there is a User account on the OS) and added a password for it. I then gave that user permission to createdb: ALTER USER username CREATEDB; I've also installed psycopg2. When using the api normally, the PostgreSQL database updates just fine and works as expected. Originally when using SQLite, all the tests used to pass too. But when I changed to PostgreSQL using the above, 2 out of 9 tests fail. These are the tests that fail. The tests that fail are all under the same class. 6 of the tests are under a different class and they all pass fine. class APIDetailTest(APITestCase): items_url = reverse('site') item_url = reverse('site-item', args = [1]) def setUp(self): # Creating an initial entry to be tested. data = { "Name": "data name", "Description": "desc", "Date": "2022-06-11", "Time": "11:00:00", "Tag": "", } self.client.post(self.items_url, data, format='json') … -

However with the Django - React setup I have not been able to establish a successful. upload yet. export const UploadVideo = async (form_data, file, signedurl, asset_uuid) => { let resultState = { state: '', data: {} }; let config = { method: 'HOST', url: signedurl, headers: { 'Content-Type': 'video/mp4', "Access-Control-Allow-Origin": "*", 'Access-Control-Allow-Methods':'GET,PUT,POST,DELETE,PATCH,OPTIONS' }, data: form_data }; await axios(config).then(function (response) { console.log(JSON.stringify(response.data)); resultState.state = 'success'; }).catch(function (error) { resultState.state = 'error'; resultState.data.message = error.message; window.toastr.error(error.message); console.log(error) }) return resultState; } export const CreateAssets = async (data, key) => { let resultState = { state: '', data: {} }; await axios.get(`https://origin/asset/create/?category=1&title=%22` + data[key].title + `%22&size=1`) .then(res => { resultState.state = 'success'; resultState.data = res.data; }).catch((err) => { resultState.state = 'error'; resultState.data['message'] = err.message; }) return resultState; } The code for react js get singed url and calling signedurl with the file dialog is available. What shall I do for a succesful signedurl file upload to Google Cloud Storage ? -
Mypy complaining about Name "Optional" is not defined without the use of Optional
I've recently started using mypy, and have run into some weird problems that i cannot for the life of me seem to figure out. I'm using mypy 0.950, django-stubs 1.11.0, django 4.0.5 and python 3.10.2.
