Downloading a file from Django template on click doesn't work
I tried multiple ways to download a file on click from a Django template, but the download just won't start. Here's my view where I get the file path: def success(request): model_file_path = request.session.get('model_file_path') if request.method == 'POST': return render(request, "success.html", {'filepath': model_file_path}) else: return render(request, "success.html", {'filepath': model_file_path}) And here is what I tried in the success template with no success: <a href='{{filepath}}' download>download</a> <a href='{{ MEDIA_URL }}{{filepath}}' download={{filepath}}>download</a> <a href='{{filepath}}' download={{filepath}}>download</a> It just won't trigger a download, although the path is correct. -
Updating Database via GET request to Generic views in Django
I've got this Generic view that would list records from my DB for GET request to localhost:8000 However, I also want to UPDATE those records upon GET. For instance, GET localhost:8000 would return a list like so: [ { "user": 1, "address": "sdfgasgasdfg", "balance": "123.00000000" }, { "user": 1, "address": "sdfgasgasdfg25", "balance": "123.00000000" } ] Upon GET, I would like to also make an API to https://www.blockchain.com/api/blockchain_api to get the latest BTC balance and update the balance values for those addresses in my DB. Not quite sure how to do so with generic views view class WalletListCreateAPIView(generics.ListCreateAPIView): queryset = Wallet.objects.all() serializer_class = WalletSerializer model class Wallet(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) address = models.CharField(max_length=34) balance = models.DecimalField(max_digits=16, decimal_places=8) slug = models.SlugField(max_length=34, blank=True, null=True) def __str__(self): return self.address def save(self, *args, **kwargs): self.slug = slugify(self.address) super().save(*args, **kwargs) -
Generate data when button/link is clicked Django

Django Loop Through Objects After Bulk .update()
This code runs on cron. So I want to update the status of the objects immediately so that these objects don't get picked up again if a second cron starts before the current one finishes (which will eventually start to happen with my app.) # Grab all pending emails. emails = delivery_que.objects.filter(status='PENDING') emails.update(status='SENDING') # Loop through the pending emails. for email in emails: The current code doesn't work, as I seem to no longer have access to the objects after I .update() them. This is the workaround I implemented: # Grab all pending emails. emails = delivery_que.objects.filter(status='PENDING') emails.update(status='SENDING') emails = delivery_que.objects.filter(status='SENDING') # Loop through the pending emails. for email in emails: Is there another better solution I'm missing?
