Did they have the same ID(pk)??

Arsen, how can I access that id?

It is impossible that two rows have the same ID They can have the same values if there is no unique fields I suppose u just have the same values in db

Hi guys. I'm newbie and I have a little question. I was iterating sql_queries variable in my template and noticed the same query printed twice. Did Django really made 2 identical queries or it somehow cached the result of the first query and then used it in the second case? I have a screenshot, but I can't post it here, sorry

It is not the cache

How to fix 502 error in response?? In django rest framework

How to fix 502 error in response?? In django rest framework

502 it’s related to web server, you need to check your apache/nginx config files

It’s bad gateway

But without using filter in it .. it's working fine

I need filter also here

Oh sorry I thought you wore in production already

Please send the code snippet that is causing the problem

Yes it's in error come in production only

Okay

def post(self, request): try: controller = CustomerListController(data=request.data) paginator = Paginator(controller.get_data(),25) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) data = [] for p in page_obj: data.append(p) return Response(data,status=status.HTTP_200_OK) # return Response(status=status.HTTP_200_OK, data=controller.get_data()) except Exception as e: # print(e) return Response({"message": "Internal Server Error","error":str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)

Please send the code snippet that is causing the problem

Please check once

except Exception as e: # print(e) return Response({"message": "Internal Server Error","error":str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) if you are getting an error is because on the try block there is something wrong paginator = Paginator(controller.get_data(),25) maybe here, I'm not sure

You can't use "/" operation for paths concatenation if your BASE_DIR is a string Instead, your BASE_DIR should be an instance of pathlib.Path For example: from pathlib import Path SETTINGS_DIR = Path(__file__).resolve().parent.parent BASE_DIR = SETTINGS_DIR.parent print(BASE_DIR / "db.sqlite3") # Valid now

that's more a JS thing, not Django —directly—

Don't ask meta questions like: "Any user of $x here?" "Anyone used technology $y?" "Hello, I need help on $z!" Just ask directly! The better you are at explaining the problem, the more likely you are to get help. Asking smart questions

I already change max_length to under 20 but still error like this

but the error is saying that the value you want to save is longer than 20... why did you change you field to store it lower than 20? it doesn't make sense

Hello. I have a problem in Django. image = ProductImages.objects.get(product_id=id, main_or_not=True) The image url should come here, but the image name comes up. I can't understand what the problem is. Please help if anyone knows.

Hello. I have a problem in Django. image = ProductImages.objects.get(product_id=id, main_or_not=True) The image url should come here, but the image name comes up. I can't understand what the problem is. Please help if anyone knows.

what is the name of the URL field?

image.<field_name>.url can work in this case

Alex image

Try image.image.url

i tried but it didn't work

This way data-img="{{ image.image.url }}"

Have you configured static and media URL?

yes

print(image.image.url) It shows url but not working in template

print(image.image.url) It shows url but not working in template

Check if the URL is loaded in the frontend via inspect elements

Also, check if the image appear on following the URL

Other elements appear on the frontend. And 127.0.0.1:8000/media/media/products/banner10.jpg shows the image

Then something in the frontend is wrong.

I got it. thank you so much for your help )

Hi Guys, I have this function to calculate the sum of a column in my model, but when I apply a filter on the admin page the sum keeps the total column sum and not the column filtered, hoe should I proceed? def total(self): total = Batch.objects.aggregate(Sum('amount_company')) return round(total["amount_company__sum"], 2)

batches = Batch.objects.filter(...) total = batches.aggregate(...) Will solve it

batches = Batch.objects.filter(...) total = batches.aggregate(...) Will solve it

Stefan, I dont got how should I do.

hello everyone

Stefan, I dont got how should I do.

First, filter your queryset then aggregate that filter. So first line (batches = Batch.objects.filter(you_filter_here) will filter your query and the second line will apply aggregation of that filter.

Good morning Please how knows where I can get a detailed explanation on how to integrate paystack or Django futterwave on django
