Searching in multiple models' tables in Django Rest Framework

Question

I have 3 tables

• PC(ID, PcNAME, Brand)
• CellPhoness(ID, CellPhoneName, Brand)
• Printers(ID, PrinterName, Brand) .

There is no relationship between the 3 tables. I would like to run a query where the user can input the search string and the program will search the 3 models for where the data exists and return the same with the Id, name, and brand in the form of a JSON response.

Answer 1

You can do something like this:

1. Get query text from query params

2. Filter based on it

3. Return serializer data

    def view(request): query = request.GET.get("query", None) pcs = PC.objects.all() cell_phones = CellPhone.objects.all() printers = Printer.objects.all() if query: pcs = pcs.filter(name__icontains=query) cell_phones = cell_phones.filter(name__icontains=query) printers = printers.filter(name__icontains=query) return JsonResponse({"pcs": PCSerializer(instances=pcs, many=True).data, "cell_phones": CellPhoneSerializer(instances=cell_phones, many=True).data, "printers": PrinterSerializer(instances=printers, many=True).data})

You'll need to create serializers for each objects, please have a look at this documentation .
