I have this function in my Django REST API that handles the insertion of products. Sometimes a product will be a variational product (when product.type = 3), in which case I get all the permutations of these variations and want to insert a new product corresponding to each permutation into the database.
@api_view(['POST'])
def upsertProduct(request):
productData = request.data['product']
variations = productData.pop('variations', [])
variationTypes = productData.pop('variationTypes', [])
product, created = Product.objects.update_or_create(pk=productData['id'], defaults=productData)
if (productData['type'].id == 3):
variations_by_type = []
for variationType in variationTypes:
variations_by_type.append([variation for variation in variations if variation['variationType'] == variationType['id']])
combinations = list(itertools.product(*variations_by_type))
for combination in combinations:
productData['name'] = product.name + ' (' + ' | '.join(' : '.join(i['name'] for i in item) for item in combination) + ')'
productData['type'] = {'id': 5}
productData['parent'] = product.id
#Recursive call should go here
#upsertProduct(request={'data': {'product': productData}})
My first attempt was to simply call the function as I did in the commented line. Django returned the following
AssertionError: The request argument must be an instance of
django.http.HttpRequest, not builtins.dict.
I then attempted making use of this HttpRequest object from Django, but can not figure out how to use it properly for this use case. I've also tried the standard request library in Python, without success, and I am also pretty sure that wouldn't be an ideal solution even if it did work.
