Question

Hi I have a problem in getting async function return value.

Directory is djangoweb/views.py
def preprocess_log2(request,uuid):
data = get_object_or_404(Adata, uuid=uuid)
if request.method == "POST":
result = log2_transform_task.delay(data.raw_path)
test = result.get()
data.mat_data = test
data.save()
return redirect("raptorlite:home")
return render(request, 'raptorlite/detail.html',{"data":data})
this is my task code
Directory is djangoweb/bin/log2_transform.py
#shared_task
def log2_transform_task(raw:str, out_dir = None) -> str:
return out_name
