How to not include an empty string in the icontains condition in model filter?-CodePudding

I'm currently developing an application using Django.

If I use the filter of the model and set the target of icontains to the empty string ″ as shown below, all the data is gotten.

queryset = MyModel.objects.filter(my_field__icontains='').all()

But I don't want to include it in the data if the icontains target is an empty string.

How can I enable it only if it does not include the empty string and contains other values?

Python: 3.7.5

Django: 3.2.

You check the target:

if target:
    queryset = MyModel.objects.filter(my_field__icontains=target)
else:
    queryset = MyModel.objects.none()
