Question

models.py

def operation(argument):
            #Operation
    return variable

    class X(models.Model)
        a = models ...
        b = models ...

I am trying to import operation in my views.py .. When I try using

from project.models import operation

But then I get the following error

ImportError: cannot import name operation

Answer 1

/* */ aren’t valid comment characters in python, which is causes a parse error, so the import fails. Use # instead.

Also, you’ll want to get an instance of X then call the operation method on that. Like:

from myproj.models import X
x = X.objects.get(id=1)
val = x.operation()
