Python TypeError unsupported operand type(s) for %: 'file' and 'unicode'

Question

I\'m working on a django field validation and I can\'t figure out why I\'m getting a type error for this section:

def clean_tid(self):
    data = self.cleaned_da         


        

Answer 1

Check your parenthesis.

Wrong

stdout_handel = os.popen("/var/www/nsmweb/jre1.6.0_14/bin/java -jar /var/www/nsmweb/sla.jar -t %s grep -v DAN")  % data

Might be right.

stdout_handel = os.popen("/var/www/nsmweb/jre1.6.0_14/bin/java -jar /var/www/nsmweb/sla.jar -t %s grep -v DAN"  % data )
