django save error

问题

for *** :
   try:
       xx = A(
          a=x,
          b=y
       )
       xx.save()
   except:
     pass

here is my question: once one of the "xx" saved error, others will not save success. Does any one know why? thanks!

here is the error message

Exception

回答1:

You catch every exception with this statement:

except:
   pass

GeneratorExit is just an exception. This should not be caught. Please catch only the exceptions, you expect.

回答2:

You shouldn't catch GeneratorExit. If you want to catch all exceptions inherited from Exception rather then from BaseException you should change your code for:

for *** :
   try:
       xx = A(
          a=x,
          b=y
       )
       xx.save()
   except Exception:
     pass
