django save error

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

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.

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
