Hello All,
On Django admin when I tried to update the existing data I’m getting an error,
AttributeError: 'str' object has no attribute '__iter__'
models.py
class SSPDrive(models.Model):
drive_year =
models.DateField(verbose_name='Drive year', null=True, blank=True,
help_text="Enter drive year.")
class Meta:
verbose_name = "SSP Drive"
verbose_name_plural = "SSP Drives"
def __str__(self):
return
str('SSP'+str(self.drive_year.year)[-2:]+'T'+str(self.drive_year.year+1)[-2:])
class SSPDriveAdmin(admin.ModelAdmin):
save_as = True
class Meta:
model = SSPDrive
admin.site.register(SSPDrive, SSPDriveAdmin)
Can someone help me out, why am I getting this error…
