Re: Abridged summary of django-users@googlegroups.com - 23 updates in 11 topics

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…

Your clue is in the word "variable" that you used. The "variables" for a
Django model are its fields; so what you are looking for is a value stored
in your model's field.

One strategy might be to:
 
1) Bring in the data under a different column name ('old_id' ?)
2) In a single migration, drop the default ID column, rename old_id to id,
and give it primary_key=True ...more
