Django invalid literal for int() with base 10:

Question

I want to import data from a csv file to a model. So I have this code which does the job for me:

Import.py

import csv
with open('usuarios.csv') as f:
    reader = csv.reader(f)
    for row in reader:
        created = Users.objects.create(
                    field1=row[0],
                    field2=row[1],
                    field3=row[2],
                    )

And my model:

class Users(AbstractBaseUser):
    field1 = models.CharField(max_length=100, null=True)
    field2 = models.CharField(max_length=100, null=True)
    field3 = models.CharField(max_length=100, null=True)

But for some reason, when I execute import.ty the console handles this:

  File "<console>", line 1, in <module>
  File "<string>", line 25, in <module>
  File "C:\Python34\lib\site-packages\django\db\models\manager.py", line 154, in

    value = obj.prepare(lookup_type, value)

    return self.field.get_prep_lookup(lookup_type, value)

 1079, in get_prep_value
    return int(value)
ValueError: invalid literal for int() with base 10: '(3482) 453874'

Ideas ? I've been reading that it could have something to be with the primary_key, but I dont know what exactly

Try this:

import csv
with open('usuarios.csv') as f:
    reader = csv.reader(f)
    for row in reader:
        kwargs = {field1=row[0],
                  field2=row[1],
                  field3=row[2],}
        created = Users(**kwargs)
        created.save()
