[Answer]-Need to upper all models

If what you mean by 107 variables is that there are 107 rows in the database, you can open the Django shell with:

$ python manage.py shell

and from the Python shell import your database model:

>>> from myapp.models import MyModel

and run whatever you want on it:

>>> for o in MyModel.objects.all:
...  o.nombre_contacto_15 = o.nombre_contacto_15.upper()
...  o.save()
...
>>>
