Hi Mr. Akumbo, The options for Model Fields that come with django in the django.db library and are listed and explained here: https://docs.djangoproject.com/en/dev/ref/models/fields/#model-field-types
Each corresponds to a different type of data. For example name = models.CharField(max_length=60) just means that the the database will store a 60-character text string (VARCHAR). Other libraries can define other field types. For example, the https://pypi.python.org/pypi/django-localflavor package has Model fields specific to different nations such as localflavor.za.forms.ZAPostCodeField for South African postal codes. If you really need to, you can look at the source code <https://github.com/django/django-localflavor/blob/0dac2721293e9ece827c74ab11aa0255b8062d69/localflavor/za/forms.py> of that project for an example of defining your own. It sounds like you are working through someone else's django project but would find some broader context useful. If you haven't already, I would recommend working through the tutorial, starting here: https://docs.djangoproject.com/en/dev/intro/tutorial01/ best regards, Andrew Farrell On Mon, Jun 2, 2014 at 8:51 PM, ngangsia akumbo <ngang...@gmail.com> wrote: > > > On Sunday, June 1, 2014 7:42:13 PM UTC+1, Thomas wrote: > >> >> On 2014-05-31, at 4:41 AM, ngangsia akumbo <ngan...@gmail.com> wrote: >> >> please i need some legit answer please >> >> >> Please give one or two specific examples of functionality you need.
