Hi Your date settings seem to only affect dates when they are being rendered.
When a date is input and later pushed into the database - a date like 02/03/2013 is ambiguous as the database cannot determine whether you mean 2nd Mar or 3rd Feb; dates like 02/26/2013 are not ambiguous. So you get what seems like inconsistent behaviour. You probably need to perform some format checking AFTER the form has been posted. You can then use your date formatting switch to control the change. There are several possible ways of doing this: e.g. create a function to perform the conversion and call this from a clean method in forms.py as part of the form validation https://docs.djangoproject.com/en/1.5/ref/forms/validation/ An alternative approach would be to provide a js date picker like the one used in the admin interface for date fields On Fri, 5 Jul 2013 03:43:34 -0700 (PDT) Sivaram R <sivaram2...@gmail.com> wrote: > All > > 1.My application consist of two part.Part I -
