Hi, When changing the model, you will need to migrate. Rather update the past_date field with the newdate etc..

So as the day passes , passed date field have to be removed and new date after 59 days from today has to be added.

I am curious, what are you trying to achieve that necessitates adding and removing fields? And wouldnt that be solved better with some table relationship instead?

So in models.py file there's one field which is to be removed and another field is to be added at the end. This process has to be done once daily at specific time. For example, assume there are five fields in my models i.e. A,B,C,D and E. At some specific time field B will be removed and new field E will be added after D, again same process will repeat next day field C will be removed and new field F will be added after E. I can implement this process through python file handling and "with" method. So my question is, should i implement this process in my Django project? Will this process work efficiently in production environment? -- You received this message because you are subscribed to the Google Groups "Django users" group.
