Thanks for the reply. I am new to python and django. Will have to
google a lot to understand your solution :-)
Look at models.ForeignKey ...
https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey
When you add a foreign key field to a table, the Django Admin form
offers a choice of all the values from the table you specify.
If you are writing your own forms this might help ...
https://stackoverflow.com/questions/5104277/field-choices-as-queryset
A custom command just needs to follow a specific pattern and contain
functions with specific names so the command can be executed like python
manage.py fetch_web_values

I have an outside python function which reads a csv from web

that tuple in my python models for choices in one of the

copying the returned tuple to my models.py for choices. But
there must be some better way. like pickling it etc etc. Can
anyone help me with that?
I suggest you import the csv data into a table using a manage.py
custom command. Then you need to point your field requiring
choices at that table.
You could perhaps then run your manage.py command on a cron schedule?
