setting up one task per fetch. How then would one do this?

Is it possible?

SQLAlchemy and django, is it production ready? | 1,155,407 | 19 | 23 | 12,511 | 1 | python,database,django,sqlalchemy | What I would do,
Define the schema in Django orm, let it write the db via syncdb. You get the admin interface.
In view1 you need a complex join

import sqlalchemy
data = sqlalchemy.complex_join_magic(...)
...
payload = {'data': data, ...}

SQLAlchemy and django, is it production ready? | 3,555,602 | 7 | 23 | 12,511 | 1 | python,database,django,sqlalchemy | I've done it before and it's fine. Use the SQLAlchemy feature where it can read in the schema so you don't need to declare your fields twice.
You can grab the connection settings from the settings, the only problem is stuff like the different flavours of postgres driver (e.g. with psyco and without).

To be random, you must allow the random number generator to run without touching the seed. The sequence of numbers is what's random. If you change the seed, you start a new sequence. The seed values may not be very random, leading to problems.
