Hi.
I find the use of asc and desc functions not very flexible.
I have implemented these functions:
from sqlalchemy import sql
def orderBy(table, colum, direction):
return sql._CompoundClause(None, table.c[column], direction.upper())
def buildOrderList(table, order=[]):
return [
orderBy(table, column, direction)
for column, direction in order
]
As an example:
buildOrderList(usernames, [('username', 'asc')])
In this way I can use strings where possible.
