Usage

@view_config(route_name='data', renderer='json')
def data(request):
    """Return server side data."""
    # defining columns
    #  - explicitly cast date to string, so string searching the date
    #    will search a date formatted equal to how it is presented
    #    in the table
    columns = [
        ColumnDT(User.id),
        ColumnDT(User.name),
        ColumnDT(Address.description),
        ColumnDT(func.strftime('%d-%m-%Y', User.birthday)),
        ColumnDT(User.age)
    ]

    # defining the initial query depending on your purpose
    #  - don't include any columns
    #  - if you need a join, also include a 'select_from'
    query = DBSession.query().\
        select_from(User).\
        join(Address).\
        filter(Address.id > 4)

    # instantiating a DataTable for the query and table needed
    rowTable = DataTables(request.GET, query, columns)

    # returns what is needed by DataTable
    return rowTable.output_result()
