Naming of columns

Discussed in https://github.com/piccolo-orm/piccolo/discussions/206

Allow Table columns to map to database columns with different names.

For example:

class MyTable(Table):
    name = Varchar(name="person_name")

In the example above, when doing queries, you will use MyTable.name, but the actual column in the database is called person_name.

This is useful when using Piccolo on legacy databases with non-ideal column names.

Just installed the new version. Works perfectly. Thnx.

There’s also this approach for anyone coming across this in the future:

https://github.com/piccolo-orm/piccolo/blob/69389132d5946ea29f98a763d015afe49fbc5b86/piccolo/table.py#L955

So it’s:

from piccolo.table import create_table_class

LoraKey = create_table_class(
    class_kwargs={'tablename': 'copy_lora_key', 'db': DB},
    class_members={'class': Varchar(null=False, length=1)}
)

A bit harder to read, but useful in a pinch.
