usercode.py isn't a real module, but an example of a module produced by gencode.py from the
|
|
user-defined document schema.
|
|
|
|
It is the same code that's produced from the test schema in test_gencode.py. In fact, it is used
|
|
as part of that test.
|
|
|
|
User-defined Tables (i.e. classes that derive from grist.Table) automatically get some additional
|
|
members:
|
|
|
|
Record - a class derived from grist.Record, with a property for each table column.
|
|
RecordSet - a class derived from grist.Record, with a property for each table column.
|
|
RecordSet.Record - a reference to the Record class above
