init(self, db, tablename, *fields, **args)
(Constructor)

source code

Initializes the table and performs checking on the provided fields.

Each table will have automatically an 'id'.

If a field is of type Table, the fields (excluding 'id') from that table will be used instead.

:raises SyntaxError: when a supplied field is of incorrect type.

import_from_csv_file(self, csvfile, id_map=None, null=`'<NULL>'`, unique=`'uuid'`, id_offset=None, *args, **kwargs)

source code


Import records from csv file.
Column headers must have same names as table fields.
Field 'id' is ignored.
If column names read 'table.file' the 'table.' prefix is ignored.
'unique' argument is a field which must be unique
    (typically a uuid field)
'restore' argument is default False;
    if set True will remove old values in table first.
'id_map' if set to None will not map ids.
The import will keep the id numbers in the restored table.
This assumes that there is an field of type id that
is integer and in incrementing order.
Will keep the id numbers in restored table.
