dBizobj:
- changed a single cursor reference to a list of cursors, keyed on parent
key. For independent cursors, this key is simply None.
- modified all methods to support this new cursor design.
- created read-only property 'Cursor' which will return the current cursor.
- removed getRowNumber(), setRowNumber() and getRowCount() methods. Replaced
them with the properties RowNumber? and RowCount?.
- removed temp PK generation and management. Moved that logic to the cursor
class.
- there is now isChanged(), which only tests the current row, and
isAnyChanged(), which tests the entire recordset.
- save(), cancel(), etc., no longer accept an 'allrows' parameter. Instead,
there are new saveAll(), cancelAll(), etc. methods to be called.
- added scan() function which takes a function that will be called once for
each record in the current recordset.
- added setChildLinkFilter() method, which tells the child bizobjs which
cursor to use as their current cursor when the parent record changes.
- added getChangedRecordNumbers(), which will return a list containing the
record numbers of all records for which isChanged() returns True. Since the
change might be in a related child record, a record number may appear in the
list even though none of its fields have changed.
- added getRecordStatus(), which accepts a record number as a parameter
(default=current record). Will return a dictionary containing an element for
each modified field. The field name will be the element key, and the element
value will be a tuple whose zeroth element is the original value, and whose
first element is its current value.
dCursorMixin:
- temp PK support is now handled here instead of the bizobj.
- getPK() will return the temp PK for a new, unsaved record
- implemented getRecordStatus() - see bizobj notes above.
- fixed bug introduced into the SQL update statements wwhen datetime support was
added.
dSqlBuilderMixin:
- added childFilterClause, to handle auto-filtering of child record sets by
the parent FK.
dForm:
- removed references to 'allrows' in save(), cancel(), etc., and replaced
them with the appropriate methods (saveAll(), etc.)
dConstants:
- added constant for the temp PK field name
