modelx v0.7.0 (24 May 2020)¶
This release introduces some new features and fixes bugs around updating objects and values upon model changes.
UserSpace.formula setter and deleter
UserSpace.formula property now supports assignment
and deletion operations, such as:
>>> Space.formula = lambda x, y: None >>> del Space.formula
When the Formula of a UserSpace is reassigned or deleted, existing child ItemSpaces are deleted.
UserSpace.parameters property now supports assignment
operation, such as:
>>> Space.parameters = ('x', 'y=0')
The assignment to
UserSpace.parameters is a syntactic sugar
and the code above is equivalent to:
>>> Space.set_formula(lambda x, y=0: None)
Backward Incompatible Changes¶
References not being updated for reassigned Formulas.
Sub spaces directly under Model not being updated after its bases’ deletion.
Dependents values not being cleared at Cells’ deletion.
