cubicweb #509108 reflexivity of relationships [open]
if a relation R is reflexive, it can link an object to itself. For example, same_value_as is reflexive, but child_of is not, event though both relations can link two objects of the same type A. Non-reflexivity can currently be expressed with a constraint, but passing a parameter to the constructor or setting an attribute to True/False would be better. | |
