I have the following (scary) use-case: Table 'media' has 1 : N relationship to table 'history'.
class Media(object): def addHistory(self, comment): self.history.append(History(....)))Inside addHistory() I need to get hold of the mapper class History for 'history' in order to append a new items to the media's history.
Unfortunately the complete mappers are hidden behind a wrapper and the mappers are only available to the application through a dedicated getMapper() call returning a registered mapper by name. However the wrapper instance
is not available to the Media mapper itself. Is there a way to get hold of depending mapper classes - in this case the History mapper - directly from the Media mapper class (since it knows that it depends on the History mapper)? Andreas
