Mapping¶
Model.IO.Mapping allows to link a Model instance by a Model
namesapce and str key. this key is an external ID
Save an instance with a key:
Blok = self.registry.System.Blok
blok = Blok.query().filter(Blok.name == 'anyblok-core').first()
self.registry.IO.Mapping.set('External ID', blok)
Warning
By default if you save another instance with the same key and the same
model, an IOMapingSetException will be raised. Il really you want
this mapping you must call the set method with the named argument
raiseifexist=False:
self.registry.IO.Mapping.set('External ID', blok, raiseifexist=False)
Get an entry in the mapping:
blok2 = self.registry.IO.Mapping.get('Model.System.Blok', 'External ID')
assert blok2 is blok
