>>> ln.save(ln.ULabel.from_values(["ULabel1", "ULabel2", "ULabel3"], field="name")) # noqa >>> labels = ln.ULabel.filter(name__icontains = "label").all() >>> ln.ULabel(name="ULabel1").save() >>> label = ln.ULabel.filter(name="ULabel1").one() >>> label.parents.set(labels) >>> manager = label.parents >>> manager.df()
Attributes
- auto_created bool¶
- creation_counter int¶
- db property¶
- use_in_migrations bool¶
If set to True the manager will be serialized into migrations and will thus be available in e.g. RunPython operations.

**kwargs
, seelamindb.core.QuerySet.df()
.
- df(**kwargs)¶
Convert to DataFrame.

- list(field=None)¶
Populate a list with the results.
Examples
>>> ln.save(ln.ULabel.from_values(["ULabel1", "ULabel2", "ULabel3"], field="name")) >>> labels = ln.ULabel.filter(name__icontains="label").all() >>> ln.ULabel(name="ULabel1").save() >>> label = ln.ULabel.filter(name="ULabel1").one() >>> label.parents.set(labels) >>> label.parents.list() >>> label.parents.list("name") ['ULabel1', 'ULabel2', 'ULabel3']
- lookup(field=None, **kwargs)¶
