OccasionCollection

Abstract base class for generic types.

class activity.collections.occasion.OccasionCollection(session: sqlalchemy.orm.Session, **kwargs: Any)

Bases: onegov.core.collection.GenericCollection[onegov.activity.models.Occasion]

Abstract base class for generic types.

A generic type is typically declared by inheriting from this class parameterized with one or more type variables. For example, a generic mapping type might be defined as:

class Mapping(Generic[KT, VT]):
    def __getitem__(self, key: KT) -> VT:
        ...
    # Etc.

This class can then be used as follows:

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT:
    try:
        return mapping[key]
    except KeyError:
        return default

property model_class: type[onegov.activity.models.Occasion]

static to_half_open_interval(lower: int, upper: int) → onegov.activity.types.BoundedIntegerRange

Postgres coerces ranges internally to be half-open in an effort to canonize these ranges. This function does the same by taking a closed interval and turning it into a half-open interval of the NumericRange type.

add(activity: onegov.activity.models.Activity, period: onegov.activity.models.Period, start: datetime.datetime, end: datetime.datetime, timezone: str, meeting_point: str | None = None, age: Sequence[int] | None = None, spots: Sequence[int] | None = None, note: str | None = None, cost: decimal.Decimal = Decimal(0), exclude_from_overlap_check: bool = False) → onegov.activity.models.Occasion

add_date(occasion: onegov.activity.models.Occasion, start: datetime.datetime, end: datetime.datetime, timezone: str) → onegov.activity.models.OccasionDate
