akkudoktoreos.prediction.predictionabc.PredictionContainer

class akkudoktoreos.prediction.predictionabc.PredictionContainer(*args: ~typing.Any, providers: ~typing.List[~akkudoktoreos.prediction.predictionabc.PredictionProvider] = <factory>)

Bases: PredictionStartEndKeepMixin, DataContainer

A container for managing multiple PredictionProvider instances.

This class enables access to data from multiple prediction providers, supporting retrieval and aggregation of their data as Pandas Series objects. It acts as a dictionary-like structure where each key represents a specific data field, and the value is a Pandas Series containing combined data from all PredictionProvider instances for that key.

Note

Derived classes have to provide their own providers field with correct provider type set.

__init__(*args: Any, **kwargs: Any) → None

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

providers: List[PredictionProvider]

__copy__() → Self: Returns a shallow copy of the model.

__deepcopy__(memo: dict[int, Any] | None = None) → Self: Returns a deep copy of the model.

__delitem__(key: str) → None

Set the value of the specified key in the data records of each provider to None.

Parameters:: key (str) – The field name in DataRecords to clear.
Raises:: KeyError – If the key is not found in any provider.

classmethod __get_pydantic_core_schema__(source: type[BaseModel], handler: GetCoreSchemaHandler, /) → CoreSchema

Hook into generating the model’s CoreSchema.

Parameters:

source – The class we are generating a schema for. This will generally be the same as the cls argument if this is a classmethod.
handler – A callable that calls into Pydantic’s internal CoreSchema generation logic.

Returns:

A pydantic-core CoreSchema.

classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) → JsonSchemaValue

Hook into generating the model’s JSON schema.

Parameters:

core_schema – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.
handler – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.

Returns:

A JSON schema, as a Python object.

__getitem__(key: str) → Series

Retrieve a Pandas Series for a specified key from the data in each DataProvider.

Iterates through providers to find and return the first available Series for the specified key.

Parameters:: key (str) – The field name to retrieve, representing a data attribute in DataRecords.
Returns:: A Pandas Series containing aggregated data for the specified key.
Return type:: pd.Series
Raises:: KeyError – If no provider contains data for the specified key.

__init__(*args: Any, **kwargs: Any) → None

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

__iter__() → Iterator[str]

Return an iterator over all unique keys available across providers.

Returns:: An iterator over the unique keys from all providers.
Return type:: Iterator[str]

__len__() → int

static __new__(cls: Type[SingletonMixin], *args: Any, **kwargs: Any) → SingletonMixin

Creates or returns the singleton instance of the class.

Ensures thread-safe instance creation by locking during the first instantiation.

Parameters:

*args – Positional arguments for instance creation (ignored if instance exists).

SingletonMixin

__pretty__(fmt: Callable[[Any], Any], **kwargs: Any) → Generator[Any, None, None]: Used by devtools (https://python-devtools.helpmanual.io/) to pretty print objects.

classmethod __pydantic_init_subclass__(**kwargs: Any) → None

This is intended to behave just like __init_subclass__, but is called by ModelMetaclass only after the class is actually fully initialized. In particular, attributes like model_fields will be present when this is called.

This is necessary because __init_subclass__ will always be called by type.__new__, and it would require a prohibitively large refactor to the ModelMetaclass to ensure that type.__new__ was called in such a manner that the class would already be sufficiently initialized.

This will receive the same kwargs that would be passed to the standard __init_subclass__, namely, any kwargs passed to the class definition that aren’t used internally by pydantic.

Parameters:: **kwargs – Any keyword arguments passed to the class definition that aren’t used internally by pydantic.

__setitem__(key: str, value: Series) → None

Add or merge a Pandas Series for a specified key into the records of an appropriate provider.

Attempts to update or insert the provided Series data in each provider. If no provider supports the specified key, an error is raised.

Parameters:

property record_keys: list[str]: Returns the keys of all fields in the data records of all enabled providers.

property record_keys_writable: list[str]: Returns the keys of all fields in the data records that are writable of all enabled providers.

classmethod reset_instance() → None: Resets the singleton instance, forcing it to be recreated on next access.

reset_to_defaults() → PydanticBaseModel: Resets the fields to their default values.

classmethod schema(by_alias: bool = True, ref_template: str = '#/$defs/{model}') → Dict[str, Any]

classmethod schema_json(*, by_alias: bool = True, ref_template: str = '#/$defs/{model}', **dumps_kwargs: Any) → str

set_nested_value(path: str, value: Any) → None

Set a nested value in the model using a ‘/’-separated path.

Supports modifying nested attributes and list indices while preserving Pydantic validation. Automatically initializes missing Optional, Union, dict, and list fields if necessary. If a missing field cannot be initialized, raises an exception.

Parameters:

path (str) – A ‘/’-separated path to the nested attribute (e.g., “key1/key2/0”).
value (Any) – The new value to set.

Raises:

KeyError – If a key is not found in the model.
IndexError – If a list index is out of bounds or invalid.
ValueError – If a validation error occurs.
TypeError – If a missing field cannot be initialized.

Example

```python class Address(PydanticBaseModel):

city: Optional[str]

class User(PydanticBaseModel):: name: str address: Optional[Address] settings: Optional[Dict[str, Any]]

user = User(name=”Alice”, address=None, settings=None) user.set_nested_value(“address/city”, “Los Angeles”) user.set_nested_value(“settings/theme”, “dark”)

print(user.address.city) # Output: “Los Angeles” print(user.settings) # Output: {‘theme’: ‘dark’} ```

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

property start_datetime: DateTime | None

Returns the start datetime of the current or latest energy management.

Returns:: The starting datetime of the current or latest energy management, or None.
Return type:: DateTime

to_dict() → dict

Convert this PredictionRecord instance to a dictionary representation.

Returns:

A dictionary where the keys are the field names of the PydanticBaseModel,: and the values are the corresponding field values.

Return type:

dict

to_json() → str

Convert the PydanticBaseModel instance to a JSON string.

Returns:: The JSON representation of the instance.
Return type:: str

property total_hours: int | None

Compute the hours from start_datetime to end_datetime.

Returns:: The duration hours, or None if either datetime is unavailable.
Return type:: Optional[pendulum.period]

update([E, ]**F) → None. Update D from mapping/iterable E and F.: If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

update_data(force_enable: bool | None = False, force_update: bool | None = False) → None

Update data.

Parameters:

force_enable (bool, optional) – If True, forces the update even if a provider is disabled.
force_update (bool, optional) – If True, forces the providers to update the data even if still cached.

classmethod update_forward_refs(**localns: Any) → None

classmethod validate(value: Any) → Self

classmethod validate_and_convert_pendulum(value: Any, info: ValidationInfo) → Any

Validator to convert fields of type pendulum.DateTime.

Converts fields to proper pendulum.DateTime objects, ensuring correct input types.

This method is invoked for every field before the field value is set. If the field’s type is pendulum.DateTime, it tries to convert string or timestamp values to pendulum.DateTime objects. If the value cannot be converted, a validation error is raised.

Parameters:

value – The value to be assigned to the field.
info – Validation information for the field.

Returns:

The converted value, if successful.

Raises:

ValidationError – If the value cannot be converted to pendulum.DateTime.
