Bases: Model

Stopwatch Model

Note

The stopwatch model is not a regular interface and instead is dynamically generated on Access through the Card .stopwatch attribute. There is an override that intercepts __getitem__ to return a Stopwatch.

All Stopwatch methods directly update the .stopwatch attribute of the linked Card instance.

ATTRIBUTE	DESCRIPTION
startedAt	The start date of the stopwatch TYPE: datetime
total	The total time of the stopwatch (in seconds) TYPE: int
_card	The card the stopwatch is associated with (Managed by the Card class) TYPE: Card

Returned by:

• Plankapy v1 Card Interfaces Card
  •  add_stopwatch
  •  remove_stopwatch

Used by:

• Plankapy v1
  • Card Interfaces Card  update
  • Board Interfaces List  create_card
  • Models  Card_

__eq__	Check if two model instances are equal
__getitem__	Get the value of an attribute

__eq__

__eq__(other: Model) -> bool

Check if two model instances are equal

Note

Compares the hash and class of the model instances

Warning

Does not compare the attributes of the model instances, out of sync models with different attributes can still be equal, it's best to refresh the models before comparing.

PARAMETER	DESCRIPTION
other	The other model instance to compare TYPE: Model

RETURNS	DESCRIPTION
bool	True if the model instances are equal, False otherwise TYPE: bool

__getitem__

__getitem__(key) -> Any

Get the value of an attribute

Warning

This is an implementation detail that allows for the unpacking operations in the rest of the codebase, all model attributes are still directly accessible through __getattribute___

Note

Returns None if the attribute is Unset or starts with an underscore

Example

print(model['name'])
>>> "Model Name"

model.name = Unset
print(model['name'])
>>> None

    return val if val is not Unset else None

__hash__

__hash__() -> int

Generate a hash for the model instance so it can be used in mappings (dict, set)

Note

All Models are still mutable, but their ID value is unique

RETURNS	DESCRIPTION
int	The hash value of the model instance TYPE: int

Example

board_map = {
    Board(name="Board 1"): board.,
    Board(name="Board 2"): "Board 2"
}
>>> 1

        return int(self.id)

    # Default hash if no id (string of name and attributes)
    return hash(f"{self.__class__.__name__}{self.__dict__}")

__iter__

__iter__()

Iterate over public, assigned model attribute names

Warning

This is used in conjunction with __getitem__ to unpack assigned values. This allows model state to be passed as keyword arguments to functions

Example:

model = Model(name="Model Name", position=1, other=Unset)

def func(name=None, position=None):
    return {"name": name, "position": position}

print(func(**model))
>>> {'name': 'Model Name', 'position': 1}

Notice how only the assigned values are returned after unpacking and any Unset or private attributes are skipped, This allows None values to be assigned during a PATCH request to delete data

Note

Skips attributes that are Unset or start with an underscore

RETURNS	DESCRIPTION
Iterator	The iterator of the model attributes

Example

# Skip Private attributes
print(list(model.__dict__))
>>> ['_privateattribute', 'name', 'position', 'id']

print(list(model))
>>> ['name', 'position', 'id'] # Skips _privateattribute

# Skip Unset attributes
print(model.___dict___)
>>> {'_privateattribute': 'Private', 'name': 'Model Name', 'position': Unset, 'id': 1}

items = dict(model.items())
print(items)
>>> {'name': 'Model Name', 'id': 1} # Skips position because it's Unset
