Potential desync in model configuration at the model.py level

[irm-codebase]

What happened?

Calliope v0.7 keeps most of its attributes within model._model_data.attrs[] in the form of dictionaries.

However, model math and config are replicated in model.math and model.config. This introduces potential sync issues, necessitating some helper functions to keep these up-to-date. This is done via the _add_observed_dict() and _add_model_data_methods().

But this requires careful use of these functions in several parts of the code, and is a bit inefficient (we essentially duplicate the same model property).

Which operating systems have you used?

As a proposal, I believe we should extend our use of @properties to standardize access to math and config.

I think this should do the trick:

@property
    def name(self):
        return self._model_data.attrs["name"]

    @name.setter
    def name(self, value: str):
        self._model_data.attrs["name"] = value

    @property
    def inputs(self):
        return self._model_data.filter_by_attrs(is_result=0)

    @property
    def results(self):
        return self._model_data.filter_by_attrs(is_result=1)

    @property
    def math(self):
        value = self.self._model_data.attrs["math"]
        if not isinstance(value, AttrDict):
            value = AttrDict(value)
        return value

    @math.setter
    def math(self, value: dict):
        if not isinstance(value, dict):
            raise TypeError(
                f"Attempted to add dictionary math to model, but received argument of type `{type(value).__name__}`"
            )
        self._model_data.attrs["math"] = AttrDict(value)

    @math.deleter
    def math(self):
        del self._model_data.attrs["math"]

    @property
    def config(self):
        value = self._model_data.attrs["config"]
        if not isinstance(value, AttrDict):
            value = AttrDict(value)
        return value

    @config.setter
    def config(self, value: dict):
        if not isinstance(value, dict):
            raise TypeError(
                f"Attempted to add configuration to model, but received argument of type `{type(value).__name__}`"
            )
        self._model_data.attrs["config"] = value

    @config.deleter
    def config(self):
        del self._model_data.attrs["config"]

    @property
    def is_built(self):
        return self._is_built

    @property
    def is_solved(self):
        return self._is_solved
