Helping Snippets - Add attributes to your SQLAlchemy model from a dictionary
I wanted to add all attributes from a dictionary to my model, the only problem is, the dictionary has to have the exact same keys as the model. In my case the dictionary has more keys, so I ran into errors when using
This is why I created a small function I placed inside my model class, to handle that problem for me:
class MyModel: ... def add_attributes_from_dict(self, attribute_list: dict) -> None: model_attribute_list = self.__mapper__.attrs.keys() for key, value in attribute_list.items(): if key in model_attribute_list: setattr(self, key, value)
This will only add the attributes if they are present inside the model.
