Bug: Configuration.from_yaml() cannot read properly template strings in a yaml file #857
Description
Hi, I'm using Configuration.from_yaml() to read template strings in a yaml file like below:
template_string: |- Hi! My name is ${name}. I'm ${age} years old. I'm living in ${country}.And When I read the yaml file, the variables string in the yaml file disappear.
class Container(DeclarativeContainer): config = Configuration() config.from_yaml(yaml_dir / "introduce.yaml") ... container = Container() print(container.config.template_string()) # Hi! My name is .\nI'm years old.\nI'm living in .But when I use pyyaml directly, it doesn't have any problem.
class Container(DeclarativeContainer): config = Configuration() config.from_pydantic(PydanticConfig()) # config.from_yaml(yaml_dir / "introduce.yaml") introduce_yaml_path = yaml_dir / "introduce.yaml" with open(introduce_yaml_path, "r") as f: loaded = yaml.safe_load(f) config.from_dict(loaded) print(container.config.template_string()) # Hi! My name is ${name}.\nI'm ${age} years old.\nI'm living in ${country}.Could you guys clear up what happens in from_yaml()?
Thanks!
