Nested configuration options about dacite HOT 3 CLOSED

Hi @achennu, it's possible, here you go:

from dataclasses import dataclass
from dacite import from_dict, Config

@dataclass
class A:
    x: int
    y: int

@dataclass
class B:
    a: A
    is_cool: bool

@dataclass
class C:
    b: B
    count: int

C_config = Config(remap={'count': 'number'}, prefixed={'b.a': 'a_'})

DATA={
    'number': 30,
    'b': {
        'is_cool': False,
        'a_x': 30,
        'a_y': 55,
    }
}

from_dict(data_class=C, data=DATA, config=C_config)

You have right that I should improve documentation, there is no mention of "dot" syntax (b.a) at all. Let's leave this issue as open, so I will add a few words about it in the next release.

Ah I see, so that's the idea to have deeper nested structures handled. Thanks for the quick response.

Adding to the documentation is a good idea. Maybe a separate "When you really mean nested" section, as the current examples are short and to the point.

Do I understand it correctly that this "dot syntax" can be used for an of the Config settings?

A few examples that I'm wondering (aloud) about:

Config(remap={''b.a.x": "X"}) when the data dict contains "X" instead of "x".

Config(flattened=['b.a.']) can work?

Your welcome :)

Yep.

Config(remap={''b.a.x": "X"}) when the data dict contains "X" instead of "x".

It should work like that.

Config(flattened=['b.a.']) can work?

Config(flattened=['b.a']) - without trailing dot.
