|

|
## ConfigurationModelABC from_dict method
|
||
|
|
|
||
|
|
We now process the configuration models directly in the configuration by recursive parameter parsing.
|
||
|
|
|
||
|
|
The JSONProcessor now goes through the JSON and the arguments of the __init__ and links the attributes by name from the
|
||
|
|
JSON and the name of the keyword argument.
|
||
|
|
Now, based on the type, either simply assigns the value. With a ``dict`` the processor is called recursively and so the
|
||
|
|
JSON is processed further. This way nested ConfigurationModels can be processed.
|
||
|
|
|
||
|
|
For this the code must be adapted as follows:
|
||
|
|
|
||
|
|
From this:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
class VersionSettings(ConfigurationModelABC):
|
||
|
|
|
||
|
|
def __init__(self):
|
||
|
|
ConfigurationModelABC.__init__(self)
|
||
|
|
|
||
|
|
self.major: Optional[str] = "0"
|
||
|
|
self.minor: Optional[str] = "0"
|
||
|
|
self.micro: Optional[str] = "0"
|
||
|
|
|
||
|
|
def from_dict(self, settings: dict):
|
||
|
|
self.major = settings["Major"]
|
||
|
|
self.minor = settings["Minor"]
|
||
|
|
micro = settings["Micro"]
|
||
|
|
if micro != '':
|
||
|
|
self.micro = micro
|
||
|
|
```
|
||
|
|
|
||
|
|
To this:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
class VersionSettings(ConfigurationModelABC):
|
||
|
|
def __init__(self, major: str = None, minor: str = None, micro: str = None):
|
||
|
|
ConfigurationModelABC.__init__(self)
|
||
|
|
|
||
|
|
self.major: Optional[str] = major
|
||
|
|
self.minor: Optional[str] = minor
|
||
|
|
self.micro: Optional[str] = micro if micro != "" else None
|
||
|
|
```
|
||
|
|
|
||
|
|
This makes the [from_dict](#from_dict) function obsolete.
|
||
|
|
|
||
|
|
A few rules must be observed:
|
||
|
|
|
||
|
|
- Only simple types can be processed
|
||
|
|
<br>
|
||
|
|
Wrong: ```dict[str, str]```
|
||
|
|
<br>
|
||
|
|
Correct: ```dict```
|
||
|
|
<br>
|
||
|
|
<br>
|
||
|
|
Incorrect: ```list[str]```
|
||
|
|
<br>
|
||
|
|
Correct: ```list```
|
||
|
|
|
||
|
|
- The arguments must be optional, i.e. created as kwargs
|
||
|
|
<br>
|
||
|
|
Incorrect: ```def __init__(self, x: int, y: int)```
|
||
|
|
<br>
|
||
|
|
Correct: ```def __init__(self, x: int = None, y: int = None)```
