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:

+
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:

+
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 function obsolete.

+

A few rules must be observed:

+
    +

  • Only simple types can be processed +
    +Wrong: dict[str, str] +
    +Correct: dict +
    +
    +Incorrect: list[str] +
    +Correct: list

    • +

  • The arguments must be optional, i.e. created as kwargs +
    +Incorrect: def __init__(self, x: int, y: int) +
    +Correct: def __init__(self, x: int = None, y: int = None)
