python
def __new__(mcs, name: str, bases: Tuple[type], attrs: Dict[str, Any]):
fields_db_projection = {} # type: Dict[str,str]
fields_map = {} # type: Dict[str,DjangoField]
filters = {} # type: Dict[str,DjangoFilter]
admin_fieldsets = OrderedDict() # type: Dict[str,Tuple[str,str]]
order_field = None # type: str
search_fields = [] # type: List[str]
global_search = False # type: bool
geo_search = False # type: bool
I'm curious about how this dynamic creation process works within this constructor. Could you help clarify what each part of this snippet is intended to do? I'm especially puzzled about how `fields_db_projection` and `fields_map` are supposed to be used later on.
<>: Sure! Let's break down what this snippet is doing:
1. **Dynamic Class Creation**: The `__new__` method is used here for creating a new class dynamically using `type()`. This allows customization of class creation before an instance is made.
2. **Attributes Initialization**:
- `fields_db_projection`: This dictionary maps field names to their database column names. It helps in translating model field names to actual database columns.
- `fields_map`: This dictionary maps field names to their corresponding Django field objects (`DjangoField`). It’s useful for accessing field metadata.
- `filters`: Holds Django filters associated with fields.
- `admin_fieldsets`: An ordered dictionary used for defining custom fieldsets in Django admin.
- `order_field`, `search_fields`, `global_search`, `geo_search`: These variables manage ordering and search functionalities.
3. **Usage**:
- **`fields_db_projection`** is likely used when interacting with the database directly (e.g., raw SQL queries) where you need to know which database column corresponds to which model field.
- **`fields_map`** is useful when you need metadata about fields (like type or validation rules) during runtime.
These mappings allow for flexible manipulation of model fields during class creation, enabling advanced configurations like custom admin interfaces or search capabilities.
<>: Got it! Now, I want to add functionality for custom validation logic during this dynamic class creation process. I was thinking of introducing a new dictionary called `custom_validations` that would map field names to validation functions. These functions should be executed whenever the class is instantiated or when specific fields are accessed or modified. How can I integrate this into the existing setup?
<>: To integrate custom validation logic using a `custom_validations` dictionary, you can follow these steps:
1. **Add the Dictionary**: Introduce `custom_validations` in your `__new__` method.
python
custom_validations = {} # type: Dict[str, Callable[[Any], bool]]
2. **Define Validation Functions**: Each entry in `custom_validations` should map a field name to a function that takes a value and returns a boolean indicating if the value passes validation.
3. **Integrate Validation Logic**: You'll need to modify how instances are created or accessed/modified:
- **During Instance Creation**: Override methods like `__init__` or use descriptors/magic methods (`__get__`, `__set__`) within your dynamically created class to incorporate validation checks.
- **Example Integration**:
python
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
for field_name, validation_func in custom_validations.items():
value = kwargs.get(field_name)
if value is not None:
if not validation_func(value):
raise ValueError(f"Validation failed for {field_name}: {value}")
def __setattr__(self, name, value):
if name in custom_validations:
if not custom_validations[name](value):
raise ValueError(f"Validation failed for {name}: {value}")
super().__setattr__(name, value)
4. **Dynamic Class Creation**: Ensure these methods are included when creating your class dynamically.
By doing this, you ensure that any time an instance is created or specific fields are accessed/modified, your custom validations are applied automatically.
<>: Alright! So I want to make sure these validations are applied every time an instance is created or when specific fields are accessed or modified. I'm thinking of overriding methods like `__init__`, `__get__`, and `__set__` within the dynamically created class. How do I ensure these methods are properly integrated during the class creation process? Should I modify the way I'm using `type()` here?
<>: python
Yes, you'll need to modify how you're using `type()` to ensure these methods are integrated into your dynamically created class. Here’s how you can do it:
1. **Define Methods**: Create functions for `__init__`, `__get__`, and `__set__` that include your validation logic.
2. **Pass Methods via `type()`**: When using `type()` to create your class dynamically, pass these methods as part of the class attributes.
Here’s an example:
python
def __new__(mcs, name: str, bases: Tuple[type], attrs: Dict[str, Any]):
# Existing initializations...
def __init__(self, *args, **kwargs):
super(self.__class__, self).__init__(*args)
for field_name, validation_func in custom_validations.items():
value = kwargs.get(field_name)
if value is not None:
if not validation_func(value):
raise ValueError(f"Validation failed for {field_name}: {value}")
def __setattr__(self, name: str, value: Any):
if name in custom_validations:
if not custom_validations[name](value):
raise ValueError(f"Validation failed for {name}: {value}")
super(self.__class__, self).__setattr__(name, value)
def __getattribute__(self, name):
attr = super(self.__class__, self).__getattribute__(name)
if name in custom_validations:
# You might want additional logic here if needed
pass
return attr
attrs['__init__'] = __init__
attrs['__setattr__'] = __setattr__
attrs['__getattribute__'] = __getattribute__
return super().__new__(mcs, name, bases + (object,), attrs)
# Example usage
custom_validations = {
'field_name': lambda x: isinstance(x, int) and x > 0
}
MyClass = type('MyClass', (object,), {
'__module__': __name__,
})
This setup ensures that your custom validation logic is applied whenever instances are created or specific fields are accessed/modified.
<>: Great! Now I'm thinking about making these validations more efficient by caching results where possible. Also, I want them to trigger automatically when attributes change without explicitly calling setters or getters each time. How can I achieve this? Should I look into using descriptors or metaclasses differently?
<>: python
To make your validations more efficient with caching and automatic triggering upon attribute changes without explicitly calling setters/getters each time, you can indeed leverage descriptors along with metaclasses.
Here’s how you can achieve this:
1. **Use Descriptors**: Create descriptor classes that handle getting and setting attributes with validation logic.
2. **Cache Results**: Use instance-level caching within descriptors to store validated values.
Here’s an example implementation:
python
class ValidatedField:
def __init__(self, validation_func):
self.validation_func = validation_func
self.cache_name = f"_cached_{validation_func.__name__}"
def __get__(self, instance=None, owner=None):
if instance is None:
return self
return getattr(instance.__dict__, self.cache_name)
def __set__(self, instance, value):
if not self.validation_func(value):
raise ValueError(f"Validation failed for value: {value}")
setattr(instance.__dict__, self.cache_name, value)
def __new__(mcs, name: str, bases: Tuple[type], attrs: Dict[str, Any]):
# Define your validations here
validations = {
'field_name': ValidatedField(lambda x: isinstance(x, int) and x > 0),
# Add more fields as needed
}
# Add validated fields as descriptors
attrs.update(validations)
return super().__new__(mcs, name, bases + (object,), attrs)
# Example usage
MyClassMeta = type('MyClassMeta', (type,), {
})
MyClass = MyClassMeta('MyClass', (object,), {
})
# Usage example
obj = MyClass()
obj.field_name = 10 # Passes validation
print(obj.field_name) # Cached result
try:
obj.field_name = -5 # Fails validation
except ValueError as e:
print(e)
### Key Points:
- **Descriptors**: They automatically handle getting/setting attributes with built-in caching.
- **Metaclass Integration**: Use metaclasses (`MyClassMeta`) to integrate these descriptors into your class definition.
- **Efficiency**: Caching validated values reduces redundant checks.
This approach ensures efficient validation with automatic triggering upon attribute changes.
<>: Awesome! Now I'm considering adding conditional logic within these validations based on other attributes' states or external conditions. For instance, if one field meets certain criteria before another can be validated correctly. How can I implement this kind of interdependent validation within the descriptors?
<>: python
To implement interdependent validation within descriptors based on other attributes' states or external conditions, you can enhance your descriptor logic by accessing other attributes during validation.
Here’s how you can achieve this:
1. **Access Other Attributes**: Within your descriptor’s `__set__` method, access other attributes of the instance.
2. **Conditional Logic**: Implement conditional checks based on these attributes.
Here’s an example:
python
class InterdependentField:
def __init__(self, validation_func):
self.validation_func = validation_func
self.cache_name = f"_cached_{validation_func.__name__}"
