Class: QgsFeatureFilterModel¶
- class qgis.core.QgsFeatureFilterModel¶
Bases:
QgsFeaturePickerModelBaseProvides a list of features based on filter conditions. Features are fetched asynchronously.
New in version 3.0.
QgsFeatureFilterModel(parent: QObject = None) Create a new
QgsFeatureFilterModel, optionally specifying aparent.Methods

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL
types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.
- Parameters:
name (str = ...) –
revision (int = ...) –
arguments (Sequence = ...) –
- Return type:
PYQT_SIGNAL
- identifierField(self) str¶
The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer. If there are several identifier fields defined, the behavior is not guaranteed
Deprecated since version QGIS: 3.10 use identifierFields instead
- Return type:
str
- identifierFields(self) List[str]¶
The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer.
New in version 3.10.
- Return type:
List[str]

Allows specifying one value that does not need to match the filter criteria but will still be available in the model as NULL value(s).
New in version 3.10.
- setExtraIdentifierValueUnguarded()¶
- setExtraIdentifierValues(self, extraIdentifierValues: Iterable[Any])¶
Allows specifying one value that does not need to match the filter criteria but will still be available in the model.
New in version 3.10.
- Parameters:
extraIdentifierValues (Iterable[Any]) –
- setIdentifierFields(self, identifierFields: Iterable[str])¶
The identifier field should be a unique field that can be used to identify individual features. It is normally set to the primary key of the layer.
Note
This will also reset identifier fields to NULL
New in version 3.10.
- Parameters:
identifierFields (Iterable[str]) –
