<br>
I try to set the configuration for a vector layer with python.<br>
Below is one of the many ways I tried to do it.<br>
Now I'm of out of ideas (chatgpt, intellij ai assistent and google as <br>
well) and would be thankful for a working example.<br>
<br>
Thanks Roland<br>

Code you can use in a Python Console Editor. First it creates a layer to <br>
use for the test and then tries to set the field configuration.<br>
<br>
# =================<br>
# Setup Layer with field<br>
# =================<br>
<br>
# Create a vector layer<br>
layer = QgsVectorLayer("Point?crs=EPSG:4326", "MyLayer", "memory")<br>
if not layer.isValid():<br>
print("Failed to create the layer!")<br>
sys.exit(1)<br>
<br>
# Add fields to the layer<br>
layer_data_provider = layer.dataProvider()<br>
layer_data_provider.addAttributes([QgsField("field1", QVariant.String)])<br>
layer.updateFields()<br>
<br>
# Add a feature to the layer<br>
feature = QgsFeature(layer.fields())<br>
feature.setGeometry(QgsGeometry.fromPointXY(QgsPointXY(0, 0)))<br>
feature.setAttribute("field1", "value1")<br>
layer_data_provider.addFeature(feature)<br>
layer.updateExtents()<br>
<br>
# Add the layer to the project<br>
project = QgsProject.instance()<br>
project.addMapLayer(layer)<br>
<br>
# =================<br>
# Try to set field configuration<br>
# =================<br>
layer.startEditing()<br>
for field in layer.fields():<br>
config_flags = field.configurationFlags()<br>
config_flags |= Qgis.FieldConfigurationFlag.HideFromWfs<br>
field.setConfigurationFlags(config_flags)<br>
#layer.updateFields()<br>
layer.commitChanges()<br>
<br>
