qgis - How to update the attribute table of feature using PyQGIS?

Following code updates the value of field ("name") in console and shows the result but actual attribute table does not get update .Can anybody suggest the error in code.

layer=iface.activeLayer()

selected_feature=layer.selectedFeatures()


layer.startEditing()

for feature in selected_feature:

    feature["name"]="Test name"

layer.commitChanges()

Answer

You need to update the layer with the new feature values using:

layer.updateFeature(feature)

So it should look something like:

layer = iface.activeLayer()
selected_feature = layer.selectedFeatures()
layer.startEditing()
for feature in selected_feature:
    feature["name"] = "Test name"
    layer.updateFeature(feature)


layer.commitChanges()

Or shorten it slightly by editing and commiting the changes in one go using with edit():

layer = iface.activeLayer()
selected_feature = layer.selectedFeatures()
with edit(layer):
    for feature in selected_feature:
        feature["name"] = "Test name"
        layer.updateFeature(feature)
