Field_name in actions

[qgib]

Author Name: Alessandro Perego (Alessandro Perego)
Original Redmine Issue: 22120
Affected QGIS version: 3.4.8
Redmine category:actions

---

(tested on QGIS 3.4.8 on Windows 10)

Actions in field scope have three variables: field_index, field_name, field_value.
Field_name doesn’t work when actions run from attribute table.

For example the following python action (in field scope):

from qgis.PyQt import QtWidgets
expr = '"[% @field_name %]"' + ' = ' + "'[% @field_value %]'"
QtWidgets.QMessageBox.information(None, "[% @field_name %]", expr)

works good from Identify Result panel, but when the action run from the attribute table it doesn’t show the name of the field.

A workaround is using the field index:
layer = QgsProject.instance().mapLayer('[% @layer_id %]')
field_name = layer.fields().field([% @field_index %]).name()
