Opening attribute table using PyQGIS

Question

Is it possible to open an attribute table from the Python Console or through a Python script in QGIS?

Answer 1

Yes you can, at least with the latest master version and 1.8. It is a method exposed via iface

// C++ (signature)
void showAttributeTable (QgsVectorLayer *l)
# PyQGIS (example)
iface.showAttributeTable(iface.activeLayer())

You will need a preexisting reference to a QgsVectorLayer.

For direct editing of features it is also a method exposed via iface:

// C++ (signature)
bool openFeatureForm (QgsVectorLayer *l, QgsFeature &f, bool updateFeatureOnly=false)
# PyQGIS (example)
iface.openFeatureForm(iface.activeLayer(), feature, False)

You will need a preexisting reference to a QgsVectorLayer and a QgsFeature in both cases. The feature form opened and whether it is editable are dependent upon app settings and whether the feature's layer is in edit mode.

• user25976: The Python example worked well for me when in Python console. However, I tried to run this script in Processing, where the layer = processing.getObject() of a loaded layer. From iface.showAttributeTable(layer), I got Name Error: global name 'iface' is not defined. Any suggestions?
• Mr Purple: @dakcarto You need to import iface with 'from qgis.utils import iface'
• dakcarto: @user25976 The reference to iface only works for the console or scripts run from within QGIS, including plugins like Processing. For the console, it is auto-imported for convenience, with all other cases needing the import of qgis.utils. This is described at the beginning of the PyQGIS cookbook. You can not access iface in a standalone app, since the Python modules do not instantiate the QGIS desktop GUI application.
• user99: @dakcarto iface.openFeatureForm(iface.activeLayer(), feature, False) This is useful when we want to edit the selected feature but if i want to add a new feature how can i do that? without feature
