Hey guys,
I feel really dumb and I guess I am missing some basic concept...:
* I have a layer with two attributes: "text" (string) and "int" (integer).
* I used drag'n'drop form design to have a form with just the "text"
attribute in it.
* I added Python Init Code:
```
from functools import partial
def on_ok(layer, feature):
field_idx = layer.fields().indexOf("int")
attribute_changed = layer.changeAttributeValue(feature.id(),
field_idx, 12345)
if not attribute_changed:
raise Exception("Attribute value could not be changed!")
def my_form_open(dialog, layer, feature):
ok_button = dialog.findChild(QPushButton)
ok_button.clicked.connect(partial(on_ok, layer, feature))
```
So the form does not show an input widget for the "int" field. But when
pressing OK, the code should change the edited feature's "int" value to
12345.
This works if I edit existing features.
But if I create a new feature, the "int" value will be empty/NULL
instead of 12345.
Any pointers on how to properly update a new feature's attribute fields,
that exist on a layer but are not shown the user with the QGIS' widgets
in the attribute form?
Cheers, Hannes
