Description
I use a PostgreSql database, whose table and field names contain uppercase and lowercase letters.
To refer to these fields it is necessary to place them between quotation marks (example : QSqlRelation("\"TableName\"", "\"FieldName1\"", "\"FieldName2\""))
The standard QSqlRelationDelegate does not work correctly in that case (the fields are not updated in the database).
To make it work I had to subclass QSqlRelationDelegate and add .replace("\"", "") in the setModelData() function :
def setModelData(self, editor, model, index):
if editor.metaObject().className() == "QComboBox":
if model.relationModel(index.column()) is not None:
currentItem = editor.currentIndex()
childModel = model.relationModel(index.column())
childColIndex = childModel.fieldIndex(model.relation(index.column()).displayColumn().replace("\"", ""))
childEditIndex = childModel.fieldIndex(model.relation(index.column()).indexColumn().replace("\"", ""))
model.setData(index, childModel.data(childModel.index(currentItem, childColIndex), Qt.DisplayRole), Qt.DisplayRole)
model.setData(index, childModel.data(childModel.index(currentItem, childEditIndex), Qt.EditRole), Qt.EditRole)
return
QItemDelegate.setModelData(self, editor, model, index)
