Python 使用QSqlTableModel在QTreeView上存储期间处理更改的行
我有一个Python 使用QSqlTableModel在QTreeView上存储期间处理更改的行,python,sqlite,pyqt,qsqltablemodel,Python,Sqlite,Pyqt,Qsqltablemodel,我有一个QTreeView，它通过QSqlTableModel（PyQt5版本：5.13.0）显示来自SQLite的结果。 我想通过详细信息对话框更改一些值，该对话框通过modelTable.record（）填充数据。 因此，我将编辑策略设置为OnManualSubmit，然后使用submitAll（）存储值 问题：我使用record.setValue（）将更改后的值写入Db。 但是：如果我更改一个值两次，它的当前行号可能会更改 复制： 运行下面的代码 双击最后一行，名称为“a”的单元格；将名称
QTreeViewQSqlTableModelmodelTable.record（）OnManualSubmitsubmitAll（）record.setValue（）唯一约束失败：也会发生无法获取行的情况
期望值：第二次按“保存”时，对话框中的值显示在最后一行，第1行中的旧值是正确的
（如果在两次修改操作之间按下“刷新”btn或关闭dlg，您将得到此信息。）
