Question

我正在使用QtableView来显示和编辑来自QsqlTableModel的数据。一切都很好：显示来自postgreSQL表的数据，用户可以编辑它并保存修改。

我想在点击按钮时添加一行。我使用QslTableModel中的insertRecord方法。该行已在QTableView中正确添加。

我的问题是：我想在此新行的第一个单元格中插入查询中的值。（自动填充唯一标识符）。

这是我的代码：

该值未插入新行（但如果我手动输入值，则效果很好）。不过，查询还可以（我可以看到«print identifiant»行，它会返回预期的整数）。

你看到我做错了吗？

是否还有其他方法可以在QTableView单元格中以编程方式插入值？

或者我必须使用QitemDelegate吗？

感谢您提前。

最后我找到了解决方案：

此行创建一条记录，但不是我的QsqlTableModel

的记录

    record = QtSql.QSqlRecord()

我用这个替换它，它完美地运作：

    record = self.model.record()
