Postgresql 以奇怪形式显示的数字类型

postgresql

Postgresql 以奇怪形式显示的数字类型,postgresql,pyqt,qt-designer,Postgresql,Pyqt,Qt Designer,我正在使用PyQt+Qt设计器，并已将其连接到我的PostgreSQL数据库。当我尝试使用以下代码显示数据库中的记录时： if self.Kirurg_checkBox.isChecked(): Kirurg_query = QSqlQueryModel() Kirurg_query.setQuery("SELECT * FROM kirurg") global view

我正在使用PyQt+Qt设计器，并已将其连接到我的PostgreSQL数据库。当我尝试使用以下代码显示数据库中的记录时：

if self.Kirurg_checkBox.isChecked():
                     Kirurg_query = QSqlQueryModel()
                     Kirurg_query.setQuery("SELECT * FROM kirurg")
                     global view_Kirurg
                     view_Kirurg = QtGui.QTableView()
                     view_Kirurg.setModel(Kirurg_query)
                     view_Kirurg.setWindowTitle('kirurg')
                     view_Kirurg.show()

数字列看起来像这样：2.3177e+09，而它们应该像在我的数据库中一样，就像这样：2317698765。在我（在PostgreSQL内部）将列类型从字符（11）更改为数字（11,0）（这是我所必需的）之前，这种方法工作得很好。有没有办法让这些列以正常的方式显示值，而不是这种奇怪的方式

编辑：

我将if列==0（因为这是奇怪的值所在的位置，但也是最后一列，第4列）。它完全删除了我的第一列（第0列），修复了最后一列（第4列），因此它看起来很漂亮，并且给了我很多错误行：

并将它们聚在一起，所有这些都是一样的。

您可以使用它们来格式化数据

简短解释

在数据列索引中设置委托（在本例中为2），并将其放入

QtGui.QTableView

class QCustomDelegate (QtGui.QItemDelegate):
    def paint (self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex):
        column = indexQModelIndex.column()
        if column == 2:
            textQString = '%.0f' % indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole)
            # textQString = indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole).toString() # For some version PyQt4-4.11.1-gpl-Py3.4-Qt4.8.6-x64
            self.drawDisplay(painterQPainter, optionQStyleOptionViewItem, optionQStyleOptionViewItem.rect, textQString)
        else:
            QtGui.QItemDelegate.paint(self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex)

及

详细解释（建议阅读此）
1）首先，您需要知道列中的格式化数据是什么。这是我的数据示例

+------------+------------+-----------------+ | Name | Owner | Value | +------------+------------+-----------------+ | Sushi | Lawson | 2.3177e+12 | | Yakisoba | Lawson | 1.4141e+12 | | Snack | 7-11 | 3.1446e+12 | +------------+------------+-----------------+
好的，我想在第3列显示整数格式，而不是指数格式
2）在指定的列索引处设置格式。本例是第3列中的整数格式。此外，您还可以自定义所需的格式，如xxxx.xx$等。在本例中，将转换为字符串以便于显示整数

class QCustomDelegate (QtGui.QItemDelegate): def paint (self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex): column = indexQModelIndex.column() if column == 2: textQString = indexQModelIndex.model().data(indexQModelIndex, QtCore.Qt.EditRole).toString() self.drawDisplay(painterQPainter, optionQStyleOptionViewItem, optionQStyleOptionViewItem.rect, textQString) else: QtGui.QItemDelegate.paint(self, painterQPainter, optionQStyleOptionViewItem, indexQModelIndex)
3）将
QCustomDelegate
放到
QtGui.QTableView
或子类中的by方法。像这样,

myQTableView = QtGui.QTableView() myQTableView.setItemDelegate(QCustomDelegate())
最后，数据应该是这样的

+------------+------------+-----------------+ | Name | Owner | Value | +------------+------------+-----------------+ | Sushi | Lawson | 2317700000000 | | Yakisoba | Lawson | 1414100000000 | | Snack | 7-11 | 3144600000000 | +------------+------------+-----------------+

Meybe返回的
indexQModelIndex.model（）.data（indexQModelIndex，QtCore.Qt.EditRole）
是浮点数据类型（不是
QVariant
）。好的，把它转换成字符串。查看我的编辑帖子。我有个问题，你的PyQt版本是什么？谢谢，现在开始工作了！你是救命恩人，再一次：）。我使用的是PyQt4，这个版本：PyQt4-4.11.1-gpl-Py3.4-Qt4.8.6-x64.exe。我再问你一件事。我把if column==2，它对我所有的数字列都有效，为什么？例如，它适用于“我的ID”列（第0列）和“我的电话号码”列（第4列）？因为在标准视图中显示自定义模型中的项目。默认显示为字符串值或指数格式值。处于
QItemDelegate
的机制中。或者简单地说，我们创建自定义显示数据，默认情况下所有数据都将显示字符串格式。
