web2py SQLFORM.grid url

当我尝试将form=SQLFORM.grid（db.mytable）放入控制器时，请求更改为my/web/site/view？_signature=520af19b1095db04dda2f1b6cbea3a03c3551e13，这会导致控制器中的if语句崩溃。smbd能否解释为什么会发生这种情况

如果我将user_signature=False，则在视图加载时会显示网格（尽管外观很糟糕，我仍然需要了解如何更改我的表的视图），但在搜索、编辑等操作时，再次出现相同的情况。url已更改，我收到一个错误

有什么建议吗

多谢各位

更不用说sqlgrid看起来很糟糕，下面是图片的链接

如果您显示

if

语句，我们可以找出如何更正它。签名是出于安全目的而存在的，因此URL不能被操纵。请澄清您的期望和正在发生的情况（例如，您是否遇到异常？）。您的

if

语句检查request.args[0]的值，因此用户签名将不受影响（因为它存储在request.get\u vars中）。此外，URL看起来不像my/web/site/view？\u签名=。。。相反，它将类似于/yourapp/default/edit/view/worker/1？\u signature=。。。（最后，请在上面的代码中添加换行符，这样我们就不必水平滚动。）另外，为什么要将

.as_list

方法应用于

行

对象，而不是使用正常的

行

功能来访问记录和字段？关于网格的外观，您是否使用带有默认CSS的脚手架应用程序，您能否确认CSS文件已加载到该页面上？如果没有，您将需要应用自己的CSS样式。
