我创建了一个新的SQL web2py数据库，如下所述...但是当我尝试保存它时，它会出现语法错误。如何将其保存在web2py上并将其用于我的网页..

欢迎任何帮助...... 附：只是一个初学者..

Answer 1

首先，表名和字段名必须是有效的Python标识符，因此它们不能包含空格。相反，如果使用下划线，它们将自动转换为SQLFORM标签中的空格。您还可以为Field()构造函数指定单独的“label”参数，以便在不喜欢默认标签时为表单和网格创建标签。

其次，字段类型应该是小写的，并且没有“varchar”字段类型 - 而应该是“string”（尽管“string”是默认值，因此不是必需的）。

最后，SQLDB已被弃用，而DAL已被弃用，SQLField已被弃用，转而使用Field。

我强烈建议您在继续之前阅读DAL documentation。
