获取dynamic_data_entry
只需要一个参数(给定0)的错误。我不知道怎么修理,也不知道出了什么问题。这是一个带有GUI的BMI的代码,我想把用户的输入连同日期一起写入数据库。我无法将输入的数据写入数据库。在
**函数是类的方法 ***更新以添加整个类
我想我已经找到你的错误了。在
将作为命令的函数传递给您的
Button
类,方法如下:但是,如果方法本身需要一个隐式参数,即
self
,则直接传递该方法,这将导致得到Error
。在这个
self
表示类的对象。但是当您直接传递方法时,就不涉及对象了。在因此,您应该这样做:
^{pr2}$这样,就告诉
Button
类从对象调用方法,在本例中,self
参数将存在,因为实例化的对象存在。在确保您理解}之间的区别
