知道模型是否包含数据 [英] Know Whether Model Contain Data or Not

问题描述

HELLO Friends，
我的情况是我的控制器在我看来有些数据，否则可能无法通过.

现在我想知道我的模型是否有数据.

实际上，我详细地告诉您，我正在使用视图中的表格显示数据.
问题是如果我的控制器没有返回表，则不应显示该表，而是显示该模型是否具有数据.
所以我想检查模型是否有数据，以便可以将其放入

IF()


请给我解决方案

推荐答案

不完全知道您的意思，但是通过检查您的模型对象是否为空，您应该能够确定它是否为空.

Don''t know exactly what you mean but by check if your model object is null, you should be able to find out whether it is created or not.

请重新输入文字，很难看到您的具体要求.

Please reword, difficult to see what you are asking for specifically.
