Laravel Union操作后排序错误的问题 Fix the wrong order after using union method in Laravel query

解决方法,在两个子查询中分别加上limit即可。可以使用较大的数确保所有记录返回。

The solution is to use the limit method on the two subqueries. You can use a larger number to ensure that all records are returned.

 

Laravel 5.5在浏览器中预览Notification渲染 Previewing Laravel Notification In Browser

对于Mail,我们可以通过下面的代码在浏览器中预览Mailables

For Mail, we can preview Mailables in the browser with the following code.

然而Notification类中toMail返回的MailMessage实例,Laravel文档中并没有给出直接方法在浏览器中预览,我们可以采取下面的方法。

However, the MailMessage instance returned by toMail method in the Notification class does not give a direct method to preview in the browser in the Laravel document. We can use the following code.

在Laravel5.8及以上,MailMessage实现了Renderable接口(PR in Github),所以可以直接return MailMessage实例作为响应了。

In Laravel 5.8 and above, MailMessage implements the Renderable interface (PR in Github), so you can directly return the MailMessage instance as a response.
