thinkphp mode's find method fails

I encountered a strange problem today

Using the D('Custoemr')->find(1) statement, no sql is executed, which is very strange.

The find method using models from other tables works fine. Combined with the D('Custoemr')->add() method, the primary key is not returned.

I felt that the problem should be with the primary key, so I carefully checked the customer table and found that there were indeed two primary keys. One of them was clicked on by mistake.


So here’s a summary again, if there is a table with multiple primary keys, then neither the find nor create methods will execute normally
