There is no problem with the associated model, but I can’t get it when I get the uri from the database. I could still get it normally yesterday, but I can’t get it today
replyThank you, sir. After debugging like crazy for a long time, I discovered that the intermediate tables in the database had been cleared. The problem has been solved!

Break point, give it a try, look at the data structure, find one, there is no need for foreach,
