When users visit the homepage, they will be routed to the registration page register.htm by default. The attribute instruction ensure-unique is defined in register.htm, but the instruction in directive.js is not bound and does not work. I don’t know. What is the reason? There is no error reported in the front end. Please help to check

It has been solved, the module without instructions is injected into the module of myApp
Hello moderator, how did you solve your problem? Why did you write a module? Isn’t it enough to just put a module in app.js?
