我们是否需要在迁移文件中完成验证规则中的unique（）？

Question

I have already specified a column to be unique in my migration file. Do I need to do it again in validation rule?

Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->string('imageName')->unique();

Answer 1

You need to write a validation rule to get the error message, otherwise, whenever you will be adding two files with the same name it'll throw an exception ...
