        "operate_type" => $faker->randomElement([0, 1, 2]),
        "status" => $faker->randomElement([0, 1, 2]),
        "operator" => $faker->username,
        "sort" => $faker->unique()->randomDigit,
    ];
});

public function run()
{
    // create tabs and save them to the database
    $tabs = factory(App\Models\Tab::class,8)->create();
}
    

what result do you expect? What is the error message actually seen?

some field data that is expected to be generated is not duplicated, but the current result is

with duplicate data.

say something stupid. No, no, no.

define a fake data literal array aTextContent, and then the interface method adds a list length parameter listLength, such as a list length of 10, inserting the number of 0 to 9 into a new array aRandom, to disrupt the insertion order.

returns for (int itemo when false data is returned; I < listLength; iPP) .aTextContent [aRandom [I]] (pseudo code)


. I think the plug-in has nothing to say about bug,. I changed create to make, and then changed it back, so I got better again for no reason.
