I am getting a "404 | Not Found" error when i try to access a specific item from my database. The items with the specific ID's do exist in the database, but i am not even sure if that even has any influence on the problem.

My routing looks likes this:

Route::prefix('departments')->group(function() {
Route::get('/{id}', [DepartmentController::class, 'showDepartment']);
});

And the related controller looks like this:

public function showDepartment() {
        return '';
    }

}

I haven't yet finished the function. I just wanted to check if the routing even worked by returning an empty string.

So what am i doing wrong? Is it the routing or the controller?

CodePudding user response：

According to the Laravel documentation, you have to define the parameter in the route then use it in the controller as a parameter. in your controller:

public function showDepartment($id) {
    return 'Hello';
}

The id is not bound to any model to fetch from the database to do that you can use Laravel route model binding

for example when you have a model named Department you write your route like this:

Route::get('/{department}', [DepartmentController::class, 'showDepartment']);

and in the controller:

public function showDepartment(Department $department) {
    return 'Hello from depratment';
}

When your department exists it returns the response otherwise return 404.

CodePudding user response：

You may need a Department model class. Then you can find the item from database by id $department = Department::findOrFail($id);

CodePudding user response：

you are send parameter in route and this function without any parameter route :

Route::prefix('departments')->group(function() {
Route::get('/{id}', [DepartmentController::class, 'showDepartment']);
});

your function in controller should be

public function showDepartment($id) {

        $department = Department::findOrFail($id);
    }

}
