Question

I installed a jeroennoten/Laravel-AdminLTE which is, Package version 2.x (Laravel 6).After installing i modify my user table, register.blade.php and registercontroller for username and role. But when i submitting the form it always give me a error default value is not set for username. Here is my view

<div class="form-group has-feedback {{ $errors->has('role') ? 'has-error' : '' }}">
                    <select name="role" class="form-control">
                        <option>Register As</option>
                        <option value="candidate">Candidate</option>
                        <option value="voter">Voter</option>
                    </select>
                    <span class="glyphicon glyphicon-role form-control-feedback"></span>
                    @if ($errors->has('role'))
                        <span class="help-block">
                            <strong>{{ $errors->first('role') }}</strong>
                        </span>
                    @endif
                </div>
 <div class="form-group has-feedback {{ $errors->has('username') ? 'has-error' : '' }}">
                    <input type="text" name="username" class="form-control" value="{{ old('username') }}"
                           >
                    <span class="glyphicon glyphicon-user form-control-feedback"></span>
                    @if ($errors->has('username'))
                        <span class="help-block">
                            <strong>{{ $errors->first('username') }}</strong>
                        </span>
                    @endif
                </div>

And my registercontroller

protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'username' => ['required', 'string'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:6', 'confirmed'],
            'role' => ['required'],
        ]);
    }

    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'username' => $data['username'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'role' => $data['role'],
        ]);
    }

Answer 1

Check your model, i think username parameter is missing.

protected $fillable = [
    'name', 'email', 'password', 'username', 'role'
];
