“提交”按钮，在出现的灰色，而不是绿色的我使用Php Storm。任何可以帮助我什么是问题。在此先感谢

Answer 1

添加

{{ csrf_field() }} 

当你使用一个正常的形式不是集合HTML。在模型中，你必须通过你输入的名称fileden

// pass all the name in your form in your case just name 
protected $fillable = ['name']; 

，或者您可以使用

protected $guarded // here you pass what is not going to add 

Answer 2

你应该CSRF令牌字段添加到您的形式，以防止令牌匹配异常：

使用这个帮手您的形式：

{{ csrf_field() }} 

或

<input type="hidden" name="_token" value="{{ csrf_token() }}"> 

而且你提交按钮的类是btn-primary，这不是绿色的！

Answer 3

至于说关于“MassAssignmentException”，这意味着你尝试添加新的数据，但没有准备正确的属性$可填写

protected $fillable = ['name', ....]; 

https://laravel.com/docs/5.4/eloquent#mass-assignment

你也可以使用$ guared财产，只是为了保护你的数据。

protected $guarded = ['price'];
