您必须添加已接受的
如果未将列名添加到模型中的$fillable中，则会发生此错误

1364字段“已接受”没有默认值

此错误可能是由于数据库错误。接受的列需要可以为Null或具有如下默认值

$table->boolean('accepted')->nullable();

或

转到并将数据库数据类型中的已接受列更改为tinyint
然后按定义更改为0。。当我弄明白这一点时，它会起作用，然后可能需要
接受
，并且您不会将其传递到查询。如果您发布答案，请更精确。否则，请使用注释来进行简短的注释。
朋友的迁移文件如何将其放置在桌面上只需将布尔字段更改为：-
$table->tinyInteger（'accepted'）->默认值（0）显示错误，因为接受字段没有默认值。在您提交表单时，没有任何内容传递给accepted，因此它需要一些默认值。确认我，如果它在你的情况下工作，我会写一个详细的答案。
