自建model，save时报错：array_key_exists(): ......

删掉一个 应该可以的

@isMi 那就不晓得了 代码没有看到有问题

哦哦，删掉还是报错

@chowjiawei 好吧，谢谢哈

sex有默认值吗

dd下你的user为1的模型，看看里面是什么

@chowjiawei 有默认值0

@chowjiawei我数据库中有user_id=1的数据，我只是要做修改

@chowjiawei App\Models\UserModel Object ( [table:protected] => do_user [primaryKey:protected] => user_id [fillable:protected] => Array ( [0] => user_id [1] => user_name [2] => user_name [3] => user_sex [4] => user_openid [5] => user_avatar_url [6] => add_time ) [connection:protected] => mysql [keyType:protected] => int [incrementing] => 1 [with:protected] => Array ( ) [withCount:protected] => Array ( ) [preventsLazyLoading] => [perPage:protected] => 15 [exists] => 1 [wasRecentlyCreated] => [attributes:protected] => Array ( [user_id] => 1 [user_name] => 大萨达撒大所 [user_sex] => 0 [user_openid] => csacsacsacas [user_avatar_url] => scacsacsacsacas [add_time] => 2021-07-16 00:00:00 ) [original:protected] => Array ( [user_id] => 1 [user_name] => 大萨达撒大所 [user_sex] => 0 [user_openid] => csacsacsacas [user_avatar_url] => scacsacsacsacas [add_time] => 2021-07-16 00:00:00 ) [changes:protected] => Array ( ) [casts:protected] => Array ( ) [classCastCache:protected] => Array ( ) [dates:protected] => Array ( ) [dateFormat:protected] => [appends:protected] => Array ( ) [dispatchesEvents:protected] => Array ( ) [observables:protected] => Array ( ) [relations:protected] => Array ( ) [touches:protected] => Array ( ) [timestamps] => 1 [hidden:protected] => Array ( ) [visible:protected] => Array ( ) [guarded:protected] => Array ( [0] => * ) )

@chowjiawei 这个是我打印出来的数据，有值
