whereJsonContains Laravel 5.6 不起作用?

2021-12-18 00:00:00 json php mysql eloquent laravel-5.6 
$rosters = EventRosters::where('event_id', $event_id)
    ->whereJsonContains('players', $user_id)
    ->whereNull('deleted_at')
    ->get();

上面的 eloquent 查询似乎只在 'players' json 数组中有单个项目时才有效.

The eloquent query above seems to only work when there is a single item in the 'players' json array.

存储在数据库中的数据如下所示:[1] vs ["1","2"]

The data stored in the database looks as follows: [1] vs ["1","2"]

whereJsonContains 仅在数据库中看到 [1] 时才起作用，而在看到 ["1","2"] 时不起作用，有什么原因吗?

Is there a reason the whereJsonContains is only working when it sees [1] in the db but not when it sees ["1","2"] ?

我对 Laravel 还很陌生，并且一直在努力解决这个问题.

I am pretty new to Laravel and have been struggling with this one a bit.

推荐答案

数据类型必须匹配:

// [1, 2]
->whereJsonContains('players', 1)   // Works.
->whereJsonContains('players', '1') // Doesn't work.

// ["1", "2"]
->whereJsonContains('players', '1') // Works.
->whereJsonContains('players', 1)   // Doesn't work.
