对象查询数组(带有JSONB的Postgres, Laravel 5)

I've got this data in a JSONB field:

我在JSONB字段中获得了这些数据:

[
    'first_name' => 'Philipp',
    'last_name' => 'Kühn',
    'size' => 170,
    'hobbies' => [
      'daily' => 'beer',
    ],
    'skills' => [
      'drink beer',
      'drink more beer',
    ],
]

I'm pretty new to Laravel and Postgres so I wanted to do some basic queries.

我对Laravel和Postgres非常陌生，所以我想做一些基本的查询。

Here are some queries that works fine: (json is the name of the column)

以下是一些运行良好的查询:(json是列的名称)

$users = User::whereRaw("json ->> 'first_name' = 'Philipp'")->get();

$users = User::whereRaw("json ->> 'size' > '160'")->get();

$users = User::whereRaw("json #>> '{hobbies, daily}' = 'beer'")->get();

Now I want to check if drink beer is in skills and the following code doesn't work:

现在我想检查一下喝啤酒是否有技巧，下面的代码是否有效:

$users = User::whereRaw("json -> 'skills' ? 'drink beer'")->get();

Here I got a syntax error:

这里有一个语法错误:

SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "$1"
LINE 1: select * from "users" where json ->> 'skills' $1 'drink beer...
^ (SQL: select * from "users" where json ->> 'skills' ? 'drink beer')

How can I search for drink beer?

我怎么能搜索喝啤酒?

As suggested by @tapoueh on twitter, maybe a work around would be to use the operator's underlying function: jsonb_exists(jsonb, text). So your query would be

正如@tapoueh在twitter上建议的那样，可能需要使用运营商的底层功能:jsonb_exists(jsonb, text)。所以你的查询是。

$users = User::whereRaw("jsonb_exists(json -> 'skills', 'drink beer')")->get();
