Question

我目前正在为我的组织开发自定义Kong插件。我正在尝试利用Kongs的身份验证和授权功能来编写一个权限插件，该插件将允许某些人和团体将不同的API组件提升到环境中。在设计插件的初始迁移时，我遇到了一个问题，就是不知道如何在PostgreSQL中正确表示我的实体关系。

我环顾四周，发现以下表示法是一种选择

"components"        UUID                ARRAY ELEMENT REFERENCES "elpt_components" ("id"),

但是我不确定这是否适用，或者我是否应该采用典型的桥梁实体方法。

我的daos.lua实体之一

local elpt_users = {
    primary_key = {"id"},
    name = "elpt_users",
    fields = {
        {id = typedefs.uuid},
        {consumer_id = {type = "foreign", reference = "consumers", required = true, on_delete = "cascade"}},
        {components = {type = "array", required = true, elements = {type = "foreign", reference = "elpt_components"}}},
        {environments = {type = "array", required = true, elements = {type = "foreign", reference = "elpt_environments"}}},
        {earliest_hour = {type = "number", required = true}},
        {earliest_minute = {type = "number", required = true}},
        {latest_hour = {type = "number", required = true}},
        {latest_minute = {type = "number", required = true}},
    }
}

在我为Postgres迁移时相应的表创建。

        CREATE TABLE IF NOT EXISTS "elpt_users" (
            "id"                UUID                PRIMARY KEY,
            "consumer_id"       UUID                REFERENCES "consumers" ("id") ON DELETE CASCADE,
            "components"        UUID                ARRAY ELEMENT REFERENCES "elpt_components" ("id"),
            "environments"      UUID                ARRAY ELEMENT REFERENCES "elpt_environments" ("id"),
            "earliest_hour"     INTEGER             REQUIRED,
            "earliest_minute"   INTEGER             REQUIRED,
            "latest_hour"       INTEGER             REQUIRED,
            "latest_minute"     INTEGER             REQUIRED,
        );

什么是我的用例的最佳方法，为什么？
