Mongoose + GraphQL(Apollo Server)架构

问题描述 投票:0回答:1

我们有db收集,这有点复杂。我们的许多键是JSON对象,其中字段不是固定的,并且基于用户在UI上给出的输入而改变。我们应该如何为这种复杂类型编写mongoose和GraphQL Schema?

{
    "_id" : ObjectId("5ababb359b3f180012762684"),
    "item_type" : "Sample",
    "title" : "This is sample title",
    "sub_title" : "Sample sub title",
    "byline" : "5c6ed39d6ed6def938b71562",
    "lede" : "Sample description",
    "promoted" : "",
    "slug" : [ 
        "myurl"
    ],
    "categories" : [ 
        "Technology"

                    }
                },
                "subHeader" : {
                    "type" : "",

我相信Mongoose有混合类型,但我如何在Apollo GraphQL Server和Mongoose Schema中表示这种复杂类型。此外,目前我的解析器只是models.product.find()。因此,如果我有这样复杂的类型,需要了解需要对我的解析器进行哪些更新。

如果我获得GraphQL Apollo模式,mongoose模式和解析器的完整解决方案,那将是很棒的。

终于找到问题的解决方案。

您可以声明新类型并在typeDef中为GraphQL Schema引用它。

在mongoose模型中,您可以将其引用为{type:Array}
