数组中类型为graphql的对象的GraphQL字段 [英] GraphQL field of type graphql object within an array
本文介绍了数组中类型为graphql的对象的GraphQL字段的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在这里定义了一个graphQL对象:
I have a graphQL object defined here:
const graphql = require('graphql');
const { GraphQLObjectType } = require('graphql');
const ProductType = new GraphQLObjectType({
name: 'Product',
description: 'Product GraphQL Object Schemal Model',
fields: {
productId: { type: graphql.GraphQLString },
SKU: { type: graphql.GraphQLString },
quantity: { type: graphql.GraphQLFloat },
unitaryPrice: { type: graphql.GraphQLFloat },
subTotal: { type: graphql.GraphQLFloat },
discount: { type: graphql.GraphQLFloat },
totalBeforeTax: { type: graphql.GraphQLFloat },
isTaxAplicable: { type: graphql.GraphQLBoolean },
unitaryTax: { type: graphql.GraphQLFloat },
totalTax: { type: graphql.GraphQLFloat }
}
});
module.exports.ProductType = { ProductType };
然后,我想在另一个GraphQL对象中使用此ProductType,但是我需要将该对象作为数组结构,如下所示:
And then, I want to use this ProductType inside another GraphQL object, but I need that object to be an array structure, something like this:
const graphql = require('graphql');
const { GraphQLObjectType } = require('graphql');
const { ProductType } = require('./product');
const ShoppingCartType = new GraphQLObjectType({
name: 'ShoppingCart',
description: 'Shopping Cart GraphQL Object Schema Model',
fields: {
cartId: { type: graphql.GraphQLString },
userId: { type: graphql.GraphQLString },
products: [{ type: ProductType }]
}
});
module.exports.ShoppingCartType = { ShoppingCartType };
这可能吗?
推荐答案
您需要使用 GraphQLList 包装器,如下所示:
You need to wrap your existing type using the GraphQLList wrapper, like so:
products: { type: new GraphQLList(ProductType) }
