问您尝试从mongoose模型生成名为"Projects“的GraphQL类型，但此类型已存在于SchemaComposer中

EN

import { composeMongoose } from 'graphql-compose-mongoose'
import { SchemaComposer } from 'graphql-compose'
import { Pages } from '../../mongoose/models/PagesModel.js'
import { Projects } from '../../mongoose/models/ProjectsModel.js'

const gqlSchemaComposerBuilder = (database) => {
    const gqlSchemaComposer = new SchemaComposer()

    const ProjectsTC = composeMongoose(Projects, {})
    const PagesTC = composeMongoose(Pages(database), {})

    gqlSchemaComposer.Query.addFields({
        pageMany: PagesTC.mongooseResolvers.findMany(),
        pageOne: PagesTC.mongooseResolvers.findOne(),

        projectMany: ProjectsTC.mongooseResolvers.findMany(),
        projectOne: ProjectsTC.mongooseResolvers.findOne()
    })

    gqlSchemaComposer.Mutation.addFields({
        projectCreateOne: ProjectsTC.mongooseResolvers.createOne(),
        projectUpdateOne: ProjectsTC.mongooseResolvers.updateOne(),
        projectRemoveOne: ProjectsTC.mongooseResolvers.removeOne()
    })

    return gqlSchemaComposer.buildSchema()
}

export default gqlSchemaComposerBuilder

{"errors":[{"message":"You try to generate GraphQL Type with name Projects from mongoose model but this type already exists in SchemaComposer.
