        poolSize: 5,
        native_parser: true
    }

    let user = new User({
        account: 'test',
        password: 'test'
    })
    await user.save()
    ctx.body = 'OK'

    let user = new User({
        account: 'test',
        password: 'test'
    })
    //or
    let user = ctx.document('User', {

    port: 27017,
    database: ctx => {
        return ctx.headers['x-app']
    },
    schemas: './schemas',
    mongodbOptions:{
        poolSize: 5,
        native_parser: true

    mongodbOptions:{
        poolSize: 5,
        native_parser: true
    }
}))

app.use(async (ctx, next) => {
    let User = ctx.model('User')
    let user = new User({
        account: 'test',
        password: 'test'
    })
