Hey guys,

I have a schema with multiple index, and using the plugin 'mongoose-plugin-autoinc' to auto increment value
Now each time I am saving I get a duplicate along with this First param to schema.plugin() must be a function, got "object"

const mongoose = require('mongoose');
const autoIncrement = require('mongoose-plugin-autoinc');

// Initialize Auto Increment 
const connection = mongoose.createConnection("mongodb://localhost:27017/food");

const partnerSchema = new mongoose.Schema({
    partnerID: { type: Number, index: true, unique: true }
});

partnerSchema.plugin(autoIncrement, {
    model: 'Partner',
    field: 'partnerID',
    startAt: 100300,
    incrementBy: 3
});

const Partner = connection.model('Partner', partnerSchema);
module.exports = Partner;

can anyone suggest ?

hey @warlockdn :)

try: const { autoIncrement } = require('mongoose-plugin-autoinc') instead

or const autoIncrement = require('mongoose-plugin-autoinc').autoIncrement

the first way is preferable to me, as it's visually cleaner, but it's dependent on a semi-modern node. so if you're rockin node 4 or something the second syntax is valid.

hey @lineus that did the trick. But why did we need to use the { autoIncrement } here. Can you lemme know.

it's because of the way the module.exports are setup in that version of the package. iow, it doesn't explicitly say module.exports = autoIncrement in that module, so you have to explicitly ask for it with one of those two versions of the require statement above.

@warlockdn check out the docs on destructuring on mdn Objects are covered about half way down.

lol I guess I didn't hit enter a few hours ago when I wrote that :)
