How to create unique keys in KeystoneJS

you need to change the add method of your model like this:

Word.add({    word: { type: Types.Text, required: true, initial: "New word", index: true, unique: true }});

i tried it and worked for me, notice i added unique:true

i created a keystone project using yeoman's keystone generator, and created a model like yours (you can find it in model/Test.js), then in the admin page when i try to add the same word twice i get:

Error saving changes to Word 569b98f27b5786db1c367b7a:{ [MongoError: E11000 duplicate key error collection: test_unique_field.words index: word_1 dup key: { : "test" }]  name: 'MongoError',  code: 11000,  err: 'E11000 duplicate key error collection: test_unique_field.words index: word_1 dup key: { : "test" }' }

this is the link to the repo if you want to play with it: keystonejs_test_unique

I was only able to enforce the uniqueness by using the mongoose-unique-validator module like so:

var keystone = require('keystone');var Types = keystone.Field.Types;var uniqueValidator = require('mongoose-unique-validator');var Word = new keystone.List('Word', {     map: { name: 'word' }});Word.add({    word: { type: Types.Text, index: true, unique: true }});Word.schema.plugin(uniqueValidator);Word.defaultColumns = 'word';Word.register();
