Keystone-classic: When i started app getting “Unknown keystone list” Error In Keystone 4.0

[rigalpatel001]

I have added routes to post-event data.

 var keystone = require('keystone');
 var Event = keystone.list('Event');
 module.exports = function (req, res) {
  if (!req.body.name || !req.body.startTime || !req.body.endTime) {
  return res.send({ status: 'incomplete data set' });
 }
var newEvent = new Event.model();
Event.updateItem(newEvent, req.body, function (error) {
res.locals.enquirySubmitted = true;
 if (error) res.locals.saveError = true;
res.render('addEvent');
});
};

When I start the app I am getting below error.

if (!result) throw new ReferenceError('Unknown keystone list ' + JSON.stringify(key)); ^

ReferenceError: Unknown keystone list "Events" at Keystone.list (/Users/rigalpatel/KS_shopingcart/node_modules/keystone/lib/core/list.js:7:21) at Object.

Would you please provide your feedback. suggestion how to fix above issue.

var Event = keystone.list('Event');

@rigalpatel001: You need to change this line to keystone.List('Event');.

I'm assuming you copied this from Part 4 of the Getting started tutorial, which has the same typo.

Hello,
Thanks for your quick replay and solution.

Now I am getting another error.

"Event.model is not a constructor"

Would you please let me your feedback on how to fix it.

Thanks

Any updates? I have the same problem as @rigalpatel001

@ rigalpatel001 the error comes from using keystone.List instead of keystone.list. The List method, AFAIK, doesn't have a model constructor. It's used for creating mongoose schemas, not for accessing them.

I'm still having the original bug though: Unknown keystone list Wallet" in my case. A few suspicions:

1. Lists can't be accessed from a post save hook. This is countered in part by the fact that I conveniently accessed another list from a pre save hook.
2. The User model was registered before the wallet model. This doesn't make sense however
3. I am meant to declare an explicit relationship between users and their wallets. All that this does is defeat the purpose of abstracting the wallets entirely.

I'll need a fix really soon. Here's my code:

User Model

'use strict';

const keystone = require('keystone');
const Types = keystone.Field.Types;
let Country = keystone.list('Country');
let Wallet = keystone.list('Wallet');


let User = new keystone.List('User', {history: true});

User.add({
    name: { type: Types.Name, required: true, index: true },
    email: { type: Types.Email, initial: true, required: true, unique: true, index: true },
    password: { type: Types.Password, initial: true, required: false },
    phone: { type: Types.Text, unique: true },
    avatar: { type: Types.Text },
    registrationEnd: { type: Types.Date },
    registrationStart: { type: Types.Date },
    utitle: { type: Types.Relationship, ref: 'Title' },
    dob: { type: Types.Date },
    permAddress: { type: Types.Location, state: { type: Types.Relationship, ref: 'State' }, country: { type: Types.Relationship, ref: 'Country' } },
    sor: { type: Types.Relationship, ref: 'State' },
    lga: { type: Types.Relationship, ref: 'LGA' },
    religion: { type: Types.Relationship, ref: 'Religion' },
    marital: { type: Types.Relationship, ref: 'Marital' },
    sex: { type: Types.Select, options: 'male, female' },
    // wallet: { type: Types.Relationship, ref: 'Wallet', many: false },
    education: { type: Types.Relationship, ref: 'Education', dependsOn: { isClient: true } },
    seenLawyer: { type: Boolean, default: false, dependsOn: { isClient: true } },
    occupation: { type: Types.Relationship, ref: 'Occupation', dependsOn: { isClient: true } },
    firm: { type: Types.Text, dependsOn: { isLawyer: true } },
    lawyerSince: { type: Types.Date, dependsOn: { isLawyer: true } },
    areas: { type: Types.Relationship, ref: 'LawArea', default: false , many: true, dependsOn: { isLawyer: true } },    
}, 'Permissions', {
    isAdmin: { type: Boolean, label: 'Can access Keystone', index: true, default: false },
    isLawyer: { type: Boolean, index: true, default: false },
    isClient: { type: Boolean, index: true, default: false },
});


// User.relationship({ path: 'wallet', ref: 'Wallet', refPath: 'currentBalance' });

User.schema.virtual('canAccessKeystone').get(function () {
    return this.isAdmin;
});

User.schema.virtual('law').get(function () {
    return this.isLawyer;
});

User.schema.virtual('client').get(function () {
    return this.isClient;
});

User.schema.virtual('fullname').get(function () {
    return this.name.first + ' ' + this.name.last;
});

User.schema.pre('save', function(next) {
let thisUser = this;
Country.model.findOne({name: 'India'}).then((result) => {
thisUser.permAddress.country = result._id;
next();
});
});

// Where the error lies
User.schema.post('save', function(next) {
let thisUser = this;
console.log(thisUser._id) // Works well
Wallet.model({owner: thisUser._id}).save(function(err) => {
if(err) console.error('User does not have a valid wallet');
next();
});
});

User.defaultColumns = 'name, email, roles, isAdmin';
User.register();

And the Wallet model, duly registered

'use strict';

const keystone = require('keystone');
const Types = keystone.Field.Types;

let Wallet = new keystone.List('Wallet');


Wallet.add({
    owner: { type: Types.Relationship, ref: 'User', index: true, required: true, initial: false },
    previousBalance: { type: Types.Number, default: 0 },
    currentBalance: { type: Types.Number, default: 0, required: true },
});

//Wallet.relationship({ path: 'owner', ref: 'User', refPath: '_id' });

Wallet.register();

It's still unclear where I've missed something.

Hello,
Thanks for your quick replay and solution.

Now I am getting another error.

"Event.model is not a constructor"

Would you please let me your feedback on how to fix it.

Thanks

hi,

1. do not change to keystone.List('Event'); stay with the little "l".
2. in your keystone.js, make sure you put keystone.import("models"); before keystone.set("routes", require("./routes"));

and your good to go, mate.
