simpl-schema: How to create an schema that validates every property of an object is of a certain schema? - meteor

Question

Basically... I have something of the following type: record<string, User> (aka Map<String,User>). Basically, an object that can have any field, as long as it is an user.
How do I create an Schema that validates that?

Answer 1

There is an older question that seems to ask the same thing Can SimpleSchema express "object with custom keys and specific schema for values"? , however being asked for an older version of this library.
The accepted answer assumes the usage of Custom Validators

Answer 2

https://github.com/longshotlabs/simpl-schema#type
Another SimpleSchema instance, meaning Object type with this schema
const userSchema = new SimpleSchema({
username: {
type: String,
// For accounts-password, either emails or username is required, but not both. It is OK to make this
// optional here because the accounts-password package does its own validation.
// Third-party login packages may not require either. Adjust this schema as necessary for your usage.
optional: true,
},
emails: {
type: Array,
// For accounts-password, either emails or username is required, but not both. It is OK to make this
// optional here because the accounts-password package does its own validation.
// Third-party login packages may not require either. Adjust this schema as necessary for your usage.
optional: true,
},
'emails.$': {
type: Object,
},
'emails.$.address': {
type: String,
regEx: SimpleSchema.RegEx.Email,
},
'emails.$.verified': {
type: Boolean,
},
// Use this registered_emails field if you are using splendido:meteor-accounts-emails-field / splendido:meteor-accounts-meld
registered_emails: {
type: Array,
optional: true,
},
'registered_emails.$': {
type: Object,
blackbox: true,
},
createdAt: {
type: Date,
},
profile: {
type: Schema.UserProfile,
optional: true,
},
// Make sure this services field is in your schema if you're using any of the accounts packages
services: {
type: Object,
optional: true,
blackbox: true,
},
// DISCLAIMER: This only applies to the first and second version of meteor-roles package.
// https://github.com/Meteor-Community-Packages/meteor-collection2/issues/399
// Add `roles` to your schema if you use the meteor-roles package.
// Option 1: Object type
// If you specify that type as Object, you must also specify the
// `Roles.GLOBAL_GROUP` group whenever you add a user to a role.
// Example:
// Roles.addUsersToRoles(userId, ["admin"], Roles.GLOBAL_GROUP);
// You can't mix and match adding with and without a group since
// you will fail validation in some cases.
roles: {
type: Object,
optional: true,
blackbox: true,
},
// Option 2: [String] type
// If you are sure you will never need to use role groups, then
// you can specify [String] as the type
roles: {
type: Array,
optional: true,
},
'roles.$': {
type: String,
},
// In order to avoid an 'Exception in setInterval callback' from Meteor
heartbeat: {
type: Date,
optional: true,
},
});
const someOtherSchema = new SimpleSchema({
useDocument: {
type: userSchema
},
});
