I have a schema defined below and how can I change the predefined schema key (summary: key) via meteor template?
Schemas.Books = new SimpleSchema(
{
summary: {
type: String
}
}
);
For instance, I want to change this key through a session variable that was defined by router or through a user input.
Not Sure, Try this
If your schema is like this
Books = new SimpleSchema(
{
summary: {
type: String
}
}
);
then in tempalte helpers,
Books._schema.summary.type = function() {
return Session.get("typeValue");
};
In my project I have schema like this
RegisterSchema = new SimpleSchema({
name: {
type: String
},
email: {
type: String,
regEx: SimpleSchema.RegEx.Email
},
password: {
type: String,
label: "Password",
min: 8
},
confirmPassword: {
type: String,
label: "Confirm Password",
min: 8,
custom: function () {
if (this.value !== this.field('password').value) {
return "passwordMismatch";
}
}
}
});
and I'm dynamically setting optional value for email like
RegisterSchema._schema.email.optional = function() { return true };
this worked for me.
All d best
This is not the thing that I'm trying to do but I have learned a new trick : )
I want to change the schema key that I described above like this.
Books = new SimpleSchema(
{
bookName: {
type: String
}
}
);
Changing summary: with bookName:
Actually I want to define schema keys dynamically with respect to user information (userId, userName etc.).

Forms of this question have been asked a few times, but I've been unable to find a solution:
I have a schema like this (simplified):
StatusObject = new SimpleSchema({
statusArray: [statusSchema]
});
where statusSchema is
{
topicId:{
type: String,
optional: true
},
someInfo:{
type: Number,
optional: true,
decimal: true
},
otherInfo:{
type: Number,
optional: true
}
}
I am trying to upsert - with the following meteor method code:
var upsertResult = BasicInfo.update({
userId: this.userId,
statusArray: {
$elemMatch: { topicId : newStatus.topicId }
}
}, {
$set: {
"statusArray.$.topicId": newStatus.topicId,
"statusArray.$.someInfo": newStatus.someInfo,
"statusArray.$.otherInfo": newStatus.otherInfo
}
}, {
multi: true,
upsert: true
});
But I keep getting an error: statusArray must be an array
I thought by adding the $, I was making sure it is recognized as an array? What am I missing?
It seems (after your clarification comments), that you want to find a document with particular userId and modify its statusArray array using one of these scenarios:
Update existing object with particular topicId value;
Add a new object if the array doens't have one with particular topicId value.
Unfortunately, you can't make it work using just one DB query, so it should be like this:
// try to update record
const updateResult = BasicInfo.update({
userId: this.userId,
'statusArray.topicId': newStatus.topicId
}, {
$set: {
"statusArray.$": newStatus
}
});
if (!updateResult) {
// insert new record to array or create new document
BasicInfo.update({
userId: this.userId
}, {
$push: {
statusArray: newStatus
},
$setOnInsert: {
// other needed fields
}
}, {
upsert: true
});
}
Your code is treating StatusArray as an object,
Before you do the upsert, build the status array first, assuming that your current value is currentRecord
newStatusArray = currentRecord.statusArray
newStatusArray.push({
topicId: newStatus.topicId,
someInfo : newStatus.someInfo,
otherInfo: newStatus.otherInfo
})
and in the upsert, simply refer to it like this
$set: { statusArray: newStatusArray}
I want to make a SimpleSchema for documents with the the following format:
{
...,
permissions: {
foo: {allow: ["user1", "user2"]},
bar: {allow: ["admin"]},
}
}
If foo and bar were well-known strings in the schema, I would just do this:
const PermissionsSchema = new SimpleSchema({
allow: {type: [String]},
});
new SimpleSchema({
...,
'permissions.foo': {
type: PermissionSchema,
},
'permissions.bar': {
type: PermissionSchema,
},
})
However, in this case, there can be arbitrary string keys, not just foo and bar. The values must always match PermissionsSchema. Is there a way to express this?
Custom validators to the rescue!
import { ValidationError } from 'mdg:validation-error';
function permissionsValidator(keyRegEx) {
if (!(keyRegEx instanceof RegExp)) {
throw new Error('must pass a regular expression');
}
return function() {
// https://github.com/aldeed/meteor-simple-schema#custom-validation
const value = this.value;
for (let key in value) {
if (value.hasOwnProperty(key)) {
if (!keyRegEx.test(key)) {
return 'regEx';
}
try {
PermissionSchema.validate(value[key]);
} catch (ex) {
if (ex instanceof ValidationError) {
return ex.error;
}
}
}
}
};
}
new SimpleSchema({
...,
permissions: {
type: Object,
custom: permissionsValidator(/^.*$/),
blackbox: true,
optional: true,
defaultValue: {},
},
});
The error messages that come out are rubbish, though. Improvements or better strategies still welcome.
i have quickform once the submit button clicked, this method is fired
submitPost: function (app) {
check(app, {
title: String,
description: String,
category: String,
price: Number
});
var knownId = Products.insert(app);
Products.update({ _id: knownId }, { $set:{screenShots: scs, previewImage: pi, sourceCode: zip }});
}
the submit button wasn't working when i didn't give "screenShots, previewImage, and sourceCode" a default values in a collection.
Once i gave them a default value like it is shown below
previewImage: {
type: String,
defaultValue: "jjj",
},
sourceCode: {
type: String,
defaultValue: "jjj",
},
screenShots: {
type: [String],
autoValue: function() {
return [];
}
},
now the submit button in the form is working and the update method is triggered. it updates both "previewImage and sourcCode" but "screenShots" is still empty.
am not sure but i believe the problem has to do with autoValue which i should make it a default value, but how do i give an element that of type array of string a default value?
or the problem has to do with something else?
use optional: true in the schema if the value is optional, and it will pass check if it is empty.
The autoValue option is provided by the SimpleSchema package and is documented there. Collection2 adds the following properties to this for any autoValue function that is called as part of a C2 database operation:
isInsert: True if it's an insert operation
isUpdate: True if it's an update operation
isUpsert: True if it's an upsert operation (either upsert() or upsert: true)
So If you want to provide the autoValue while updating you have to use isUpdate in your schema like this.
createdAt: {
type: Date,
autoValue: function() {
if (this.isInsert) {
return new Date();
} else if (this.isUpsert) {
return {$setOnInsert: new Date()};
} else {
this.unset(); // Prevent user from supplying their own value
}
}
},
So your schema will be something like this:
previewImage: {
type: String,
defaultValue: function() {
if (this.isInsert) {
return 'fff';
} else if (this.isUpdate) {
return 'fff';
}
},
sourceCode: {
type: String,
defaultValue:function() {
if (this.isInsert) {
return 'jjj';
} else if (this.isUpdate) {
return 'jjj';
}
},
screenShots: {
type: [String],
autoValue: function() {
if (this.isInsert) {
return [];
} else if (this.isUpdate) {
return [];
}
}
},

I'm trying to validate my data against a SimpleSchema before it gets submitted to the collection but for some reason I'm not able to do so with this error.
Exception while invoking method 'createVendorCategory' { stack: 'TypeError: Cannot call method \'simpleSchema\' of undefined
I have one collections with two SimpleSchemas as follows.
Vendors = new Mongo.Collection('vendors'); //Define the collection.
VendorCategoriesSchema = new SimpleSchema({
name: {
type: String,
label: "Category"
},
slug: {
type: String,
label: "Slug"
},
createdAt : {
type: Date,
label: "Created At",
autoValue: function(){
return new Date()//return the current date timestamp to the schema
}
}
});
VendorSchema = new SimpleSchema({
name: {
type: String,
label: "Name"
},
phone: {
type: String,
label: "Phone"
},
vendorCategories:{
type: [VendorCategoriesSchema],
optional: true
}
});
Vendors.attachSchema(VendorSchema);
The vendorCategory will be added after the Vendor document is created by the user.
Here is what my client side looks like.
Template.addCategory.events({
'click #app-vendor-category-submit': function(e,t){
var category = {
vendorID: Session.get("currentViewingVendor"),
name: $.trim(t.find('#app-cat-name').value),
slug: $.trim(t.find('#app-cat-slug').value),
};
Meteor.call('createVendorCategory', category, function(error) {
//Server-side validation
if (error) {
alert(error);
}
});
}
});
And here is what my server side Meteor.methods look like
createVendorCategory: function(category)
{
var vendorID = Vendors.findOne(category.vendorID);
if(!vendorID){
throw new Meteor.Error(403, 'This Vendor is not found!');
}
//build the arr to be passed to collection
var vendorCategories = {
name: category.name,
slug: category.slug
}
var isValid = check( vendorCategories, VendorSchema.vendorCategories.simpleSchema());//This is not working?
if(isValid){
Vendors.update(VendorID, vendorCategories);
// return vendorReview;
console.log(vendorCategories);
}
else{
throw new Meteor.Error(403, 'Data is not valid');
}
}
I'm guessing this is where the error is coming from.
var isValid = check( vendorCategories, VendorSchema.vendorCategories.simpleSchema());//This is not working?
Any help would be greatly appreciated.
Since you've already defined a sub-schema for the sub-object you can directly check against that:
check(vendorCategories,VendorCategoriesSchema)
I have the following SimpleSchema
Schema.Team = new SimpleSchema({
name:{
type:String
},
members: {
type: [Schema.User],
optional:true
}
});
I would like to insert (on the server) a new team document with the current user, as a reference (not as an embedded document).
I have tried:
Teams.insert({name:"theName",members:[Meteor.user()]}) // works but insert the user as an embedded doc.
Teams.insert({name:"theName",members:[Meteor.user()._id]}) // Error: 0 must be an object
I have also tried in two steps:
var id = Teams.insert({name:teamName});
Teams.update({ _id: id },{ $push: { 'users': Meteor.user()._id } });
Then I have another error I don't understand: Error: When the modifier option is true, validation object must have at least one operator
So how can I insert a document with a reference to another schema?
If you just want to store an array of userIds in your Team collection try:
Schema.Team = new SimpleSchema({
name:{
type:String
},
members: {
type: [String],
optional:true
}
});
Then
Teams.insert({ name: "theName", members: [Meteor.userId()] });
Should work. Later when you want to add an additional id you can just:
Teams.update({ _id: teamId },{ $addToSet: { members: Meteor.userId() }});
The following is probably the syntax you are after, assuming you are also using AutoForm.
If you are using collection2, you can also add an autovalue for when a team is created to automatically add the creator to that team for more convenience.
Schema.Team = new SimpleSchema({
name: {
type:String
},
members: {
type: [String],
defaultValue: [],
allowedValues: function () {
// only allow references to the user collection.
return Meteor.users.find().map(function (doc) {
return doc._id
});
},
autoform: {
// if using autoform, this will display their username as the option instead of their id.
options: function () {
return Meteor.users.find().map(function (doc) {
return {
value: doc._id,
label: doc.username // or something
}
})
}
},
autoValue: function () {
if (this.isInsert && !this.isFromTrustedCode) {
return [this.userId];
}
}
}
});
