using METEOR#1.1.0.2 and doing an upsert on the server side gives me problems. It either complains that the syntax is wrong for insert or update, or am I just doing it wrong?
The code below will work on inserts but on updates throw:
Error: Update parameter cannot have both modifier and non-modifier fields.
Mail.upsert({ ma_user_id: userId }, {
ma_user_id: userId,
ma_address: userEmail,
ma_verified: false
}, function (e, r) {
console.log(e, r);
});
The code below works on updates but will throw this error on inserts:
MongoError:
The dollar ($) prefixed field '$exists' in 'removed.$exists' is not valid for storage.
Mail.upsert({ ma_user_id: userId }, { $set: {
ma_user_id: userId,
ma_address: userEmail,
ma_verified: false
}
}, function (e, r) {
console.log(e, r);
});
I have also tried this which gives me the error on update:
Error: Update parameter cannot have both modifier and non-modifier fields.
Mail.update({ ma_user_id: userId }, {
ma_user_id: userId,
ma_address: userEmail,
ma_verified: false
}, {
upsert: true
}, function (e, r) {
console.log(e, r);
});
The error message basically says that you cannot use the same field in both selector and modifier. So you have to remove ma_user_id from the modifier like this:
Mail.upsert({ ma_user_id: userId }, {
ma_address: userEmail,
ma_verified: false
}, function (e, r) {
console.log(e, r);
});

Trying to make a custom async schema validator in mongoose, to check that "tags" for a course being created contains at least one item. (Using SetTimeout() to simulate async). The part of the Schema for tags is :
tags: {
type: Array,
validate: {
isAsync: true,
validator: function (v, cb) {
setTimeout(() => {
//do some async work
const result = v && v.length > 0;
cb(result);
}, 3000);
},
message: "A course should have at least one tag!",
},
},
The code for creating a course is:
async function createCourse() {
const course = new Course({
name: "Node.js Course",
author: "Anon",
category: "web",
tags: [],
isPublished: true,
price: 13,
});
try {
const result = await course.save();
cl("createCourse result", result);
} catch (ex) {
cl("createCourse validate error", ex.message);
}
}
createCourse();
I have an empty array for tags and expected the caught error "A course should have at least one tag". Instead I am getting TypeError: cb is not a function for cb(result), the callback result? Even if I have an item in the tags array it still gives the callback error and in fact it displays the createCourse result BEFORE the schema async completes and then throws the error when it does complete! (If I dont use the async validator but just a plain validator then it works fine).
tags: {
type: Array,
validate: {
validator: function(v) {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve(v && v.length > 0);
}, 3000);
})
},
message: 'A course should have at least one tag.'
}
},
After trial and error, I came up with the solution below. No changes needed to createCourse(), just to the Schema tags section and added a delay function.
tags: {
type: Array,
validate: {
//isAsync: true,
validator: async function (v) {
await delay(3);
const result = v && v.length > 0;
return result;
},
message: "A Document should have at least one tag!",
},
},
And this calls a delay function, used to simulate a "real" async situation where this data may be being saved to a remote server.
const delay = (n) => {
return new Promise(function (resolve) {
setTimeout(resolve, n * 1000);
});
};
I'm using GraphQL with Meteor and Pup v2, and I have a problem accessing the users data via a special ID provided to every user on signup, this ID will be used in a link (mysite.com/user/specialId) so other users can view the searched users account. Problem is, I can't get the data with the special ID, I can't get any data back if I don't pass in the users _id provided by MongoDB. Below I have a bunch of the code used:
Attempt 1
I tried to use a custom on-the-go way just to be able to at least access the data to see if it works (and then implement it correctly later)
const GET_USER_DETAILS = gql`
query user($userId: String) {
user(userId: $userId) {
userId
username
_id
}
}
`;
Here I export so I can get the data:
export default compose(
graphql(GET_USER_DETAILS, {
options: ({ match }) => ({
fetchPolicy: 'no-cache',
variables: {
// existing specialId for testing purposes, to be replaced with match.params.userId
userId: "J4xZzvvhBDSEufnBn",
},
}),
}),
)(PublicProfileView);
This returns a 400 error Network error: Response not successful: Received status code 400 error and after multiple attempts, I could not fix it, so I tried a different approach...
Attempt 2
I tried to go deep into the files and change the GraphQL. Created a new query:
query userById($userId: String) {
userById(userId: $userId) {
...UserAttributes
}
}
(Mentioned fragment)
fragment UserAttributes on User {
_id
name {
...
}
username
emailAddress
oAuthProvider
roles {
...
}
settings {
...
}
userId
}
Tried to add new item in API:
type Query {
...
userById(userId: String): User
...
}
Resolver:
resolvers: {
Query: {
...
userById: (parent, args) => {
// Assuming args equals an object like { _id: '123' };
return UserQueries.userById(args);
},
},
},
query.js, attempt 1:
userById: (parent) => queryUsers.find({ userId: parent.userId }, { sort: { createdAt: 1 } }).fetch()
Attempt 2:
userById: (parent, args, context) => {
return queryUsers({
userId: parent.userId,
});
},
And finally
Attempt 3
I tried to modify the get query
const getQueryModified = (options) => {
// console.log(options.userId)
try {
return options.userId
? { 'userId': options.userId }
: { userId: options.userId };
} catch (exception) {
throw new Error(`[queryUsers.getQuery] ${exception.message}`);
}
};
Here is the original query I tried to modify:
const getQuery = (options) => {
try {
return options.search
? {
_id: { $ne: options.currentUser._id },
$or: [
{ 'profile.name.first': options.search },
{ 'profile.name.last': options.search },
{ 'emails.address': options.search },
// { 'userId': options.search },
{ 'services.facebook.first_name': options.search },
{ 'services.facebook.last_name': options.search },
{ 'services.facebook.email': options.search },
],
}
: { _id: options.currentUser._id };
} catch (exception) {
throw new Error(`[queryUsers.getQuery] ${exception.message}`);
}
};
Unfortunately this was also unsuccessful, the best I get from these when executing the below query is null...
userById(userId: "J4xZzvvhBDSEufnBn"){
username
}
All I want is to get the user data from their userId and not their _id, but I can't seem to figure out how to do it
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 [];
}
}
},
