What is the best way to change an email address in meteor?

Hey there! I'm currently working on an app using Meteor and I need to update my email address. The process involves utilizing the Meteor accounts package.

In my form, I pass an email value into an accountDetails object, which will then be used in a method to update my profile (including my email):

Meteor.users.update({_id: this.userId},
{
   $set: {
            'emails.$.address': accountsDetail.email
    }

});

However, when I try to execute this code, I encounter the following error:

Exception while invoking method 'saveAccountInfo' MongoError: The positional operator did not find the match needed from the query. Unexpanded update: emails.$.address

Below is my user schema for reference:

{
"_id" : "12345",

"emails" : [
    {
        "address" : "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2f4e4d4c1e1d1c6f48424e4643014c4042">[email protected]</a>",
        "verified" : false
    }

If anyone can assist me with resolving this issue, I would greatly appreciate it. Thank you in advance!

Answer №1

When you are certain that the user only has one address, you can utilize emails.0.address instead of emails.$.address.

This method is suitable for most scenarios, except when a user has multiple emails associated with their account.

If you are operating on the server exclusively, you have the option to employ the positional operator for updating a specific email among several addresses. In such cases, you must specify the current email in the update query. For example: 

{_id: this.userId, 'emails.$.address' : <current address> }

It is important to note that the $ positional update operator is currently not supported in the mongo client within Meteor.

Answer №2

Since each user can have multiple addresses (stored as an array), you must specify which key you wish to update (in this case, the address itself). For more information, refer to .

Meteor.users.update({_id: this.userId, "emails.address":"<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="98f5fdd8fcf7f5f9f1f6b6fbf7f5">[email protected]</a>"},
$set:{'emails.$.address': accountsDetail.email}
});

If each user only has one email, another approach could be to remove the old email and add the new one. Visit http://docs.mongodb.org/manual/reference/operator/update/pop/ for details.

I hope this explanation proves helpful.

Best regards,

René
