Collect email addresses for all individuals in the array using Meteor

I am currently working on a project where I need to send emails to every individual in an array. To achieve this, I require the email address of each person. I have a collection called Benutzer/benutzer which includes the name and email address of each person.

Below is the code snippet from the client side:

Template.NeuesEvent.onCreated(function() {
    this.subscribe('events');
    this.subscribe('friends');
    this.subscribe('benutzer');
});

Template.NeuesEvent.events({
    "submit .add-event": function(event){
        var Name = event.target.name.value;
        var Beschreibung = event.target.beschreibung.value;
        var Datum = event.target.Datum.value;
        var Autor = Meteor.userId();
        var eingeladene = []; <-- this is the array
             $.each($('.FreundeCheckbox:checked'), function(){            
                eingeladene.push($(this).val());
            });

       var email = Meteor.Benutzer.findOne({"email": eingeladene});<<------

       <<---- here i want to grab the email adress 


        if (Name == "")
        {
            confirm("Das Event braucht einen Namen ;)")
        }
        else {

        Meteor.call('addEvent', Name, Beschreibung, Datum, eingeladene, Autor, email) <<--
<<------and paste the information here

        event.target.name.value = "";
        event.target.beschreibung.value = "";
        FlowRouter.go('/meineEvents');

        return false;
    }
    }
});

This part of my method.js does not contain the email function yet, but I am aware of how to implement it:

Meteor.methods({
    addEvent(Name, Beschreibung, Datum, eingeladene, Autor, email) {
         Events.insert({
            Name: Name,
            Beschreibung: Beschreibung,
            erstelltAm: new Date(),
            Datum: Datum,
            Eingeladen: eingeladene,
            Autor: Autor
        });

SSR.compileTemplate('InviteEmail', Assets.getText('Invite-Email.html'));
        var emailData = {
            Name: Name,
            Beschreibung: Beschreibung,
            erstelltAm: new Date(),
            Datum: Datum,
            Eingeladen: eingeladene,
            Autor: Autor
        };

    Email.send({
        to: email, <<<-----everytime a new one 
        from: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="117469707c617d7451747c70787d3f727e7c">[email protected]</a>",
        subject: "Einladung",
        html: SSR.render('InviteEmail', emailData),
      });
        }
    });

Now that you understand my objective, please assist me with two challenges - obtaining the email addresses and iterating over the `Email.send` function for each email address.

Answer №1

Kindly refrain from inserting comments into the code without providing meaningful explanations:

Incorrect Usage of Commenting:

var invited = []; <-- this is the array

Improved Approach:

var invited = []; // <-- this is the array

It's important to note that 'invited' is an array, therefore this line does not return anything:

var email = Meteor.Users.findOne({"email": invited});

The correct method would be:

var email = Meteor.Users.findOne({"email": {$in: invited}});

Alternatively, send an array of emails to the function and handle operations there. Here is an example:

Template.NewEvent.events({
    "submit .add-event": function(event){
        var Name = event.target.name.value;
        var Description = event.target.description.value;
        var Date = event.target.Date.value;
        var Author = Meteor.userId();
        var invited = []; 
         $.each($('.FriendsCheckbox:checked'), function(){            
            invited.push($(this).val());
        });

        // Email retrieval is unnecessary at this stage

        if (Name == "")
        {
            confirm("The event needs a name ;)")
        }
        else {

        // Removed Author and email as they are not required here
        Meteor.call('addEvent', Name, Description, Date, invited);

        event.target.name.value = "";
        event.target.description.value = "";
        FlowRouter.go('/myEvents');

        return false;
    }
    }
}); 

Meteor.methods({
    'addEvent': function(Name, Description, Date, invited) {
        this.unblock();
        var Author = Meteor.users.findOne(this.userId);

         Events.insert({
            Name: Name,
            Description: Description,
            createdOn: new Date(),
            Date: Date,
            Invited: invited,
            Author: Author
        });

        SSR.compileTemplate('InviteEmail', Assets.getText('Invite-Email.html'));
        var emailData = {
            Name: Name,
            Description: Description,
            createdOn: new Date(),
            Date: Date,
            Invited: invited,
            Author: Author
        };

        // Determine if fetching emails from the collection is necessary

        for (var i in invited) {
            var email = Meteor.Users.findOne({"email": invited[i]});
            if (!email) {
                continue;
            }


            Email.send({
                to: email, <<<-----everytime a new one 
                from: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fe9b869f938e929bbe9b939f9792d09d9193">[email protected]</a>",
                subject: "Invitation",
                html: SSR.render('InviteEmail', emailData),
            });
        }
    }
