meteor: show alert on created user - meteor

Question

I want to show to the user a message like: "I have sent a email to activate your account".
I cannot because when the user has been created I have not found a hook for this.
Do you know some way to do this?
I currently show a message permanently, but I don't want this way. I just want to show once when user is singed up.

Answer 1

Well there are 2 options here, if you are creating the user on the client side, just use
Accounts.createUser({email: email, password: password}, function(err) {
if(!err){
alert(""I have sent a email to activate your account")
}
});
Or if you are creating the user from a method, it should look like this.
//Server.js
Meter.method({
createUser:function(username,email,password){
//create user logic.
}
})
And on the client it should look like this.
Meteor.call('createUser',username,email,password,function(err,result){
if(!err){
alert(""I have sent a email to activate your account")
}
});
On both cases we are using an extra parameter, named callback this function, accept 2 other parameters wich are err,result, so if there is not error when the accounts its created, the alert should be triggered

Answer 2

You should be able to add the alert in the callback from createUser() on the client. Assuming you have something like a form that you submit to create the user, then you would do ...
Template.myTemplate.events({
'submit #new-user-form': function(event) {
// These next few lines will depend on what your template looks like and what data you require on login
// Here I've assumed just username and pw in appropriately-named inputs on your page
var email = $('#email-input').val();
var password = $('#password-input').val();
event.preventDefault();
Accounts.createUser({email: email, password: password}, function(error) {
if (error) { alert("There was an error!"); }
else { alert("I have sent you an email to verify your account"); }
});
}
});
If you want to accomplish this behavior with accounts-ui installed, the documentation doesn't show anything you can hook into. However, you can do it manually like so:
Template.myTemplate.events({
'click .login-form-create-account #login-buttons-password': function() {
alert("I sent you an email to verify your account");
}
});
Unfortunately, that will still fire even if the user was not successfully created.
