Let\'s say I have a todo app, and I want to make sure that every user that registers has at least one todo to start with, something like \"First todo to cross off!\", how wo

Basically, right now, there is no createUser hook when using accounts-ui, only when programmatically doing so via Accounts.createUser
. Also, there are no hooks for login, unless using the lower-level login functions like loginWithFacebook
, etc. I haven't figured out an ideal way around this yet, but a few ways of handling it:
if needing to enter a default value into a collection, in that collection's subscription, use the onComplete argument. In this callback, if there are no entries in collection, add one. This avoids the first problem I mentioned in my post about not knowing when a collection was loaded, though not ideal since collection could be empty because user already removed first default one:
Meteor.subscribe 'todos', user: Meteor.userId(), () ->
todo = Todos.findOne()
unless todo
Todos.insert user: Meteor.userId()
you can set up a login hook by using the Meteor.autorun
reactive method to check for a change in Meteor.userId(). That'll only get called when the user logs in/reloads the page. This is more useful for non-collection stuff since the collection is not guaranteed to be loaded when Meteor.userId is set:
Meteor.autorun () ->
if Meteor.userId()
console.log 'Do some post login hook'
So I think the efficient solution is still out there somewhere, but wanted to update this post with workarounds I had found in the meantime.
