In my app I use accounts-github
. Works perfect, but I have one problem.
In one of my templates I do
Template.bar.rendered = function () {
if (Meteor.user()) {
// setup stuff
}
}
The problem is that if the user initially is not logged in this code is not executed (thats ok). But when the user authenticates this code is not executed again. So the question is how can I listen for this change inside a template (doesn't have to be in inside the rendered
function!)?
You could use Deps.autorun
. ( http://docs.meteor.com/#deps_autorun )
Usually Deps.autorun
would run for your whole Meteor app. If you want to make it so that it only runs per template you would need to create and stop it in the rendered and destroyed template callbacks
eg
var loginRun;
Template.bar.rendered = function() {
loginRun = Deps.autorun(function() {
if(Meteor.user()) {
//Stuff to run when logged in
}
});
}
Template.bar.destroyed = function() {
loginRun.stop();
}
If you don't need it to run per template (need it to run just once for you app on any template, then you can use the Deps.autorun
on its own, anywhere in your client side code.
Meteor.user()
is reactive, it would ensure that the Deps.autorun callback runs again when it changes, so you could theoretically use it to do things when the user logs in or out.
Other alternatives is there is a package on atmosphere that provides login and logout hooks, though they basically would use the Deps.autorun like above to work anyway. See https://github.com/BenjaminRH/meteor-event-hooks
My solution for similar problem was to
Template.bar.rendered
is called Eg
Template.bar.events({
'click .loginButton' : function() {
if( Meteor.call.Login( username, pw ) )
{
$('#bar').html( Meteor.render( Template.bar ));
//jQuery is optional
}
});
