How can I get values for multiple data parameters in the routes of Meteor iron routers?
I have the following route defined for my small Meteor application:
this.route('browse-class', {
path: '/browse/:_class',
data: {
theClass: function() { return this.params._class; },
numBooks: function() { return Books.find({"class": this.params._class},{sort:{"createdAt": 1}}).count(); },
books: function() { return Books.find({"class": this.params._class},{sort:{"createdAt": 1}}); }
}
});
I am not accessing the returned data values. Namely numBooks. It should return an integer, but I can't get it to behave with the following code in my template helper:
Template.browseClass.helpers({
booksFound: function() {
return this.data.numBooks > 0;
},
theOwner: function() {
theUser = Meteor.users.findOne({_id: this.owner});
return theUser.username;
}
});
When I console.log () the value I am comparing, it seems like it is trying to compare a function instead of a return value or something? I was a little confused.
Any thoughts would be much appreciated. Thank!

the data should be defined as a function in your route like this:
data:function(){
var booksCursor=Books.find(...);
return {
theClass:this.params._class,
numBooks:booksCursor.count(),
books:booksCursor
};
}
Then, if you specified browseClass
a route as the template, it will be displayed with the result data()
as the data context, so you can access the following properties:
Template.browseClass.helpers({
booksFound:function(){
return this.numBooks>0;
}
});
<template name="browseClass">
Number of books : {{numBooks}}
{{#each books}}
{{...}}
{{/each}}
</template>
