Handy handlers for Meteor handlebars

#Handlebar-helpers Is a simple way of using sessions and collections in the Meteor handlebars template environment

Have a look at Live example

There are 4 simple handlers

• {{getSession}}
• {{sessionEquals}}
• {{find}}
• {{findOne}}

##How to use?

####1. Install:

    mrt add handlebar-helpers

Requires Meteorite get it at atmosphere.meteor.com

###Get session variable: The {{getSession 'foo'}} helper returns the value of session variable 'foo' In the template:

<h1>{{getSession 'foo'}}</h1>

In the controller:

  Session.set('foo', 'bar');

###Compare session to value: The {{sessionEquals 'foo' 'bar'}} compares session 'foo' value with the string value 'bar'. Can use ``integerandboolean``` values for comparing aswell. arrays and objects are invalids due to contrains in Meteor and handlebars

{{#if sessionEquals 'foo' 'bar'}}
  session 'foo' equals the value 'bar'
{{else}}
  session 'foo' doesn't equal the value 'bar'
{{/if}}

###Get data in from collection The {{find 'foo' '{}'}} and {{findOne 'foo' '{}'}} will return qurey '{}' result from collection defined as var foo = new Meteor.Collection("myFooCollection") From the demoHelpers example:

  {{#each find 'testCollection' '{}' '{ "sort": { "createdAt":1 } }'}}
    {{name}} - timeStamp: {{createdAt}}</br>
  {{else}}
    You never clicked the button
  {{/each}}

Note: query and options should be formatted as json, since attributes as Objects and Arrays aren't supported by the Meteor handlebars
