I created a little example for myself to test some stuff with Meteor. But right now it looks like I can't subscribe to a collection, I published on the server side. I hope somebody can tell me where the bug is. server/model.js <pre><code>Test = new Meteor.Collection("test"); if (Test.find().count() < 1) { Test.insert({id: 1, name: "test1"}); Test.insert({id: 2, name: "test2"}); } Meteor.publish('test', function () { return Test.find(); }); </code></pre> client/test.js <pre><code>Meteor.subscribe("test"); Test = new Meteor.Collection("test"); Template.hello.test = function () { console.log(Test.find().count());//returns 0 return Test.findOne(); } Template.hello.events = { 'click input' : function () { // template data, if any, is available in 'this' if (typeof console !== 'undefined') console.log("You pressed the button"); } }; </code></pre> client/test.html <pre><code><head> <title>test</title> </head> <body> {{> hello}} </body> <template name="hello"> <h1>Hello World!</h1> {{#with test}} ID: {{id}} Name: {{name}} {{/with}} <input type="button" value="Click" /> </template> </code></pre> EDIT 1 I want to change the object test, findOne() returns. Let's say for adding an attribute avg which contains the average value of two numbers (test.number1 and test.number2). In my opinion this should look like the following code. But javascript is not synchronous, so this won't work. <pre><code>Template.hello.test = function () { var test = Test.findOne(); test.avg = (test.number1 + test.number2) / 2; return test; } </code></pre> EDIT 2 This code worked for me. Now I have to rethink why this solution with 'if (test)' just works with findOne() without a selector in my original project. <pre><code>Template.hello.test = function () { var avg = 0, total = 0, cursor = Test.find(), count = cursor.count(); cursor.forEach(function(e) { total += e.number; }); avg = total / count; var test = Test.findOne({id: 1}); if (test) { test.avg = avg; } return test; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
