rails 3.1 javascript execution

Looking at a few different ways to execute javascript in rails 3.1. By default all javascript is compiled into one file and embedded in anonymous functions which all execute on each page.

We often want to be selective in how our javascript executes, based on controller and actions. We look at 3 different approaches

• use selectors based on form id
• use selectors based on css classes on the body
• namespaced javascript objects

if you know of any other approaches I would love to hear those as well

I recommend you click the HD link on the player and view it on Vimeo in full screen mode, this embed version is not so crisp.

AT&T site has some serious issues

I went to check on the price of DSL, I've been a long time Comcast customer and getting tired of the high cost. So I went to check it out on AT&T - all I can say is WTF?

Select 'DSL without phone', but then my choices are everything except what I am looking for?
I think they need to go back and do some more QA

Now I get to choose my phone service - WTF: I selected 'without phone service' for a reason

Simple.Data and MongoDB

Get really dynamic with Simple.Data and MongoDB

took me awhile to figure out the proper way to establish a connection with Simple.Data.MongoDB




Resources

• MongoDB download
• Simple.Data
• Simple.Data.MongoDB
• Mongo and C#

You can install all of the dlls using Nuget, search for Simple.Data.MongoDB and install that package it will bring in the rest

Some of the errors I received on my journey

From Simple.Data

Message=No valid exports were found that match the constraint '((exportDefinition.ContractName == "Ado") AndAlso (exportDefinition.Metadata.ContainsKey("ExportTypeIdentity") AndAlso "Simple.Data.Adapter".Equals(exportDefinition.Metadata.get_Item("ExportTypeIdentity"))))', invalid exports may have been rejected.

And from mongo driver when my connection string was not in the correct format, I was using the wrong port

Message=No connection could be made because the target machine actively refused it 127.0.0.1:
