rails 3.1 asset pipeline

a quick look at app, lib, vendor and gem assets for rails 3.1 rc1

It is a pretty rough screen cast, but hopefully has some useful information for you

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.

UPDATE: see "Unholy Rails: External Scripts, jQuery Plugins, and Page-Specific JavaScript" for a detailed look at using the asset pipeline with rails.

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

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:

Fixing asp.net MVC AuthorizeAttribute

With very little code we can fix asp.net MVC AuthorizeAttribute
What problems does it have? Too much redirection.

  • When making ajax calls a HTTP 401 (Unauthorized) would be better than a redirection
  • If I am already logged in but access a secure resource (controller / action) redirecting to the login page is far from ideal, an access denied view makes more sense
When is the built in redirection appropriate? When making standard HTTP request and the user is not authenticated.

it turns out it is relatively easy to fix these issues
  • inherit AuthorizeAttribute
  • override HandleUnauthorizedRequest
#1: Ajax request should not return redirection / html response

if the user cannot authorize an action and the request is made via ajax we don't want 200 or 302 response codes

we do want 401 Unauthorized, but we have to settle for a 403 Forbidden

The code to fix this

#2: Authenticated users should not redirect to the login page, they should get an Access Denied page
The code to fix this

Turns out very little code is needed - but seems like some of this should just be built in? Using the 401 response won't work because the asp mvc framework must be picking that up later on and forcing the redirection to the login page, the 403 is not ideal but it is effective.

The code for our class - AuthorizeFor


Usage of our AuthorizeFor attribute
