I found a way to skip before filters based on the format, as seen below, but I'm wondering if there is a better way since this clutters things and isn't very DRY.
before_filter do |controller|
:current_cart unless controller.request.format.js?
end
If I don't do this, json requests fail because the current_cart method, and other meth...
Hi all,
I'm having trouble getting my InventoryItem to accept nested attributes which is strange.
In my script/console, I did the following:
>> InventoryItem.create!(:name => 'what', :image_attributes => [ {:image => File.open("/home/davidc/Desktop/letterbx.jpg", "r") }])
ActiveRecord::UnknownAttributeError: unknown attribute: image_a...

def parent_method(opts={})
first = opts[:percent]
second = (10 * first).to_i

def second_method; return {:...

We are looking to shift to bundler for deploying internal applications. We currently use capistrano for deployment using git for SCM. After googling extensively, I have found about 20 different ways to incorporate bundler into a rails 2.3.x application - but much of that information is out of date.
currently we freeze gems to the appl...

I'm using some ruby code wrapped in a begin - rescue block but somehow it manages to still crash.
the block of code looks like this:

msg = @connection.uid_fetch(uid,'RFC822').first.attr['RFC822']

Am using RingyDingy.
Have altered call to Rinda::RingFinger.new to Rinda::RingFinger.new('localhost') in ring_server.rb and in ringy_dingy.rb, but still get, intermittently, attachments to like named services on my compatriots (in the same lan segment) which causes things to disappear trying to run on their machine (or on mine from the...
Quick question:
>> Group.first.resources.joins(:tags).group("tags.id").select("tags.id, count(*)")
=> [#<Resource id: 1>, #<Resource id: 2>, #<Resource id: 3>, #<Resource id: 4>, #<Resource id: 5>]
This results in the following (correct) query:
"SELECT tags.id, count(*) FROM "resources" INNER JOIN "taggings" ON "resources"."id" = "ta...
I'm moving back into full time web development after a 5 year hiatus. My previous experience (no active record or MVC) tells me to be very thorough with my database schema. Foreign key constraints, unique indexes, etc... can really help out when your writing spaghetti code.
Does the community still find these useful when working in an...
I have metal working (thanks to Railscasts), but I have a haml template that I want to render instead of just plain text. Apparently you can render ERB , but I don't see any place to do the same with haml. Is it possible or will I just have to live with using the plain rails routing if I want to continue using haml?
Thanks!

I want to render a form (fields and includes a submit button) when using link_to_remote -- the form appears via an ajax call.
I'd like that form to behave as any other form would (it's a basic New Active Record) form, nothing fancy.
Upon submit, though, I'd like the original parent page to remain static without refreshing and, instead ...

I have a new application starting that's using Rails 2.3.8 for stability concerns and gem compatibility, however we'd like to begin being conscious of Unobtrusive JavaScript by implementing the Rails 3 style UJS in this application. Is there any existing plugin/gem that backports this feature?

I have a many-to-many model, following the example in this great railscast
My model links authors to each other. I'd like to validate that an author cannot friend himself. I know I can handle this at the UI level, but I'd love to have a validation in place to prevent a bug in the UI from allowing it. I've tried validates_exclusion_of, b...
I am working with a third-party API. That server is supposed to POST back to my URL.
My URL is:

The controller has some logic, but basically contains a respond_to do block and the corresponding view is a very basic xml builder.
However, I get the following error in the logs:
