Let's say we have a hash: flash = {} flash[:error] = "This is an error." flash[:info] = "This is an information." I would like to convert it to a string: "<div class='error'>This is an error.</div><div class='info'>This is an information". in nice one liner ;) I found something like that: flash.to_a.collect{|item| "<div class='#{...
Rails' ActiveRecord::Base class defines an == method that returns true if the objects are identical or they have the same ID. I've overridden == in a couple of my Rails models to allow for more meaningful equality conditions. These work when I compare objects directly (e.g., through script/console), but if I do something like my_array_o...

I'm using rcov on a set of tests autogenerated from my rails routes to collect information on dead code (code which is never called in the application). This set up already generates enlightening results for controllers, models, helpers, and lib code. Unfortunately rcov does not track code coverage in erb templates, which makes sense a...

I have a program that looks like: $offset = Point.new(100, 200); def draw(point) pointNew = $offset + point; drawAbsolute(point) end draw(Point.new(3, 4)); the use of $offset seems a bit weird. In C, if we define something outside of any function, it is a global variable automatically. I wonder why in Ruby, it has to be $offse...

I'd like to write a Rake task that will load some development data for my app so I can see what the design looks like in the browser with some data populated in there. I've tried hacking together something using ActiveRecord and the Faker gem, but I'm having a hard time keeping it simple and practical. It quickly turns unwieldy. Problem...

I was wondering how some of you overcame this obstacle? How did you stop thinking relationally and start think documentally (I apologise for making up that word). Any suggest...

I'm trying to use fixtures to add more complex test data in order to test specific scenarios with the front-end, which is in Flex. I'm not sure this is the right way to go about it with rails. My rails app is a card game and the 'more complex test data' I'm trying to test are various combinations of cards. For example, I want to set up ...
I set up hoptoad on my prod server and ran rake hoptoad:test. I get the notifier in my hoptoad interface so it seems to work great. But then I forgot to migrate my database after my last deploy so I got a "ActionView::TemplateError" in my production log. This caused a 500 so I feel like HopToad should have notified me about this. Hav...

I 've researched and noticed that ActiveResource lack this functionality. So, what is the current state of the art when doing a file upload? One problem with Guillermo's approach is that the request has to be nested, like this: body = { :file => {:uploaded_data => File.open("#{RAILS_ROOT}/public/tmp/" + original_filename), :owner_id =>...
