[Rails] Re: Stop using Foo Bar!

Foo and Bar are the conceptual equivalent of using lorem ipsum when designing web pages. They're obviously not real things and so don't distract the user's attention away from the bigger picture. I do agree with some people here who've pointed out that as soon as variables hold something meani

[Rails] Intermediate level tutorials

Hi I'm hoping somebody can suggest an intermediate level tutorial or point me in the right direction. I'm a moderately experienced programmer (20 + years off and on) but I'm really struggling to get to grips with Web/RoR development. I'm reasonably familiar with Python and am getting familiar with

Re: [Rails] Stop using Foo Bar!

Part of the problem with more 'realistic' variable names is that some people will fixate on the names and fail to notice the general principal. For example def has_min_elements?(foo, bar) foo.size >= bar end might be harder to read for someone new but def bookshelf_has_at_least(bookshelf, numb

[Rails] Re: Stop using Foo Bar!

I just don't see the point in adding an extra layer of abstraction where there doesn't need to be one... Most RoR evangelists go on about the readability of the code, so why spoil it by putting gibberish in? If you're going to the effort of trying to explain something to someone, why not make

My bet is that you're environment doesn't have a `rails` binary and it is finding the first one it can, which happens to be 1.9.1. Does the same thing happen when you do: ∴ ./script/rails server Which will be sure to use the Rails version bundler bundled for the app with the current Ruby? You c

You can always use Voo, Doo, and Vlad. Metasyntactic variables are not meant to be creative or original though. They are simply meant to represent unknown variables. The common ones are Foo, Bar, and Baz. -- You received this message because you are subscribed to the Google Groups "Ruby on Ra

[Rails] utf-8 htmlentities,decode keeps switching to ascii-8bit

Hi there, it's not really rubyonrails but because it fits into the web-development I think I'm in the right forum. I'm trying to decode a string I read from an online xml-file and compare it to another, locally stored one. The locally stored string is: p localstring #=> "~St0rm€lite~" p localstri

[Rails] WEBrick won't use correct Ruby version with RVM

Ok, so I realised the hard way that 1.9.1 is just too close to the edge, especially in combination with Rails 3. I installed RVM and 1.8.7 which seems to work, but whenever I start WEBrick it still insists on using 1.9.1 which causes all sorts of strange problems and exceptions. b...@silicon:~/rai
