This seems like a noob question, but the simple answer is eluding me. I need to call link_to in an ActionController method to spit out an HTML link. ActionView::Helpers::UrlHelper.link_to calls url_for, but this calls the AV module's version instead of the controller's. I managed to coerce this into doing what I intended by putting #...

Anemone.crawl(start_url) do |anemone| tentacle.new(i think but not working) anemone.on_every_page do |page| puts page.depth puts page.url e...

So, if I have a polymorphic association throughout my application, is there a way to add methods to it? For instance, if :post, :photo and :user are all associated to :rankings with a polymorphic association named :rankable, can I somehow create methods on :rankable that would then be inherited by :post, :photo or :user? My guess is th...
I'm currently using GEdit with several plugins to do Ruby on Rails development. One thing I would like to have is a way to automatically format my source files (.rb, .*.erb, etc.) Ideally it would be something that I could call from the command line and/or GEdit. Command line tool would be nice, because I can set up a Git hook to auto-...

After following the instructions several times for generating an SSH key (http://help.github.com/mac-key-setup) and testing "ssh git@githu...
What I know: Rails has the cycle() method that enables odd/even rows in a table to have different CSS classes. We can pass multiple classes to the cycle() method and that works great. I wanted rows which are grouped in three's; so, I used this: ...some html-table code... <tr class="<%= cycle("table_row_1","table_row_2","table_row_3","...

My server keeps crashing. It is especially bad in localized parts of my app where the rest is fine. On one major page it is now happening every time.
