Change Bit Value To Text When Viewed
Hey All, very simple question for you folks ;) I have a @commutes object that for each record there is a bit value set (0/1) to denote if an accident occurred. What I want to do is have it display "Yes" or "No" when I view the listing of commutes. I can get it to display the bit value just fine with <%= commute.accident %> but how can I get it so that when a record with

Converting HTML into an Image
I have this challenge of converting a bit of html into an image file and then shrinking it into a thumbnail. The shrinking part shouldn''t be too bad, but what advice can you give on converting the html to the image? My thinking is that I will need to convert it to postscript or latex and then convert it to an image from there. Is there an easier / better approach? Michael

file and directory layout below app/models
Hiall, Is it possible to organize my model files below app/models into subfolders? E.g. I would like to put admin related models into their own subfolder. This kind of structuring works for controllers and views (scaffolding creates the right subfolder-model mappings), but app/models always stays flat. I''d really like to be able to group my code into logical, well packages :-) Yes, I

link_to_remote doubles border size
I have a div with a border around it. I use link_to_remote to change the content, and the border size doubles.

collection_select default selected value
Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

Named link to image
Hiall, Call me stupid if you like .,) but it seems i can''t figure out how to get a named link using a combination of link_to and image_tag. What I need is basically a link displaying a name along with some image to indicate status (open,working,finished). I found no combination of link_to and image_tag that accepts a name, this seems to be solely used for making whole images into links

Requiring /lib files in a cross-platform way.
Hi. When you have library foo.rb in your Rails project /lib directory, I notice that on some platforms - e.g. Windows with WEBrick as a server - you can require it by simply: require ''lib/foo'' However on other platforms - e.g. Debian with Lighttpd server via FastCGI - this does not work, and you need to specify RAILS_ROOT explicitly, like this: require

Native erb lacks -%>, where is Rails'' erb?
Native ERB in ruby, and eruby, seem to lack the -%> feature for suppressing trailing newlines. Thus erb -n script gives errors. Where is Rails ERB so I can invoke it directly? Thank you Hugh
