Hi Everyone,

I have four problems which I haven’t been able to solve for a while,  
and would appreciate any help:

1. Autocomplete question:  
I moved an application I started in Rails 1.0 ([rriki.sf.net](http://rriki.sf.net)) to Rails  
2.0 by looking at all the deprecated warnings. I no longer have the  
deprecated warnings, but auto complete no longer works. I installed  
the plugin, but it still does not work. ANY pointer as to how to get  
it working will be helpful.

2. Cross-platform question  
I generated the scaffold on a windows machine. I was really happy to  
see that the same exact code worked on Mac OS X without any  
alteration, right off the bat. Go Ruby!

However as I was fiddling with autocomplete installation I realized  
that the scripts had been coded to invoke ruby the windows way (e.g. c:  
\Programs\ruby) rather than the linux way (/usr/bin/env ruby) which  
was an easy fix:

Is there a way to convert a windows generated project so it will work  
in linux?

1. Directory access question  
Is there a way for the application to serve up files that exist out  
side the folder tree of the app?  
I use the app to access papers in pdf format and right now I have  
stored the pdfs inside the source tree, making it inelegant: my  
research papers are mixed in with the source code of my reference  
manager (rriki) and I find that not so good.

2. Database migration  
I started off using MySQL. I think however, I would like to use  
sqlite-3 and store the database outside the source tree, along with my  
research documents.

Does any one know of a proper way to move all the data in a MySQL  
database into a sqlite-3 database?

Many, many thanks to anyone who can help be a little bit with these  
things.
