I am quite new to ruby on rails so bare with me.

I just got an interesting repository from github and I have been trying  
diligently to get this app to work. This seems like a general error to  
me but I do not understand how to fix it.

If some one could help I would definately appreciate it

Thanks.

There are much, much better ways to learn Rails than finding interesting  
GitHub  
projects. GitHub contains many jewels, and it is also nothing but a big  
backup  
server. Don’t expect every project there to be fully productized!

For example, when I tried “magic\_the\_gathering”, I could not get past  
this:

$ rake db:migrate:reset  
…  
undefined method `files’ for ImportCards:Module

Now notice that all the files have the same times stamp, I suspect from  
last  
year, and all the files have only one version, so maybe we are looking  
at  
something that someone got working on their own desktop (with a stray  
‘files’  
field in their database!) and then tossed onto GitHub and never got back  
to!

Ask the author if she or he wants to return to this project…
