i am experimenting to use permalink\_fu to provide clean urls. To begin  
with, I have installed it and made necessary changes to models, routes  
etc. As I have existing records in table, I wanted to update its  
permalink column. So in console, I gave

Category.find(:all).each(&:save) --as specified by some article

permalink column gets updated with some crypted like string, like the  
ones given below.

url links use this as in

[domain.com/category/8012221562396cf8562fa4bf6b12d0a0ba23d528](http://domain.com/category/8012221562396cf8562fa4bf6b12d0a0ba23d528)

any help is highly appreciated.

No one can really help you without looking at your code.

The question is not about my code. Its about how to use permalink\_fu to  
an existing project.

More specifically, how to update existing models ( updating permalink\_fu  
column for the existing records )

have you used permalink\_fu before?.
