Hello all,

I use community engine in my web application.  
when I create a new application and integrate CE it works perfect.  
But when i integrate CE in my application it is not working.

please give suggestions.

My problem is that --------

my application has database “aflatune\_development” . I setup CE in my  
application as per instruction given at “[http://communityengine.org/](http://communityengine.org/)  
documentation.html”.  
It create migration file in my “db/migrate/  
20090408130952\_community\_engine\_to\_version\_61.rb”

Before this my database contains two tables “roles” and “users” which  
are also present in CE  
so i renamed my these two tables first and then tried.

when I execute migration using rake db:migrate,  
It executes some migration and then throws error that

rake aborted!  
An error has occurred, all later migrations canceled:

following is some executed migration and error

# == CreateFavoritables: migrating
