Is it possible to use methods for migration(create\_table, add\_column,  
etc) in applications.

I want to make a plugin which uses its own model. In such cases, most  
plugins seem to use script/generate to generate migration file. But I  
think if it is possible to make tables directly from plugins, uses  
doesn’t have to use script/generate or rake. It’ll be easier to use.  
But I couldn’t find how to do it.

Any help appreciated.
