Act as Taggable Steroid Problems when Adding Column

I used pluggin Act as Taggable Steroid to create Tag

In the table Tag,by default, There are only Tag and name.

I have added column user_id to make personal tag(each user have their
own tag).

This is the old code to add tag by using Act as Taggable Steroid.

@company.tag_list.add(params[:tag][:name])

The problem is ... i don't know how to add user_id in tag column since i
don't find the way to modify it to do so.
