I have a model “Chapter”  
I figured out how to add assets to chapter through papermill plugin.  
Now the question:  
how can i add additional description to each asset?

It can look like:  
chapter has\_many items  
item belongs\_to chapter  
item has\_one papermill\_asset  
papermill\_asset belongs\_to item

But i don’t know how to build models and view for described scheme.

How can I add new line in “intem” table then papermill creats new one  
in papermill\_assets?

Or may be you know the true way to solve this problem?

Any help?

Thx.
