Hi,

I have a has\_many association between Book and Page.

I have acts\_as\_ferret running on only the Book model. However, when I  
update the a page, it calls the auto update index on the Book model as  
well just in case any of the ferret fields were changed.

How can I stop acts\_as\_ferret from auto updating the index on its own,  
especially when nothing changes?

the book index will only be updated if a book record is saved. To save a  
book record without updating the ferret index, look at the  
ferret\_disable method aaf mixes into your book model, or into the wiki:  
[http://projects.jkraemer.net/acts\_as\_ferret/wiki/AdvancedUsage#Disablingautomaticindexing](http://projects.jkraemer.net/acts_as_ferret/wiki/AdvancedUsage#Disablingautomaticindexing)

As an alternative, If you want a completely custom handling of when aaf  
does automatic index updates and when not, just override the  
ferret\_enabled? instance method in your book model to return true only  
if you want automatic indexing and false otherwise.
