Sharing code between validation functions for different views.

[macario <ma...@gmail.com>]

I am toying with document validation and I would like not to repeat the same
validation functions on each validate_doc_update,
I've read that validate_doc_update for each view are ran in an order given
by couchdb, so is there any way I can load some functions before the whole
validation process?

Do you mean validate_doc_update for each design document (each design
document can include multiple views). You can't run a function before  
any
one validation function. If we had a "pre_update_validate" hook, it'd  
need
guaranteed execution order and if we'd want that we could add it for  
regular
validation functions as well. As fast as sharing code, you can use  
CouchApp's*
library feature, where your code only lives in one place when you  
develop,
but gets copied when pushed to CouchDB.
