Re: [Myexperiment-discuss] Get credits and tags

[Jiten Bhagat]

Hi Tony,

To get a list (ie: array) of creditors name (I'm assuming you don't want 
*usernames* and you want just the names of users who have been credited, 
not groups):

credits_names = workflow.creditors.map{|c| c.creditor.name if 
c.creditor_type == 'User'}.compact

The reason for the "c.creditor_type == 'User'" and the ".compact" is to 
get rid of groups in the list. If you want groups as well then do:

credits_names = workflow.creditors.map{|c| c.creditor.contributor_label}


For tags do:

tags = workflow.tags.collect{|t| t.name}


We've been putting together more information about the myExperiment 
codebase here: http://wiki.myexperiment.org/index.php/Developer:Docs. 
You could take a look there, as a start and if you have detailed 
questions let us know.

Cheers,
Jits
