[Rubycocoa-talk] Custom ActiveRecord::Base-methods and Bindings

[Pim S. <pi...@li...>]

Hello,

Again a bindings question, sorry for asking so many questions. I hope  
I can answer some when I get more experienced.

I have the following ActiveRecord class:

class Issue < ActiveRecord::Base

	belongs_to :project
	has_many :time_entries, :dependent => :delete_all

	def spent_hours
		@spent_hours ||= time_entries.sum(:hours) || 0 #its a float
	end
end

If I retrieve spent_hours manually in de code like below it works as  
it should;

@issues = Issue.find(:all)
@issues.each do |issue|
	if issue.spent_hours >0
	puts issue.spent_hours.to_s
	end
end

but in the NIB where I have set the Model Key Path of a table column  
to "spent_hours" it stays empty. Must I add some magick to the  
IssueProxy e.g. with on_get?

Regards,
Pim Snel
