Why aren't the :locals hash variables being passed in to a partial, when called from inside my rake
- by marshally
I need to render a bunch of painfully long running partials using a rake task.
When I try to pull the partial from a rake task, I get the dreaded "Called id for nil, which would mistakenly be 4" error, which usually means that my locals hash has not been properly set into the partial.
Here's the rake task (some variable names have been changed to protect the innocent):
namespace :precache do
desc "Precache stuff"
task :precache => :environment do
av = ActionView::Base.new(Rails::Configuration.new.view_path, {})
av.class_eval do
include ApplicationHelper
end
@user = User.find(21)
@rank = Rank.find(2)
data = av.render(:partial => "reports/listing", :locals => {:user => @user, :rank => @rank})
end
end
And this is the error that I am getting:
** Execute precache:precache
rake aborted!
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
