我在Heroku的Rails 3.1.3上遇到了这个rake任务的问题：
task :update => :environment do
# Get the Assignments
@a = Assignment.all
# Change the dates
for a in @a
a.new_start_date = a.start_due if a.a.new_start_date.nil?
a.new_due_date = a.due_date if a.a.new_due_date.nil?
a.description =+ "This assignments was edited by an update task. This task updated the due date.
This action was taken by our auto-updateder at #{Time.now.utc} UTC. If you
have questions please contact support. This update
was started by CEO, XA." if a.a.new_due_date.nil?
a.save!
end
end
我收到了这个错误：
Running rake update:duedate:update attached to terminal... up, run.1
fatal: Not a git repository (or any of the parent directories): .git
rake aborted!
uninitialized constant Object::Assignment
Tasks: TOP => update:duedate:update
(See full trace by running task with --trace)
这是跟踪：
