accepts_nested_attributes: undefined method 'association'_attributes

I have 2 models Timesheet and TimeEntry:

class Timesheet < ActiveRecord::Base

attr_accessible :status, :user_id, :time_entries_attributes

has_many :time_entries, dependent: :destroy

accepts_nested_attributes_for :time_entries, :reject_if => proc { |attributes| attributes[‘worktime’].blank? }

end

class TimeEntry < ActiveRecord::Base

attr_accessible :task_id, :timesheet_id, :workdate, :worktime

belongs_to :timesheet

end

As explained in Rails API:


Using with attr_accessible

The use of attr_accessible can interfere with nested attributes if you’re not careful. For example, if the Member model above was using attr_accessible like this:

attr_accessible :name

You would need to modify it to look like this:

attr_accessible :name, :posts_attributes

If I try to do the same for my case with time_entries association:


irb(main):016:0> t = Timesheet.new

=> #<Timesheet id: nil, user_id: nil, status: nil, created_at: nil, updated_at: nil>

irb(main):017:0> t.time_entries_attributes

NoMethodError: undefined method `time_entries_attributes' for #<Timesheet:0x007fa8aee56e98>

It does not work. Any idea?

Thanks and regards

I'm not sure, but I think that you must use "build" method to create a TimeEntry associated to TimeSheet.

Sorry , but the question was not about how to create time_entries association but how to receive the association attributes. I believed that calling timesheet.time_entries_attributes will do that.
