Support for multiparameter attribute assignment on virtual attribute writers

This bit us today too. The fallback to time is a real nice way to handle this IMHO.

This bit me too.

Couldn't you use composed_of instead of attr_accessor here? That'll give you the necessary bits to make this work?

Time seems like a nice format but it's a little magical here?

I'm not quite sure why this was assigned to me.

If it was because of the composed_of replacement that I wrote in the past; Manfred has taken another stab at it: #950 AttributeDecorator, a new take on aggregation.

I'm just not sold that a default of Time makes sense. The multi
parameter code handles more than just Dates and Times and you can tell
it what the type is by specifying composed_of or something similar.

I'd prefer to fix it 'right' rather than just default to time if we're
unsure. Perhaps the best way to do this is to make sure that #950 AttributeDecorator, a new take on aggregation. has
something simple for this case?

Would be great to get this fixed. In the meantime, I thought I'd drop in and say that I found a very hack solution:

class Whatever < ActiveRecord::Base
  ...
  
  attr_accessor :arrival_time
  columns_hash["arrival_time"] = ActiveRecord::ConnectionAdapters::PostgreSQLColumn.new("arrival_time", nil, "time")
end

Obviously will need some adaptation depending on the database used etc.

Correcting Jon Leighton:

class Whatever < ActiveRecord::Base
  ...
  
  attr_accessor :arrival_time
  columns_hash["arrival_time"] = ActiveRecord::ConnectionAdapters::Column.new("arrival_time", nil, "time")
end

The above code fixed it for me. Of course, this is an ugly hack. Hoping for a fix soon.

ouch! bitten also.

I tried the above fix added by "felipekk"
but didn't work

here is my code

Mobile = Struct.new(:mobile_country_code, :mobile_pure_number)
class User
    attr_accessor :mobile_country_code, :mobile_pure_number
    columns_hash["mobile_country_code"] = ActiveRecord::ConnectionAdapters::Column.new("mobile_country_code", nil, "character varying(255)")
    columns_hash["mobile_pure_number"] = ActiveRecord::ConnectionAdapters::Column.new("mobile_pure_number", nil, "character varying(255)")
    composed_of :mobile,
                :class_name => 'Mobile',
                :mapping => [%w(mobile_country_code mobile_country_code), %w(mobile_pure_number mobile_pure_number)],
                :constructor => Proc.new { |mobile_country_code, mobile_pure_number|
                  Mobile.new(mobile_country_code.to_s.gsub(/^\+/, '00'), mobile_pure_number)
                }
end

when i try this code in console

u = User.new(:mobile_pure_number => '123491484', :mobile_country_code => '0020') ; puts u.mobile.mobile_pure_number

i get nil

any clue ??

Any updates here? This is still an issue?
