Building Assocation with multiple belong_tos

[Jarod Watkins]

Hello,

I have two models that look like the following:

ModelA:

  attr_accessible :date, ...

  has_many :modelb

  accepts_nested_attributes_for :modelb

end

ModelB:

  attr_accessible :date, ...

  belongs_to :modela, :modelc, :modeld

end

And then in ModelAs controller:

@modela = Modela.new

3.times do |i|

  @modela.modelb.build(:date => Time.now)

end

When ModelB has 3 belongs_to and I attempt to build the association with just ModelA I get the following error:

ArgumentError wrong number of arguments (3 for 2)

When ModelB just belongs_to modela it works. Do I need to somehow setup a fake association for the other belong_tos? Those are to be created in the UI by the user.

Thanks,

Jarod

That should be modelbs, plural.

I think you have to specify those on separate lines.
