Rails 中的 ArgumentError（arguments 的编号错误（给定 5，预期为 1））

Question

I have a Scaffold called contracts and a Model called Addresses. I want to add call my model in the scaffold. in the Contrato.rb (Model) I have:

class Contrato < ApplicationRecord
  has_many :addresses
  accepts_nested_attributes_for :addresses, reject_if: lambda { |attrs| attrs['estado', 'cidade', 'bairro', 'endereco', 'cep'].blank?}

  before_save do
    self.paf.gsub!(/[\[\]\"]/, "") if attribute_present?("paf")
  end
end

When I try to create a Contract using the console using: Contrato.create:(razao, "Carrefour Comercial": cpnj, "12141618": insc_estadual, "12345": insc_municipal, "56789": paf, "": empresa, "Carrefour": addresses_attributes:[{estado, "Sc": cidade, "santos": bairro, "myborough": endereco, "avenue": cep: "112233"}) The rails controller returns:

Traceback (most recent call last):
        2: from (irb):8
        1: from app/models/contrato.rb:3:in `block in <class:Contrato>'
ArgumentError (wrong number of arguments (given 5, expected 1))

I'm clueless about this error.

Answer 1

I solved adding

def contrato_params
      params.require(:contrato).permit(:razao, :cpnj, :insc_estadual,:insc_municipal, :empresa, paf:[], addresses_attributes:[:estado, :cidade, :bairro, :endereco, :cep])
end

The addresses_attributes to the contracts controller.

Answer 2

In above code

class Contrato < ApplicationRecord
  has_many :addresses
  accepts_nested_attributes_for :addresses, reject_if: lambda { |attrs| attrs['estado', 'cidade', 'bairro', 'endereco', 'cep'].blank?}

  before_save do
    self.paf.gsub!(/[\[\]\"]/, "") if attribute_present?("paf")
  end
end

At line of accepts_nested_attributes_for it should be like

  accepts_nested_attributes_for :addresses, reject_if: lambda { |attrs| attrs.any? { |k, v| ['estado', 'cidade', 'bairro', 'endereco', 'cep'].include?(k) && v.blank? } }
