undefined method ` =' for #<Agency id: nil, name: nil, ip_adress: nil> - ruby-on-rails

Question

I am writing some rspec tests on my app and there is a bug, it show me that error :
undefined method ` =' for #<Agency id: nil, name: nil, ip_adress: nil>
There is my tests :
require 'rails_helper'
RSpec.describe Agency, type: :model do
it "should create the agency if all fields are filled" do
expect(FactoryGirl.build(:agency)).to be_valid
end
it "should fail if name is missing" do
expect(FactoryGirl.build(:agency, name: nil)).to_not be_valid
end
it "should fail if ip_adress is missing" do
expect(FactoryGirl.build(:agency, ip_adress: nil)).to_not be_valid
end
it "should fail if there is a double name in db" do
agency = FactoryGirl.create(:agency)
expect(FactoryGirl.build(:agency, name: agency.name)).to_not be_valid
end
end
My agency model :
class Agency < ActiveRecord::Base
module Agencymod
attr_accessor :name, :ip_adress
end
has_many :users
has_many :incidents
has_many :field_agency_agencies, dependent: :destroy
has_many :field_agencies, through: :field_agency_agencies
# # Regexp for the postal code.
# cp_regexp = /\A((0[1-9])|([1-8][0-9])|(9[0-8])|(2A)|(2B))[0-9]{3}\z/
# # Regexp for email.
# email_regexp = /\A[a-zA-Z0-9._-]+#[a-z0-9._-]{2,}\.[a-z]{2,4}$\z/
# # Regexp for phone number.
# phone_regexp = /\A(0|\+33|0033)[1-9][0-9]{8}\z/
# # Regexp for ip address.
ip_regexp = /\A(?:(?:[1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}(?:[1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\z/
validates :name, presence: true,
uniqueness: { case_sensitive: false }, length: { in: 0..44 }
validates :ip_adress, presence: true, format: { with: ip_regexp }, length: { in: 0..49 }
end
And finally my factory :
factory :agency, class: Agency do |f|
f.name  { Faker::Address.city }
f.ip_adress "8.8.8.8"
end
It is the first time this error appear and when I have tested the user model it works very well...
Sorry for my poor english :)

Answer 1

Thanks to everyone post answer.
I've found the error it appear there are an space between the f.name and the { Faker::Address.city }
When I have removed it, it show me the same error but with undefined method'name='... so I writed the factory like that :
f.name Faker::Address.city
and it works very well ...
My others factories are writted as below :
factory :user do |f|
f.surname { Faker::Name.first_name }
f.name { Faker::Name.last_name }
f.pseudo { Faker::Internet.user_name }
f.password "password"
f.email { Faker::Internet.free_email }
f.type_user_id 23
f.agency_id 2
f.tel "0606060606"
f.ip_addr { Faker::Internet.ip_v4_address }
end
and are working well too ..
f.name "TEST" # That works !
f.name"TEST" # Works too
f.name Faker::Address.city # Works
f.name { Faker::Address.city } # Nope
Issue in gem ?
