没有运行before_save

Question

I have a model with before_save :autofill_country_code which will fill missing values. However, when I run my rspec test, it doesn't seem to run the before_save.

I pried my test open and saving did not update the attributes.

How do I work around this?

it "should autofill country code" do
    empty_country_code = ''
    @store = Factory.build(:store, :country_code => empty_country_code)
    expect{ @store.save }.to change{ @store.country_code }.from('').to(1)
end

The following is my autofill code:

def autofill_country_code
  unless self.country_code.present?
    country = GeoCache.geocode(self.city).country_code
    country_code = IsoCountryCodes.find(country).calling
    self.country_code = country_code.tr('+', '')
  end
end

Answer 1

Do you have validation set up for country_code ? Hooks are performed in that order:

before_validation
after_validation
before_save
around_save
before_create
around_create
after_create
after_save

So if model is invalid, before_save hook will not be executed. Try before_validation :autofill_country_code instead.
