Rails test validates_associated on model spec

Question

Is there an equivalent to

  it { should validate...


  it { should validate_uniqueness_of(

etc for

 validates_associated

Something like,

it { should validate_associate(:associated_model_object)

except, you know, functional.

Thanks!

Answer 1

I think something like this would work:

it "should validate associate_model_object" do
  m = Model.new(valid_params)
  m.associated_models.build(invalid_params)
  m.save.should eq(false)
end

Replace the middle line with this if you're coming from the other direction:

m.build_associated_model(invalid_params)
