Question

I get the following error message for the code below:

 Failure/Error: @league.errors.on(:short_name).should_equal "can't be blank"
 NoMethodError:
   undefined method `on' for #<ActiveModel::Errors:0x000001017853f0>


@league.errors.on(:short_name).should_equal "can't be blank"

According to several documentation references that I am reading, this should work. Any idea what’s going on?

Answer 1

Since @location.errors is a hash:

require 'rspec'

describe "Location" do
  before(:each) do
    @location = double("Location")
    @location.stub(:errors).and_return(:short_name => "can't be blank")
  end

  it "should work like a hash" do
    @location.errors[:short_name].should == "can't be blank"
  end
end
