Question

How does one write a Factory Girl definition for a Mongoid class where one of the properties is a hash? (it is not an embedded document)

The Mongoid class looks something such as

class Foo
  field :bar, :type => Hash
end

so an instance of Foo should be able to access bar via foo.bar['foobar'] = 1

This cannot be depicted in a Factory Girl definition though by doing something like:

Factory.define :foo do |f|
  f.bar   {:foobar => 1}
end

Answer 1

I don’t know FactoryGirl, but I’d guess that Ruby is interpreting the curly brackets as a block. This should work:

Factory.define :foo do |f|
  f.bar({:foobar => 1})
end
