I have a relational association like this one
<pre><code>class Person
include Mongoid::Document
references_one :policy
end

class Policy
include Mongoid::Document
referenced_in :person
end
</code></pre>
And in my capture form I do something like this:

<pre><code>.field
= f.label :policy
= f.select :policy, Policy.find(:all).collect

</code></pre>
and I get this error on updating:
<pre><code>undefined method `associations' for "4ca2cd498886c1205d000001":String
</code></pre>
any thoughts?
