Basic idea:

View:

<%= form_tag({:action => ''update'', :id => @document})
%>

<%collection_select(:document, :dependent_id, Dependent.find(:all), :id,
:name)
%>

<%= submit_tag ''Commit'' %>

(The form triggers the ''update'' method, storing your
@document.id in
params[:id]. The value that is selected by the user in the drop-down
box will be stored in params[:document][:dependent_id])

Controller

def update
     @document = Document.find(params[:id])
     @document.update_attributes(params[:document])
     # this line will update each attribute of @document with the
corresponding attribute in params[:document]. In this case, it''s the
same as if you did: @document.dependent_id params[:document][:dependent_id] and
then @document.save.
end

This example stores the dependent_id rather than the dependant_name,
but that''s what you should store. Then in your Document model you
should have:

belongs_to :dependents

and in your Dependent model

has_many :documents

Then you can view the name of the dependent for any document like this:

@document.dependent.name
