Ruby on Rails

I'm working on a project that has the following setup

I have a table called Assessment

for each assessment there can be different reasons and consequences defined for that assessment

then for each assessment the teacher takes multiple data entries over a period of time

each data entry can choose multiple reasons and consequences from the ones defined in the assessment

So you have assessment

has_many :reasons

accepts_nested_attributes_for :reasons

has_many :consequences

accepts_nested_attributes_for :consequences

has_many :data_entries

accepts_nested_attributes_for :data_entries

Then reasons

belongs_to :assessment

has_and_belongs_to_many :data_entries

Then consequences

belongs_to :assessment

has_and_belongs_to_many :data_entries

Finally data_entries

belong to assessment

has_and_belongs_to_many :reasons

has_and_belongs_to_many :consequences

There is also a join table for reasons to data_entries, and consequences to data_entries

The nested table works fine for the reasons, consequences, and the base data_entries

however what I cannot get to work is the reasons and consequences chosen in the data_entries

what appears to be happening in params is that assessment comes back with data_entries_attributes under it

however there is also a data_entry param coming back as well, so it is not part of assessment, so the nest is wrong somehow...

I have this working in other places however this nest is one level deeper than the others...

The way I have the nested form section setup is this...

  <td>

    <div class="multi-column">

      <ul>

        <% @assessment.reasons.each do |reason| -%>

            <ul>

              <%= check_box_tag('data_entry[reason_ids][]', reason.id, @assessment.reason_ids.include?(reason.id), :multiple => true) %>

              <span rel="tooltip" title="<%= reason.assessment_id %>"><%= reason.name %></span>

            </ul>

        <% end %>

      </ul>

    </div>

  </td>

  <td>

    <div class="multi-column">

      <ul>

        <% @assessment.consequences.each do |consequence| -%>

            <ul>

              <%= check_box_tag('data_entry[consequence_ids][]', consequence.id, @assessment.consequence_ids.include?(consequence.id), :multiple => true) %>

              <span rel="tooltip" title="<%= consequence.assessment_id %>"><%= consequence.name %></span>

            </ul>

        <% end %>

      </ul>

    </div>

  </td>
