How to have checkboxes prepopulated in an edit form?

I've googled the hell out of this one. I'm sure there's a way, possibly requiring some code inside a html options hash, but I can't work it out. Any ideas?

When visiting the _edit_word_form.html.erb partial for a Word that DOES have one or more categories, the Categories checkboxes are all unchecked, requiring the user to select them again, even if they don't want to change the Categories.

The text fields for the :title and :description ARE pre-populated (thankfully).

The form:

<%= form_for(@word) do %>

  <%= fields_for :word, @word do |word_form| %>
    <div class="field form-group">
      <%= word_form.label(:title, "Word:") %><br>
      <%= word_form.text_field(:title, id: "new_word", required: true, autofocus: true, class: "form-control") %>
    </div>

    <div class="field form-group">
      <%= word_form.label(:description, "Definition:") %><br>
      <%= word_form.text_area(:description, class: "form-control") %>
    </div>
  <% end %>


  <%= fields_for :category, @category do |category_form| %>
    <% if current_user.word_list.categories.count > 0 %>
      <div class="field form-group">
        <%= category_form.label(:title, "Choose from existing Categories:") %><br>
        <%= category_form.collection_check_boxes(:category_ids, current_user.word_list.categories.all, :id, :title) do |b| %>
          <%= b.label(class: "checkbox-inline") { b.check_box + b.text } %>
        <% end %>
      </div>
    <% end %>

    <h4>AND/OR...</h4>

    <div class="field form-group">
      <%= category_form.label(:title, "Create and Use a New Category:") %><br>
      <%= category_form.text_field(:title, class: "form-control") %>
    </div>
  <% end %>

  <div class="actions">
    <%= submit_tag("Update!", class: "btn btn-block btn-primary btn-lg") %>
  </div>
<% end %>

What does your controller look like? I'm thinking your issue might be there.
