I've managed to find a workaround to this now. The index action now has an "order" clause before the call to page and the meals are then sorted and grouped by date. The hackey bit next: @total\_pages and @pages are used in the view to provide pagination links as the built-in helper for this does not work with the Hash of arrays as returned by @meals. It works (kind of) but it is hackey. Moving the view stuff into a helper would definitely help clean it up, which is my next step.

```
def index
  @meals = Meal.order('date DESC').page(params[:page]).text_search(params[:query]).sort_by(&:date).reverse.group_by(&:date)
  @total_pages = (Meal.all.size / 7.to_f).ceil
  @pages = (1..@total_pages).to_a 
respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @meals }
end

```

end

I really need help on this - it's been driving me mad for a couple of days. I am trying to paginate a hash of arrays. I have tried both will\_paginate and Kaminari, but cannot find a way to paginate the resulting hash.

I'm running Rails 3.2.6, Ruby 1.9.3 and PostgreSQL 9.1.3 is doing the searching...

In my controller (and using Kaminari) I have: 

```
def index
  @meals = Meal.text_search(params[:query]).sort_by(&:date).reverse.group_by(&:date).page(params[:page])
respond_to do |format|
  format.html # index.html.erb
  format.json { render json: @meals }
  end
end

```

And in my model I have the following search:

```
def self.text_search(query)
  if query.present?
    where("description @@ :q or meal_time @@ :q", q: query)
  else
    scoped
  end
end 

```

And in my view template:

```
<div class="container">
  <div class="row">
<%= form_tag meals_path, method: :get, :class => "well form-search" do %>
  <%= text_field_tag :query, params[:query], 
                     :class => "span3" %>
  <%= submit_tag "Search", name: nil, :class => "btn" %>
    <% if current_user %>
      <p class="pull-right"> 
    <%= link_to "Add a meal",
                new_meal_path,
                :class => 'btn btn-success' %>
    </p>
    <% else %>
    <% end %>
<% end %>       
</div>
<table class="table table-striped">
<tbody>
  <% @meals.each do |date, meals| %>
  <tr> 
    <td>
      <h2><%= date.to_s(:day_of_month) %></h2>
      <h6><%= date.to_s(:date_and_month) %></h6>
      <p><span class="badge badge-warning"><%= pluralize(meals.size, "meal") %></span></p>
    </td>
    <% meals.each do |meal| %>
      <td>
        <p>
          <strong>
            <%= meal.consumed_at.to_s(:just_the_time)%> 
            <%= meal.meal_time %> &#8212; 
            <%= meal.description %>
          </strong>
        </p>
        <%= link_to "Ingredients", meal_path(meal) %>
      </td>
      <% end %>
    </tr>
  <% end %>
</tbody>
</table> 
</div>
<%= paginate @meals %>  

```

This returns the following error:

```
NoMethodError in MealsController#index

undefined method `page' for Hash

```

Any help would be gratefully received!
