Neo4j.rb - undefined local variable or method `model' for #

Question

Here is my controller:

  def index
    if params[:limit]
      @bisacs = Bisac.order(:bisac_code).page(params[:page]).per(params[:limit])
    else
      @bisacs = Bisac.order(:bisac_code).page(params[:page])
    end
  end

Here is my view:

<%= paginate @bisacs %>
<%= page_entries_info @bisacs %>

The error is:

undefined local variable or method `model' for #<Kaminari::Neo4j::Paginated:0x007ff2f211bf38>

For the line:

<%= page_entries_info @bisacs %>

What I am missing here?

But page_entries_info works when I am using this in the controller for other methods:

q = "
MATCH (b:Bisac)
WITH b, size((b)<-[:INCLUDED_IN]-()) as wokas_count
RETURN b.bisac_code as bisac_code, b.bisac_value as bisac_value, wokas_count, b.uuid as uuid
ORDER BY b.bisac_code
;"
@result = Neo4j::Session.current.query(q).to_a
if params[:limit]
  @result = Kaminari.paginate_array(@result).page(params[:page]).per(params[:limit])
else
  @result = Kaminari.paginate_array(@result).page(params[:page])
end

Here is more info about the error from the log file:

Answer 1

Changed the index method to use paginate_array.

  def index
    if params[:limit]
      @bisacs = Kaminari.paginate_array(Bisac.order(:bisac_code).to_a).page(params[:page]).per(params[:limit])
    else
      @bisacs = Kaminari.paginate_array(Bisac.order(:bisac_code).to_a).page(params[:page])
    end
  end

And got the

<%= page_entries_info @bisacs %>

working.
