undefined method `total_pages' for #<Tuto::ActiveRecord_Relation:0x007fc3b2473d80>

Question

I found couple of similar cases but nothing to fix my problem...

I am using the gem Kaminari to paginate my app.

Since I added it, researches are failing and retrun this error undefined method total_pages' for #<Tuto::ActiveRecord_Relation:0x007fc3b2473d80>

I have a private method in my tutos controller to filter my tutos

 def filter_tutos
  return if params[:query].blank?
  @tutos = Tuto.search(params[:query][:keyword]).includes(:user, :category) if params[:query][:keyword].present?
  @tutos = Tuto.joins(:user).where('users.nickname LIKE ?', params[:query][:user]) if params[:query][:user].present?
  @tutos = Tuto.joins(:category).where('categories.name LIKE ?', params[:query][:category]) if params[:query][:category].present?
 end

index method in tutos controller :

  def index
    filter_tutos if params[:query].present?
    @tutos ||= Tuto.all.page params[:page]
  end

in my view I have:

  .pagination
      = paginate @tutos

I added paginates_per 5 in tuto model

Answer 1

Try this. Pagination is not called on @tutos . If it is blank then all Tuto objects are paginated but not otherwise.

  def index
    filter_tutos if params[:query].present?
    @tutos = @tutos.count > 0 ? @tutos : Tuto.all
    @tutos = @tutos.page params[:page]
  end
