Kaminari Not working due to group keyword

@users = User.registred
        .includes(:items)
        .joins('LEFT OUTER JOIN items ON users.id=items.user_id')
        .group(User.column_names.collect do |c| "#{User.table_name}.#{c}" end.join(','))
        .order('CASE WHEN LENGTH(users.profile_picture) > 0 THEN 0 ELSE 1 END, followers_count DESC, bibbed_items_count DESC, SUM(items.user_likes_count) DESC, users.id')

where registered = where("deactivated_at IS NULL AND last_sign_in_at IS NOT NULL")

Kaminari not working with group clause. How to optimized group clause in this query ?

Solution

  • I fixed it using this:

    @users = User.registred
        .includes(:items)
        .joins('LEFT OUTER JOIN items ON users.id=items.user_id')
        .group("users.id")
        .order('CASE WHEN LENGTH(users.profile_picture) > 0 THEN 0 ELSE 1 END, followers_count DESC, bibbed_items_count DESC, SUM(items.user_likes_count) DESC, users.id')

@users = @users.page(params[:page])
