运行分页代码时出现此错误:
undefined method `total_pages' for nil:NilClass
我听不懂,也许你可以帮我吗?
products_controller.rb
@products = Product.order(:nome).page params[:page]
帕吉纳:
<ul class="product-evaluation-rating">
<% avaliacao.questionario_respostas.approved.rated_questions.each do |answer| %>
<li class="product-evaluation-rating-item">
<%= answer.questionario_pergunta.custom_question %>
<%= content_tag :p, class: (answer.questionario_pergunta.custom_question == 'recomendaria' ? 'strong' : nil) do %>
<%= answer.custom_answer %>
<% end %>
</li>
<% end%>
</ul>
<%= paginate @products %>
kaminari_config.rb:
# frozen_string_literal: true
Kaminari.configure do |config|
# config.default_per_page = 25
# config.max_per_page = nil
# config.window = 4
# config.outer_window = 0
# config.left = 0
# config.right = 0
# config.page_method_name = :page
# config.param_name = :page
# config.params_on_first_page = false
end
答案 0 :(得分:0)
当我使用will_paginate gem时,我猜您正在使用
@products = Product.order(:nome).paginate(:page => params[:page])
此外,我看到您的视图会迭代
avaliacao.questionario_respostas.approved.rated_questions
,但您正在分页@products
。当您显示每行是产品的表且希望对其进行分页时,gem起作用,因此您不会在同一视图中全部显示它们。
我希望这会有所帮助。
