索引列出了所有内容，cancancan未过滤

Question

我有一个列出所有弹出窗口的视图，仅取决于用户，它不应该显示所有内容，因此我使用了cancancan进行过滤，但是它不再起作用。

我的观点（pops / index.html.erb）：

<% if @pops.present? %>
    <table class="table table-striped">
      <thead>
        <tr>
            <th scope="col">Titulo</th>
            <th colspan="4"></th>
        </tr>
      </thead>
      <% @pops.each do |pop| %>
      <tbody>
        <tr>                      
          <% if can? :index, Pop %> 
              <td scope="row"><%= pop.title  %></td>   
          <% end %>    
          <% if can? :show, Pop %>        
            <td><%= link_to 'Mostrar', pop %></td> 
          <% end %> 
          <% if can? :edit, Pop %>    
            <td><%= link_to 'Editar', edit_pop_path(pop) %></td> 
          <% end %> 
          <% if can? :delete, Pop %>    
            <td><%= link_to 'Excluir', pop, method: :delete %></td>     
          <% end %> 
          <% if can? :index_pdf, Pop %>
            <td><%= link_to 'Exportar', index_pdf_path(pop) %></td>
          <% end %>         
        </tr>
      </tbody>
      <% end %>
    </table>
<% end %>

我的模特

class Pop < ApplicationRecord
  enum charge: {
            Auxiliar: 1,
            Analista: 2,
            Coordenador: 3,
            Supervisor: 4,
            Gerente: 5,
            Diretor: 6
        }
    enum status: {
        active: 0,
        inactive: 1
    }
    has_many :pop_groups
    has_many :groups, :through => :pop_groups, :dependent => :destroy        
end

    include CanCan::Ability

    def initialize(user)
        if user
            if user.kind == 'user'

            end
        end
    end
end

我尝试了很多方法，但无法让他接受用户看不见的内容。 有人有什么想法吗？

好吧，我设法使它起作用。 这是代码。

<% @pops.each do |pop| %>
          <tbody>
            <% if can? :show, pop %>
                <tr>                      
                  <td><%= pop.title if can? :show, pop %></td>                
                    <td><%= link_to 'Visualizar', pop if can? :show, pop %></td>                  
                    <td><%= link_to 'Editar', edit_pop_path(pop) if can? :edit, pop %></td> 
                    <td><%= link_to 'Excluir', pop, method: :delete if can? :delete, pop %></td> 
                    <td><%= link_to 'Exportar', index_pdf_path(pop) if can? :index_pdf, pop %></td>     
                </tr>
            <% end %>
<%end%>

第一个“如果”是“每个”都不创建空行。 其他是查看用户是否具有权限的测试。
