TypeError:无法将Symbol转换为Integer

我收到“活动中的TypeError#member - 无法将符号转换为整数”

我会说我的95%的记录工作正常,但我有一对不断绊倒这个错误。我从哪里开始研究这个问题。

以下是我正在使用的代码:

.html.erb page

<div id="listing-gallery">
<ul id="listing-slides">
    <% listing.slides.each_with_index do |slide, i| %>
        <%= content_tag :li, :id => "slide#{i}", :class => (i == 0) ? "active" : "" do %>
            <%= image_tag slide[:large] %>
        <% end %>
    <% end %>
</ul>
<ul id="listing-slide-thumbs">
    <% if listing.slides.count > 1 %>
        <% listing.slides.each_with_index do |slide, i| %>
            <%= content_tag :li, :class => (((i+1)%4 == 0) ? "last" : "") do %>
            <%= content_tag :a, :href => "#slide#{i}" do %>
                    <span class="hover"></span>
                    <%= image_tag slide[:thumb] %>
            <% end %>
            <% end %>
        <% end %>
    <% end %>
</ul>

.activities_controller.rb

def member
# Assign attrs if venue exists
if @member.nil? || @member.venue.nil?
  redirect_to activities_path
else
  if @member.venue.attrs.count > 0
    # match_by_type can be found in the ApplicationHelper
    @attrs = match_by_type @member.venue.attrs
  else
    @attrs = nil
  end

  unless @member.venue.nil?
    unless @member.venue.attrs.nil?
      @member_rentals = @member.venue.attrs.all_by_type("Rentals")
    end
  end  
end
end

我从哪里开始?

1 个答案:

答案 0 :(得分:0)

请参阅<%= image_tag slide[:large] %><%= image_tag slide[:thumb] %>

image的{​​{1}}属性是什么?

如果slideimage的属性,我认为如下:

slide

或者如果使用carrierwave

<%= image_tag slide.image.url(:large) %>

顺便说一句,我在<%= image_tag slide.image_url(:large).to_s %>

上看不到listing.slides
