有人可以告诉我哪里出错了吗
在我的视图文件中,我有以下代码
<div>
<ul>
<% CategoryOutsourceadvert.include(:advert).all do |categoryoutsourceadvert| %>
<li>
<%= check_box_tag('q[category_outsourceadverts_id_eq_any][]', categoryoutsourceadvert.id ) %>
<%= categoryoutsourceadvert.name %> (<%= categoryoutsourceadvert.adverts.uniq.count %>)
</li>
<% end %>
</ul>
</div>
模型
Advert belongs_to category_outsourceadvert
CategoryOutsourceadvert has_many adverts
在我的终端我收到错误我不明白:
TypeError - wrong argument type Symbol (expected Module):
app/views/adverts/_index.html.erb:134:in `block in _app_views_adverts__index_html_erb___100043438257983213_70223712632760'
有人可以向我解释这个错误意味着什么吗?
答案 0 :(得分:5)
你忘记了&#39;:
CategoryOutsourceadvert.includes(:advert).all
答案 1 :(得分:1)
您必须使用联接替换包含,因此它看起来像CategoryOutsourceadvert.joins(:advert).all
