article_tree helper 方法

def article_tree(space, category = nil)
  if category.nil?
    articles = Article.roots.where(space: space)
  else
    articles = Article.roots.where(space: space, category: "article-#{category}")
  end

  if articles.blank?
    return
  end

  html = '<ul>'

  if !category.nil?
    html += '''
      <li class="branch">
        <a class="node-title category" href="javascript:;">
          <span>'+ Article::CATES[category] +'</span>
          <i class="icon fa"></i>
        </a>
        <ol>
    '''
  end

  articles.each do |article|
    html += render :partial => 'articles/tree', :locals => {:article => article}
  end

  if !category.nil?
    html += '</ol></li>'
  end

  html += '</ul>'
  raw html
end

articles/_tree.html.erb

<li class="<%= article.children.blank? ? 'leaf' : 'branch' -%>">
  <%= link_to article_path(space: article.space, category: article.category_short, slug: article.slug),
    class: "node-title #{ is_active?(article.slug) }" do %>
    <%= content_tag :span, article.locale_title %>
    <i class="icon fa fa-2"></i>
  <% end %>

  <% unless article.children.blank? %>

    <% article.children.each do |article| %>
      <%= render :partial => "articles/tree", :locals => {:article => article} %>
    <% end %>
  </ol>
  <% end %>
</li>

系统环境:

ruby 2.4.0p0
rails: 5.0.1
mongoid: 6.0.3

上面这个异常是偶发的,相同的请求 10 次可能出现 1 次,看最近的日志里面 1208 个请求里面出现了 140 次

好久不用 Rails 了,实在是没查出来问题原因 😭

https://github.com/DatabaseCleaner/database_cleaner/issues/466

降到 2.3.1 后解决了

(wrong argument type Integer (expected Proc)) 从字面上看,是不是参数不应该是 integer 型的,应该传进个 Proc 型的进去

#1 楼 @gakki 上面这个异常是偶发的,相同的请求 10 次可能出现 1 次

给下行号吧,都不知道 30,28 是哪一行。
