我目前在我的_header中有3个循环
if current_user.admin? && !current_user?(user)
另外
<% if logged_in? %>
并且
<% else %>
如果我拿出
,一切正常,没有错误<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
</end>
当我将其粘贴回来时,我得到了错误。我不知道这种语法有什么问题。
有人可以帮忙吗?

您未正确关闭粘贴的if
:
<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
</end>
您应该尝试通过以下方式替换它:
<% if current_user.admin? && !current_user?(user) %>
<li><%= link_to "Admin", users_path %></li>
<% end %>

if循环中的if循环结构在if循环的ruby.your结束标记中是错误的。请参阅下面的
<%if%>
//condition here
<%end%>
答案 2 :(得分:-1)
<% if logged_in? && !current_user?(user) && current_user.admin? %>
<li><%= link_to "Admin", users_path %></li>
</end>

关闭if block syntex时出现Syntex错误。
1 <% if current_user.admin? && !current_user?(user) %>
2 <li><%= link_to "Admin", users_path %></li>
3 </end>
第3行出错,替换第3行,即</end> with <% end %>
