我的rails服务器说它已经在我的页面中呈现了我的部分,但内容不存在。 即使我使用Chrome DevTools检查页面上的元素,也不会出现应该渲染的div。
编辑:修复了这个问题,但现在部分内部的部分内容无法呈现。我会为这个问题提出新的问题。
show.html.erb
(有修复):
<% provide(:title, @user.name) %>
<% provide(:pagetitle, @user.name) %>
<% render'layouts/relation' unless current_user?(@user)%>
<div id="stats">
Player Statistics will appear here.
</div>
<div id="characters">
Player Characters will appear here.
</div>
_relation.html.erb
(部分):
<div id="relation">
<% if current_user.friends?(@user) %>
<%= render 'layouts/edit_relation', locals: { action: "rm-friend" } %>
<% elsif current_user.req_friends?(@user) %>
Friend Request Pending...
<% elsif current_user.pend_friends?(@user) %>
<%= render 'layouts/edit_relation', locals: { action: "add-friend" } %>
<%= render 'layouts/edit_relation', locals: { action: "rej-friend" } %>
<% else %>
<%= render 'layouts/edit_relation', locals: { action: "req-friend" } %>
<% end %>
</div>
_edit_relation.html.erb
(部分内部的部分):
<% case :action %>
<% when "req-friend"%>
<%= form_for(current_user.relation.build(character: @user.id, type: "freq"), remote: true) do |f| %>
<div><%= f.hidden_field :character %></div>
<div><%= f.hidden_field :type %></div>
<%= f.submit "Add Friend", class: "btn btn-large btn-primary" %>
<% end %>
<% when "add-friend"%>
<%= form_for(current_user.relation.build(character: @user.id, type: "friend"), remote: true) do |f| %>
<div><%= f.hidden_field :character %></div>
<div><%= f.hidden_field :type %></div>
<%= f.submit "Accept Request", class: "submit" %>
<% end %>
<% when "rej-friend" %>
<%= form_for(current_user.reverse_relation.find_by(owner: @user.id, type: "freq"), html: { method: :delete }, remote: true) do |f| %>
<%= f.submit "Reject Request", class: "submit" %>
<% end %>
<% when "rm-friend"%>
<%= form_for(current_user.reverse_relation.find_by(owner: @user.id, type: "friend"), html: { method: :delete }, remote: true) do |f| %>
<%= f.submit "Remove Friend", class: "submit" %>
<% end %>
<% end %>
我的服务器日志表明部分已经呈现:

有什么想法吗?
答案 0 :(得分:2)
您需要使用渲染ERB标记:
<%= render 'layouts/relation' unless current_user?(@user) %>
答案 1 :(得分:1)
你错过了=
-
<%= render 'layouts/relation' unless current_user?(@user) %>
调用render
仍会生成字符串,这就是您在日志中看到它的原因;如果没有等号,它就不会出现在页面上。

所以从你的布局/关系部分你渲染另一个部分(layouts / edit_relation),对吗?也许这就是问题所在。
