Ruby On Rails渲染部分
[英]Ruby On Rails Rendering Partial
问题描述
Hi I am having problems with rendering a partial in a rails view. 
嗨我在rails视图中渲染部分时遇到问题。
I created a partial called _my_header.html.erb in the views/layouts directory. 我在views / layouts目录中创建了一个名为_my_header.html.erb的部分。
Then in another file in a different folder in the views called index.html.erb I added: 然后在名为index.html.erb的视图中的另一个文件夹中的另一个文件中添加了：
<% render 'layouts/my_header' %>
I put this inside a html tag. 我把它放在一个html标签里面。 Anyway I am getting this error: 无论如何，我收到此错误：
ActionView::MissingTemplate in User#index
Showing C:/Buzzoo/Buzzoo/app/views/user/index.erb where line #2 raised:
Extracted source (around line #2):
1: <html>
2: <% render 'layouts/my_header' %>
3:
4: <body>

You're using the wrong ERB-tags around it, <% %> is for executing code, but <%= %> is for printing code. 你在它周围使用了错误的ERB标签， <% %>用于执行代码，但<%= %>用于打印代码。 So this is the correct code: 所以这是正确的代码：
<%= render 'layouts/my_header' %>
The difference is explained here: What is the difference between <%, <%=, <%# and -%> in ERB in Rails? 这里解释了不同之处 ： Rails中ERB中的<％，<％=，<％＃和 - ％>有什么区别？
And the official docs: http://api.rubyonrails.org/classes/ActionView/Base.html 官方文档： http ： //api.rubyonrails.org/classes/ActionView/Base.html

<%= render 'layouts/my_header' %>当您希望ruby代码在模板中显示smth时，需要使用<%= %>而不是<% %> 。

只需尝试以下代码即可
<%= render '/layouts/my_header' %>

ActionView::MissingTemplate in Player#index Showing C:/Buzzoo/Buzzoo/app/views/player/index.mobile.erb where line #2 raised: Missing partial /layouts/mobile_header with {:locale=>[:en], :formats=>[:mobile], :handlers=>[:erb, :builder, :coffee]}.
@user2527785 @ user2527785
The above error specifies that there is no partials in the name of mobile_header. 上述错误指定mobile_header名称中没有部分内容。 Are you sure you have a partial _mobile_header.mobile.erb in your layouts? 您确定布局中有部分_mobile_header.mobile.erb吗？
