Ruby On Rails Rendering Partial

Question

Hi I am having problems with rendering a partial in a rails view.

I created a partial called _my_header.html.erb in the views/layouts directory.

Then in another file in a different folder in the views called index.html.erb I added:

 <% render 'layouts/my_header' %>

I put this inside a html tag. Anyway I am getting this error:

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>

Can you share the contents of your partial? I'm wondering if the error is in there, the error message notwithstanding. — Peter Alfvin, Jun 27 '13 at 11:15

You're using the wrong ERB-tags around it, <% %> is for executing code, but <%= %> is for printing code. So this is the correct code:

<%= render 'layouts/my_header' %>

The difference is explained here: What is the difference between <%, <%=, <%# and -%> in ERB in Rails?

And the official docs: http://api.rubyonrails.org/classes/ActionView/Base.html

<%= render 'layouts/my_header' %> You need to use <%= %> instead of <% %>, when you want ruby code to show smth in your template.

Just try the following code

<%= render '/layouts/my_header' %>

The above error specifies that there is no partials in the name of mobile_header. Are you sure you have a partial _mobile_header.mobile.erb in your layouts?
