Building on <a href="https://stackoverflow.com/questions/339130/how-do-i-render-a-partial-of-a-different-format-in-rails#340335">roninek's response</a>, I've found the best solution to be the following:

in /app/helpers/application.rb:

<pre><code>def with_format(format, &amp;block)
 old_format = @template_format
 @template_format = format
 result = block.call
 @template_format = old_format
 return result
end
</code></pre>

In /app/views/foo/bar.json:

<pre><code>&lt;% with_format('html') do %&gt;
 &lt;%= h render(:partial =&gt; '/foo/baz') %&gt;
&lt;% end %&gt;
</code></pre>

An alternate solution would be to redefine <code>render</code> to accept a <code>:format</code> parameter.

I couldn't get <code>render :file</code> to work with locals and without some path wonkiness.

What's wrong with

<pre><code>render :partial =&gt; '/foo/baz.html.erb'
</code></pre>

? I just tried this to render an HTML ERB partial from inside an Atom builder template and it worked fine. No messing around with global variables required (yeah, I know they have "@" in front of them, but that's what they are).

Your <a href="https://stackoverflow.com/questions/339130/how-do-i-render-a-partial-of-a-different-format-in-rails#340432"><code>with_format &amp;block</code> approach</a> is cool though, and has the advantage that you only specify the format, whereas the simple approach specifies the template engine (ERB/builder/etc) as well.

Following is a nice way to do it

blocks|key|1675950|text|对于Rails3，with_format块可以工作，但它有一点不同：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1675951|++def+with_format(format,+&block)
++++old_formats+=+formats
++++self.formats+=+[format]
++++block.call

For Rails 3, the with_format block works, but it's a little different:

<pre><code> def with_format(format, &amp;block)
 old_formats = formats
 self.formats = [format]
 block.call
 self.formats = old_formats
 nil
 end
</code></pre>

blocks|key|1460935|text|在Rails3中，视图有一个格式数组，这意味着您可以将其设置为查找:mobile，:html。默认设置为查找:移动模板，但后退到:html模板。设置它的效果将级联到内部偏音中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1460936|我能找到的最好的，但仍然有缺陷的方法是将这一行放在每个完整的移动模板(但不是部分)的顶部。|1460937|<%25+self.formats+=+[:mobile,+:html]+%25>|code-block|syntax|javascript|1460938|缺陷是您必须将该行添加到多个模板中。如果有人知道在application_controller.rb中设置这一点的方法，我很想知道。不幸的是，将这一行添加到您的移动布局中是行不通的，因为模板是在布局之前呈现的。|1460939|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In Rails 3, the View has a formats array, which means you can set it to look for [:mobile, :html]. Setting that will default to looking for :mobile templates, but fall back to :html templates. The effects of setting this will cascade down into inner partials.

The best, but still flawed way, that I could find to set this was to put this line at the top of each full mobile template (but not partials). 

<pre><code>&lt;% self.formats = [:mobile, :html] %&gt;
</code></pre>

The flaw is that you have to add that line to multiple templates. If anyone knows a way to set this once, from application_controller.rb, I'd love to know it. Unfortunately, it doesn't work to add that line to your mobile layout, because the templates are rendered before the layout.

blocks|key|1461029|text|从Rails+3.2.3开始，当调用render+:partial时(只在respond_to块外部工作)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1461030|render+formats:+[+:html+]|code-block|syntax|javascript|1461031|而不是|1461032|render+format:+'html'|1461033|entityMap^0|11|A|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|P|$]]

Beginning with Rails 3.2.3, when calling render :partial (only works outside of the <code>respond_to</code> block).

blocks|key|1676217|text|似乎传递一个formats选项可以在更新的Rails版本中正确地呈现它，至少是3.2版本：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1676218|{

Rails 4 will allow you to pass a formats parameter. So you can do 

<pre><code>render(:partial =&gt; 'form', :formats =&gt; [:html])} 
</code></pre>

Note you can do something similar in Rails 3 but it wouldn't pass that format to any sub partials (if form calls other partials).

You can have the Rails 4 ability in Rails 3 by creating config/initializers/renderer.rb:

<pre><code>class ActionView::PartialRenderer
 private
 def setup_with_formats(context, options, block)
 formats = Array(options[:formats])
 @lookup_context.formats = formats | @lookup_context.formats
 setup_without_formats(context, options, block)
 end

 alias_method_chain :setup, :formats
end
</code></pre>

I had a file named 'api/item.rabl' and I wanted to render it from an HTML view so I had to use:

<code>render file: 'api/item', formats: [:json]</code>

(<code>file</code> because the file have no underscore in the name, <code>formats</code> and not <code>format</code> (and passes and array))

I'm trying to generate a JSON response that includes some HTML. Thus, I have <code>/app/views/foo/bar.json.erb</code>:

<pre><code>{
 someKey: 'some value',
 someHTML: "&lt;%= h render(:partial =&gt; '/foo/baz') -%&gt;"
}
</code></pre>

I want it to render <code>/app/views/foo/_baz.html.erb</code>, but it will only render <code>/app/views/foo/_baz.json.erb</code>. Passing <code>:format =&gt; 'html'</code> doesn't help.

How do I render a partial of a different format in Rails?
