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

Solution
Building on roninek's response, I've found the best solution to be the following:
in /app/helpers/application.rb:
def with_format(format, &block)
old_format = @template_format
@template_format = format
result = block.call
@template_format = old_format
return result
end
In /app/views/foo/bar.json:
<% with_format('html') do %>
<%= h render(:partial => '/foo/baz') %>
<% end %>
An alternate solution would be to redefine `render` to accept a `:format` parameter.
I couldn't get `render :file` to work with locals and without some path wonkiness.
Problem
I'm trying to generate a JSON response that includes some HTML. Thus, I have `/app/views/foo/bar.json.erb`: ``` { someKey: 'some value', someHTML: "<%= h render(:partial => '/foo/baz') -%>" } ``` I want it to render `/app/views/foo/_baz.html.erb`, but it will only render `/app/views/foo/_baz.json.erb`. Passing `:format => 'html'` doesn't help.
