Question

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.

Answer 1

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.
