问题
I am getting ActionView::MissingTemplate error when using render_to_string method with partial views, below the code
bizz = render_to_string(:partial => "biz_new",:layout => false)
Even though i have explicitly specified :layout => false, i am getting the MissingTemplate error always.
But render_to_string with normal views works fine in the same project. what could be the reason?
below the stack trace
ActionView::MissingTemplate (Missing partial businesses/biz_new with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:text, "/"], :locale=>[:en, :en]} in view paths "/home/ramesh/works/xxx/app/views", "/home/ramesh/works/xxx/vendor/plugins/asset_packager/app/views"):

Try
render_to_string("_biz_new", :formats => [:html], :layout => false, :locals => {:biz => @biz})
render_to_string needs the starting underscore and the .html extension.

As Mike Kijewski mentioned, you can include the underscore at the beginning of the partial name, but if you use the .html in the end you will get a deprecation warning. A more straightforward way is this:
render_to_string(:partial => "folder_name/_partial_name", :formats => [:html], :layout => false, :locals => {:a_needed_argument_for_the_partial => @arg})

It looks like rails is expecting the file to be in format txt. What's the file named ? Try naming it:
_biz_new.txt.erb
-or-
businesses/_biz_new.txt.erb

Had similar issue.
I found a solution:
render_to_string(model, :formats => [:html])
