I am stucked at some major issue with the AjaxForm and render\_to\_string.

I am using AjaxForm for uploading images with other details since the  
Ajax  
Upload library isn’t even using Ajax. So once the form is submitted i  
need  
to call a partial and return it in a json format. but the problem is  
that  
the render\_to\_string is not working at all. In case if i am returning  
simple  
string then it’s working fine.

reference [jQuery Form Plugin](http://jquery.malsup.com/form/#file-upload)

#Server Ruby on rails  
def some\_action  
respond\_to do |format|  
@html = render\_to\_string(:partial =\> “form.html.erb”, :object =\>  
[@obj1,  
@obj2])  
json = { :success =\> “Added successfully”, :html =\> @html }  
format.html { render :json =\> json }  
end  
end

#client side  
$(“#upload”).ajaxForm({  
dataType: “json”,  
success: function(response) {  
console.log(response);  
console.log(response.html);  
});  
return false;  
});

Thanks for any help
