Hi - how do you trigger an xml response for "respond\_to do |format|’ ?

Wondering why the following isn’t working for me (i.e. triggers HTML  
response)

------------------view ----------------  
\<% _remote\_form\_for_ :bi\_allocation, @bi\_allocation, :url =\> {  
:controller  
=\> “bi\_allocation”, _:action =\> “r\_create”_} do |f| %\>  
\<%= f.text\_field :amount, :size =\> 10 %\>  
\<%= submit\_tag ‘Create’ %\>  
\<% end %\>

------------ controller ---------------------  
_def r\_create_  
@bi\_allocation = BiAllocation.new(params[:bi\_allocation])  
respond\_to do |format|  
if @bi\_allocation.save  
format.html raise("\*\*\* _HITS THIS LINE_ \*\*\*")  
format.xml { render :xml =\> @bi\_allocation, :status =\>  
:created,  
:location =\> @bi\_allocation} _# Doesn’t hit this line_  
else  
format.html { render :action =\> “xxxx” }  
format.xml { render :xml =\> @bi\_allocation.errors }  
end  
end  
end

thanks

try calling it with :format =\> ‘xml’

\<%= link\_to “link\_name”, :controller =\> ‘controller\_name’, :action =\>  
‘action\_name’, :format =\> ‘xml’ %\>

tks - the remote\_form\_for method doesn’t mention a “:format” parameter?  
actually the “link\_to” method (which you used in your example) I see  
doesn’t mention this either? Just wondering how one would have found  
out  
about this being an option here?
