I am developing an API for my application.
Here is the standard show method.
def show
@city = City.find(params[:id], :include => :state)
respond_to do |format|
format.html
format.xml
end
end
For a browser based action if the params[:id] is missing then
ActiveRecord::RecordNotFound exception is raised which I let Rails handle.
This results in public/404.html.
However in API I need to catch the exception and then I need to return an
xml with the error message. What is the best way to handle that. Any
example will be helpful
Right now even if I catch the exception then after catching the exception I
need to process two different ways for html and xml. Secondly I need to know
if I am processing html or xml. How do I find out if I am handing html or
xml. Is there a utility method?

Look at the bottom of the create or update methods in the controller. Both have examples of handling errors that should serve as examples.

The update scenario doesn''t handle if @city = City.find(params[:id]) throws ActiveRecrod::RecordNotFound exception. I want to return an xml stating that no record was found for the given id. I can catch the exception but am not sure what is the best way to handle this case when I must return an xml response every single time. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
