Creating an XML string in Flex (AS3) by using DOM functions

Question

I'm new to rails programming and i'm trying to use rails status code when raising a grape exception but my tests are failing. I couldn't find any example on grape documentation so this may be impossible.

I want to know if it is possible and if not, why so?

This works:

rescue_from Example::IsExampleWorking do |_e|
    error!({ messages: ["Example is not working because it was not found"] }, 404)
end

But this does not:

rescue_from Example::IsExampleWorking do |_e|
    error!({ messages: ["Example is not working because it was not found"] }, :not_found)
end

My test is:

it "return a 404 Not Found status" do
  expect(response).to have_http_status(:not_found)
end

edit: guys, I forgot to mention that the error message from he test is

undefined method `to_i' for :not_acceptable:Symbol
Did you mean?  to_s

But I didn't find any documentation on grape's docs to make sure they accept only integer as second param.

Thank you :)

Solution 1

Stay away from XMLNode if you're using as3, it's a legacy class, the new XML and XMLList classes are the ones that support the excellent E4X. Using those it's as easy as this:

var myXML:XML = <slide />;
myXML.@thumb="http://www.thumbs.com/thumb.jpg";
myXML.@type="static";
myXML.@blah="bleh";
trace("myXML", myXML.toXMLString());

The @ means it's an attribute, not using that would add child nodes instead.

Solution 2

This would probably be easier:

var thumb:String = "http://www.thumbs.com/thumb.jpg";

var type:String = "static";

var blah:String = "bleh";

var xml:XML =        

          <Relyon>
             <slide thumb={thumb} type={type} blah={blah} />
          </Relyon>;


trace( xml.toXMLString() );

//traces out

 <Relyon>
     <slide thumb="http://www.thumbs.com/thumb.jpg" type="static" blah="bleh"/>
 </Relyon>

Hi, welcome to SO. Can you please also post the code you are testing.

Yeah. You might create an issue in grape repo with this question. One of the solutions would be to use Rack::Utils::SYMBOL_TO_STATUS_CODE[:not_found]. I would prefer just a number in that case :)
