Hi I cant seem to figure out this problem. Im using Nokogiri to
connect to an API and parse the XML response. I am then trying to
display it in my view. I can se the data in my Terminal when I do some
debugging on the XML object but cant seem to get it to the view. I
have pasted some of the code here

Please all help is appreciated.
Thanks!!

So, what happens when you try and access view this page in your
browser ? have you verified what @news contains ?

Hi Fred!
I did some output on the @news object in my view and I do get some
console output of the xml response but in the browser its empty. How
do you do some descent debugging on objects in Rails 3?! First I did
some good old puts and then I merely did <%= @news %>. So to round it
up. It seems though as @news contains the xml but I cant display it in
the browser. Also I cant see the
When I debug in the browser the DOM stops at
Feeling a bit confused about this:)
Has anyone else any feedback to give me on this?! I still havent
progressed in the matter. Really frustrating. Thanks in advance!!

You can use ruby-debug to break into the code (model, controller or
view) in order to inspect data. See the Rails Guide on debugging for
how to do this, and other tips for debugging.

Have you tried doing:
raise @news.to_yaml
In the controller and seeing that that brings?
Hmm I did as you said John but Im just getting an undefined method
`to_yaml=’ for nil:NilClass. Is my object empty?! is that what
happens?? Thanks?!

So what did you learn from debugging it?

Well Colin Im a bit confused. I had some problems with installing the
ruby-debug as Im using Rails 3. So finally I gave up with that.
Persevere. Rails 3 should be no problem. Did you follow the guide
here:
If so what problem did you have? You need to be able to break into
code and inspect data and run code snippets to see what is wrong.
Even if you sort out your current issue there will be another that
needs the debugger.

Well Colin Im a bit confused. I had some problems with installing the
ruby-debug as Im using Rails 3. So finally I gave up with that. But
when I did puts doc.to_s I get the xml in my console so I have it
there. But the line after where I do this: @news = doc.css(‘news’).map
do |n|
I tried to do @news.to_s and that gave me nothing. Also I did raise
@news.to_yaml which just game me an error. Do u have any clues on
that?!
Regards!
I finally managed to debug more around the @stories variable. This is
an outtake from it (rdb:14) display @stories
1: @stories =
(rdb:14) show @stories
Unknown show command @stories
(rdb:14) p @stories
nil
(rdb:14) pp stories
NameError Exception: undefined local variable or method `stories’ for
#NewsController:0x102ece778
(rdb:14)
So my conclusion is from this segment of code: apiKey = (“http://
mysomething.com - This website is for sale! - my something Resources and Information.”)
doc = Nokogiri::XML(open(apiKey).read) ← here I have the xml
response and all is dandy
but the next line I do this:
@stories = doc.css(“.item”).map do |n| <–here its empty.
h = {}
%w(header source_name summary url geo created_at
type_of_media).each do |key|
h[key.to_sym] = n.css(key).text
end
News.new(h)
end
How is this possible? I might be new to ruby and rails but Im feeling
really lost. Any good feedback?!
Thanks!
Colin! I did this in debugger mode.
display @stories
1: @stories =
It seems as though he object is empty? As i suspected. I cant
understand how it can be when I am declaring it with the doc container
which should contain the api url?? Very confusing this. Im trying to
invoke the debugger around this peace of code but without success
debugger
@stories = doc.css(".item").map do |n|
Here I cant even get in to debug mode. Grateful for all your help.
Thanks!
Hi Fred!
The bit wich fetches the xml and parses it I have done a regular puts
on that many times and i did ‘var local’ in debugger mode which
displayed all local variables and then I got all the xml output.
Before I did the debugging actually before it has been set. Im trying
to do it after now as well but for some reason it has problems going
in to debug mode. I do Rails s --debugger and it says that “Debugger
enabled” but it doesnt get there. Do you have any feedback from the
link a pasted with code on refactormycode.com? Is it something
obviously wrong Im doing when declaring the variabe?
Thanks in advance!

Are you inspecting the variable before or after it has been set?
Have you tried refactoring the bit which fetches and parses the xml
feed into its own class so that you can more easily play with it in
the console (and test it) ?
