Candidates response fails on _dict_cleanup

[aolieman]

Hey,

Thanks for writing this nice wrapper. It makes Spotlight calls a lot more convenient!

I'm running into a problem with the candidates response, seemingly only when exactly two candidate URIs are found for a surface form.

>>> text = "Industrial Design at the Technische Universiteit Delft"
>>> compare.throughSpotlight(text, candidate_param)

Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    compare.throughSpotlight(text, candidate_param)
  File "...\git-code\compare.py", line 44, in throughSpotlight
    spotlight_response = api(text)
  File "build\bdist.win32\egg\spotlight\__init__.py", line 206, in candidates
    for form in pydict['annotation']['surfaceForm']]
  File "build\bdist.win32\egg\spotlight\__init__.py", line 60, in _dict_cleanup
    for key, value in dic.iteritems():
AttributeError: 'unicode' object has no attribute 'iteritems'

With curl:

$ curl -H "accept: application/json" http://spotlight.sztaki.hu:2222/rest/candidates --data "text=Industrial Design at the Technische Universiteit Delft&confidence=0&support=0"

{
   "annotation":{
      "@text":"Industrial Design at the Technische Universiteit Delft",
      "surfaceForm":{
         "@name":"Technische Universiteit Delft",
         "@offset":"25",
         "resource":[
            {
               "@label":"Technische Universiteit Delft",

            },
            {
               "@label":"Delft University of Technology",
               "@uri":"Delft_University_of_Technology",

            }
         ]
      }
   }
}

I'm not entirely sure what the conditions are under which _dict_cleanup() fails, but I have only found examples with exactly two candidate URIs. If needed, I can provide you with some more examples.

Any idea what is causing this hiccup?

Cheers,
Alex

May I ask which version if spotlight you are running?

[aolieman]

Of course you may :-)!

Locally I'm fairly certain the version is 0.6.5 and at http://spotlight.sztaki.hu:2222 it should also be 0.6.5. The responses from my local server and the sztaki.hu server are the same.

Doesn't the issue reproduce with your server?

[originell]

Haha no, or at least it was not above our notification threshold oops.

I have a fix which I'm pushing in the next 15 minutes. That happens because in candidates we are assuming that it's a list, which it does not have to be, as your case demonstrates :)

[aolieman]

That's great, I'll try it right away!
Especially great since your fix is faster than me trying to bypass _dict_cleanup() alltogether ;-)

[originell]

So that should be fixed now! Would not have been that fast if you would not have supplied the raw curl response :) Thanks for that. Hope it works? Waiting for your confirmation!

[aolieman]

It works like a charm =)! Many thanks for your fast (and late-night) bugfix; I wasn't expecting that!

[originell]

Glad to hear that! Well, I'm recovering a RAID5, so if you encounter any other error tonight, chances are high that I'll be awake and able to fix it ;-)

Have fun with spotlight!
