callables cannot be serialized

[Joel Hooks-2]

Mainly to Nick:

I finally got to checking out 2550 as per your suggestion and it looks  
like it is still getting hung up on ImageField:

class StudioWatermark(models.Model):
     studio              = models.ForeignKey(Studio,  
related_name="watermark", unique=True)
     image               =  
models.ImageField(upload_to=get_studio_watermark,blank=True,null=True)
     text                = models.CharField(max_length=64)
     def __unicode__(self):
         return '%s Watermark' % (self.studio.name)

when I try and encode this it spits back:

Traceback (most recent call last):
   File "<console>", line 1, in <module>
   File "/usr/lib/python2.6/dist-packages/pyamf/__init__.py", line  
1103, in encode
     encoder.writeElement(el)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 503, in  
writeElement
     func(data)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 733, in  
writeObject
     self.writeElement(obj_attrs[key])
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 503, in  
writeElement
     func(data)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 739, in  
writeObject
     self.writeElement(value)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 503, in  
writeElement
     func(data)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 739, in  
writeObject
     self.writeElement(value)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 503, in  
writeElement
     func(data)
   File "/usr/lib/python2.6/dist-packages/pyamf/amf0.py", line 461, in  
writeFunc
     raise pyamf.EncodeError("Callables cannot be serialised")
EncodeError: Callables cannot be serialised

I'm assuming this is because I am using a function in the upload_to  
property, but I thought this was addressed? The same issue occurs in  
trunk.

Hi Joel,

could you open a new ticket for this?

Looks like the unit test is also failing, I'll open a separate ticket  
for that:
http://buildbot.pyamf.org/builders/ubuntu-py25/builds/292/steps/python2.5-test_4/logs/stdio/text

Cheers,

Thijs
