Hello, guys.
This is Django 1.4.
I have this code from my view:
my_art = ArtworkModel.objects.get(id=pk)
comments = CommentModel.objects.filter(artwork=pk)
artForm = ArtworkForm(instance=my_art)
...
These models:
class ArtworkModel(models.Model):
"""
This class contains the information necessary to describe a piece of
artwork uploaded to my website. Technically, the artist field is
unnecessary, but I'm throwing it in because I'd like to be able
to upload collaborations.
"""
MEDIUMS = (('ink', 'ink'),
('graphite', 'graphite'),
('watercolor', 'watercolor'),
('oil', 'oil'),
('acrylic', 'acrylic'),
('digital', 'digital'),
('sculpture', 'sculpture'),
('other','other'))
title = models.CharField(max_length=200)
medium = models.CharField(max_length=200, choices=MEDIUMS,
default='graphite')
upload_date = models.DateTimeField(auto_now_add=True)
artist = models.CharField(max_length=200)
image = models.ImageField(upload_to=getFilePath)
desc = models.TextField(verbose_name="Description", max_length=500)
class Meta:
ordering = ['title']
def __unicode__(self):
return '-'.join((self.title, self.artist, self.medium))
class CommentModel(models.Model):
"""
This class contains the information necessary to describe a comment
that someone's left about a piece of artwork.
"""
commenteer = models.CharField(max_length=200, blank=False)
comment_body = models.TextField(blank=False)
artwork = models.ForeignKey(ArtworkModel)
date = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['date']
And this traceback:
Traceback:
File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py"

111. response = callback(request, *callback_args,

model_to_dict
111. opts = instance._meta
Exception Type: AttributeError at /artwork/8/modify/
Exception Value: 'QuerySet' object has no attribute '_meta'
The internet says I should be using a regular Model instance rather than a
QuerySet to populate my form. The thing is that I think I AM using a
regular model. I'm not even using
those CommentModels yet. I don't understand why this is failing? Please
help?
