Each user has many *albums*, and each album has its many photos. And each
user has one *background image* to hold its many images. Similarly, a user
has one *profile picture* to hold its many images.
These are my models:
class UserProfile(models.Model):
user = models.OneToOneField(User)
permanent_address = models.TextField()
temporary_address = models.TextField()
profile_pic = models.ForeignKey(ProfilePicture)
background_pic = models.ForeignKey(BackgroundImage)
class Album(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=200)
pub_date = models.DateTimeField(default=datetime.now)
class Photo(models.Model):
album = models.ForeignKey(Album, default=3)
image = models.ImageField(upload_to=get_upload_file_name)
caption = models.CharField(max_length=200)
pub_date = models.DateTimeField(default=datetime.now)
class BackgroundImage(models.Model):
user = models.ForeignKey(User)
image = models.ImageField(upload_to=get_upload_file_name)
caption = models.CharField(max_length=200)
pub_date = models.DateTimeField(default=datetime.now)
class ProfilePicture(models.Model):
user = models.ForeignKey(User)
image = models.ImageField(upload_to=get_upload_file_name)
caption = models.CharField(max_length=200)
pub_date = models.DateTimeField(default=datetime.now)
I tried doing this, to let the user copy one image from
*ProfilePicture*to *Background
Image*, but didn't work:
# Get the user
>>>m = User.objects.get(username='m')
# Get its set of Profile pictures
>>>m_pro_set = m.profilepicture_set.all()
>>>m_pro_set
[<ProfilePicture: pro_mik>]
# Get its set of Background images
>>>m_back_set = m.backgroundimage_set.all()
>>>m_back_set
[<BackgroundImage: bg_mik>]
# Get an image object from Profile picture of the user
>>>m_pro_1 = m.profilepicture_set.get(id=2)
>>>m_pro_1
<ProfilePicture: pro_mik>
# Get an image object from Background image of the user
>>>m_back_1 = m.backgroundimage_set.get(id=2)
>>>m_back_1
<BackgroundImage: bg_mik>
# So, I tried to copy one image from *BackgroundImage* of a user *to*
*ProfilePicture*
>>>m_pro_set.objects.create(m_back_1)
* File "<console>", line 1, object has attribute 'objects'*
*AttributeError: 'QuerySet' object has no attribute 'objects'*
So my question is, how to copy an objects from one model to another? Any
advice will be much appreciated. Thank you!
