I'm running through some djagno API examples and I'm having a problem
with how to order by a field in a different table. Here is what my
models:
class Blog(models.Model):
name = models.CharField(maxlength=100)
tagline = models.TextField()
def __unicode__(self):
return self.name
class Admin:
pass
class Author(models.Model):
name = models.CharField(maxlength=50)
email = models.EmailField()
def __unicode__(self):
return self.name
class Admin:
pass
class Entry(models.Model):
blog = models.ForeignKey(Blog)
headline = models.CharField(maxlength=255)
body_text = models.TextField()
pub_date = models.DateTimeField()
authors = models.ManyToManyField(Author)
def __unicode__(self):
return self.headline
class Admin:
pass
/////////
The documentation says that this will work:
Entry.objects.order_by('blogs_blog.name', 'headline')
However, when I run the above command I get the following error:
OperationalError: no such column: blogs_blog.name
////////////////
I don't understand blogs_blog.name? Thanks for your help
