Django: creating M2M relationship inline - django

Question

I'm trying to create a view with a formset of forms for the "Link" model. The problem is that in each form I would like the user to have the possibility of not just choosing from the already created TargetLink objects, but to edit them inline.
class ClientUrl(models.Model):
client = models.ForeignKey(UpstreamClientModel, null=True)
url = models.URLField(unique=True, null=False)
active = models.BooleanField(default=True)
def __unicode__(self):
return self.url
class Meta:
verbose_name = 'url'
ordering = ['url']
KEYWORD_TYPES = (
('PN', 'Pending'),
('MN', 'Money'),
('BR', 'Brand'),
('LT', 'Long Tail'),
)
class ClientKeyword(models.Model):
client = models.ForeignKey(UpstreamClientModel, null=True)
kw_type = models.CharField('keyword type', max_length=2,
choices=KEYWORD_TYPES, default='LT')
keyword = models.CharField(max_length=150, unique=False)
directions = models.CharField(max_length=200, blank=True,
help_text='e.g: 25 chars, use "affordable rental cars"')
def __unicode__(self):
return self.keyword
class Meta:
ordering = ['keyword', ]
unique_together = ('client', 'keyword')
class TargetLink(models.Model):
keyword = models.ForeignKey(ClientKeyword, related_name='target_links')
url = models.ForeignKey(ClientUrl, related_name='target_links')
def __unicode__(self):
return '{0}:{1}'.format(self.keyword, self.url)
class Link(models.Model):
client = models.ForeignKey(UpstreamClientModel, related_name='links')
target = models.ForeignKey(Target, related_name='links')
user = models.ForeignKey(User, blank=True, null=True, related_name='links')
link_type = models.ForeignKey(LinkType, related_name='links')
site = models.ForeignKey(Site, blank=True, null=True,
related_name='links')
site_url = models.URLField(blank=True,
help_text='leave blank until url is live')
month = models.DateField(blank=True, null=True)
target_links = models.ManyToManyField(TargetLink, related_name='links')
How could I accomplish this?

One way might be to have a form that is outside of your formset for the TargetLinks and use Knockout.js or another client-side framework to push the updated choices for TargetLinks to the target_links field in the formsets.
