Question

I’m building a “preview” function into the CMS for my website which uses the existing front-end template to render a model. This model has an association:

class FeatureWork(models.Model):
    name = models.CharField(max_length=100)
    ...

class FeatureWorkLink(models.Model):
    feature_work = models.ForeignKey(FeatureWork)

In the view for the preview, I’m trying to build the model such that when the template calls feature.featureworklink_set.all it returns the associated links. Since neither model has been saved yet, all the standard Django form techniques seem to go out the window.

This is what I have so far, but it blows up when I call the add method on the manager, since the parent hasn’t been saved yet:

form = FeatureWorkAdminForm(initial=request.POST)
featured = form.save(commit=False)
for link in request.POST['links'].split(","):
    featured.featureworklink_set.add(FeatureWorkLink(image=link))

Why don’t you just add:

preview = BooleanField()

to your models, save everything to database and don’t look for hacks. This way you can have drafts for free.
