    <p>I have two models:</p> <pre><code>class Studio(models.Model): name = models.CharField("Studio", max_length=30, unique=True) class Film(models.Model): studio = models.ForeignKey(Studio, verbose_name="Studio") name = models.CharField("Film Name", max_length=30, unique=True) </code></pre> <p>I have a Film form that allows the user to either select a preexisting Studio, or type in a new one:</p> <pre><code>class FilmForm(forms.Form): studio = forms.ModelChoiceField(Studio.objects, required=False) new_studio = forms.CharField(max_length=30, required=False, label = "New Studio Name") name = forms.CharField(max_length=30, label = "Film Name") </code></pre> <p>There's validation to assure that the new_studio name doesn't already exist. If the user enters a new_studio, I want to save the studio and then save the new Film. </p> <pre><code>form = FilmForm(request.POST) if form.is_valid(): # All validation rules pass std = Studio(name = form.cleaned_data['new_studio']) std.save() </code></pre> <p>But then how do I save the Film instance subject to the brand new studio id? I've seen <a href="https://stackoverflow.com/questions/3953206/django-foreign-key-save">this question</a>, but what if I have many more fields in the Film model and Film Form? If I use the linked answer, I would have to enter each field:</p> <pre><code>studio = Studio.objects.get(name=request.POST['new_studio']) newFilm=Film(name=form.name, studio=studio, field_one = form.field_one, field_two = form.field_two, etc.) </code></pre> <p>What is the correct way to implement this?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
