I'm trying to make a page that allows a user to edit/add many models at
once. Let me give an example:
class SolarSystem(models.Model):
name = models.CharField(...)
description = models.CharField(...)
class Planet(models.Model):
name = models.CharField(...)
solarsystem = models.ForeignKey(SolarSystem)
I want the edit page to be something like:
SolarSystem 1
| -- Planet a form
| -- Planet b form
| -- Add new planet?
SolarSystem 2
| -- Planet c form
| -- Planet d form
| -- Planet e form
| -- Add new planet?
SolarSystem 3
| -- Planet f form
| -- Add new planet?
That is, it lists out the solar systems and allows the user to add new planets
or edit an existing planet in a given solarsystem. In this example, SolarSystem
1
has planets a,b. The user can edit planet a,b. The user can also add a new
planet to this solar system (Planet x, for example).
In my views, I can do something like:
def displayform(request):
PlanetFormSet = inlineformset_factory(SolarSystem, Planet, extra=1)
formset = PlanetFormSet(queryset=SolarSystem.objects.all())
return render_to_response(... {"formset":formset}, ...)
But I don't quite understand how the template should be written. The logic
should be something like:
<form>
{% for solarsystem in solarsystems: %}
<span> Edit this solar system: {{ solarsystem.name }} </span>
{% for planetform in formset: %}
{{ form }}
</form>
The problem with that is how do I get solarsystem name from the formset and
then group the planet's forms based on that solarsystem? How would Django know
which
planetform goes with which solarsystem when I do a form post?
