I'm trying to solve a problem, but I have no idea how to face it. I need some help :-)

I have a model hierarchy like this:

class Task(models.Model):

name = models.CharField(max_length=255)

number_of_steps = models.IntegerField()

class StepGroup(models.Model):

task = models.ForeignKey(Task)

init_date = models.DateField()

class Step(models.Model):

group = models.ForeignKey(StepGroup)

name = models.CharField(max_length=255)

I must write a dialog where I create a number of Step Groups. An InlineFormSet looks the way to go, but as there are two levels of nesting, I don't know how to do that.

Besides, I need the usual stuff with forms: error control (form.name_of_field.errors), autopopulation when editing the Task, etc, so doing it manually with javascript and server-side handling of the POST request would be too complicated and error-prone.

This is the way I need the form (the number of steps in each group is set by the "number_of_steps" field in the Task model):

+-----------------------------------+

| STEP GROUP 1 |

| |

| Init date: _____________ |

| |

| Step 1: ________________ |

| Step 2: ________________ |

| Step 3: ________________ |

| |

+-----------------------------------+

| STEP GROUP 2 |

| |

| Init date: _____________ |

| |

| Step 1: ________________ |

| Step 2: ________________ |

| Step 3: ________________ |

| |

+-----------------------------------+

| |

| +-------------------+ |

| | Create step group | |

| +-------------------+ |

+-----------------------------------+

Please, any kind of help, suggestion or link will be very appreciated :-)

Could anybody help me with this problem, please? I know it's not very polite to ask twice, but I'm stuck on this, and I really need to solve it.

Excuse me for the insistence.

it looks like you need nested inlines, which I believe is not possible yet (https://code.djangoproject.com/ticket/9025)

in the meantime you can try using this (https://github.com/Soaa-/django-nested-inlines)
