python - How can I have the equivalent of django's admin inlines in a modelform? -

django's admin allows create form editing model , foreign keys, if i'm using modelform in own view, i'm having trouble accomplishing this. here's example in admin.py:

class vendorphotoinline(admin.stackedinline):   model = vendorphoto   = 3  class vendoradmin(admin.modeladmin):   inlines = [vendorphotoinline]  admin.site.register(vendor, vendoradmin) 

so in admin, can create vendor , add bunch of photos. non-staff, have form creating vendor, , i'd allow them upload photos admin.

i'm using modelform allows users create new vendors, of course, can't add photos @ point:

class vendorform(modelform):     class meta:         model = vendor 

how can achieve parity admin interface here? i'd settle solution works new vendor instances , allows uploading of number (say, 3), works existing instances , allows adding / deleting photos great too. help!

you can use inline formsets. documentation:

suppose have these 2 models:

from django.db import models  class author(models.model):     name = models.charfield(max_length=100)  class book(models.model):     author = models.foreignkey(author)     title = models.charfield(max_length=100) 

if want create formset allows edit books belonging particular author, this:

>>> django.forms.models import inlineformset_factory >>> bookformset = inlineformset_factory(author, book) >>> author = author.objects.get(name=u'mike royko') >>> formset = bookformset(instance=author) 

the inlineformset_factory takes care of things behind scenes, front-end part may find django-dynamic-formset jquery plugin useful.
