add an object along with it's related objects in the same form in django admin

Question

I have these models:

class Gallery(models.Model):
   HeadImage = models.ImageField(upload_to="gallery") 

class Image(models.Model):
   Image = models.ImageField(upload_to="gallery")
   Gallery = models.ForeignKey(Gallery, related_name='images',blank=True)

class Agency(models.Model):
   # some fields ...
   Gallery=models.ForeignKey(Gallery)

Now I want to, when adding an Agency, instead of showing just an stupid combobox for Gallery field, I have these things:

A file upload for HeadImage field in Gallery model and a set of file uploads for Image field in Image model. Some thing like adding an object(Agency) with it's related objects(Gallery related to Agency and Image related to gallery)in one form. How can I do this? I didn't find any solution after googling a lot, that sounds an awful problem.

edit: I mean save an Glaaery with a set of it's images and save agency with it's gallery at the same form.

thanks for any help

@pbm Inlines won't work, because it's the ui for the foreign key from Agency to Gallery that @Asima does not like. — Alasdair

Personally, I think you are trying to do too much in the Django admin. It looks to me like you should write your own view, then you can display all the forms you wish. — Alasdair

U know,I think it's a bad idea to first add an gallery then add a set of images,then go to agency form and add an agency with that gallery,I wanna have gallery and a set of images in Agency add form,is it a hard scenario?well,how can I write a view? — Asma Gheisari

off course I think having a 2 step form is a good idea,too. I mean user can add an gallery in first step and in second step add a agency for that,is it possible,of course I've found some references in internet but no one were useful. — Asma Gheisari

As I said in the comment above, you're trying to do too much in the Django admin.

Looking at your other question, you are familar with the tools you need to write your own view. Define model forms for your models. Put them in the same form tag in your template. If the form is valid, save with commit=False then fix up the foreign keys.

Here's a skeleton view for adding an Agency and a Gallery together. You could easily add a formset of images at the same time.

def add_agency(request):
    if request.method == "POST":
        agency_form = AgencyForm(data=request.POST, prefix="agency")
        gallery_form = GalleryForm(data=request.POST, prefix="gallery")
        if agency_form.is_valid() and gallery_form.is_valid():
            gallery = gallery_form.save()
            agency = agency_form.save(commit=False)
            agency.gallery = gallery
            agency.save()
            return HttpResponseRedirect(next_url)
    else:
        # left as an exercise

If you want a two step form, I recommend you look at formwizard. It's a separate app for Django <=1.3.X], and included in Django >=1.4.

I created my own view for it,but now the problem is that it is not like other admin forms,it doesn't have a change list,it doesn't have a link in home page to add and change ... how can I implement theme?

Alasdair Over a year ago

You might be able to the ModelAdmin.add_view(), ModelAdmin.change_view() or ModelAdmin.get_urls() hooks to integrate your view into the admin. For more info see the admin docs.

first of all,thank U for your helps.after googling alot,now I think adding a field for HeadImage and a formset for Image to AgencyModelAdmin and overriding save method to save Gallery,Images and Agency at once should be most rewarding than writing my own view and I won't lose admin facilities.but I don't know yet if it's possible to add another form or formset like extra fields to a model admin or not.is it possible?

Alasdair Over a year ago

You can override ModelAdmin.form, but I don't think it's easy to add 'formset like extra fields', so would recommend using the add_view and change_view hooks instead. Good luck!
