Re: wondering how to do something similar to save_model for inline.

[Timboy]

Good call on the ModelAdmin spot. (user contacted me by email to see
if I had a solution yet.)

I got the formset.save() from here:
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-method
saying: "If your formset contains a ManyToManyField, you'll also need
to call formset.save_m2m() to ensure the many-to-many relationships
are saved properly."

Works now just had it in the wrong spot. thx!

(Where was it confirmed by another user?  I don't see that.)

The doc list "save_formset" under "ModelAdmin methods" yet you seem to have
added it to your inline admin class.  I also don't see any indication in the
traceback you posted that your custom method is being called, which leads me
to think where you have put it is not where it needs to be in order for it
to be called.

(Also you changed formset.save_m2m() from the example in the docs to
formset.save().  I doubt that this change is correct.)

Still no solution to this. It has been confirmed by another user. Is

Re: wondering how to do something similar to save_model for inline.

Great link. I was really excited to try it.

Here is my new inline:
class rentalInline(admin.TabularInline):
model= Rent
extra = 3
raw_id_fields = ('movie',)
exclude = ['rented_by']

def save_formset(self, request, form, formset, change):
instances = formset.save(commit=False)
for instance in instances:
instance.rented_by = request.user
instance.save()
formset.save()

Take a look at the save formset method:

wondering how to do something similar to save_model for inline.

[Timboy]

I have an admin object where I want to pass in the request.user on
save. It works fine in my normal admin class but not for the inline
version.

(works fine here):
class RentAdmin(admin.ModelAdmin):
exclude = ['rented_by']
list_display = ('renter', 'movie', 'late', 'owed', 'paid',
'due_date', 'rented_by')
sort_by = '-due_date'
raw_id_fields = ('renter', 'movie')

(but not here):
class rentalInline(admin.TabularInline):
model= Rent
extra = 3
raw_id_fields = ('movie',)
exclude = ['rented_by']

def save_model(self, request, obj, form, change):
if not change:
obj.rented_by = request.user
obj.save()

Any help would be appreciated.
