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.

Take a look at the save formset method:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#save-formset-self-request-form-formset-change

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()

I am still getting the same issue:

This is your database error..

[Timboy]

DB is sqlite3. Deleted DB file syncd and still same traceback.
here is proper traceback paste: http://dpaste.com/103517/

[Timboy]

Still no solution to this. It has been confirmed by another user. Is
it a bug?

(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.)

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!
