Django admin - how to save inlines?

问题

I need to override save method of inlines in admin. While saving photos, I need to add user id to DB column. I cant make it in model because there is no request data there. How can I do it in admin, to somehow get nad set user id?

I believe the save_formset method on ModelAdmin is what you should use:

class ArticleAdmin(admin.ModelAdmin):
    def save_formset(self, request, form, formset, change):
        instances = formset.save(commit=False)
        for instance in instances:
            instance.user = request.user
            instance.save()
        formset.save_m2m()

I'm relatively new to django (1.8) and using the above override:

    def save_formset(self, request, form, formset, change):
    instances = formset.save(commit=False) # gets instance from memory and add to it before saving it
    for obj in formset.deleted_objects:
        obj.delete()
    for instance in instances:
        for form in formset: # cleaned_data is only available on the form, so you have to iterate over formset
            instance.modified_by = request.user
            instance.created_by = request.user
            instance.lowercase_enum_value_en = form.cleaned_data['enum_value_en'].lower()
            instance.save()
    formset.save_m2m()

i.e. adding to it before saving the instance and form, however when the user enters 2 lines it always saves the last cleaned_data['enum_value_en'].
