Manipulating Data in Django's Admin Panel on Save

Question

Ok, so here\'s the skinny:

# models.py
class Article( models.Model ):
    title           = models.CharField( max_length = 255 )
    author          = models         


        

Answer 1

From the Django Docs:

ModelAdmin.save_model(self, request, obj, form, change)

The save_model method is given the HttpRequest, a model instance, a ModelForm instance and a boolean value based on whether it is adding or changing the object. Here you can do any pre- or post-save operations.

For example to attach request.user to the object prior to saving:

class ArticleAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        obj.save()

Answer 2

class ArticleAdmin( admin.ModelAdmin ):
    fields  = [ 'title', 'body' ]
    form    = ArticleAdminForm

    def save_model(self, request, obj, form, change):
         obj.author = "name Here"
         obj.save()
