hi I am a beginner with python and django and am writing my first application.I need to retrieve some objects of my model class created at different minutes in an hour.The class stores a datetime value in a 'creationtime' ( DateTimeField )and have an associated 'subject' string which can get repeated in many objects(ie object has one to many relation with subject).Only the 'creationtime' is unique for an object. How can I get a unique object using MyModel.objects. get()? When I checked the lookup docs ,it says it cannot do lookup on hour or minute ,but only on year,month,day.. Also I want to display the details of a single object.Do I need to create a unique slug? Is it possible to create a slug from DateTimeField 's value? (The prepopulated_fields in ModelAdmin doesn't accept DateTimeField and ForeignKey ..so I am not sure if I can use it in slug field). Also, how should I create the get_absolute_url for the class? If someone can give any pointers
