    <p>Having something like</p> <ul> <li>created_by </li> <li>created_date </li> <li>modified_by</li> <li>modified_date</li> </ul> <p>Would be a very common pattern for a lot of tables.</p> <p>1) You can set created date automatically (but not others) in model.py with</p> <pre><code>created_date = models.DateTimeField(auto_now_add=True, editable=False) </code></pre> <p>2) You could do created/modified dates (but not by/user as don't have request context) in model.py with</p> <pre><code>def save(self): if self.id: self.modified_date = datetime.now() else: self.created_date = datetime.now() super(MyModel,self).save() </code></pre> <p>3) You could set the created/modifed date and by in admin.py - but this doesn't deal with non admin updates</p> <pre><code>def save_model(self, request, obj, form, change): if change: obj.modified_by = request.user obj.modified_date = datetime.now() else: obj.created_by = request.user obj.created_date = datetime.now() obj.save() </code></pre> <p>4) And the final place would be in the view.py which can do all 4, but doesn't cover admin updates.</p> <p>So realistically have to have logic spread out, at a minimum repeated in 3 &amp; 4 (or a method on the model called from both, which will be missed)</p> <p>Whats a better way? (I've been working with python/django for a couple of days so could easily be missing something obvious)</p> <ul> <li>Can you do someting like @login_required e.g. @audit_changes</li> <li>Can you get access to the request and current user in the model and centralise logic there?</li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
