    <p>There's a simple hack to do this, but it's not a general solution and requires modifying every <code>ModelAdmin</code> which you want to support this. Maybe there is a general way to do this, but I've not spent the time to solve it on a general level.</p> <p>The first step is to write a custom <code>FilterSpec</code> for the filter (see Harley's post for links that will help) which saves the chosen filter value in the session (and deletes it when no longer wanted).</p> <pre><code># in cust_admin/filterspecs.py from django.contrib.admin.filterspecs import FilterSpec, ChoicesFilterSpec class MyFilterSpec(ChoicesFilterSpec): def __init__(self, f, request, params, model, model_admin): super(MyFilterSpec, self).__init__(f, request, params, model, model_admin) if self.lookup_val is not None: request.session[self.lookup_kwarg] = self.lookup_val elif self.lookup_kwarg in request.session: del(request.session[self.lookup_kwarg]) # Register the filter with a test function which will apply it to any field # with a my_filter attribute equal to True FilterSpec.filter_specs.insert(0, (lambda f: getattr(f, 'my_filter', False), MyFilterSpec)) </code></pre> <p>You must import the module this is in somewhere, for example your <code>urls.py</code>:</p> <pre><code># in urls.py from cust_admin import filterspecs </code></pre> <p>Set a property on the field you want to apply the filter to:</p> <pre><code># in models.py class MyModel(models.Model): my_field = Models.IntegerField(choices=MY_CHOICES) my_field.my_filter = True </code></pre> <p>In a custom <code>ModelAdmin</code> class, override the <code>change_view</code> method, so that after the user clicks <strong>save</strong>, they are returned to the list view with their filter field value added to the URL.</p> <pre><code>class MyModelAdmin(admin.ModelAdmin): def change_view(self, request, object_id, extra_context=None): result = super(MyModelAdmin, self).change_view(request, object_id, extra_context) if '_save' in request.POST: if 'my_field__exact' in request.session: result['Location'] = '/admin/myapp/mymodel/?my_field__exact=%s' \ % request.session['my_field__exact'] return result </code></pre>

    1. CODoes this mean that every time you view the model's admin page it will be filtered? Or does it just remember the filter you've applied for a session?

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.
