Body
<p>I have a Django app with three models which use ContentTypes and Generic to try and allow the Task model to have a ForeignKey to either of the other two models using <a href="https://stackoverflow.com/questions/881792/how-to-use-dynamic-foreignkey-in-django">How to use dynamic foreignkey in Django?</a> as a guide (although I'll admit that I have no clue what's going on with this approach).</p> <pre><code>class Task(models.Model): date = models.DateTimeField(null = True) day = models.IntegerField(null = True) task = models.CharField(max_length = 100, null = False) owner = models.CharField(max_length = 25, null = True) notes = models.CharField(max_length = 250, null = True) isDone = models.BooleanField(default = False, null = False) content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() maintenance = generic.GenericForeignKey('content_type', 'object_id') class Maintenance(models.Model): startMonth = models.CharField(max_length = 15, null = False) startYear = models.IntegerField(null = False) location = models.CharField(max_length = 20, null = False) mode = models.CharField(max_length = 20, null = False) taskRef = generic.GenericRelation(Task) class Template(models.Model): name = models.CharField(max_length = 25, null = False) location = models.CharField(max_length = 20, null = False) mode = models.CharField(max_length = 20, null = False) taskRef = generic.GenericRelation(Task) </code></pre> <p>Normally if Task just has a normal ForeignKey to Maintenance, I can get all the Tasks connected to any given Maintenance with Maintenance.task_set.all() but with this dynamic foreignkey system that function doesn't work. Does anyone know of an alternative function call to achieve this affect?</p>

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.
