    <p>Is there a way of returning items from a database in django-nonrel, using 'order_by' on a foreignkey?</p> <p>Full details are as follows:</p> <pre> #Models.py class Post(models.Model): article = models.TextField(help_text='Paste or type HTML in here') pub_date = models.DateField() .... class TagItems(models.Model): title = models.CharField(max_length=200) .... class TagRel(models.Model): the_post = models.ForeignKey('Post') the_tag = models.ForeignKey('Tag') </pre> <p>TagRel defines a ManytoMany relationship between Post and TagItems classes.</p> <p>I am wanting to get a list of articles for each tag.</p> <pre> #Desire output My tag -my first post -my second post My second tag - my other post - another post </pre> <p>All is good so far, as I use the following to filter the data:</p> <pre> def tagged_posts(): tag_items = TagItems.objects.all() li =[] for item in tag_items: tag_rel_item = TagRel.objects.filter(the_tag__pk = item.pk) li.append(tag_rel_item) return {'list_of_objects': li} </pre> <p>I am using db-indexer to define the filter part of the query in db-indexes.py. All this works fine but I want to order my posts by publication dates.</p> <p>Django docs tell me to use:</p> <pre> TagRel.objects.filter(the_tag__pk = item.pk).order_by('the_tag__pub_date') </pre> <p>But the order_by('the_tag__pub_date') part does not appear to be supported by django-nonrel.</p> <p>The following also works in normal Django:</p> <pre> TagRel.objects.filter(the_tag__pk = item.pk).order_by('the_post') </pre> <p>This works because the Posts are already sorted by date in the model.</p> <p>But this also does not appear to work in django-nonrel.</p> <p>So my question is how do I return my posts ordered by date (latest>oldest)?</p> <p>Thanks in advance</p>

    1. COI have the same question too. The workaround is the make a text field with the information, but I want to avoid that.

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.
