Django foreign key relation in template
If you review the foreign key documentation, if you have a relationship like
Doc -> has many DocImages
you need to define your foreign key on the DocImages class like so:
class DocImage(models.Model): property = models.ForeignKey(Doc, related_name='images')
If you don't set related names, you can access the DocImages from the Doc like:
Doc.docimage_set.all()
Docs on Related Objects
But setting related_name
in the property field lets you do
Doc.images.all()
Just make sure whatever you pass to the template in the view context matches what is used in the template, e.g.
# in the viewreturn render_to_response('mytemplate.html', { 'mydoc' : doc, 'mydocimage' : img }
This can then be used in the template as follows:
# and in your template to get the images attached to the document{% for i in mydoc.images.all %} ...{% endfor %}# or to get the document the image belongs to{{ mydocimage.property.date_added }}
- first you iterate over the result
- the images related to a Doc are retrieved by the images property of doc which is generated from the related_name attribute in the ForeignKey
code:
{% for doc in result %} {% for docimage in doc.images.all %} {{ docimage.image.url }} {% endfor %}{% endfor %}
