    copied!<p>I'm building a django tastypie api, and I have a problem with adding elements in <code>ManyToMany</code> relationships</p> <p>Example, models.py</p> <pre><code>class Picture(models.db): """ A picture of people""" people = models.ManyToManyField(Person, related_name='pictures', help_text="The people in this picture", ) class Person(models.db): """ A model to represet a person """ name = models.CharField(max_length=200, help_text="The name of this person", ) </code></pre> <p>resources:</p> <pre><code>class PictureResource(ModelResource): """ API Resource for the Picture model """ people = fields.ToManyField(PersonResource, 'people', null=True, related_name="pictures", help_text="The people in this picture", ) class PersonResource(ModelResource): """ API Resource for the Person model """ pictures = fields.ToManyField(PictureResource, 'pictures', null=True, related_name="people", help_text="The pictures were this person appears", ) </code></pre> <p>My problem is that I would like to have an <code>add_person</code> end point in my picture resource. If I use <code>PUT</code>, then I need to specify all the data in the picture If I use <code>PATCH</code>, I still need to specify all the people in the picture. Of course I could simply generate the <code>/api/picture/:id/add_people</code> URL and there I could handle my problem. The problem with that is that it does not feel clean.</p> <p>Another solution would be to generate the <code>/api/picture/:id/people</code> end point, and there I could do <code>GET</code>, <code>POST</code>, <code>PUT</code>, like it's a new resource, but I don't know how to implement this and it seems strange to create new people under this resource.</p> <p>Any thoughts?</p>
