On my Django-mongodb model, I would like to have an object with a listField containing reference to other objects. Here is an example of what I want to achieve :
models.py
class Comment(models.Model):
title = models.CharField(max_length=50)
body = models.CharField(max_length=50)
class Post(models.Model):
name = models.CharField(max_length=50)
commentList = ListField(models.ForeignKey(Comment))
api.py (Tastypie Resources)
class CommentResource(MongoResource):
class Meta:
object_class = Comment
queryset = Comment.objects.all()
resource_name = 'comment'
authentication = Authentication()
authorization = Authorization()
class PostResource(MongoResource):
commentList = ListField(models.ForeignKey('CommentResource', 'commentList') #Wrong but just the expression of my incomprehension.
class Meta:
object_class = Post
queryset = Post.objects.all()
resource_name = 'post'
authentication = Authentication()
authorization = Authorization()
In this example, the field "commentList" contains a list of "Object ID" referencing "Comment" objects. If nothing is done, an HTTP GET on my "Post" resource will give me:
[...],
objects: [
{
id: "4f47b159c789550388000000",
name: "Hello World",
commentList: "[u'4f47b14ec789550387000000']",
resource_uri: "/api/v1/post/4f47b159c789550388000000/"
}
]
What I would love to get is this :
[...],
objects: [
{
id: "4f47b159c789550388000000",
name: "Hello World",
commentList:
[
comment:{
title : "My comment title",
body : "It would be great if tastypie-nonrel could do this!",
resource_uri: "/api/v1/comment/454f4v59c789550388051486/"
}
],
resource_uri: "/api/v1/post/4f47b159c789550388000000/"
}
]
My question is : How can I resolve the reference to objects Comment and make it available with a API call to the ressource Post?
If this is not possible, what would be the best way to design my non-relational data model so that a Post can contain multiple Comment, but that Comment can alo be accessed on its own and updated independently?
Thanks a lot for your help!!
