params['blog_posts'] = Content.objects.get(user = blah)
params['other_vars'] = "other stuff"
params['votes'] = 4245
if request.GET.get("format") == "json":
response = json.dumps(params)
return HttpResponse(response)
else:
return render_to_response("posts.html", params, RequestContext(request))
In my template, I do stuff like this:
{% for p in blog_posts %}
The author is: {{ p.user.get_profile.about_me }}
{% endfor %}
As you can see, I really utilize the Django's foreign key/database models. 开发者_运维技巧 The problem is...how do I shoot all of these foreign models to JSON?
Even if I serialize blog_posts
using django.core.serializers
, the JSON won't contain the .user
model, and of course won't contain the .get_profile
model.
One option is to have your model class itself contain the knowledge of how to serialize itself:
class MyBaseModel(BaseModel):
def serialize():
abstract # this will throw an error if it's called without being overwritten
class Post(MyBaseModel):
title = db.stringProperty()
body = db.textProperty()
user = db.referenceProperty(User)
# etc etc etc
def serialize(self):
return {
'title' : self.title,
'body' : self.body,
'user' : self.user.serialize()
# etc
}
