neo4django

问题 I am trying to create a REST API with Neo4j and Django in the backend. The problem is that even when I have Django models using Neo4Django , I can't use frameworks like Tastypie or Piston that normally serialize models into JSON (or XML). Sorry if my question is confusing or not clear, I am newbie to webservices. Thanks for you help EDIT: So I started with Tastypie and followed the tutorial on this page http://django-tastypie.readthedocs.org/en/latest/tutorial.html . I am looking for

问题 I'm trying to get an object from my neo4j database using neo4django >>> # There is a single Person object in the database, so I get a value >>> slug=Person.objects.get().name_slug >>> print(slug) doe-john >>> # ok, it's there >>> p=Person.objects.get(name_slug=slug) Traceback (most recent call last): File "<console>", line 1, in <module> File "/[...]/src/neo4django/neo4django/db/models/manager.py", line 37, in get return self.get_query_set().get(*args, **kwargs) File "/[...]/lib/python2.7

问题 Considering my previous question, I try to implement what I need. The following is the content of a django app models.py. from neo4django.db import models from neo4django.auth.models import User as AuthUser class MyManager(models.manager.NodeModelManager): def filterLocation(self,**kwargs): qs = self.get_query_set() if 'dist' in kwargs: qs = qs.filter(_where_dist=kwargs['dist']) elif 'prov' in kwargs: qs = qs.filter(_where_prov=kwargs['prov']) elif 'reg' in kwargs: qs = qs.filter(_where_reg

问题 When trying to purge neo4j (1.8.2) with the cleandb extension (for neo4j 1.8), it fails: [path] ? curl -v -X DELETE 'http://localhost:7475/db/cleandb/12sE$lkj3%' * About to connect() to localhost port 7475 (#0) * Trying 127.0.0.1... * Connected to localhost (127.0.0.1) port 7475 (#0) > DELETE /db/cleandb/12sE$lkj3% HTTP/1.1 > User-Agent: curl/7.29.0 > Host: localhost:7475 > Accept: */* > < HTTP/1.1 500 Internal Server Error < Content-Length: 0 < Server: Jetty(6.1.25) < * Connection #0 to host

问题 I was trying to create my model MyUser extending neo4django.auth.models.User, so I can use the underlying authentication system. The problem is I want create also a superclass from which derive many methods and attributes that are very common for my different kind of nodes. I did this: from neo4django.auth.models import User as AuthUser class MyBaseModel(models.NodeModel): .... class Meta: abstract = True class MyUser(MyBaseModel,AuthUser): ... but any operation on the model gives me

问题 I've seen that relationship properties are not yet implemented in neo4django. The workaround exposed in this thread is to have a new node type for each relationship with a property. I can't afford too much calculations so I don't want to use this technique. While reading the source code I've seen, as the docstring of the Relationship class, this : """Extend to add properties to relationships.""" My question is, how to do that ? Where to start to add at least one property ? Thanks 回答1: Despite

问题 I was just trying neo4django's very own example, namely from neo4django.db import models class Person(models.NodeModel): name = models.StringProperty() age = models.IntegerProperty() friends = models.Relationship('self',rel_type='friends_with') However, when running python manage.py syncdb I get the following error: AttributeError: type object 'Model' has no attribute '__metaclass__' Any ideas? (I would use label "neo4django" here in Stackoverflow, but it does not let me create a new label

问题 So I've trying to model a small user-group relationship in Neo4j with Django. I am currently employing the Neo4django python package seen here. Now, I have nodes representing my users, and nodes representing my groups, and relationships that link them indicating membership. What I'm hoping to also do in the near future is add properties to this relationship such as date_joined. I looked around but there isn't too much documentation on how to achieve this. I'm sure there is a way of doing it,
