问题 I'm rebuilding a former Django REST API project as a GraphQL one. I now have queries & mutations working properly. Most of my learning came from looking at existing Graphene-Django & Graphene-Python code samples. There seem to be a lot of inconsistencies amongst them. In some it was suggested that the GraphQL queries should be placed in schema.py whereas the mutations should be placed in mutation.py . What I'm thinking makes more sense is to instead have these two files hold their respective

问题 I am doing the graphene tutorial on filtering with relay from: http://docs.graphene-python.org/projects/django/en/latest/filtering/ where the user is restricted to query objects that they previously created. I am using graphene 2, django 2, and django-filter 1.11. class AnimalFilter(django_filters.FilterSet): # Do case-insensitive lookups on 'name' name = django_filters.CharFilter(lookup_expr=['iexact']) #changed this to work class Meta: model = Animal fields = ['name', 'genus', 'is

问题 I have a simple django model with a calculated property field clicks . The model looks like this: class Link(models.Model): url = models.URLField() @property def clicks(self): """ Property does some calculations and returns a list of dictionaries: """ # removed calculation for simplicity return [{'dt': 1, 'clicks': 100}, {'dt': 2, 'clicks': 201}] I want to make this model accesible in my graphql endpoint. So I created the following Types and Query: class Stats(graphene.ObjectType): clicks =

问题 Currently I am investigating using graphene to build my Web server API. I have been using Django-Rest-Framework for quite a while and want to try something different. I have figured out how to wire it up with my existing project and I can test the query from Graphiql UI, by typing something like { industry(id:10) { name description } } Now, I want to have the new API covered by Unit/integration tests. And here the problem starts. All the documentation/post I am checking on testing query

问题 I have 2 databases I want to query from, but I only get results from one. I'm using mongoengine with python and graphene (it's my first time). I've exhausted my search and I don't understand how I can resolve this issue. Here is my code: import graphene from mongoengine import Document, connect from mongoengine.context_managers import switch_collection from mongoengine.fields import ( StringField, UUIDField, IntField, FloatField, BooleanField, ) from graphene_mongo import

问题 Hi guys, so i'm trying to use graphQL queries in django. Basically i have two apps, my 'api' app which contains everything i need to make the queries and another one called 'frontend' from which i call the api to use these queries. I can use the GraphQL view to type queries in it and it works perfectly, but whenever i try to make the query, i get this : "OrderedDict([('users', None)])" Result of my query in the GraphQl view And for the code : In 'api' my schema.py : import graphene import

问题 Let's say I have a model: class Employee(models.Model): first_name = models.CharField(max_length=40) last_name = models.CharField(max_length=60) salary = models.DecimalField(decimal_places=2) I want anyone to be able to access first_name and last_name but only want certain users to be able to read salary because this is confidential data. And then I want to restrict write/update for salary to an even different kind of user. How do I restrict field read/write/update depending on the request

问题 I have some django model generic relation fields that I want to appear in graphql queries. Does graphene support Generic types? class Attachment(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') file = models.FileField(upload_to=user_directory_path) class Aparto(models.Model):

问题 I'm a newbie for the graphene and I'm trying to map the following structure into a Object Type and having no success at all { "details": { "12345": { "txt1": "9", "txt2": "0" }, "76788": { "txt1": "6", "txt2": "7" } } } Any guidance is highly appreciated Thanks 回答1: It is unclear what you are trying to accomplish, but (as far as I know) you should not have any arbitrary key/value names when defining a GraphQL schema. If you want to define a dictionary, it has to be be explicit. This means

问题 I've successfully used Graphene-Django to successfully build several GraphQL calls. In all of those cases I populated, in whole or in part, a Django model and then returned the records I populated. Now I have a situation where I'd like to return some data that I don't wish to store in the Django model. Is this possible to do with Graphene?
