QUESTION
I'm working in Django 3.2 and graphene-django 2.15. I'm still learning how to use Graphene by the way.
Note: I'm not allowed to share all the code so I rewrote it for the purpose of this question. Please notify me if you've found any error unrelated to the question.
I have an Team model which has a Many-to-Many relationship with the default Django Group model:
...ANSWER
Answered 2022-Mar-05 at 12:12I found the solution.
At first, I thought there was something related to graphene, especially these InputObjectTypes, I didn't get correctly.
But the issue is actually very simple.
The GroupInput is expecting a single value, which it an ID.
QUESTION
For Example: If the user is member of the group, response would contain all the group information including members of the group, else response will only contain the count of members in group. I'm using graphene-django and need to return this data from a query schema.
...ANSWER
Answered 2021-Jul-02 at 17:07Your GraphQL/Graphene schema will need to contain both fields, since the schema cannot conditionally change depending on the user, but you can conditionally choose to populate those fields in the response based on what the user should access.
For example:
QUESTION
I've built a Django API that uses django-graphql-auth and django-graphql-jwt packages to implement authentication. I followed the package's documentation and got everything to work and everything is working from my Angular UI. The only issue is that even requests made from Postman without the Authorization header, are able to fetch the data from the graphql API.
This is my Django project's settings.py

Answered 2021-May-30 at 06:24You should add the login_required decorator to your queries and mutations resolvers. Like this:
QUESTION
- I am using graphene-Django based backed
- Using Relay Node-based query
- Write REST-based CRUD operations using fetch API in react.
- Simple GraphQL queries that involve fetching a list or single item from the server.
- Able to write GraphQL queries on GraphiQL
- fetch a list of items from the server with pagination, that fetches say 10 items and the option to go to the first page, last page, Prev Page, and Next Page.
- few examples would help

ANSWER
Answered 2021-May-24 at 18:10The problem seems to be that graphene-django only has version 2.15.0 according to PyPI https://pypi.org/project/graphene-django/. But for some reason in this commit of the library django-graphql-jwt it asks for
a version 3.0.0b1. Which I think is the issue that shows in your log:
QUESTION
I am using Django as back-end with graphene-django serving the front-end. I am new to both django and graphene so I am not sure what is the best approach to achieve field-level permissions with no code repetition in this set-up. For example, if my model is:
...ANSWER
Answered 2021-May-10 at 06:50You're not going to find a stable/popular package for this, as it's not a design that a database can support well.
You cannot link (Foreign Key) a field and a table, you can only link two tables using a field. Therefore, any work to determine whether a row in a table has access to a field in another table, will be costly and error prone.
The best you could do, is to write a service layer that sits in between a resolver and a model that nullifies fields a user has no access to. You pass it the user (info.context.user) and a model, and it does a separate query to a field permissions model, fetches the record and nullifies each field according to permissions.
This inherently means each field needs to be nullable in order to support the permissions, complicating the frontend - it's a lot of work...
A better approach if your business logic allows it, is to group those fields into models, that can then be tied to "roles" or groups. So if this were medical data in a hospital:

QUESTION
I just started working with GraphQL, Django and Graphene.
I was attempting to import GraphQLView and DjangoObjectType from graphene_django
but it always says
unresolved reference
I did already installed the needed modules with pip install graphene-django==2.8.2, and the Virtual environment is up and running.
ANSWER
Answered 2021-Apr-30 at 12:10To solve the issue:
- navigate to your preferences (settings)
- go to 'Project'
- python interpreter
- click add on the packages list
- in the package manager search for
graphene_django - install -> apply
and you should be good to go.
QUESTION
For my current project (stack = Django + API + Vuejs), up to now I used GraphQL for my API (over Django, with graphene-django). But this library and other linked one (such as the one that handles JWTs) are quite abandoned, with bugs and weird things so to be more confident in the future I decided to switch to the well-known Django DRF.
The thing is, I'm now quite used to GraphQL system of queries and mutations, which is (maybe because I'm used to it) quite simple in its design and when it comes to start with DRF, I feel kinda lost.
Indeed, I think I understood the easiest way is to use both ModelSerializer and ModelViewSet but... I feel it's hiding lots of things under the hood. Like it has default methods (list(), retrieve(),...).
What if I want to controll all this by defining only the necessary ? Moreover, I have really specific needs.
For instance, update is not just giving all the arguments, update the model and TADAAA. For specific fields I have to perform specific actions. (e.g.: if a particular field is modified, send a mail,...)
Maybe the best way for my use case is to use simple views, I mean, like it is explained in the Trade-offs, using function based views might be the closest way to what I did with GraphQL ?
1 function = 1 view (URL) ?
Is that it ?
Thanks in advance for your clarifications.
...ANSWER
Answered 2021-Jan-31 at 12:36Having explored DRF a little more, I've come to the idea that what is the closest to GraphQL approach (lots of custom methods for me) is to use Function Based Views. Indeed, there is no hidden behavior or API methods behind this and I have complete control on the API.
Yes, there is extra work needed : writing the URLs myself for instance but, "Explicit is better than implicit".
So 1 URL = 1 mutation/query for me. And I execute the same work behind.
QUESTION
Graphene-Django docs note that you can pass graphiql=False when instantiating the GraphQLView if you do not want to use the GraphiQL API browser. However, I'd like to keep the GraphiQL API browser available, and merely restrict who has access to it. How can that be done?
For instance, how would I make it so that only "staff" users (who can access the Admin site) have permission to access the GraphiQL browser?
...ANSWER
Answered 2021-Jan-25 at 21:41You can extend the Graphene-Django GraphQLView and override its can_display_graphiql method (defined here) to add this sort of logic.
