QUESTION
I'm currently using Python & Django with Graphene to model my Graphql backend. My question is similar to this one on Graphene's repo https://github.com/graphql-python/graphene/issues/431. I'm also using graphene_django_optimizer library to improve performance.
However I'm having a hard time understanding how to apply @syrusakbary proposed solution to my problem in my current scenario. Any help would be much appreciated
This is the query I wanna execute
...ANSWER
Answered 2021-Aug-09 at 11:32It sounds like you want to modify the sessions
field on your TrainingType
to add a new argument, and to add a resolve_sessions
method to the class.
Based on what I can see in your question, it'd be something like this:
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
Is there a way to add a value to an existing graphene.Enum
?
I want to use graphene-sqlalchemy sort_enum() functionality and to add additional functionality of my own - TOTAL_COUNT_ASC
and TOTAL_COUNT_DESC
that will enable sorting by total count, but I can figure out how to do it. Directly adding the fields to the graphene.Enum doesn't work:

I'm using Graphene package in my Flask app (https://github.com/graphql-python/graphene) and graphene-file-upload (https://pypi.org/project/graphene-file-upload/). I need to receive a file through a mutation as bellow:
...ANSWER
Answered 2020-Oct-22 at 01:43Did you import Upload from graphene_file_upload.scalars? You also need to make sure you fix the view function you hook up to your /graphql view
QUESTION
I found out something confusing about graphql-core
python library and wanted to know if maybe this could be a bug or if I'm missing something and this is an expected behavior.
This is my example.py
file. It only has one resolver that raises an error.
ANSWER
Answered 2020-Sep-06 at 23:50It was finally a bug, reported to the library owners and they've fixed it here.
QUESTION
I'm building an API with Django, I want to query the Github GraphQL API, and I found this GraphQL client for python that suits my needs.
But now, I'm wondering, where is the proper place to initialize such a client inside my Django App? inside the request? in the apps.py? in views.py? any guidelines will be appreciated! here is my current Django Project folder structure:
...ANSWER
Answered 2020-Jun-22 at 16:39As per definition a graphql client needs it's own configuration, modules and error handling I would suggest you to create a namespace adjacent to your other projects. Django uses the concept of Applications which is providing seperated configuration, logging and error handling for this case. You define additional Applications in your project in your settings.py
in INSTALLED_APPS
(Docs). Your project structure would then look smth like:
QUESTION
I'm following the graphql python tutorial at https://www.howtographql.com/graphql-python/4-authentication/. It worked fine for the first 3 sections, but in the Authentication section I've run into this problem.
I am learning python, don't know Django or graphql, so it's a lot to digest all at once, but it was going ok until now. Also not sure what relevant bits to include here.
I followed all the instructions. When I go to my local project site at localhost:8000/graphql/
, I get
TypeError at /graphql/
__init__() missing 1 required positional argument: 'get_response'
Here is the relevant snippet of my settings.py:

I am having some issues with my django app since updating my dependencies. Here aer my installed apps:

Answered 2020-Jan-04 at 08:55Ok I was able to fix it by downgrading graphql-core==3.0.1
to graphql-core<3
(and all the depencencies).
I must have missed the errors when performing pip install -r requirements.txt
