Retrieve all activities from Strava API to Python
I Already registered my API in my Strava Account and I Want to fetch all activities of the user. Here's my current snippet code: auth_url = "https://www.strava.com/oauth/token" activites_url = "https://www.strava.com/api/v3/athlete/activities" payload = { 'client_id': "xxxx", 'client_secret': 'xxxx', 'refresh_token': 'xxxx', 'grant_type': "refresh_token", 'f': 'json' } res = requests.post(auth_url, data=payload, verify=False) print("Authentication Status:", res.status_code) access_token = res.json()['access_token'] print('ACCESS TOKEN: ', access_token) #Prints '200' which is correct header = {'Authorization': 'Bearer ' + access_token} param = {'per_page': 200, 'page': 1} my_dataset = requests.get(activites_url, headers=header, params=param).json() print('DATASET: ', my_dataset) #This line returns: {'message': 'Authorization Error', 'errors': [{'resource': 'AccessToken', 'field': 'activity:read_permission', 'code': 'missing'}]} It says that the 'code' is missing. Is that the main and only reason that leads to Authorization Error? How do I Retrieved it? I'm Currently developing on localhost only. Access_token is not expired. -
Cannot access Django project homepage (Docker)

How to dynamically change static urls in an Angular application in every component
I have an Angular application that I am using alongside a Django application. In Django we have something like this src="{% static 'folder/file' %}" where we can change the static urls dynamically based on our environment. (Example, I can have static files pointing to my local machine vs I can have them deployed in AWS S3, changing it in one place in the application, will change it everywhere.) How can I implement something similar in Angular, where I can change the static_url dynamically based on the environment. I would like this to work on all the components within my application. Example: When using ng serve it could be /assets But when using ng build it would be https://s3_bucket_url/assets -
Django Channels Custom Middleware Not Being Called
With Django 4 and Channels 4 I have a middleware as follows from channels.middleware import BaseMiddleware class TokenAuthMiddleware(BaseMiddleware): async def __call__(self, scope, receive, send): print('asdf') headers = dict(scope['headers']) if b'authorization' in headers: # Fetch the token here token = headers[b'authorization'].decode().split(' ')[-1] scope['token'] = token return await self.inner(scope, receive, send) In my INSTALLED_APPS, I have channels and daphne near the top. I also have properly set ASGI_APPLICATION in my django settings. And in my asgi.py I have: os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'api.settings') application = ProtocolTypeRouter({ 'http': get_asgi_application(), 'websocket': TokenAuthMiddleware(AuthMiddlewareStack( URLRouter([ re_path(r'ws/agent/$', AgentConsumer.as_asgi()), ]) )), }) AgentConsumer is a channels consumer based on AsyncChannelConsumer Yet when I connect to the websocket (in this case, a raw python script using the websockets module), I don't think the middleware is being run. If I put a print statement in the class definition, I see it. But if I put it in __call__(), I never see the print statement. To add, I have AuthMiddlewareStack, but it seems like it's allowing even unauthenticated socket connections, meaning none of that middleware is being executed? Is there a reason it seems like the middleware is not being executed? -
How do I add dependencies that can't be installed with pip to my (django) project on Heroku?
I've come across multiple similar issues to this and I haven't seen a clear answer so I thought it best to ask here. I'm working on a django project, and one of the packages it uses requires PyMuPDF which in turn requires swig, which can't be installed with pip/add to requirements.txt. I'm trying to deploy this project to Heroku and this is causing it to fail. See the build error from Heroku below. PyMuPDF/setup.py: Finished building mupdf.

SQL Server FREETEXTTABLE query to mySQL
I got a Django project that was previously using a Sql Server database. I need to adapt it now for mySQL. I struggle to implement and find the equivalent for that raw sql using FREETEXTTABLE. If anyone could point me in the right direction on any documentation that would be greatly appreciated. Original SQL Server raw query sql = "select c.myKey, b.[KEY], b.RANK, a.article_appendix, c.article_appendix as article, c.title_en as t1_en, c.title_fr as t1_fr, a.title_en as t2_en, a.title_fr as t2_fr from [myapp_collectiveagreementsubarticle] a inner join (SELECT * FROM FREETEXTTABLE ([myapp_collectiveagreementsubarticle], ([content_en]), " + search2 + ")) b on a.myKey = b.[KEY] inner join [myapp_collectiveagreement] c on a.articleKey_id = c.myKey order by b.RANK desc" searchResult = Collectiveagreement.objects.raw(sql) -
Uploading multiple large files with django on Google App Engine -- how to do multiple requests
I'm trying to figure out how to load multiple large files (like 4K images) to Google Cloud Storage via django using the default admin interface. For example, I have a model with multiple images: MyModel(models.Model): image_1 = models.ImageField( null=True, upload_to="myapp/images" ) image_2 = models.ImageField( null=True, upload_to="myapp/images" ) However, if I enter data for this model in the admin interface, this causes an error if I load two large files that go over GAE's 32 MB post limit. I've tried using django-gcp and BlobField, but this also causes issues because the temporary uploads overwrite each other before transferring to Google Cloud Storage -- and it doesn't look like this is solvable with django-gcp out of the box. So right now I'm wondering if it's possible to break out upload into multiple POST requests -- that way each one can be a separate ImageField (if under 32MB) or BlobField, and I won't have any issues. Is there a way I can upload a model in multiple POSTs? -

Implementing an Abstract User Class in django implemented similarly to C++?
I am sorry but since I am not really experienced with py/django that much i will be making a parallel on c++ classes. I am trying to make a User Abstract class with two childs classes User_A and User_B, I want to call a User be it A or be without differentiating between them. a c++ equivalent to that would be: User *new_user = new User_A; new_user.send_user_data(); (send_user_data being the abstract fonction) But from what i found this doesn't seem to be possible, so my next idea was to make a User model and have a field referencing either User_A or User_B, but this doesn't seems to be possible either as I would need to seperate fields for each of them, which isn't what i want. I welcome any ideas, Thank you. -

Django bad choice for microservices
Spring boot is considered as the most suitable choice for microservices due to it's scalability, performance and bla.. bla.. bla.. but to create microservices we have to create a new project in spring boot for each microservice. On the other hand, django consists apps (which can be used as microservices) where each app can be configured to different databases and I think django is more structured on the projects based on microservices architecture. Then why django isn't considered most suitable choice for microservices architecture compared to spring boot ?? -

Are RunPython function in django migrations required when squashing commits if they are only modifying existing data?
I have a django project that needs migration squashing. All of the RunPython functions are moving data from one column to another after making some change. If it was just for moving old data and does not affect newly created records, do I need it or not while squashing migrations or creating them from scratch? Here is an example: # Adding the new field migrations.AddField( model_name='approvalrequest', name='club', field=models.ForeignKey(null=True, on_delete=django.db.models.deletion.CASCADE, to='members.club'), ) # RunPython function call migrations.RunPython(migrate_membership_to_enrollment, reverse_code=reverse_migration) # RunPython function def migrate_membership_to_enrollment(apps, schema_editor): ApprovalRequestModel = apps.get_model('approval_requests', 'approvalrequest') db_alias = schema_editor.connection.alias with transaction.atomic(): requests = ApprovalRequestModel.objects.using(db_alias).all() for request in requests: club = request.membership.club request.club = club request.save() # Deleting memberhsip field migrations.RemoveField( model_name='approvalrequest', name='membership', ), You can see we are making a change and moving existing data according to it. Now that it has been done and everyone is on the latest versions of migrations, can this method be removed altogether? -

How to deploy a django backend?

I have tried on railway as this said, but it shows the error message like: Nixpacks was unable to generate a build plan for this app. I guess the front end is not a problem so might be the backend. Our configuration steps are a bit confusing I'll put it below: Screenshot After all these mysterious steps I can start my backend locally. Please Help!! -
