Google Calendar OAuth 2.0 Error 403: access_denied
I have been trying to gain authorization from the Google Calendar API on my site so that I can access user calendar data. When I issue an HttpResponseRedirect from the desired view on my site via Django (to send the user to Google so they can provide the necessary permissions), the redirect works as expected. The issue is that on Google it's returning "error 403: access denied", along with a message stating that the developer must authorize my account before I can use the API (I'm trying to use a different Google account to log in for the purpose of testing). I've poked around the Google API site, but can't find where this authorization occurs. Any idea of where I might find this? Full Specific Error Message. -
DRF Protect user registration view
I have a following user view: class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer permission_classes = [NotSafeMethodAndAllowAny | permissions.IsAuthenticated] def get_queryset(self): if self.request.user.is_superuser: return User.objects.all() else: return User.objects.filter(id=self.request.user.id) @action(detail=False, methods=["get"]) def current(self, request, *args, **kwargs): return Response(self.get_serializer(request.user).data) As this is a ModelViewSet, it allows API users to create, list, update, delete the users. Don't mind the NotSafeMethodAndAllowAny permission. Now I want to somehow protect my API from the users using it like in a script. For example, when I submit the user registration form on my frontend (a separate React app), it should be accepted, but if someone posts to my api/user/ with random registration data like from Postman/curl/etc., I want it to be discarded. Is there a way for DRF to distinguish between those two types of requests? And possibly via some setting, so I can test it via Postman when in development, but when it runs in production, it would not accept automated requests. I want to prevent a situation where someone would create like a bazillion users in a matter of minutes. BTW: I use JWT for authentication, but for obvious reasons the registration/login endpoints do not require authentication. -

Cloudant local cache not syncing with local couch cache. Using python-cloudant

Remove the database exception error on a page reload
I am on Django Framework and implemented an interface where a user can do Insert and Update operations on a MySQL table. My table does not allow duplicates, so I display an Exception error to the user to let them know their request failed. However, when I reload the page the error message still get's displayed when it shouldn't. The message only disappears when I submit a successful request that has no duplicates. It seems like the error message keeps getting displayed because on page reload it is returning a POST request and it re-enters the duplicate key which spits out the Exception message. How can I stop this request from submitting twice, or is there a better approach to accomplish this? views.py def generate_student_info(request): # Retrieve inputted value current_student_name = request.POST.get('student_name') current_student_id = request.POST.get('student_id') # Read the table from the database connection = db.open_connection(read_only=False) sql_str = f"""SELECT * FROM {students_table};""" df = db.read(sql_statement=sql_str, connection=connection) # creating a formset insert_formset = formset_factory(StudentInfoForm, extra=0) formset = insert_formset(request.POST or None, initial=[{'student_id': df['student_id'][i], 'student_name': df['student_name'][i]} for i in range(len(df))]) context = {'formset': formset, 'db_error_message': '', 'display_error_message': False} if request.method == 'POST': # Insert MySQL query if 'student_name' in request.POST: try: insert_query = f"""INSERT … -
Django - Multiple File upload data not inserted in model database
I have implemented a feature to upload multiple files for each RetailerMaster(as foreign key). Once I migrate this model to microsoft sql server, FileUpload model is created without primary key which django should be creating automatically. Also if i upload multiple file, then only one record is created in database and it keeps on updating for each file. models.py class RetailerMaster(models.Model): id = models.PositiveIntegerField(unique=True) name = models.CharField(max_length=1000) address = models.CharField(max_length=4000) city = models.CharField(max_length=100) state = models.CharField(max_length=100) pincode = models.CharField(max_length=100) contact_name = models.CharField(max_length=500) email = models.EmailField() phone = models.CharField(max_length=15) erp = models.CharField(max_length=1000) remark = models.CharField(max_length=4000) def __str__(self): return self.id class FileUpload(models.Model): retailer = models.ForeignKey(RetailerMaster, on_delete=models.CASCADE), file = models.FileField(upload_to='files') file_upload_datetime = models.DateTimeField() file_name = models.CharField(max_length=1000) views.py retailer = RetailerMaster.objects.get(retailer_id=retailer_id) register_complete = retailer files = request.FILES.getlist('file') file_upload_datetime = file_upload_form.cleaned_data['file_upload_datetime'] for f in files: print(f.name) file_instance = FileUpload(register_complete.id,f,file_upload_datetime,f.name) file_instance.save() eg: If two files are uploaded 001.xlsx and 002.xlsx then below happens in database. As actual result, one record is inserted rather than two and same is updated with last file uploaded from multiple files. Can anyone help why record is not inserted but just updated. -
Login with django rest auth and mongodb
im very new to python and django. Currently experimenting on django-rest-auth and mongodb. So, im trying to set up a login and registration page. The registration works , ie save users in the DB, although i have this error TypeError at /rest-auth/registration/ Field 'id' expected a number but got ObjectId('6092cac59ab89b918140dcab'). From what i gathered, i should create a custom user model (or document?) and set a primary key so django does not add one? Back to the login issue, which is ValueError at /rest-auth/login/ save() prohibited to prevent data loss due to unsaved related object 'user'. The POST method does access the right collection in the DB , because i cannot login with invalid credentials. This error appear once i have successfully (?) logged in. After searching for a few hours, im nowhere. I found nothing, i dont know why the save() method would be called after a login. Ill be thankful for any pointers in the right direction. -
How to correctly configure Django to send emails with Gmail and what are the correct settings for the Gmail account?
I would appreciate some help with setting up Gmail with a Django application. I am trying to send send an email using gmail through Django to reset user passwords. My settings.py SMTP configuration is: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'myemail@gmail.com' EMAIL_HOST_PASWORD = 'mypassword' For the password I tried using both, the actual account password and the generated 16 digit password for apps which don't support 2-step authentication. I enabled the IMAP access and access for less secure apps in my gmail settings. I am still getting this error when trying to reset the password on my Django app: SMTPSenderRefused at /reset/ (530, b'5.7.0 Authentication Required. Learn more at\n5.7.0 https://support.google.com/mail/?p=WantAuthError s21sm6387949wmc.10 - gsmtp', 'webmaster@localhost') Any ideas what am I doing wrong? I am not sure if this is an issue with my configuration in Django or Gmail settings. Thanks in advance. -
Upload large video file in Django asynchronously

Creating A Checklist Template And Generating An Individual Checklist For Each User In Django
I am working on a project that incorporates a checklist for each new user. I had set it up so that the checklist is a model and used a foreignKey to associate the checklist with the correct user. I realize, however, that this would force me to re-create the checklist from scratch for each user. I would like, instead, to create a template with all of the ToDo items on it and then as users join the service a new instance of the checklist is created for them. I thought about doing a ManyToManyField for each checklist. This would probably mean, however, that if one user checks off one of their ToDos everyone's ToDo would then be checked. Any thoughts on this would be appreciated as I begin to figure this out. -
Does Python RQ or Django RQ use Multiple Processors?
I use Python RQ daily on an EC2 instance. One of the challenges my team is facing is that our team is relatively young in the Python space and unfamiliar with multithreading and multiprocessing. Currently we do everything on one core for a given request. Does Python RQ (and by extension Django RQ, the specific library we use), use multiprocessing? Does it use multiple cores? If not, is there a way we can achieve this? Should we set the number of workers to be the number of cores we have? -

What I really want is to swagger reflect correctly that the POST call does not need and id How can I do that?
