How Can I check if logged in user profile information is updated in django models
I am working on a project in Django where I have a Profile Model with a Foreign Key field (OneToOne Relationship with User Model) called applicant and a status field which is set to 'Update' at default. Other fields like surname and othernames are also included in the Profile Model. class Profile(models.Model): applicant = models.OneToOneField(User, on_delete=models.CASCADE, null = True) surname = models.CharField(max_length=10, null=True) othernames = models.CharField(max_length=30, null=True) status = models.CharField(max_length=30, default='Update', null=True) def save(self, *args, **kwargs): self.profilestatus = 'Updated' super().save(*args, **kwargs) def __str__(self): return f'{self.applicant.username}-Profile' I want the system to check every logged in user if their profile information are not Updated, they should be redirected to the Profile Update page to update their profile first else they should be redirected to view their updated profile. def index(request): user = request.user.is_authenticated if request.user.is_authenticated and Profile.objects.get(applicant==user, status== 'Update'): return redirect('user-profile-update') else: return redirect('user-profile') context = { 'check_profile_update':check_profile_update, } return render(request, 'dashboard/index.html', context) I have ModelForm with a save method with automatically updates the satus field in Profile Model to Updated any time a user updates his or her profile information. Someone should kindly help me on the best way of solving this issue. Thanks -

Django-storages uploads to S3 causing Django to hang
How can I prevent blocking when uploading to S3 using django-storages? My webserver currently gets about 100TPS and I have 17 workers (8 core cpu). After a bit of investigation I believe it's user content being uploaded that causes my webserver to hang. Is there a way to use django-storages + S3 properly (that prevents the event loop from being blocked)? Or am I barking up the wrong tree? Or– do I simply need to continue scaling worker resources? -
Django Project database MongoDB deploy in Azure settings
I've completed the deployment of the Django project on Azure Web App. However, I am getting errors in DATABASES in settings.py In settings.py DATABASES = { 'default': { 'ENGINE': 'djongo', 'NAME': 'db-name', 'CLIENT': { 'host': 'mongodb+srv://<username>:<password>@<atlas cluster>/<myFirstDatabase>?retryWrites=true&w=majority' } } } However, Azure is unable to establish a connection with MongoDB.

Anyone who can assist me would be much appreciated; I need assistance with this difficulty. -
how to connect or acquire a connection to a blob storage via outbound proxy
curl -v -X GET 'https://outboundproxy.xx.net:8443/<Container_name>/<SAS>Token' -H 'Host: Azurestorage.blob.core.windows.net' -H "Rest of the curl headers" We have a outbound proxy inplace and all of the external connection has to go via an 'https://outboundproxy.xx.net:8443'. Hence, In the above curl command i have used host header to pass the actual storage account base url. Now, I want to replicate it using the python Azure blob SDK module but I am not sure how to structure the account url parameter. Any pointer or hint will be helpful -
Understanding slow Django performance
My webserver is scaling and I'm using Sentry Performance to try and better understand where things are slow. One thing that I don't quite understand is where the slowness might be coming from when the total reported query times are dramatically different than the time it takes to get a response. For example, one of my endpoints is taking 40s to finally get a response to the user. You'll see the total response time took an incredible 44,000ms even though all the work was done in about 1s (which is still slow, but not 44s slow). -

Running a django application on both the host machine and docker container at the same time
I have created a simple django application that has one endpoint /health/live and it returns a success message upon receiving a get request.

How to hide some fields if user not logged in Django?

django template language - if statement issues
i am kind of new to django and i ran into a problem i couldnt find a solution to. In a template i render data from a custom context processor. There i use a for loop over all the queried items and a if statement, that checks that the data belongs to the person that is currently logged in: {% for item in all_soli_accs %} {% if item.owner == request.user.get_username %} <a href="{% url 'url-soli-acc' item.soli_acc %} "> {{ item.soli_acc }} </a> {% endif %} {% endfor %} Weirdly, the if statement doesnt return "true", when it is supposed to. The rendering doesnt output anything. In order to debug it, i tried to render {{item.owner}} and {{request.user.get_username}} and check if there are errors. But rendered as a variable, they return the same output, which lets me assume that it is all fine. I am confused. Does anyone has a solution to that? Do you need further information? best regards -
How can I make an attribute associate automatically with User? django
I'm making a simple website using django. I've added a 'Comment' model to make a comment section on a blog post. I'd like to print out each of the 'date_added', 'text', and 'owner' attributes in html. class User_Comment(models.Model): topic = models.ForeignKey(Topic, on_delete=models.CASCADE) text = models.TextField() date_added = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.text I have problems with the 'owner' attribute. owner = models.ForeignKey(User, on_delete=models.CASCADE) if I try to make migrations with it, Django asks me to provide a default value. It is impossible to change a nullable field 'owner' on user_comment to non-nullable without providing a default. This is because the database needs something to populate existing rows. Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Ignore for now. Existing rows that contain NULL values will have to be handled manually, for example with a RunPython or RunSQL operation. 3) Quit and manually define a default value in models.py. If I add 'blank=True', 'null=True' parameters to the onwer attribute, the attribute works but it doesn't automatically associate with the owner when adding a comment. So I have to go to … -

PostgreSQL tweaks for faster huge DB cleanup
I have a Python-Django script that takes our production database (150GB) and removes a ton of stuff from it, basically leaving only last 2 weeks of data for development purposes and produces just 6GB database at the end. Currently this script takes about 36 hours to finish with the given computational cloud resources (rather small and cheap ones). I think that there should be some postgresql-based tweaks like disabling auto-vacuum or disabling the indexes rebuilding to speed this up. Are there any? -
