Best practice using key stored in secret managers in django
I have db key stored in the aws secrets manager. My password is automatically generated and stored. const rdsCredentials: rds.Credentials = rds.Credentials.fromGeneratedSecret(dbInfos['user'],{secretName:`cdk-${targetEnv}-db-secret`}); const dbCluster = new rds.DatabaseCluster(this, 'Database', { engine: rds.DatabaseClusterEngine.auroraMysql({ version: rds.AuroraMysqlEngineVersion.VER_2_08_1 }), credentials: rdsCredentials, removalPolicy: cdk.RemovalPolicy.DESTROY, clusterIdentifier: dbInfos['cluster'], defaultDatabaseName :dbInfos['database'], instanceProps: { instanceType: ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE2, ec2.InstanceSize.SMALL), vpcSubnets: { subnetType: ec2.SubnetType.PRIVATE_ISOLATED, }, vpc, securityGroups:[mySecurityGroup], }, }); Now I can see the key in secrets manager and paste user/password in settings.config however it doesn't make use of secret manager. How can I use secret manager key in django ? -

How to join 3 or more than 3 models in one single query ORM?
I am having 4 models linked with a foreign key, username = None email = models.EmailField(('email address'), unique=True) phone_no = models.CharField(max_length=255, unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = CustomUserManager() def __str__(self): return self.email class personal_profile(models.Model): custom_user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) picture = models.ImageField(default='profile_image/pro.png', upload_to='profile_image', blank=True) role = models.CharField(max_length=255, blank=True, null=True) gender = models.CharField(max_length=255, blank=True, null=True) date_of_birth = models.DateField(blank=True, null=True) def __str__(self): return str(self.pk) class academia_profile(models.Model): custom_user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) education_or_certificate = models.CharField(max_length=255, blank=True, null=True) university = models.CharField(max_length=255, blank=True, null=True) def __str__(self): return str(self.pk) class contact_profile(models.Model): custom_user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) country = models.CharField(max_length=255, blank=True, null=True) state = models.CharField(max_length=255, blank=True, null=True) city = models.CharField(max_length=255, blank=True, null=True) def __str__(self): return str(self.pk) For extracting the data of those four models, I need to extract it by querying 4 times differently and then by passsing for different variables to HTML templates it something a hectic plus would be reducing the performance speed (I am sure!) My current queries be like user_base = CustomUser.objects.get(id=user_id) user_personal = personal_profile.objects.get(custom_user=user_id) academia = academia_profile.objects.get(custom_user=user_id) contact = contact_profile.objects.get(custom_user=user_id) Is it possible to get all of the four queries values in a single variable by hitting a single join query in ORM ? also, I want to extract just the country … -

How to clear user specific cache in django?
I am using Django2.2.2 and django_redis for the cache backend. I had implemented cache in my API view according to this gist, and my views are here. from django.utils.decorators import method_decorator from django.views.decorators.cache import cache_page from django.views.decorators.vary import vary_on_headers @method_decorator(cache_page(168 * 3600, key_prefix="posts")) @method_decorator(vary_on_headers("Authorization",)) def list(self, request, *args, **kwargs): return super(PostViewSet, self).list(request, *args, **kwargs) This method will cache the post list on the user basic for 7 days. I had a clear cache like this. from django.core.cache import cache cache.delete_many(keys=cache.keys("*.posts.*")) How can I delete only some specific user cache? I had tried django-clear-cache but it cleared all cache. Is there any technique for clearing the per-user cache? -
Counting many-to-many field returns wrong value (Django)
I have a model class Student: class Student(models.Model): ... and model class Course: class Course(models.Model) students = models.ManyToManyField(Student) I now want to filter Course based on number of Students associated with a course. I tried: Course.objects.annotate(student_count = Count('students')) But for some reason, student_count is always returning one. Let's say I create a course and add two students to it: s1 = Student.objects.create() s2 = Student.objects.create() m1 = Course.objects.create() m1.students.add(s1) m1.students.add(s2) print(Student.objects.all().first().students.count()) print(Student.objects.annotate(student_count = Count('students')).first().student_count Prints 2 1 Why are these two values different? How can I filter courses based on the number of students? -

Send disconnect message to WebSocket in Django Channels
I am using Django==3.2.5 and channels==3.0.4. In the consumers.py I am using WebsocketConsumer class. My disconnect() method is executed After disconnecting the socket, which means the disconnect method is unable to send a response to the socket.

How to clone the input value when cloning the form in JavaScript
I am trying to save multiple objects in one page using django formset. For example, when I want to input 5 objects in the each form, the "kinds" and "hour" field have different values for all 5 objects, and all 5 objects have the same value for the remaining fields. So I am using the django-formset. So, when cloning a form in django formset, I would like the input value to be cloned as well. After several searches I couldn't find a solution. I read that setting true in the clone method will clone the event handler and even the value, but the entered value will not be cloned. Should I get it in the request.POST method? (For reference, the date field uses the datetimepicker jquery, and the student field uses the chosen jquery that is easy to search in the dropdownlist.)

Need help: whitenoise seems to be preventing a Django app running on heroku
Please point me to the right direction with a Django app that I am trying to put on Heroku. The app runs locally (both with python manage.py run server and heroku local), but doesn't run on heroku. It seems the root problem stems from whitenoise and I get errors doing collectstatic. BTW, whitenoise setup was done following the steps here for using whitenoise with Django. (app repo is here.) Through various searches I found this that suggests setting the Node version on Heroku to use the same one used locally, but I am not using npm nor node. I tried the kill process tip from here, but that didn't help. Neither did heroku restart. Doing python manage.py collectstatic --noinput got me these error messages: Traceback (most recent call last): File "/Volumes/Volume2/dev/student_manage_csp/manage.py", line 22, in <module> main() File "/Volumes/Volume2/dev/student_manage_csp/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 425, in execute_from_command_line utility.execute() File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/__init__.py", line 419, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/base.py", line 373, in run_from_argv self.execute(*args, **cmd_options) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/core/management/base.py", line 417, in execute output = self.handle(*args, **options) File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 187, in handle collected = self.collect() File "/Volumes/Volume2/dev/student_manage_csp/venv/lib/python3.9/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 134, in collect raise processed whitenoise.storage.MissingFileError: The file 'admin-lte/plugins/pdfmake/FileSaver.min.js.map' could not be found … -

How to change the field name of Serialzed User Model on frontend in Django Rest Framework?
I am making a simple Login/Logout App using REST API in Django DRF. I am using the default User model for this behavior. In the Login API, I wanted to authenticate the user with email, hence I wrote the custom authentication using ModelBackend. Everything works fine. But, I want to change the word username to email in the front of the Login API. I tried using the source attribute, but it does not change. Is there any easy way to do it? I am looking for something like verbose_name, that is used in Django Models. My serializers.py is: class LoginSerializer(serializers.Serializer): username = serializers.CharField(source='Email') password = serializers.CharField() def validate(self, data): user = authenticate(**data) if user and user.is_active: return user raise serializers.ValidationError('Incorrect Credentials Passed.') Again, I am using the default User Model, and I don't want to overwrite/override/extend the User Model. I just want to change the name of the field username on the frontend to be shown as email. Any help will surely be appreciated.
