Django Filter: Filter two models and get output as xml file
I currently have these models in my models.py file: class category(models.Model): name = models.CharField(max_length=200) flag = models.BooleanField(default=True) def __str__(self): return self.name class security_incident(models.Model): asset = models.CharField(max_length=200) actor = models.CharField(max_length=200) action = models.CharField(max_length=200) cia = models.ForeignKey(category, on_delete=models.CASCADE) def __str__(self): return self.action class attack(models.Model): name = models.CharField(max_length=100) defense_mechanism = models.CharField(max_length=100) action = models.ForeignKey(security_incident, on_delete=models.CASCADE) def __str__(self): return self.name class adtree(models.Model): goal = models.CharField(max_length=200) security_incident = models.ManyToManyField(security_incident) attack = models.ManyToManyField(attack) def __str__(self): return self.goal The case is that a user should input a goal (adtree model) in a filter form and then select at least two checkboxes (categories - there are in total three of them: confidentiality, integrity and availability). The view should then check if it exists a match for the goal with asset in the security incident model ( ex. goal = database and asset = database). The filter(or the view, I am not sure where I should do this) should return all security incidents for the selected categories as well as the attacks and defense mechanisms from the attack model. The goal is to return this as a dictionary or string and from there serialize it into an xml output. Here is my current filters.py file: class ADTreeFilter(django_filters.FilterSet): goal = … -

ModuleNotFoundError: No module named 'learning_logs.settings' in Django

Commaseparated form field in django
Suppose I have a following fields class SomeField(forms.Charfield): def to_python(self, value): value = super().to_python(value) # some cleaning logic return value def validate(self, value): super().validate(value) #some logic class AnotherField(forms.Charfield): def to_python(self, value): value = super().to_python(value) # some cleaning logic return value def validate(self, value): super().validate(value) #some logic class CommaSeparatedSomeField(Field): base_class=SomeField class CommaSeparatedAnotherField(Field): base_class=AnotherField What is the best way to implement above CommaSeparated***Field, where comma-separated means just a text field, with comma-separated values? I tried to represent it with a CharField, splitted by commas, but now I need to validate and clean each value in a list using the base_class logic. Here I encountered a problem, since all logic is not class methods. -

Django logging PermissionError with TimedRotatingFileHandler
I am trying to make django create and rotate new logs every 10 minutes using TimedRotatingFileHandler. My settings is as follows: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'DEBUG', 'class':'logging.handlers.TimedRotatingFileHandler', 'filename': 'logs/site.log', 'backupCount': 10, 'when':'m', 'interval':10, }, }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'DEBUG', 'propagate': True, }, }, } The first log file is created successfully.

How to get Django to make some files public and media files private on AWS S3 (no 403 errors)?
I'm using boto3 and django-storages to serve files from AWS S3. I'd like my static files to be public but other files to be private. I've got it kinda sorta working but not quite. My static files are being served as if they're private, with a pre-signed key. In my template file when I use: <img src="{% static 'images/3d-house-nav-gray.png' %}"> instead of what I want <img src="https://mybucket.s3.amazonaws.com/static/images/3d-house-nav-gray.png"> I'm getting <img id="home-img" src="https://mybucket.s3.amazonaws.com/static/images/3d-house-nav-gray.png?AWSAccessKeyId=AKIA1234564LQ7X4EGHK&amp;Signature=123456gIBTFlTQKCexLo3UJmoPs%3D&amp;Expires=1621693552"> This actually works when the templates are rendered from the server as part of an HTTPResponse, but not when an image like this is simply included as part of, say, a .css file. In that case I'll get: Failed to load resource: the server responded with a status of 403 (Forbidden) (I find I can copy and paste the problematic image link and replace the &amp; with an & then I have access, a further mystery.)
