Django (v4) request.META['REMOTE_ADDR'] not working anymore?
I had been using for years (Django 1.9 & Python 2.7) request.META dictionary and ['REMOTE_ADDR'] header to get client's IP address. I have recently moved to Django 4.1.5 and found out that my code is not able anymore to get client's IP address, so I had to use: x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') if x_forwarded_for: ip = x_forwarded_for.split(',')[0] else: ip = request.META.get('REMOTE_ADDR') return ip which works fine. I've tested my old code in development mode and tried to log request.META.get('REMOTE_ADDR'). The code will log IP only if the IP address is localhost (127.0.0.1). With any other IP address, REMOTE_ADDR header stays blank. I'm just curious, could someone tell me why this is happening? -
Greater than for INET IP address field in PostgreSQL Version > 9

Creating a custom serializer in django
I am facing a problem, because I have to create a custom serializer to fulfill my needs. These are my models: class PublicID(models.Model): TYPE_FIELDS = ( ('M', 'monkey'), ('A', 'alien'), ('P', 'person'), ) public_id = models.CharField(unique=True, max_length=48, editable=False) obj_type = models.CharField(choices=TYPE_FIELDS, max_length=1) class Request(models.Model): source = models.ForeignKey(PublicID, related_name='source_request_set', on_delete=models.CASCADE) dest = models.ForeignKey(PublicID, related_name='dest_request_set', on_delete=models.CASCADE) class Monkey(models.Model): nickname = models.CharField(max_length=255) public_id = models.OneToOneField(PublicID, related_name='monkey', blank=True, on_delete=models.CASCADE) class Alien(models.Model): alias = models.CharField(max_length=255) public_id = models.OneToOneField(PublicID, related_name='alien', blank=True, on_delete=models.CASCADE) class Person(models.Model): first_name = models.CharField(max_length=255) public_id = models.OneToOneField(PublicID, related_name='person', blank=True, on_delete=models.CASCADE) Note that all types of obj_types can send Request to every type of obj_types. e.g. we can have a Monkey which sends a request to an Alien through their unique PublicIDs. My Serializer looks like this: class RequestSerializer(serializers.ModelSerializer): class Meta: model = Request exclude = ['id'] def validate_source(self, value): obj_type = value.get('obj_type') if obj_type is None: raise serializers.ValidationError('`obj_type` field is required.') # other checks return value def validate_dest(self, value): obj_type = value.get('obj_type') if obj_type is None: raise serializers.ValidationError('`obj_type` field is required.') # other checks return value def run_validation(self, attrs): source = attrs.get('source') dest = attrs.get('dest') if source is None or dest is None: raise serializers.ValidationError('`source` and `dest` fields are ' 'required.') self.validate_source(source) self.validate_dest(dest) … -
