Django query optimisation: Get first and latest results
I have a Report model with a created date. I want to get the first and latest reports based on created date.

How do i detect the current domain name in django?
I want to design my web application to serve two different front-end templates depending on what domain the user enter my django application. So if the user enter aaa.com, it would serve front-end from app AAA_USA, but if the user enter from aaa.co.my, it would serve front-end from app AAA_MY. What is the best way to do this? I was thinking of "detecting the current domain name" and then simply add an if-else statements in the View functions. These two domains will be pointing to the same Nameservers that contains my Django app. -

A rent can be contacted by many user to buy. I want to show the list of all users that has contacted a specific rent. Should i create a UserAPIView and show over there or show list of users in RentDetail? Which one is the best design? Here is my model and serializer class Rental(models.Model): user = models.ForeignKey(User) name = models.CharField(max_length=300, blank=False, null=False) phone_number = models.PositiveIntegerField(null=False, blank=False) class Contact(models.Model): buyer = models.ForeignKey(User) rental = models.ForeignKey(Rental, related_name="rent") phone_number = models.PositiveIntegerField(null=False, blank=False) buyer_choice = models.CharField(choices=BUYER_CHOICES, max_length=1, null=False, blank=False) class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('username', 'email',) class RentalSerializer(serializers.ModelSerializer): user = serializers.ReadOnlyField(source='user.username') galleries = GallerySerializer(many=True) class Meta: model = Rental fields = ('__all__') class UserAPI(APIView): def get(self, request, format=None): """ List all the users """ reply = {} try: users = User.objects.all() reply['data'] = UserSerializer(users, many=True).data except: reply['data'] = [] return Response(reply, status.HTTP_200_OK) class RentAPIView(APIView): def get(self, request, token=None, format=None): """ Returns a list of rents (or just rent if token is given) """ reply = {} try: rents = Rental.objects.filter(user=request.user) buyer_id = self.request.query_params.get('buyer_id', None) if buyer_id: print ('buyer_id', buyer_id) rents = rents.filter(rent__buyer__id=buyer_id) if token: rent = rents.get(id=token) reply['data'] = RentalSerializer(rent).data else: reply['data'] = RentalSerializer(rents, many=True).data except Rental.DoesNotExist: return error.RequestedResourceNotFound().as_response() … -
Is it fine to handle complex string in url or better format it
I have data to be handled by urls.py. Those are strings, which have spaces comas and etc ALEKSEEV,%20%D0%A2%D1%83%D1%80%20%C2%AB%D0%9F%D1%8C%D1%8F%D0%BD%D0%BE%D0%B5%20%D1%81%D0%BE%D0%BB%D0%BD%D1%86%D0%B5%C2%BB So is it ok to handle such a string by complex regular expression, or is it better to get rid of all spaces and signs and make one more specific field in model for handling request? Why? -

Issue using Django to pass JSON to Javascript
I'm using Django to return a JsonResponse to a script that is supposed to handle JSON and get coordinates for me. There seems to be something wrong when I try and use the JSON information in the javascript. For example, if i try to use data.something , its undefined. Here is my View: def getTweets(request, tag): d = {'string': tag} req = tweets.objects.filter(tag = tag) data = serializers.serialize('json', req, fields=('coord')) data = JsonResponse(data, safe=False) print data return data And here is the part of the JS I am currently using: $('#searchButton').click(function(){ xmlhttp = new XMLHttpRequest(); var tag = document.getElementById('tagSearch').value; if(tag.substring(0,1) === '#'){tag=tag.substring(1,tag.length);} document.getElementById('tagSearch').value = ''; xmlhttp.onreadystatechange = function() { if (this.readyState === 4 && this.status === 200) { var data = JSON.parse(this.response); var pinColor = ''+(Math.random()*0xFFFFFF<<0).toString(16); ........... So, I am using JSON.parse(this.response) to get this from Django, which returns a string. But as I said, something is seemingly wrong or I am completely missing how to access this. This is from my Django server console: "[{\"model\": \"visualize.tweets\", \"pk\": 1, \"fields\": {\"coord\": \"-76.958123, 38.827518\"}}, {\"model\": \"visualize.tweets\", \"pk\": 3, \"fields\": {\"coord ": \"-96.958123, 48.827518\"}}]" And, what I want to be able to do (or something similar): var coordString = point['coord']; var x …
