Zdravím vás, myslíme že přístup byl udělen jen pár lidem kteří odvádí dobrou práci, jelikož by bylo dost nebezpečné udělit přístup všem, tak pokud vas mohu poprosit obraťte se s žádostí na ně. A pokud uznaji za vhodné že je to potřeba, provedou opravu, nebo doplnění. Pokud se mýlím, tak mě kontaktujte a prenastavim pravidla přístupu.

 Dear Suthar,

 You saved my day. Once more, the chart is displayed but the date is
 not displayed on Xaxis. This how it is:

 Th codes are:
 def reqChart(request):
 current_date = date.today()
 days_before = date.today()-timedelta(days=30)
 datelist = Customer_Requests.objects.values("arrival_date").
 annotate(num_req=Count("request_name")).order_by('-arrival_date')[:
 20:-1]
 replist = list()
 sumdata = list()
 for listd in datelist:
 replist.append(listd['arrival_date'])

 arriva_days = {

Re: What's the preferred way to implement matching mechanism (radius distance search) in an uber-like app

[V. J]

Zdravím vás, přišel jsem o PC tak nejsem schopen dělat víc, vše dělám stále jen po telefonu, budu se snažit o to co chci a pokud se mi to povede bude to báječný, pokud bych dělal špatně věci, rád bych od vás zpětnou vazbu, děkuji vám a napíšeme si. Vašek JachimOdesláno z mého telefonu Huawei Původní zpráva Předmět: What's the preferred way to implement matching mechanism (radius distance search) in an uber-like appOdesílatel: Jose Chacón Komu: Django users Kopie: Hello, django newbie here. I'm from Peru, currently assigned to participate in the development of a  startup app. What this startup wants is to match business with truck drivers to transport stuff.  I was asked to implement a matching mechanism, firstly I have no idea how to do it but then an idea came to my mind. The requirement its that radius distance search should be increased every 40s when it doesn't found a driver ready to take it. And the search goes on until a driver accepts the incoming request ( i omitted this part in my code)  - or until there's no driver left in the database. So just for testing purposes, this returns true when it finds a driver near according to radius distance search   Here it is:def search_simulation():#first filter - i will apply some conditions to the model . Actual filter value for test purposesfirst_filter = TransportistaGeolocalizacion.objects.filter(transportista_id__gt=18)#parameterflag_found = Falsestart_time_search = timezone.now()km = 2#loopwhile not flag_found:#loop break conditionif(km == 10):break#logic to search for driverdiff = timezone.now() - start_time_searchif(diff.seconds > 20):  #every 20seconds ,distance radius increaseskm+=1start_time_search = timezone.now()print("New round")print("New radius: " + str(km))else:search_result = first_filter.annotate(distance=ExpressionWrapper(6371 * Acos(Cos(Radians(-12.17261550001))* Cos(Radians((F('latitud'* Cos(Radians((F('longitud'))) -   Radians(-77.0259502999))+ Sin(Radians(-12.17261550001))* Sin(Radians((F('latitud'),output_field=FloatField())).filter(distance__lte=km)if(len(search_result) > 0):print("Driver found!")flag_found=Trueelse:print("Failed search")return flag_foundProbably it sucks , I'm afraid its not gonna work when deployed due to concurrent requests ,etc.  so what i wanted is to get is some advice from you. I know it's a super basic implementation (sorry i'm not a django expert yet :c). If  you've done this before or you  know a  better solution to what i want to achieve, it'd like to know (also bc i'm afraid my boss also has no idea how to do it) . It'd mean a lot. Thanks in advance.
