我在Django中有一个位置模型设置，我最初设置它，以便使用主键将URL设置为/ location / 3 /。但是客户想要改变它以使用位置名称的slug。我在模型中创建了一个slug字段。并更改了urls.py中的网址格式。
urlpatterns = [
url(r'^(?P<pk>[\w-]+)/$', views.LocationsSingleView.as_view(), name='detail'),
]
我可以很好地链接到他们。但是当它试图实际加载该页面时，我收到一个错误：
基数为10的int（）的文字无效：'eau-claire'
eau-claire是该地点的slu ..
Documentation对此没有任何说明。
很多有这个问题的人都有他们的观点。但我的观点非常简单。所以我不知道出了什么问题。以下是我的观点：
class LocationsSingleView(DetailView):
model = models.Location

您需要在网址格式中使用package project;
import java.util.Scanner;
public class Denim {
public static void main(String []args) {
Scanner scan = new Scanner(System.in);
System.out.println("What item of denim is in question?");
String str = scan.nextLine();
String str1 = str.toUpperCase();
String jeans = "JEANS";
String jeansp = "JEAN PANTS";
String tux = "CANADIAN TUXEDO";
String tux1 = "CANADIEN TUXEDO";
String tux2 = "CANADIAN TUX";
String tux3 = "CANADIEN TUX";
String jacket = "JACKET";
String jjacket = "JEAN JACKET";
String hat = "HAT";
String dhat = "DENIM BASEBALL HAT";
String bhat = "BASEBALL HAT";
String c = "C";
int jeanFactor = 9982;
double jacketFactor = 10466.25178;
double bottleFactor = 128/16.9;
double hatFactor = 314.1415;
if (str1.equals(jeans) || str1.equals(jeansp)){
System.out.println("How many pairs of jeans?");
int numj = scan.nextInt();
int gallonj = numj*jeanFactor;
System.out.println("Producing " + numj + " pairs of jeans would use: ");
System.out.println(gallonj + " gallons of water");
double bottlesj = gallonj*bottleFactor;
System.out.println(bottlesj + " bottles of water");}
else if ((str1.equals(tux)) || (str1.equals(tux1)) || (str1.equals(tux2)) ||(str.equals(tux3))){
System.out.println("How many tuxedos?");
int numt = scan.nextInt();
int gallontp = numt * jeanFactor;
double gallontj = numt * jacketFactor;
double gallont = gallontp + gallontj;
double bottlest = gallont*bottleFactor;
System.out.println("Producing " + numt +" " + c + str.substring(1,8) + " tuexedos would use: ");
System.out.println(gallont +" gallons of water.");
System.out.println(bottlest + " bottles of water");}
else if (str1.equals(jacket) || str.equals(jjacket)){
System.out.println("How many jackets?");
int numjj = scan.nextInt();
double gallonjj = numjj*jacketFactor;
double bottlesjj = numjj*bottleFactor;
System.out.println("Producing " + numjj + " jackets would use: ");
System.out.println(gallonjj + " gallons of water");
System.out.println(bottlesjj + " bottles of water");}
else if (str1.equals(hat) || str.equals(dhat) || str.equals(bhat)){
System.out.println("How many hats?");
int numh = scan.nextInt();
double gallonh = numh*hatFactor;
double bottlesh = numh*bottleFactor;
System.out.println("Producing " + numh + " jackets would use: ");
System.out.println(gallonh + " gallons of water");
System.out.println(bottlesh + " bottles of water");
}
}
}
而不是slug来告诉Django您想要通过slug查找。
