python - django.urls.exceptions.NoReverseMatch

问题描述

我是 Django 的新手。在代码中，“pembekal”是指供应商。当我单击“New stok”按钮时 - 它会创建新书或其他新项目，但它会给出如下错误：

django.urls.exceptions.NoReverseMatch: Reverse for 'stok_create' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['books/(?P<pk>[0-9]+)/create/$']

模型.py

from django.db import models
from django.contrib.auth.models import User

class Pembekal(models.Model):
    pembekal = models.CharField(max_length=50, unique=True)
    alamat = models.CharField(max_length=50)
    telefon = models.CharField(max_length=20)

    def __str__ (self):
        return self.pembekal

class Stok(models.Model):
    stok = models.CharField(max_length=50, unique=True)
    pembekal = models.ForeignKey(Pembekal, on_delete=models.CASCADE, related_name='stoks')

    def __str__ (self):
        return self.jenis_stok

这就是我目前使用的所有文件。非常感谢任何帮助。我正在使用 Ajax 渲染到 CRUD 应用程序。由于上述消息，不会弹出模态表单。多个文件可能有错误。请纠正我。谢谢
