Django：NoReverseMatch错误
[英]Django : NoReverseMatch error
问题描述
大家！
我是Django的新手，实际上是在做一个研究项目。 我收到了NoReverseMatch异常，无法理解原因。 似乎没有名称空间冲突，其他列表视图的创建方式与StoredItem模型相同，但只有此方法引发异常：
models.py：
from django.db import models
from django.urls import reverse
# Create your models here.
class LegalEntity(models.Model):
name = models.CharField(max_length=100, help_text="Name")
rif = models.CharField(max_length=10, help_text="RIF")
address = models.TextField(help_text="Address")
phone_num = models.CharField(max_length=15, help_text="Phone number")
def __str__(self):
pass
class Contract(models.Model):
name = models.CharField(max_length=100, help_text="Name")
number = models.CharField(max_length=50, help_text="Contract number")
description = models.TextField(help_text="Contract description")
start_date = models.DateField(null=False, blank=False, help_text="Start date")
expiry_date = models.DateField(null=True, blank=True, help_text="Expiry date")
def __str__(self):
return "number: {0}, " \
"name: \"{1}\", " \
"starts: {2}, " \
"expires: {3}."\
.format(self.number, self.name, self.start_date, self.expiry_date)
def get_absolute_url(self):
return reverse('contract-detail', args=[str(self.id)])
class Provider(LegalEntity):
contract = models.ForeignKey(Contract)
def __str__(self):
return "name: \"{0}\", " \
"RIF: {1}, " \
"phone: {2}."\
.format(self.name, self.rif, self.phone_num)
def get_absolute_url(self):
return reverse('provider-detail', args=[str(self.id)])
class Item(models.Model):
name = models.CharField(max_length=100, help_text="Name")
serial = models.CharField(max_length=50, help_text="Serial No.")
manufacturer = models.CharField(max_length=50, help_text="Manufacturer")
provider = models.ForeignKey(Provider)
def __str__(self):
return "name: \"{0}\", " \
"serial: {1}, " \
"manufacturer: {2}," \
"provider: {3}."\
.format(self.name, self.serial, self.manufacturer, self.provider.name)
def get_absolute_url(self):
return reverse('item-detail', args=[str(self.id)])
class StoredItem(models.Model):
item = models.ForeignKey(Item)
quantity = models.IntegerField(default=0)
def __str__(self):
return "{0} - {1}, {2} pcs.".format(self.item.serial, self.item.name, self.quantity)
def get_absolute_url(self):
return reverse('storeditem-detail', args=[str(self.id)])

这是我收到的消息：
找不到“ storeditem-detail”的反面。 “ storeditem-detail”不是有效的视图函数或模式名称。

我发现今天几个小时偷走我的错误
错误在该行的storageitem_list.html中
<a href="{{storeditem.get_absolute_url}}"> {{ storeditem.item.serial }} </a>
而不是"{{storeditem.get_absolute_url}}" ，而必须是"{{storeditems.get_absolute_url}}"
