Django-Filter表单输出错误不工作

Question

我正在尝试显示搜索栏，当搜索将显示表单的条目。

然而，这并没有发生。我正在使用Django过滤器来过滤表单，以便最终客户能够搜索查询并找到所需的详细信息。

我将整个代码粘贴在下面，如果你认为有比这更好的方法来完成工作，请告诉我。

我也分享了Github仓库的链接，如果你想尝试看看错误。

我被这个错误困住了很长时间。非常需要帮助!!!!!

filters.py

import django_filters
from .models import *
from inventory_app.models import Form1

class ItemFilter(django_filters.FilterSet):
item = django_filters.CharFilter(field_name='item', lookup_expr='icontains')
class Meta:
model = Form1
fields = ['item']

models.py

from django.db import models
#from django.utils import timezone
# Create your models here.
class Form1(models.Model):
item = models.CharField(max_length=125)
quantity = models.IntegerField(default=0)
vendor = models.CharField(max_length=125)
inward = models.IntegerField(default=1234)
date = models.DateField()
def __str__(self):
return self.item
#  security_stamp_date = models.DateField(default=timezone.now)

>>> from django.db.models import Q
>>> queryset = User.objects.filter(
Q(first_name__startswith='R') | Q(last_name__startswith='D')
)
>>> queryset
<QuerySet [<User: Ricky>, <User: Ritesh>, <User: Radha>, <User: Raghu>, <User: rishab>]>
