我是Django的新手。以下是Django的版本和使用的数据库
Django版本：2.1.15，django pyodbc azure==1.11.90，使用的sql server 2012
django管理员启动项目项
目标：从用户@itemnumber&将该输入提供给
EXEC ValidateBusinessrule '@itemnumber'，并在html页面中显示结果设置.py连接
DATABASES =
{
'default':
{
'ENGINE': 'sql_server.pyodbc',
'NAME': 'ETP',
'HOST': '10.*.*.*',
'USER': '',
'PASSWORD': '',
'OPTIONS': {
'driver': 'ODBC Driver 13 for SQL Server',
}
}
}
项目。urls:
from django.urls import path
from django.urls import path from . import views
urlpatterns = [path(r'item/', views.itemnumber, name='index'), ]
print("hello1")
UPDATION::::::::::::::::::::::::::::
我是Django的新手，无法将用户输入映射到存储过程查询。
views.py
from django.db import connection
from django.shortcuts import render
from .forms import InputForm
def home_view(request):
print("woooooooooooo",request)
context1 ={}
context1['form']= InputForm()
print("context1::::", context1)
return render(request, "input.html", context1)
def itemnumber(request):
cursor = connection.cursor()
try:
itemnumber = "23241715"
C=cursor.execute(f"EXEC ValidateBusinessrule '0000000000{itemnumber}'")
print("c value",C)
result_set = cursor.fetchall()
print(result_set)
result_set1= [' {} '.format(x) for x in result_set]
print(result_set1)
context = {"row": result_set1}
print("lolllllllllll", context)
return render(request, "home.html", context)
finally:
cursor.close()
print("hello3")
forms.py
from django import forms
import re
# creating a form
class InputForm(forms.Form):
print("inside forms")
regex = re.compile('^([1-9]{8})$', re.UNICODE)
ENTER_ITEM_NUMBER= forms.RegexField(max_length=8, regex=regex,help_text=("Required 8 digits
between {0-9}."))
print("iiiiiiiiiiiiiiiiiiiiiiii",ENTER_ITEM_NUMBER)
#ENTER_ITEM_NUMBER = forms.IntegerField(max_length=8, label='ENTER ITEM NUMBER')
item/urls
from django.urls import path
from django.urls import include, path
#from django.urls import path
from . import views
urlpatterns = [
path('inputs/', views.home_view),

我很困惑如何将用户输入=ENTER_ITEM_NUMBER提供给定义项目编号(请求(。
这样一切都会好起来吗？
根据给定的代码示例，我假设您的存储过程将字符串作为参数，所以请尝试执行cursor.execute(f"EXEC ValidateBusinessrule '{itemnumber}'")。
Upd：要将结果列表传递给html模板，请考虑使用从django.shorcuts导入的render方法。更多信息在这里
