我正在嘗試制作一個 django Web 應用程序，該應用程序具有一個要求用戶輸入電話號碼并將該號碼存儲在 postgres 數據庫中的表單。以下代碼給了我錯誤：/main/insert_num/ 處的 NoReverseMatch未找到“”的反向。'' 不是有效的視圖函數或模式名稱。而且我無法弄清楚問題是什么，有人可以幫忙嗎？索引.html<html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Test Form 1</title></head><body> <form action="{% url 'insert_my_num' %}" method="post" autocomplete="off"> {% csrf_token %} <!-- {{ form.as_p }} --> <input type="submit" value="Send message"> </form></body></html>表格.pyfrom django import formsfrom phone_field import PhoneFieldfrom main.models import Postclass HomeForm(forms.ModelForm): phone = PhoneField() class Meta: model = Post fields = ('phone',)模型.pyfrom django.db import modelsfrom phone_field import PhoneFieldclass Post(models.Model): phone = PhoneField()主/urls.pyfrom django.urls import pathfrom . import viewsurlpatterns = [ path('insert_num/', views.insert_my_num,name='insert_my_num')]項目/urls.pyfrom django.contrib import adminfrom django.urls import path,includeurlpatterns = [ path('admin/', admin.site.urls), path('main/',include('main.urls'))]視圖.pydef insert_my_num(request: HttpRequest): phone = Post(request.POST.get('phone')) phone.save() return redirect('')

你views.py有點偏離 - 你沒有在任何地方呈現你的表單。我起草了一個快速應用程序（我認為它可以滿足您的需求） - 如果它有效，請告訴我：
主/模板/index.html
在這里，我只是將表單的操作設置為""（這就是您所需要的）并取消注釋該form.as_p行
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Test Form 1</title>
</head>
<body>
<form action="" method="post" autocomplete="off">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Send message">
</form>
</body>
</html>
主/views.py
請注意這里的差異，我們正在測試請求類型并根據傳入的請求類型采取適當的措施。如果是 POST 請求，我們將處理表單數據并保存到數據庫中。如果沒有，我們需要顯示一個空白表格供用戶填寫。
from django.shortcuts import render, redirect
from .forms import HomeForm
def insert_my_num(request):
# Check if this is a POST request
if request.method == 'POST':
# Create an instance of HomeForm and populate with the request data
form = HomeForm(request.POST)
# Check if it is valid
if form.is_valid():
# Process the form data - here we're just saving to the database
form.save()
# Redirect back to the same view (normally you'd redirect to a success page or something)
return redirect('insert_my_num')
# If this isn't a POST request, create a blank form
else:
form = HomeForm()
# Render the form
return render(request, 'index.html', {'form': form})
讓我知道這是否有效！
