NoReverseMatch 在 /main/insert_num/ Django
我正在尝试制作一个 django Web 应用程序，该应用程序具有一个要求用户输入电话号码并将该号码存储在 postgres 数据库中的表单。以下代码给了我错误：
/main/insert_num/ 处的 NoReverseMatch
未找到“”的反向。'' 不是有效的视图函数或模式名称。
而且我无法弄清楚问题是什么，有人可以帮忙吗？

你views.py有点偏离 - 你没有在任何地方呈现你的表单。我起草了一个快速应用程序（我认为它可以满足您的需求） - 如果它有效，请告诉我：主/模板/index.html在这里，我只是将表单的操作设置为""（这就是您所需要的）并取消注释该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请注意这里的差异，我们正在测试请求类型并根据传入的请求类型采取适当的措施。如果是 POST 请求，我们将处理表单数据并保存到数据库中。如果没有，我们需要显示一个空白表格供用户填写。from django.shortcuts import render, redirectfrom .forms import HomeFormdef 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})让我知道这是否有效！
