推荐答案
您的views.py有点差-您不会在任何地方渲染表单.我起草了一个快速应用程序(我认为它可以满足您的需求)-让我知道它是否有效:
Your views.py is a little off - you aren't rendering your form anywhere. I drafted up a quick app (which I think does what you're looking for) - let me know if this works:
main/templates/index.html
在这里，我只是将表单的动作设置为""(这是您在这里所需要的全部)，并取消了form.as_p行的注释
Here, I just set the form's action to "" (that's all you need here) and uncommented the form.as_p line
<html lang="en">
<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">

</head>
<body>
<form action="" method="post" autocomplete="off">
{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Send message">
</form>
</body>
</html>
main/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.如果没有，我们需要显示一个空白表格供用户填写.
Note the differences here, we are testing the request type and taking appropriate action based on what kind of request is coming in. If it's a POST request we process the form data and save to the database. If not, we need to display a blank form for the user to complete.
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})
让我知道是否可行！
