/accounts/register/ 处的 RuntimeError 线程 'Thread-1' 中没有当前事件循环

Question

I want to implement an email verification in my django app so, I am using an external module verify_email in that there is a function called verify_email() to check whether an entered email address exists or not. In my view.py file I am checking if the mail is valid then a user is created but, the problem is the function verify_email() takes some time to get the result. I think we need to use some kind of await statement to wait for the result but I am getting errors like this when I try to use it normally.

This is the pypi project link.

def register(request):
    if(request.method == 'POST'):
        email = request.POST['email']
        password = request.POST['pass']
        username = request.POST['username']
        check = verify_email(email)
        
        if check:
            user = User.objects.create_user(username,email,password)
            user.save()
            return redirect('/')
        else:
            messages.info(request,'email invalid')
            return redirect('register')

Description of the error:

Environment:

    raise RuntimeError('There is no current event loop in thread %r.'

Exception Type: RuntimeError at /accounts/register/
Exception Value: There is no current event loop in thread 'Thread-1'.

Is there a way to use asyncio or any other ways to deal with this kind of error?

Answer 1

Do you really think that the user should proceed even without email verification? It usually takes atleast few seconds to verify email on any website, So that should not be a problem. And for Concurrent requests you don't need to worry because django handles them very efficiently.

And sorry, I didn't had enough reputation to comment:)
