通过链接注册新用户时无法自动创建配置文件

Question

问题：

尚未通过“注册”链接（新用户注册）创建用户个人资料，但只能在管理页面中创建。

view.py

from django.shortcuts import render, redirect
from django.contrib import messages
from .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateForm
from django.contrib.auth.decorators import login_required

def register_view(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(request, f'Your account has been created!!!')
            return redirect('login')
    else:
        form = UserRegisterForm()
    return render(request, 'users/register_users.html', {'form': form})

@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!!!')
            return redirect('profile')
    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
    'u_form': u_form,
    'p_form': p_form
    }

    return render(request, 'users/profile_users.html',context)

• app.py施加的信号

代码有什么问题？ 提前道歉长代码，因为新手不知道问题出在哪里，因为积累了不同的方法。

Answer 1

我遇到了同样的问题，您必须在 AppConfig 类的 apps.py 中创建一个函数：

class AccountsConfig(AppConfig):
    name = 'accounts'

    # for signals.property
    def ready(self):
        import accounts.signals

Answer 2

Watch this

我认为您需要删除 form.save（）并投放此代码（在 if form.is_valid（）之后）

views.py

def register_view(request):
    ....
    <your_field_from_registration> = form.cleaned_data.get('<your_field_from_registration>')
    user = form.save(commit=False)
    user.save()
    profile = user.profile
    ....
    profile.<your_field_from_registration> = <your_field_from_registration>
    ....
    profile.save()
    ....
