Python Django--仅显示用户创建的对象

我正在用遗留数据库构建Django应用程序。我有一个模型，LIST，它来自遗留数据库，不能真正更改。我也在使用标准的Django用户模型。理想情况下，这就是我希望发生的事情。用户注册，注册后重定向以创建新的列表对象。创建新的列表对象后，用户将重定向到一个视图，其中包含他们刚刚创建的列表对象中的数据。在随后的登录中，用户将返回到包含他们创建的列表对象数据的视图。截至目前，我已将用户模型扩展如下：

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    list_id = models.OneToOneField(List, null=True)

def create_profile(sender, instance, created, **kwargs):
    if created:
        profile, created = UserProfile.objects.get_or_create(user=instance)
    post_save.connect(create_profile, sender=User)

class ListForm(ModelForm):
    error_css_class = 'text-error'
    required_css_class = 'text-required'

    class Meta:
        model = models.List
        fields = ('t_handle', 'facebook_id', 'pinterest_id', 'yelp_id', 'foursquare_id', 'yipit_id', )

def user_signup(request):
    if request.method == 'POST':
        form = forms.UserSignupForm(data=request.POST)
        if form.is_valid():
            user = form.save()
            g = Group.objects.get(name='test_group')
            g.user_set.add(user)
            # log user in
            username = form.cleaned_data['username']
            password = form.cleaned_data['password1']
            user = authenticate(username=username, password=password)
            login(request, user)
            messages.success(request, u'Welcome to Social FollowUp')
            return redirect('user_create')
    else:
        form = forms.UserSignupForm()
    return TemplateResponse(request, 'user_signup.html', {
        'form': form,
    })

@login_required
@permission_required('')
def user_create(request):
    if request.method == 'POST':
        list_form = forms.ListForm(request.POST)
        if list_form.is_valid():
            list_create = list_form.save()
            messages.success(request, 'List {0} created'.format(list_create.list_id))
            return redirect(reverse('user_dashboard', args=(2,))) # 2 is just an example
    else:
        list_form = forms.ListForm()

    return TemplateResponse(request, 'dashboard/create.html', {'list_form': list_form,         })


def user_dashboard(request, list_id):
    try:
        list_id = models.List.objects.get(pk=list_id)
    except models.List.DoesNotExist:
        raise Http404
    return TemplateResponse(request, 'dashboard/view.html', {'list_id': list_id})

我的列表表单如下所示：

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    list_id = models.OneToOneField(List, null=True)

def create_profile(sender, instance, created, **kwargs):
    if created:
        profile, created = UserProfile.objects.get_or_create(user=instance)
    post_save.connect(create_profile, sender=User)

class ListForm(ModelForm):
    error_css_class = 'text-error'
    required_css_class = 'text-required'

    class Meta:
        model = models.List
        fields = ('t_handle', 'facebook_id', 'pinterest_id', 'yelp_id', 'foursquare_id', 'yipit_id', )

def user_signup(request):
    if request.method == 'POST':
        form = forms.UserSignupForm(data=request.POST)
        if form.is_valid():
            user = form.save()
            g = Group.objects.get(name='test_group')
            g.user_set.add(user)
            # log user in
            username = form.cleaned_data['username']
            password = form.cleaned_data['password1']
            user = authenticate(username=username, password=password)
            login(request, user)
            messages.success(request, u'Welcome to Social FollowUp')
            return redirect('user_create')
    else:
        form = forms.UserSignupForm()
    return TemplateResponse(request, 'user_signup.html', {
        'form': form,
    })

@login_required
@permission_required('')
def user_create(request):
    if request.method == 'POST':
        list_form = forms.ListForm(request.POST)
        if list_form.is_valid():
            list_create = list_form.save()
            messages.success(request, 'List {0} created'.format(list_create.list_id))
            return redirect(reverse('user_dashboard', args=(2,))) # 2 is just an example
    else:
        list_form = forms.ListForm()

    return TemplateResponse(request, 'dashboard/create.html', {'list_form': list_form,         })


def user_dashboard(request, list_id):
    try:
        list_id = models.List.objects.get(pk=list_id)
    except models.List.DoesNotExist:
        raise Http404
    return TemplateResponse(request, 'dashboard/view.html', {'list_id': list_id})

My views.py如下所示：

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    list_id = models.OneToOneField(List, null=True)

def create_profile(sender, instance, created, **kwargs):
    if created:
        profile, created = UserProfile.objects.get_or_create(user=instance)
    post_save.connect(create_profile, sender=User)

class ListForm(ModelForm):
    error_css_class = 'text-error'
    required_css_class = 'text-required'

    class Meta:
        model = models.List
        fields = ('t_handle', 'facebook_id', 'pinterest_id', 'yelp_id', 'foursquare_id', 'yipit_id', )

def user_signup(request):
    if request.method == 'POST':
        form = forms.UserSignupForm(data=request.POST)
        if form.is_valid():
            user = form.save()
            g = Group.objects.get(name='test_group')
            g.user_set.add(user)
            # log user in
            username = form.cleaned_data['username']
            password = form.cleaned_data['password1']
            user = authenticate(username=username, password=password)
            login(request, user)
            messages.success(request, u'Welcome to Social FollowUp')
            return redirect('user_create')
    else:
        form = forms.UserSignupForm()
    return TemplateResponse(request, 'user_signup.html', {
        'form': form,
    })

@login_required
@permission_required('')
def user_create(request):
    if request.method == 'POST':
        list_form = forms.ListForm(request.POST)
        if list_form.is_valid():
            list_create = list_form.save()
            messages.success(request, 'List {0} created'.format(list_create.list_id))
            return redirect(reverse('user_dashboard', args=(2,))) # 2 is just an example
    else:
        list_form = forms.ListForm()

    return TemplateResponse(request, 'dashboard/create.html', {'list_form': list_form,         })


def user_dashboard(request, list_id):
    try:
        list_id = models.List.objects.get(pk=list_id)
    except models.List.DoesNotExist:
        raise Http404
    return TemplateResponse(request, 'dashboard/view.html', {'list_id': list_id})

最后，my urls.py包含以下内容：

url(r'user/signup/$', views.user_signup, name='user_signup'),
url(r'u/dashboard/(?P<list_id>\d+)/$', views.user_dashboard, name='user_dashboard'),
url(r'u/list/create/$', views.user_create, name='user_create'),

url（r'user/signup/$，views.user\u signup，name='user\u signup'），
url（r'u/dashboard/（？P\d+/$），views.user\u dashboard，name='user\u dashboard'），
url（r'u/list/create/$，views.user\u create，name='user\u create'），

基本上我不知道如何让我想要的发生，发生。每当用户注册并创建列表对象时，列表id不会保存到我创建的userProfile表中。我甚至不能100%确定我需要那张桌子。有人能帮我吗？

在您的

用户创建视图中

def user_create(request):
    if request.method == 'POST':
        list_form = forms.ListForm(request.POST)
        if list_form.is_valid():
            list_create = list_form.save()
            messages.success(request, 'List {0} created'.format(list_create.list_id))
            up, _ = UserProfile.objects.get_or_create(user=request.user, list_id=list_create)
            return redirect(reverse('user_dashboard', args=(2,))) # 2 is just an example

    #rest of the code

基本上，您所需要做的就是创建一个userprofile对象
 你的列表表单看起来怎么样？我刚刚用我的列表表单更新了帖子。我得到一个
全局名称“UserProfile”没有定义
错误。我正在我的view.py文件中导入模型。我缺少什么？你需要从models import UserProfile中执行
操作
太棒了！总的来说：为什么我必须特别导入该模型，即使我正在导入模型？在我添加了它并从models.py文件中删除了信号之后，它工作得非常好。谢谢你最近帮了我很多忙，谢谢！好。。虽然您导入了文件，但您需要专门导入模型对象，这是一个很好的功能，因为它可以减少名称冲突时的混淆。您甚至可以从.models import*执行
