问题描述

Django==1.10.5.我有一个问题 RelatedObjectDoesNotExist视图.py:

Django==1.10.5. I have a problem RelatedObjectDoesNotExist Views.py:

def register(request):
if request.method == 'POST':
    user_form = UserRegistrationForm(request.POST)

    if user_form.is_valid():
        # Create a new user object but avoid saving it yet
        new_user = user_form.save(commit=False)
        # Set the chosen password
        new_user.set_password(user_form.cleaned_data['password'])
        # Save the User object
        new_user.save()
        # Create the user profile
        profile = Profile.objects.create(user=new_user)
        return render(request,
                      'account/register_done.html',
                      {'new_user': new_user})
else:
    user_form = UserRegistrationForm()
return render(request, 'account/register.html', {'user_form': user_form})

和

@login_required
def edit(request):
    if request.method == 'POST':
        user_form = UserEditForm(instance=request.user,
                                 data=request.POST)
        profile_form = ProfileEditForm(instance=request.user.profile,
                                       data=request.POST,
                                       files=request.FILES)
        if user_form.is_valid() and profile_form.is_valid():
            user_form.save()
            profile_form.save()
    else:
       user_form = UserEditForm(instance=request.user)
       profile_form = ProfileEditForm(instance=request.user.profile)
    return render(request, 'account/edit.html', {'user_form': user_form,
                                             'profile_form': profile_form})

问题在于:profile_form = ProfileEditForm(instance=request.user.profile)

The problem is that: profile_form = ProfileEditForm(instance=request.user.profile)

推荐答案

我在这个特定的练习上有类似的经验.错误来自下面的代码

I have similar experience working on this particular exercise. The error is coming right from code below

Profile_form = ProfileForm(request.POST, instance=request.user.profile)

Profile_form = ProfileForm(request.POST, instance=request.user.profile)

我们试图让 "request.user.profile" 没有意识到模型中的 "User" 没有 "profile" 但 Profile 有一个 "User" .因此，获得个人资料"的更好方法是:

We are trying to get "request.user.profile" not realizing "User" in the model doesn't have a "profile" but a Profile has a"User" . Therefore a better way to get the "profile":

        profile = Profile(user=request.user)

因此您的编辑方法应该与此类似:

Hence your edit method should look close to this:

@login_required
def edit(request):

    profile = Profile(user=request.user)

    if request.method == 'POST':
        user_form = UserEditForm(instance=request.user,data=request.POST)
        profile_form = ProfileEditForm(instance=profile,
                       data=request.POST,
                       files=request.FILES)
        if user_form.is_valid() and profile_form.is_valid():
            user_form.save()
            profile_form.save()
            messages.success(request, 'Profile updated successfully')
    else:
        messages.success(request, 'Error updating your profile')
        user_form = UserEditForm(instance=request.user)
        profile_form = ProfileEditForm(instance=profile)
    return render(request,
                  'accounts/edit.html',
                  {'user_form': user_form,
                  'profile_form': profile_form})
