python - 图像未在 Django 中更新

Question

请帮帮我。我正在尝试更新用户名和电子邮件已更新但图像未更新的配置文件。我的代码是....

profile.html

    <form method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        <fieldset class="form-group">
            <legend class="border-bottom mb-4">Profile Info</legend>
            {{ u_form|crispy }}
            {{ p_form|crispy }}
        </fieldset>
        <br>
        <div class="form-group">
            <button class="btn btn-outline-info" type="submit">Update</button>
        </div>
    </form>

views.py

@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(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'Account Successfully Updated!')
            return redirect('profile')

    else:
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST, instance=request.user.profile)

    context = {
        'u_form' : u_form,
        'p_form' : p_form
    }
    return render(request, 'users/profile.html', context)

表单.py

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image']

我认为您的问题在于 views.py。

首先，您正在检查检索 View 的方法是否为 POST。如果不是，则您正在使用不存在的 POST 数据初始化表单。我在下面为您简化了这一点。

其次，您没有将 POST 信息传递给第二个表单，只有文件部分。您是否尝试过更改 p_form 以采用如下两个参数？

@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'Account Successfully 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.html', context)
