database - 在 Django 中，我无法保存模型的新内容

Question

我又一次遇到了一个小问题，无法在 Django 中完成这项工作。但至少你们帮助我更好地理解了事情。

这是我的看法:

def editUserprofile(request):
rc = context_instance=RequestContext(request)
u=request.user
if request.method=='POST':
    form = UserProfileEdit(request.POST, request.FILES)
    if form.is_valid():
        u = UserProfile.objects.get(user=u)
        u.avatar = request.FILES['avatar']
        u.first_name = form.cleaned_data['first_name']
        u.last_name = form.cleaned_data['last_name']
        u.email = form.cleaned_data['email']
        u.country = form.cleaned_data['country']
        u.date_of_birth = form.cleaned_data['date_of_birth']
        u.save()
        return HttpResponseRedirect("/editprofile")

else:
    u = UserProfile.objects.get(user=u)
    form = UserProfileEdit()
return render_to_response('users/editprofile.html',
                         {'form':form, 'u':u},
                         rc)

没有错误，但我的模型没有被修改。这也是我的模板:

    <form method="POST" action=".">
    {% csrf_token %}

    {% if u.avatar %}
        <img src="{{ MEDIA_URL }}{{ u.avatar }}" height="80px" />
    {% else %}
        <p>You have no avatar</p>
    {% endif %}
        <p>Change Avatar: {{form.avatar}}</p>
    <br />
    {% if u.first_name %}
        <p>First Name: {{u.first_name}}</p>
    {% else %}
        <p>First Name: No first name added </p>
    {% endif %}
        <p>Modify:{{form.first_name}}</p>
    <br />
    {% if u.last_name %}
        <p>Last Name: {{u.last_name}}</p>
    {% else %}
        <p>Last Name: No last name added </p>
    {% endif %}
        <p>Modify:{{form.last_name}}</p>
    <br />
    {% if u.email %}
        <p>Email: {{ u.email }}</p>
    {% else %}
        <p>Email: No email added</p>
    {% endif %}
    <p>Modify:{{ form.email }}</p>
    <br />

    {% if u.date_of_birth %}
        <p>Date of birth: {{ u.date_of_birth }}
    {% else %}
        <p>Date of birth: No birthday added </p>
    {% endif %}
    <p>Modify:{{form.date_of_birth}}</p>
    <br />

    {% if u.country %}
        <p>Country: {{ u.country }}</p>
    {% else %}
        <p>Country: No Country added</p>
    {% endif %}
    <p>Modify:{{form.country}}</p>
    <br />

    <input type="submit" value="Save Changes">
</form>

希望你们能帮助我，伙计们..!

在您的表单验证中 form.is_valid() 是否为真？
