我正在尝试编写一个小型的Django系统。用户登录后,可以编辑和保存自己的个人资料信息。所涉及的字段是:用户名、电子邮件、名字、姓氏、网站和图片。
问题:无法更新图片(选择一张新图片并点击“更新”按钮后,它显示“未选择文件”。页面上显示的个人头像仍然是旧的)。但其他字段都可以正常更新。
以下是我的代码:
models.py:
class UserProfile(models.Model):
user = models.OneToOneField(User)
website = models.URLField(blank=True)
picture = models.ImageField(upload_to="profile_images", blank=True)
def __str__(self):
return self.user.username
forms.py:
class UserForm2(forms.ModelForm):
class Meta:
model = User
fields = ('username', 'email', 'first_name', 'last_name')
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('website', 'picture')
views.py:
@login_required
def update_user(request):
try:
user_profile = UserProfile.objects.get(user=request.user)
except UserProfile.DoesNotExist:
return HttpResponse("invalid user_profile!")
if request.method == "POST":
update_user_form = UserForm2(data=request.POST, instance=request.user)
update_profile_form = UserProfileForm(data=request.POST, instance=user_profile)
if update_user_form.is_valid() and update_profile_form.is_valid():
user = update_user_form.save()
profile = update_profile_form.save(commit=False)
profile.user = user
if 'picture' in request.FILES:
profile.picture = request.FILES['picture']
profile.save()
else:
print(update_user_form.errors, update_profile_form.errors)
else:
update_user_form = UserForm2(instance=request.user)
update_profile_form = UserProfileForm(instance=user_profile)
return render(request,
'userprofile/update_user.html',
{'update_user_form': update_user_form, 'update_profile_form': update_profile_form}
)
update_user.html:
<form id="update_user_form" method="POST" action="/userprofile/update_user/">
{% csrf_token %}
{{ update_user_form.as_p }}
{{ update_profile_form.as_p }}
<img src="{{ update_profile_form.instance.picture.url }}" />
<br />
<input type="SUBMIT" name="submit" value="Update"/>
</form>
如何使它正常工作?
