Django 预填表格

Question

我希望表单数据在第一次渲染时预填，初始参数完全不影响表单。当用户编辑个人资料时，我希望用户数据显示在表单中。

def profile_update(request):
    if request.method == 'POST':
        form = UpdateProfile(
            initial={'username': 'Hi there!'}, instance=request.user)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse('profile'))
    else:
        form = UpdateProfile()

    return render(request, 'users/profile_update.html', {'form': form})


class UpdateProfile(forms.ModelForm):
    email = forms.EmailField()
    img = forms.ImageField(label='img', required=False)

    class Meta:
        model = TbUser
        fields = ['username', 'img', 'email', 'cellphone', 'empno', 'real_name', 'nfc_id',
                  'sex', 'role', 'department']

如果是 GET 请求，您需要将 initial 传递给表单：

from django.shortcuts import redirect

def profile_update(request):
    if request.method == 'POST':
        form = UpdateProfile(<b>request.POST, request.FILES</b>, instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('profile')
    else:
        form = UpdateProfile(<b>initial={'username': 'Hi there!'}</b>)

    return render(request, 'users/profile_update.html', {'form': form})
