投资者和经理有两种类型的用户。一些用户（投资者）应该能够填写investor_type，而其他用户（经理）不应该......我有一个表格。用户信息表。我只是想知道是否有一种简单的方法可以将那些经理用户排除在填写该字段之外。

在我的模板中，我成功地将经理排除在查看investor_type 字段之外。但是在提交他们的 UserInfoForm 时，会出现：investor_type This field is required.在模板中。

有什么方法可以说，required=True 只对投资者？

class UserInfoForm(forms.Form):
    choices = (('0', "Foundation"), ('1', "Financial/Bank"), ('2', "Pension"), ('3', "Endowment"),\
                ('4', "Government Pension"), ('5', "Family Office"), ('6', "Insurance Co."),\
                 ('7', "Corporation"), ('8', "Fund of Funds"), ('9', "Fund Manager"), ('10', "Asset Manager"), ('11', "Fundless Sponsor"))

    first_name = forms.CharField(widget=forms.TextInput(attrs={'class':'input-text'}), max_length=30)
    last_name = forms.CharField(widget=forms.TextInput(attrs={'class':'input-text'}), max_length=30)
    email = forms.EmailField(widget=forms.TextInput(attrs={'class':'input-text'}))
    about = forms.CharField(widget=forms.Textarea(attrs={'class':'input-text'}), required=False)
    country = forms.CharField(max_length=50, widget=forms.Select(choices=countries.COUNTRIES))
    avatar = forms.ImageField(required=False)
    investor_type = forms.CharField(max_length=4, widget=forms.Select(choices=choices))


def save(self, user, type):
    if type == 'manager':
        profile = ManagerProfile.objects.get(user=user)
    else:
        profile = InvestorProfile.objects.get(user=user)
        # // Tried this...
        if profile.investor_type != self.cleaned_data['investor_type']:
            profile.investor_type = self.cleaned_data['investor_type']
            profile_edited = True
        # // Failed
    user_edited = False
    if user.first_name != self.cleaned_data['first_name']:
        user.first_name = self.cleaned_data['first_name']
        user_edited = True
    if user.last_name != self.cleaned_data['last_name']:
        user.last_name = self.cleaned_data['last_name']
        user_edited = True
    if user.email != self.cleaned_data['email']:
        user.email = self.cleaned_data['email']
        user_edited = True
    if user_edited:
        user.save()
    profile_edited = False
    if profile.about != self.cleaned_data['about']:
        profile.about = self.cleaned_data['about']
        profile_edited = True
    if profile.country != self.cleaned_data['country']:
        profile.country = self.cleaned_data['country']
        profile_edited = True
    if profile_edited:
        profile.save()
    if self.cleaned_data['avatar']:
        avatar = self.cleaned_data['avatar']
        avatar.name = user.username + '.' + avatar.name.split('.')[-1]
        profile.avatar.save(avatar.name, avatar)

我试过investor_type = forms.CharField(max_length=4, required=False, widget=forms.Select(choices=choices), initial='0')了，没有用。

Views.py：在视图中尝试 = 失败。

@login_required        
def edit_profile(request, profile_type):
    if profile_type == 'investor':
        profile = InvestorProfile.objects.get(user=request.user)
    elif profile_type == 'manager':
        profile = ManagerProfile.objects.get(user=request.user)
    context = base_context(request)
    if request.method == 'POST':
        notify = "You have successfully updated your profile."
        user_info_form = UserInfoForm(request.POST, request.FILES)
        if user_info_form.is_valid():
            user_info_form.save(request.user, profile_type)
            return HttpResponseRedirect(request.POST.get('next', '/profile/' + profile_type + '/' + request.user.username + '/'))
    else:
        initial = {}
        initial['first_name'] = request.user.first_name
        initial['last_name'] = request.user.last_name
        initial['email'] = request.user.email
        initial['about'] = profile.about
        initial['country'] = profile.country
        initial['about'] = profile.about
        # // Tried this ...
        if profile_type == 'investor':
            initial['investor_type'] = profile.investor_type
        elif profile_type == 'manager':
            profile.investor_type.required = False
        # // Failed
        user_info_form = UserInfoForm(initial=initial)
    context['user_info_form'] = user_info_form
    context['profile_type'] = profile_type
    context['profile'] = profile
    return render_to_response('edit/profile.html', context, context_instance=RequestContext(request))

感谢您的帮助，并提前感谢您。

我会将投资者类型设置为：

required=False

然后为检查用户类型的表单创建一个干净的方法。如果它是投资者并且他们没有指定投资者类型，则会引发错误。如果是经理，就让它过去吧。

您还需要确保您的个人资料模型允许investor_type 为空白和空： https ://docs.djangoproject.com/en/dev/topics/db/models/#field-options

查看有关表单的 clean 方法的文档。 https://docs.djangoproject.com/en/dev/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other
