如何排除[vanilla django]表单中的字段?

有两类用户存在投资者和管理者。一些用户(投资者)应该能够提出投资者类型而其他人(经理)不应该...我有一个表格。 UserInfoForm。而我只是想知道是否有一种简单的方法可以排除那些经理用户填写该字段。

在我的模板中,我成功地将管理员排除在查看investor_type字段之外。但是在提交UserInfoForm时,会出现:模板中的investor_type This field is required.

我有什么方法可以投入,必须=只对投资者真实吗?

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'),但没有用。

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))

我感谢您的帮助,并提前感谢您。

我会将投资者类型设置为:

required=False

然后为表单创建一个干净的方法,以检查用户的类型。如果它是投资者并且他们没有指定投资者类型则抛出错误。如果是经理让它通过。

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

使用表单的干净方法查看此文档。 https://docs.djangoproject.com/en/dev/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other
