Question

我在django有一个项目，我正在创建一个简单的表单，允许用户创建一个简单的配置文件，询问姓名和出生日期和位置。我的出生日期出现了关键错误，我不确切知道原因。

我正在尝试收集数据并将其存储到稍后将其添加到数据库记录中。

这是视图文件：

cd = form.cleaned_data
first_name = cd['first_name']
last_name = cd['last_name']
dob_month = cd['dob_month']
dob_day = ['dob_day']
dob_year = ['dob_year']
city = cd['city']
state = cd['state']
phone = cd['phone']
privacy = cd['privacy']

以下是模型文件：

user = models.ForeignKey(User, on_delete=models.CASCADE)  # server
first_name = models.CharField(max_length=25, default='first')
last_name = models.CharField(max_length=25, default='last')
dob_month = models.IntegerField(default=0)
dob_day = models.IntegerField(default=0)
dob_year = models.IntegerField(default=0)
city = models.CharField(max_length=45)  # user
state = models.CharField(max_length=25, default='state')
phone = models.BigIntegerField(default=0)  # user
privacy = models.SmallIntegerField(default=1)  # user
created = models.DateTimeField(auto_now_add=True)  # server

这是表单文件：

class ProfileForm(forms.ModelForm):
    split_choices = (('1', 'public'),
                     ('2', 'private'))
    privacy = forms.TypedChoiceField(
        choices=split_choices, widget=forms.RadioSelect, coerce=int
    )
    dob = forms.DateField(widget=extras.SelectDateWidget)
    class Meta:
        model = Profile
        fields = ['first_name', 'last_name', 'dob', 'city', 'state', 'phone', 'privacy']

最后，这是我得到的错误：

    KeyError at /setup_profile/
    'dob_month'
    Request Method: POST
    Request URL:    http://127.0.0.1:8000/setup_profile/
    Django Version: 1.8.6
    Exception Type: KeyError
    Exception Value:    
    'dob_month'
    Exception Location: C:\Users\OmarJandali\Desktop\opentab\opentab\tab\views.py in profile_setup, line 292
first_name  'omar'

dob_month   '1'
dob_day     '23'
dob_year    '2024'

state       'ca'
phone       '9515343666'
privacy     '1'
submit      'submit'

更新：

这里是views.py文件，但问题在于cd [＆＃39; dobv_month＆＃39;]，但我不知道为什么错误来自那里。

def profile_setup(request):
    if 'username' not in request.session:
        return redirect('login')
    else:
        # the following is just going to grab the currently logged in user and
        # save the profile information to the appropriate user
        username = request.session['username']
        currentUser = User.objects.get(username = username)
        # the following is the provessing for the form where the user entered
        # the profile informaiton
        if request.method == 'POST':
            form = ProfileForm(request.POST)
            if form.is_valid():
                cd = form.cleaned_data
                first_name = cd['first_name']
                last_name = cd['last_name']
                dob_month = cd['dob_month']
                dob_day = ['dob_day']
                dob_year = ['dob_year']
                city = cd['city']
                state = cd['state']
                phone = cd['phone']
                privacy = cd['privacy']
                # this is the new record that is going to be created and saved
                new_profile = Profile.objects.create(
                    user = currentUser,
                    first_name = first_name,
                    last_name = last_name,
                    dob_month = dob_month,
                    dob_day = dob_day,
                    dob_year = dob_year,
                    city = city,
                    state = state,
                    phone = phone,
                    privacy = privacy,
                )
                return redirect('home_page')
        else:
            # this is what is going to be saved into the html file and used to
            # render the file
            form = ProfileForm()
            message = 'fill out form below'
            parameters = {
                'form':form,
                'currentUser':currentUser,
                'message':message,
            }
            return render(request, 'tabs/profile_setup.html', parameters)

我们假设您的型号名称为User。

forms.py：

from .models import User
class UserForm(forms.ModelForm):


    def __init__(self, *args, **kwargs):
        super(UserForm, self).__init__(*args, **kwargs)

    class Meta:
        model = User
        fields = '__all__'

和views.py：

def user_create(request):
    form = UserForm(request.POST or None)
    if request.method == 'POST':
        form = UserForm(request.POST or None)
        if not form.is_valid():
            print form.errors
            return render(request, 'user_create.html', {'form': form})
        else:
            first_name = form.cleaned_data.get("first_name")
            last_name = form.cleaned_data.get("last_name")
            # pass your extra fields here
            new_user = User.objects.create_user(
                user=user,
                first_name=first_name,
                last_name=last_name,
                )
            new_user.save()
            return redirect('where you want to redirect',)    
    return TemplateResponse(request, 'user_create.html')

最后用户将保存。
