Question

我在Web应用程序上有一个表单，用于获取数据并将其存储到数据库中。问题是：我正在使用不同的字段以及2个日期字段。当我从“模型和表单”中删除2个日期字段时，表单数据很容易存储到数据库中，但是当再次添加到“模型和表单”中时，它并没有将任何内容保存到数据库中。

型号：

name = models.CharField('Name', max_length=50, help_text='Co-worker name.')
    email = models.EmailField('Email', help_text='Co-worker email.')
    address = models.TextField('Address', help_text='Co-worker address.')
    phone = models.CharField('Phone Number', max_length=20, help_text='Co-worker phone number.')
    companyName = models.CharField('Company Name', max_length=80, help_text='Co-worker company name.', null=True,
                                   blank=True)
    workingLocation = models.CharField('Working Location', max_length=50,
                                       help_text='Co-worker working '
                                                 'location.')
    workingShift = models.CharField('Working Shift', max_length=50, help_text='Co-worker working shift.', default='')
    workingSpace = models.CharField('Working Space', max_length=50, help_text='Co-worker working space.', default='')
    teamMembers = models.CharField('Team Members', max_length=15, help_text="Co-Worker's Team Size.", default='')
    coworkerPicture = models.ImageField('Co-Worker Picture', upload_to='../media/images/co-woker-pictures'
                                        , help_text='Co-worker Picture.', default='profile_pics/default.jpg', )
    joiningDate = models.DateField('Joining Date', help_text='Joining Date of Co-worker',default=date.today,
                                    )
    dob = models.DateField('Date of Birth', help_text='Date of Birth of Co-worker',  default=date.today,

查看：

def Coworkers(request):
    # If user is not logged In
    if not request.user.is_authenticated:
        return redirect('login')

    if request.method == 'POST':
        form = addCoWorkerForm(request.POST, request.FILES)
        print(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, 'Co-Worker added successfully.')
            return redirect('admin/co-workers')

   c = context = ({
    'form': form,
    })

   # Render the HTML template co_workers.html
    return render(request, 'dashboard/co_workers.html', c)

表格：

class addCoWorkerForm(forms.ModelForm):
    name = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Name',
        'required': 'True'
    }))
    email = forms.EmailField(widget=forms.EmailInput(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Email',
        'required': 'True'

    }))
    address = forms.CharField(widget=forms.Textarea(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Address',
        'rows': '4'

    }))
    companyName = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Company Name',

    }))
    phone = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Phone Number',
        'required': 'True'
    }))
    CHOICES = [('Choose working location..', 'Choose working location..'),
               ('Islamabad', 'Islamabad'),
               ('Rawalpindi', 'Rawalpindi')]
    workingLocation = forms.ChoiceField(choices=CHOICES, widget=forms.Select(attrs={
        'class': 'form-control formInput',
        'required': 'True',
    }))
    CHOICES = [('Choose working shift..', 'Choose working shift..'),
               ('Day Time', 'Day Time'),
               ('Night', 'Night')]
    workingShift = forms.ChoiceField(choices=CHOICES, widget=forms.Select(attrs={
        'class': 'form-control formInput',
        'required': 'True',
    }))
    CHOICES = [('Choose working space..', 'Choose working space..'),
               ('Shared Space', 'Shared Space'),
               ('Private Room', 'Private Room')]
    workingSpace = forms.ChoiceField(choices=CHOICES, widget=forms.Select(attrs={
        'class': 'form-control formInput',
        'required': 'True',
    }))
    teamMembers = forms.CharField(widget=forms.TextInput(attrs={
        'class': 'form-control formInput',
        'placeholder': 'Team Members',
        'required': 'True'
    }))
    coworkerPicture = forms.ImageField(widget=forms.FileInput(attrs={
        'class': 'form-control formInput',
    }))
    joiningDate = forms.DateField(widget=forms.DateInput(attrs={
        'class': 'form-control formInput',
        'id': 'datePicker',
        'input_formats': ['%d/%m/%Y %H:%M']
    }))
    dob = forms.DateField(widget=forms.DateInput(attrs={
        'class': 'form-control formInput',
        'id': 'datePicker',
        'input_formats': ['%d/%m/%Y %H:%M']
    }))

       class Meta:
        model = CoWorker_Data
        fields = '__all__'

请给我建议解决方法。

Answer 1

您的input_formats用于DateTimeField，但是您已将字段定义为仅DateField，因此，请在此处进行如下更改：

  joiningDate = forms.DateField(widget=forms.DateInput(attrs={
        'class': 'form-control formInput',
        'id': 'datePicker',
        input_formats= settings.DATE_INPUT_FORMATS
    }))

编辑：如果要在settings.py中定义date_input_format，则应这样定义

DATE_INPUT_FORMATS = ['%d/%m/%Y']

注意：settings.py中的DATE_INPUT_FORMATS对USE_I18N = True无效。

Django表单数据未保存到databsae中
