試圖讓用戶選擇生日 - django

Question

我在Django項目中有一個表單，並且我希望用戶輸入他的生日，以便我可以保存在數據庫中並在以後的項目中使用...

我有一個模型，我想創建一個Modelform，它會詢問日期，然後格式化並保存在數據庫中。我一直在試圖找出這3天，並無法得到它的工作......我不得不刪除我的數據庫文件大約5次，因爲它不工作，搞亂了數據庫...

當用戶提交表單時，回報是三個單獨的項目，其中包括dob_month，dob_day，dob_year和正確的日期信息。

這是我到目前爲止所做的。

models.py文件

class Profile(models.Model): 
    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 = models.DateField(auto_now_add=False, blank=True) 
    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 

這裏是forms.py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'] 

這裏是view.py文件（處理表單的具體DEF ...）

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 = form.cleaned_data.get("dob_month") 
       dob_day = form.cleaned_data.get("dob_day") 
       dob_year = form.cleaned_data.get("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) 

**更新第**

所以可以說我有類似下面的模式：

class Group(models.Model): 
    name = models.CharField(max_length = 25) 
    description = models.CharField(max_length = 250, null=True) 
    count = models.SmallIntegerField(default=1) 
    status = models.SmallIntegerField(choices=GROUP_STATUS_CHOICES, default=1) 
    reference_code = models.IntegerField(default=0) 

安迪有類似下面的模型形式：

class CreateGroupForm(forms.ModelForm): 
    class Meta: 
     model = Group 
     fields = ['name', 'count', 'description'] 

，並在用戶提交以下形式：

name : omar jandali 
count : 5 
description : random group 

那麼我可以通過以下方式處理表格：

form = CreateGroupForm(request.POST, instance=new_group) 
new_group = Group(
    name = name, 
    description = desciption, 
    count = count, 
    status = status, 
) 

或者我還需要分配清理過的數據......

您不需要做太多的工作來處理表單。使用Django Model窗體，大部分工作都是爲您完成的。如果你想創建一個新的記錄，確保您添加instance到窗體標籤，像這樣：

form = ProfileForm(request.POST, instance= new_profile) 

method.request添加然後前：

new_profile = Profile(
    user = ... 
    created = ... 
    ) 

其中「......」是價值您想要與該表單實例關聯。

擺脫new_profile = Profile.objects.create(...

基本上你需要設置不是由用戶在特定情況下提供的值，然後叫他們時就實例化形式。
