當需要最小長度的密碼時，Django無法提出錯誤

Question

我有一個允許用戶創建用戶帳戶的表單。我還強制密碼的最小長度爲8，如果違反，會引發錯誤。問題是，每當最小密碼長度爲8時，它不會引發錯誤。

有人可以幫助我。

def Registration(request): 
    form = UserRegistration() 
    if request.method =='POST': 
     form = UserRegistration(request.POST) 
     if form.is_valid(): 
      user = User.objects.create_user(
       username=form.cleaned_data['username'], 
       email=form.cleaned_data['email'], 
       password=form.cleaned_data['password'] 
       ) 
      user.is_active = True 
      user.save() 
      return render(request,'choose.html',{'form':form}) 

    return render(request, 'register.html', {'form': form},) 

我forms.py

class UserRegistration(forms.Form): 
    username = forms.CharField() 
    email = forms.EmailField(error_messages={'required':'Error Missing Field , Please Fill this Field'}) 

    password = forms.CharField(
    widget=forms.PasswordInput(render_value=False) 
    ) 

    MIN_LENGTH = 8 

    def clean_password(self): 
      password = self.cleaned_data['password'] 

      if len(password) > self.MIN_LENGTH: 
        raise forms.ValidationError("The new password must be at least %d characters long." % self.MIN_LENGTH) 

      return password 

我的模板

<form method ="POST"> 
    {% csrf_token %} 


<span id="error">{{form.username.errors}}</span> 
<span id="error2">{{form.email.errors}}</span> 
<span id="error3">{{form.password.errors}}</span> 

{{form.username}} 
{{form.email}} 
{{form.password}} 
    <input type = "submit" value= "save" id="box2"/> 
</form> 

Answer 1

您的if條件是不正確的：

而不是

if len(password) > self.MIN_LENGTH: 

使用

if len(password) <= self.MIN_LENGTH: 
       #<---- changed condition 

Answer 2

clean_new_password1將永遠不會被稱爲new_password1不是模型場，將其更改爲clean_password，或者叫超級覆蓋任何默認檢查
